Downgrade iPad Baseband 06.15.00 to 05.13.04 is Very Much Possible!

WARNING: DO NOT install the iPad baseband on the 3GS. The newer 3GS (week 36 & above of the year 2011 (Serial No:xx136xxxxx)) will DEFINITELY brick your device during 06.15 baseband flash. It has been confirmed to permanently damage the built-in radio hardware, thus rendering it useless pretty much forever. It doesn't matter whether you integrate it into a custom IPSW or use Redsn0w. As of now the only solution is to return to Apple store & get it replaced. The iPad BB unlock solution had its piece of happy times & now its over. So think twice. The older iP3GS's (week 35 & below) are safe. A more detailed discussion about this can be found at JailbreakQA.

MuscleNerd, who happens to be one of the core members of Dev-Team just confirmed that downgrade of iPad baseband 06.15.00 to 05.13.04 is very much possible and is 99% doable. Downgrading iPad baseband back to 05.13.04 will not only fix battery drainage issues but will also help iPhone 3GS/3G users to fix their broken GPS.

iPad Baseband Downgrade Possible Downgrade iPad Baseband 06.15.00 to 05.13.04 is Very Much Possible!

@Kamiela2010 the downgrade potential from 06.15 remains (in my mind) 99% doable, but other things always seem to preempt working on it

In reply to:

@MuscleNerd it seems you guys have no interest in fixing gps issues with 6.15.00. Am I right??

Back in November 2010, Dev-Team released Ultrasn0w 1.2 to unlock iPhone 3GS (Baseband: 04.26.98, 05.11.07, 05.12.01, 05.13.04, 06.15.00) and iPhone 4 (Baseband: 01.59.00) on iOS 4.1 & iOS 4.2.1. Those who were running 05.14.02 or 05.15.04 baseband on their iPhone 3GS/3G were given with an option to upgrade their baseband to iPad baseband 06.15.00 if they want to use Ultrasn0w 1.2 to unlock their iPhone. Upgrading to iPad baseband not only made some iPhone 3GS users to lose their GPS but they also faced severe battery drainage issues.

Upgrading your iPhone 3GS to iOS 4.3 upgrades its baseband to 05.16.01 and restoring stock iOS 4.3.1 upgrades its baseband to 05.16.02. As both of these basebands are < than iPad baseband, so practically it is possible to upgrade them to 06.15.00. Now if you are thinking about upgrading your iPhone 4 (02.10.04, 03.10.01 or 04.10.01) baseband to iPad baseband then don't be too smart because iPhone 3GS/3G basebands do not require SHSH blobs to flash iPad baseband but the iPhone 4 does :P

According to MuscleNerd, instead of working on the unlock of individual baseband (05.14, 05.15 or 05.16), he will devise a single downgrade method for all iPhone 3GS users running iPad baseband. In this way, those iPhone 3GS/3G users who have baseband 05.14.xx, 05.15.xx or 05.16.xx will be able to use Ultrasn0w 1.2 by first upgrading to iPad baseband and then downgrading back to the unlockable baseband 05.13.04.

Conclusion: If you are waiting for the unlock of iPhone 3GS 05.14, 05.15 or 05.16 baseband then forget about it. In either way you MUST first upgrade to iPad baseband and then downgrade back to baseband 05.13.04. The best method to upgrade your iPhone 3GS to iPad baseband is by using Sn0wbreeze 2.5.1. Just download Sn0wbreeze 2.5.1 from here and follow this guide to upgrade your baseband to iPad baseband. If you are on Mac, use Redsn0w 0.9.6b5 instead of using Sn0wbreeze.

    Wow this website is just a bunch of (pretty cleverly though I have to say, even the cut down sumary in Google results is pretty fluid reading but TOTALLY misleading because it reads that it is a workable solution to install the iPad baseband on a new bootrom 3gs when it is anything but. And come on an overwhelming portion of the comments are completely optimized for phrases and keywords that will give steller ratings though the content is covering nearly (maybe all the bases for all I know I can’t be bothered to 100% my observations) all the possibilities for a great hit rating especially the huge amounts of comments for a non forum based post. And the cross site linking is also bang on for Google points. I have noticed that when it comes to apple devices there is a large proportion of erroneous information when it comes to jailbreaking this that and the other that for noobies and those that haven’t been burned yet by this tactic to disuade people from jailbreaking and unlocking their devices by giving tutorials on how to create paperweights. Android is going to continue to crush Apple more and more due to the greed factor alone. I mean pay twice as much be able to do half as much with your device isn’t going to last. man the amount of people that I meet and talk to alone about these sorts of things is not much in itself (20-30+ people and maybe 5 or so converts to Android devices and that doesn’t include PC converts either) but it adds up when you take into account all the other people like myself. Man even once jailbroken you still have to buy all the apps that make the process worth the effort to do, and unless you have a degree in computer science it’s not anywhere near the level of most humans (myself included for a while till I get the hang of it) to accomplish even decent jailbroken keyboard layouts are pretty much just the same as stock bar a few colors. I could go on for a long time still but it’s likely going to fall on deaf ears, or be moderated out, or quicly lost in the slow pulse of bot generated comments and or SEO optimized comments so I’ll leave with my bitter taste and continue to crunch the tums I need to quell the indegestion from hemoraging money on a horrid line of damaged devices (screens mainly due to the abismal product design flaw of having the glass be the shock absorber for the inevitable drops that any i device will suffer and they are by far one of the slipperiest devices to hold till (if you are lucky enough) the scratches give the dang things some grip. But some Androids copied some of those great traits to garner more money from repairs or replacements. Bye bye hurrrumppfff…. (and yes my grammar suks I don’t have the drive to edit it all up neat sorry I have other things to do like find a real fix for this baseband issue so it doesn’t end up a parts phone, lol And go nutz spam my mail all ya like I couldn’t care less I’m used to the swath of flyers and scams that this email address I use has generated in the handful of sites I have used it with.

    Now with the new options to unlock a 3GS and any iPhone from AT&T it would be much appreciated to have a way to go back from 6.15.00 baseband
    It wasn’t meant for the iPhone and it causes problems

    Is May 2012 right now, and in fact there is people that care about it
    iPhone 5 is coming up, but 3GS will still be in production

    The TV Station CNBC has an artikle that AT&T will start unlocking Iphones wich are out of contrakt beginning at April 4, 2012. How does is affect us with  changed firmware and jaibreak on Ipad base band? Can we go back to original Apple firmware?

    hello again, i successfully upgraded to ios 5 with the new redsn0w with the ipad baseband and have successfully jailbreaked and unlocked my phone. now the only problem that i am experiencing is that when i start a memory intensive app or a app that requires to use my current location, the iphone loses all connectivity, 3g and wifi. i can’t seem to figure out the problem as i have tried using a sim that is on the correct carrier without the jailbreak but i am still losing connection.

    is any experiencing this? does anyone know why this might be happening and how i can solve it?

    thanks in advance.

    ok so you say “The newer 3GS (week 36 & above of the year 2011 (Serial No:xx136xxxxx)) will DEFINITELY brick your device during 06.15 baseband flash.” Ok, but to say if i upgrade my 3gs ‘week 42 of 2011′ to 6.15 to, then to downgrade 05.13, my questions is could that then unbrick the phone?

    Hi,

    I have an iPhone 3GS that has the following:
    iOS version: 4.1
    Serial Number: 88142******
    Firmware: 5.16.03

    Do we have any mechanism to unlock and jailbreak for this combination? Somewhere I read that for versions later than 35th week cannot be unlocked.

    thanks,

    I have an iphone 3g 32gb.
    I’ve had to jailbreak. But the guy’s ass used iphone baseband.
    Lost GPS. And the battery does not work more than 6 hours. I do not know if there’s something about it.
    The iphone is with version 6.15.00.
    Everything else works normal.

    You can restore the baseband?

    Thanks so much

    •  
      Carlos2 years, 7 months ago

      If it helps. I upgraded a 3GS (w ipadbb) with custom 5.0.1 and it fixed the battery drainage. Lasting less than a day, now lasts up to 4 days with no data or 3G connectivity. It’s not a fact yet but is very possible that some out there may be fixed as well.

      Hello,

      Hardware failure. Baseband IC is damaged. Confirmed. There is no way you can recover your iPhone. Even after restoring, 99% of users were out of luck. It is very rare issue. If it is in warranty, go for it. Otherwise, buy a new iPhone.

    Hi, i have an IPhone 3GS with IOS 4.1 and bb 06.15.00, jailbroken and unblocked. It was working fine like for 3 months, but suddenly, about 2 months ago, it started to show problems when trying to connect on 3G. When I try to get 3G connection, it always goes to No Service while on 2G (GSM / EDGE) works completly fine without any problems as usual.

    I’m wondering if any of you guys have seen this issue before, and if you know what could be causing it and how to fix it.

    Please I’ll appreciate any suggestion
    Thanx

    i have an iphone 3gs on 5.0.1 with baseband 05.16.05, no one has been able to help me unlock it and use it in Spain. I have installed cydia on it several times with even the newest redsn0w 09 10 b1. I have looked everywhere, can you help? I just want to unlock my phone, I’m even considering paying one of those sketchy website that somehow have miraculous ways to unlock it. help!

    •  
      Patrick2 years, 8 months ago

      Unfortunately, it seems that your baseband is not supported right now. Your choice now is to install the iPad baseband since that one is supported.

    Hi, any update about the iPad BB downgrade? Because I have done it to my iPhone 3G and I really wanto to use my GPS hahahah, and I have now a iPhone 3GS (BB 05.16.05), and I’ve looked for a JB and the only way it’s upgrade the BB to iPad’s BB and then unlock…

    Thankful.

    •  
      Patrick2 years, 8 months ago

      I don’t think there’s a method for you to downgrade your BB, the only way for you to unlock is just like you said is to upgrade your BB and unlock since it is supported.

    Is it possible to downgrade ipad baseband? Cause I want to factory unlock my 3GS (old bootrom), but I need to have “proper” baseband for 3gs (e.g. 05.16.05 for IOS5).

    Thanks for answers – it will help me a lot!!

    hello i was wondering if there is a way to update my iphone 3gs to ios 5. it is currently on ios 4.3.3 with the ipad baseband installed. i also do not need the ipad baseband unlock anymore because im with the right carrier now. so if there is a way to update to ios 5 and get rid of the ipad baseband please do share.

    •  
      Jacklord2 years, 8 months ago

      @wsiddiqui777 Hi,

      You can only upgrade your iPhone 3GS to iOS 5 if you have SHSH blobs saved. And yes you can upgrade to iOS 5 using custom IPSW which you can create using Redsn0w 0.9.9b8 but this functionality is only available to Mac OS X users. You can upgrade to iOS 5.0.1 w/o SHSH blobs.

      Hope that helps!

    I have an iphone running on 4.3.3 and baseband 04.11.08 can i downgrade only the baseband? I need unlock the phone using gevey sim card.
    I already read about that i need downgrade by itunes and after that i need use redsnow to create a custom IPSW to upgrade only the version and keep the same baseband. I hope someone you guys can help me. Thanks

      Pramod2 years, 9 months ago

      Once updated, you can never downgrade your BB unlike the iOS. There is no unlock for your device at the moment.

    how can i jb&unlock it safely?

    •  
      Pramod2 years, 9 months ago

      Yep, that’s precisely what I’m trying to convey here. You can follow the default steps mentioned here http://bit.ly/lccwoE to JB & unlock your device. The usual risks & consequences involved with updating your BB to the iPad’s BB still apply though. So make sure that your totally aware of them before your proceed.

    McLaren2 years, 9 months ago

    Thanks pramod :) for the reply… It’s sad though coz I cannot use my iphone ’til the downgrade release from dev-team… I’m quite confident that dev-team will release BB downgrade in time…

    Here in Philippines, also apple idevice technicians having a problem with this issue. They have their own 3GS and they’re using it as paper weight LOL… And in my hand now a quite expensive music player…

    Thanks againg m8 :)

    •  
      Pramod2 years, 9 months ago

      Well, even a tool like that will not help resolve your BB chip issue. Only a h/w fix can solve it because your BB chip is now practically useless / damaged.

  •  
    McLaren2 years, 9 months ago

    Thanks Pramod… If ever dev-team released a downgrade of BB from 6.15 to 5.13.04, is this going to save my iphone 3GS? I hope :(

      If ever – At the moment, that itself is a big question mark. :(

    McLaren2 years, 9 months ago

    Got the worst nightmare… My iPhone 3GS is f**ked up, I think. No wifi, no bluetooth, no IMEI nor ccid and it keps on restarting every 4 to 5 mins.

    Can’t sleep and can’t help thinkin that i may not be able to use my iphone for the rest of my life. I know this has something to do with my iOS downgrade to 4.1.. Originally 4.3.5. My iphone is week 38 of 2011.

    Iphone bought in US via AT&T by my sister then ship here in the Philippines.
    I’m Thinkin one of the 2 parts are failing…
    1. Battery
    2. Worst… Basband chip.

    If it’s baseband chip, it can be replaced, right? Battery is the simplest part to replace.
    By the way, baseband from 5.16.02 upgraded to iPad BB 6.15.00

    I hope a baseband cHip replacement will have my iphone back to its normal state…

    Need advise….thanks :)

    •  
      Pramod2 years, 9 months ago

      Unfortunately, only a replacement of your device from an Apple Store can fix your problem. There’s nothing else that can be done about this as your iP3GS is now bricked for life & I’m not sure if a BB chip replacement would help either. :(

    Travis2 years, 9 months ago

    With “dead” I mean it turned itself off (battery was more than 80%) with a little flash on the screen and now I can’t turn it back on. Nothing works, like there’s no battery. Totally dead. Is there anything I can do? When I had a Windows 6.1 phone I used to hard reset the device from time to time. The device was working (except the GPS issue) flawlessy…(what Apple care would do if I’d send a jailbroken device to them?)

    Thanks again!

    EDIT: Hi Pramod,
    I have successfully restarted my iphone by holding down the home+on/off button. Rookie mistake! (sorry this is my first iphone). Anyway my iphone was built in the 37th week of 2010 but it didn’t give me problems regarding the ipad bb (except the gps issue): why?

    •  
      Pramod2 years, 9 months ago

      Yep, I have made the post more clear about that. Devices belonging to the year 2011 with week 36 & above are the ones affected by the radio loss issue. Yours belong to the year 2010, so you have no issues at all. :D

  •  
    John2 years, 9 months ago

    Hi Pramod. Yes I can personally vouch for it on several iPhones from my own testing. Others will confirm this.

    Hi Javox,
    I need help!
    I have a jailbroken 3gs on IOS 4.1 and ipad baseband. It worked fine for about 5 months but now the device seems dead. Nothing seems to work. What should I do to get it back to work? Cydia had saved both 4.1 and 4.3.5 shsh blobs.
    by the way I just found out my device serial number reads xx037xxxxxx : this is what your warning is referring to, right? I bought the device in Asia but not at an Apple Store (in fact it’s an AT&T device), I still have the receipt though…
    Thank you!!!

    Travis

    •  
      Pramod2 years, 9 months ago

      By stating that your device dead, does it mean that your radio is killed & that you now have no Wi-Fi / BT / GSM signals on your device? Do you have valid IMEI/BT/Wi-Fi addresses?

  •  
    John2 years, 9 months ago

    Not true. I can personally guaranteeredsn0w itself is not at fault.( snowbreeze, and redsnow) all use same baseband flash files and same tool (same as stock fw) and parameters- (it is actually covered in the link I sent you on the last page and confirmed) however whether or not you choose to believe that is up you, doesn’t change the situation

    Last post on this subject- Just thought it was worth tipping off

    Regards

    •  
      Pramod2 years, 9 months ago

      Using the same files still doesn’t necessarily mean that its actually the same way they are applied onto the device right? One applies it whilst a restore & the other doesn’t. All I’m asking you (for my personal checks only though I have already updated the posts with warnings) is whether a custom Sn0wB IPSW results in the BB loss or not. Can you personally vouch for it? Because this guy apparently can. Also that last question doesn’t answer it quite right. Once again, its not the matter of whom / what to believe, I double check my advices before I pass it on. :)

  •  
    John2 years, 9 months ago

    Both methods (sn0wbreeze/redsn0w) actually flash the baseband in exactly the same way. Here is more information

    http://jailbreakqa.com/questions/65072/after-3gs-baseband-update-615-phone-now-is-blank-imei-wifi-bluetooth

    •  
      Pramod2 years, 9 months ago

      I get that & I have scoured through the post as well with much detail, but it never really said anyone lost / crashed it due to Sn0wbreeze. There is no such reference because such a thing points to the fact that Redsn0w might be the one at fault here.

  •  
    John2 years, 9 months ago

    Jaxov Site admin- be warned newer 3gs(week 35 from testing so far) currently will CERTAINLY brick during 06.15 baseband flash, no matter whether you intgrate into IPSW or use redsn0w. As of know the only ‘solution’ is to return to Apple store You can search jailbreakqa, where user named ipHoneguy initially posted the info, gsm forum or email me- I can tell you what (little) I know about this subject so far

    Although this isn’t a new development and the answer hasn’t been found I think it would be tremendously helpful to post a warning regarding this as your blog has a fair amount of traffic from people interested in flashing and this could potentially stop them before bricking

    •  
      Pramod2 years, 9 months ago

      Yep, I have come across that post, but it all states the use of Redsn0w & not the integration of the iPad BB onto custom IPSWs. How did you confirm that?

      Nope, this kind of unlock is only for the iP3G/3GS.

    momo2 years, 9 months ago

    Hi, i have a 3gs with the ipad baseband on 4.3.3 and i was just wondering if i do not need the unlock on my 3gs anymore, would it be safe for me to upgrade my iphone with itunes to the factory ipsw? Im aware this will update the baseband but will it be harmful for my device. If it is i will wait foe the baseband downgrader to be released. Thnks in advance.

    •  
      Pramod2 years, 9 months ago

      Yes, you need to because if you by any chance update to the latest iOS, your BB gets updated as well & becomes unstable & unusable. You will need to always depend on an unlock no matter what if you are already on an iPad BB. You can always use a custom IPSW to update your iOS once a proper JB is out.

  •  
    Sam Mutawe2 years, 9 months ago

    Sure, forgot to mention that as well, we need not to forget the risks if we decided to do the ipad upgrade.

  •  
    Sam Mutawe2 years, 9 months ago

    Hi Guys, i believe any one with locked baseband should upgrade to Ipad baseband for one reason, that the Dev Team will not release unlock solutions for those basebands, instead the dev team will release a downgrade solution for the ipad baseband. So if this happens then anyone with locked baseband then has to upgrade their basebands to Ipad 6.15 then use the downgrade solution to get back to an unlockable baseband.

    •  
      Pramod2 years, 9 months ago

      You also need to keep all the risks involved in doing so as well. :(

    roboduke2 years, 9 months ago

    hi, nice article, i just bought a used iphone 3gs and now its running on 4.1 with the baseband 5.15. what you say it to not waste my time waiting for the hackers to unlock that baseband. should i or should i not, i really want to use that phone now, i dont have 3g internet so i wont be using the gps anyways and im not planning to sell my iphone anytime soon. maybe i should just upgrade the baseband to 6.15 and unlock it so i can use the phone. now its just and overpriced ipod touch to me. thank you

    •  
      Pramod2 years, 9 months ago

      To update / not is your call to make. Just make sure you think twice before you do so & make yourselves aware of the consequences following the same.

    Nicholas2 years, 9 months ago

    Dude u are the only that can save me.
    i did the ipad baseband upgrade but my iphone got stuck in a apple’s logo loop. so i put my iphone in DFU and used tiny umbrella’s Fix recovery. And now the screen is black !!! Dont know if the iphone is off or trying to turn it on. i opened itunes and discovery that the iphone was still in DFU mode so i restart it. Now is stuck with that fckng apple’s logo.

    What can i do ???
    plz help me !!!

    Thx in adv

    •  
      Pramod2 years, 9 months ago

      Did you by any chance recheck the Install Cydia option though you were already jailbroken prior to updating your BB via Redsn0w? Also, did you try using Redsn0w’s Fix Recovery option as well?

  •

    What do you recommend me to jailbreak with and when I do jailbreak can I use an official firmware to do so or which firmware would I use

    •  
      Pramod2 years, 10 months ago

      Use Redsn0w to JB your device. Redsn0w is always pointed to the stock iOS just like how Sn0wbreeze works.

  •

    So I finally got my 3GS new boot rom to update from 4.1 to 5.0 using snowbreeze and a custom firmware my problem now is that I do rely on a carrier unlock for tmobile and I can’t get passEd the iOS 5 activation is there a method to bypass and since it was snowbreeze custom will cydia be installed? This was my first time ever using snowbreeze I would have used redsnow but the windows version wouldnt let me create the custom firmware if u have a method I would highly appreciate it if u could tell me

      You need to pop-in the legit carrier SIM to which your phone was locked to & then hook it upto iTunes for activation. If you do not have one, you will then need to then JB your device,

      Pramod2 years, 10 months ago

      Is this an issue which occurs only when you use your headphones ? Does your headphones have a Mic?

    It works on, iPhone 3Gs, iOs 4.3.5, BB 05.16.02, right? :)
    Thanks for helping.
    Isnt there no other unlocking solutions than downgrading to iPad BB?
    And WILL there be other solutions?

      If your talking about the iPad BB upgrade then Yes. This is the ONLY possible way to unlock the current BB version that your running.

    Hello guys,

    I have an issue with my iphone 3GS it is already running IOS 5 but is running baseband 05.16.02, and well basically I did used sn0wbreeze-v2.8b8 to jailbreak the IOS and it worked just fine I have cydia installed and I can download and install apps just fine but the actual issue is that my cell phone does not get signal it just keeps searching and searching after I ran ultrasn0w…
    but I noticed that UltraSn0w only supports up to baseband 05.13.04 so is there anyway to fix this??? like downgrading to 05.13.04??

    thanks for your response in advance…

    •  
      Pramod2 years, 10 months ago

      You cannot downgrade your BB to an Ultrasn0w unlockable version once its updated. You need to get to the iPad BB if you want an unlock for your device. Make sure that your already aware of the risks / consequences of doing so. If you would still like to update your BB, you can use the latest version of Redsn0w. Read this http://bit.ly/lccwoE.

    is it possible to somehow update a 3GS to Ios 5 and get it unlocked with ios 5 the 3GS is on 4.1 with ipad bb 6:15

    •  
      Pramod2 years, 10 months ago

      Yes, by restoring to a custom iOS 5 IPSW. Use Redsn0w / Sn0wbreeze for the same.

    Hi, I have a 3GS on 6.15.00 running 4.2.1. I bought it jailbroken already, but I have a working AT&T sim card & data plan. I want to update to the ios5 and use it like a normal, non jailbroken phone. My friend told me I could just restore it and it would work. I tried connecting it to iTunes but when I went to restore, it wouldn’t go to ios5, just ios4.2. It says it’s up to date, which is weird, because the iTunes is 10.5. I’m not sure why i can’t get ios 5.

    •  
      Pramod2 years, 10 months ago

      Nope, you will not be able to use it as a non-jailbroken iPhone probably forever because your BB seems to have already been updated. For this BB to work, you still need to rely on Ultrasn0w for the unlock.

  •

    Funny, after more than 6 hours, it decided to work. But I’m having some other issues though. Every time I use Maps, it knocks my service on and off a million times. Especially if i’m trying to get directions. Also, I can’t find a solution to the t-mobile mms error that actually works. Do you have any solutions?

    •  
      Pramod2 years, 10 months ago

      That’s an issue with the iOS 5 JB which is fixed in the latest Redsn0w 0.9.9b7. Download it & rerun Redsn0w w/o checking any of the options over your existing JB.

      That’s your call to make now that your well aware of the risks involved.

  •  
    Martin2 years, 10 months ago

    Hi Pramod, yes these handsets were updated to official iOS (even though systemversion was spoofed so iTunes wouldn’t prompt a restore) and customer was warned not to update to stock, I have no problem with losing the unlock as this was obvious and customer ignored the advice , however the reception is now lost completely- even on official carrier after downgrade and, reflash iPad baseband through redsh0w or bbuodaterextreme/fuzzyband on stock 4.1, custom 4.1 or 4.33 IMEI/ICCID/ etc is intact, I’ve tested even using minicom + sendmodem to query baseband, send AT commands and no issues

    I’m surprised no more information is available on this problem, I have now received another unit, making a total of 4 iPhone 3GS i have seen in one week with an upgrade to iOS 5 seemingly knocking the signal off, surely I’m not the only one..

    •  
      Pramod2 years, 10 months ago

      Probably not, but this is just so weird. Its the first time I’m hearing something like this happening to a device because even the Dev-Team states that a reflash of the BB itself fixes everything.

  •  
    Nicholas2 years, 10 months ago

    i had the 3.1.2 ipsw and i updated to 4.3.5. After a long struggle, i managed to downgrade to 4.3.3 but my BB were updated to 5.16.02. Can i still downgrade my bb after i update to ipad BB ?

    im not using my phone for a long time because of that. Maybe i shouldnt have updated my iphone.

    •  
      Pramod2 years, 10 months ago

      Yep, you should have never updated your device using the stock iOS 4.3.5 IPSW via iTunes. Unfortunately updating to the iPad BB is a forever change & therefore there is no way for you to downgrade the same once updated.

      Redsn0w 0.9.9b7 still has that option available under the Jailbreak option. You might be just looking for it in the wrong place. Can you please elaborate on what is the problem that your facing?

    Martin2 years, 10 months ago

    I’ve had 3 iPhone 3GS within the past couple of days, stuck on iOS 5 activation screen after update (previously unlocked with ultrasn0w on 4.3.3 untethered, 06.15 baseband)

    The weird thing is, these units all display, no service, searching or a discrepancy with updating the carrier text when a sim is inserted or removed. Cannot activate with WiFi or using direct USB connection to iTunes

    4.33 SHSH is saved for all three units, so I’ve attempted downgrade in pwned DFU using custom firmware (tested to previously work),

    reflashed 06.15 baseband after update (not disconnected at any point, brand new win 7 install, iTunes and official Apple cable) and the issue still remains on ALL units.. ‘searching’- even original carrier SIM does not work. After ultrasn0w install there is no change, I have tried 3UK, O2, Vodafone, T-Mobile, Orange, Talk Mobile, Tesco Mobile, Virgin Mobile & Lebara. All sim cards activated and tested in another handset. No change

    I’ve also tried dowgrading to official 4.3.3 and official 4.1. using original SIM- phone will not activate, still same problem. checked hardware- all ok, Phone is not lost or stolen in checkmend database. These are all phones working perfectly on 4.3.3 jb + unlock with iPad baseband before iOS 5 update…

    I’ve also manually reflashed using BBupdatextreme/fuzzyband script, just out of ideas… the baseband or WiFi/ Bluetooth /IMEI is not greyed out, So it looks like the baseband is intact?

    Any ideas

    If you have any ideas why this behaviour is appearing

    •  
      Pramod2 years, 10 months ago

      Being an Ultrasn0w unlocker, did you update to the stock iOS 5 IPSW on all the 3 iP3GS’s directly from iTunes the first time?

  •  
    Exiphoner2 years, 10 months ago

    What really irritates me with this thread is that it bears little or no resemblance to the title anymore.

    It was meant to be about the possiblity of downgrading from 06.15.00 baseband and now its about everything but that.

    My brother updated my baseband to 06.15.00 and I didnt even want to unlock the phone, I dont give a monkeys about unlocking it and yet I’m still stuck with it even though “downgrade of iPad baseband 06.15.00 to 05.13.04 is very much possible and is 99% doable.”

    Either close the thread or keep it on topic as it’s just an almighty mess now.

    Finally managed to reflash my ipad BB but after unlocking with Ultrasn0w 1.2.4 i still have ‘No Service’. What IPSW do i select when am doing the ‘Just Reboot’ on Rednsow 0.9.9b7? iPhone2,1-5.0-9A334-Restore for 3GS or iPad1,1-3.22-7B500-Restore for iPad?

    •  
      Pramod2 years, 10 months ago

      The iOS that your currently running on your device. The iPhone IPSW.

  •  
    Steve2 years, 10 months ago

    Thanks mate. After updating to iOS 5 using itunes’ stock firmware, i created a custom firmware with Snowbreeze-v2.8b6 and restored via itunes to the custom firmware, used iBooty and installed Ultrasn0w 1.2.4 via Cydia to unlock. But there’s still ‘No Service’. So it appears the only option is to flash the BB. Redsnow has persistently failed to fetch the iPad baseband files, is it possible to manually point Redsnow to the iPad baseband?

    •  
      Pramod2 years, 10 months ago

      Why did you update your device using the stock iOS 5? Doing so has now updated your BB to a rathere unstable one & so you must now reflash your BB to the iPad’s BB once again to get back the unlock. Ultrasn0w will not work on the current BB config that your running. Try the reflash on a different PC.

    mamagic2 years, 10 months ago

    Hi Pramod,
    I just happened to get ip3gs with 4.3.5 and bb 05.16.02 locked and unjb.
    To make use of it I must have it unlocked (different carrier now). As from what I have read on web the only way is to dwngrade ios e.g. to ios4.1 and change bb to 06.15 and redsnow it.

    Q1. Launching Tinyumbrella I noticed that shsh for 4.1 and 5.0gm are still available – the previous owner saved them?). What is my true benefit having still access to shsh 4.1 since to have ip3gs unlock as I understand I have to update bb to 06.15 anyway. In the other words even if I am able to downgradefrom 4.3.5 to 4.1 I will not be able to unlock (redsnow) as having 05.16.02 bb I have to upgrade to ipad BB first anyway?

    Q2. Could I upgrade to ios 5 first and how I should then upgrade bb to ipad’s one and how to unlock it then pls? Are there any risks/downsides involved with that move, pls?

    Q3. As I understand the lost gps issue is solved with the latest redsnow 0.9.9 b6, correct? Is the battery drainage issue also solved, pls? and if not what are the ways to overcome that issues, pls?

    thx and best regards
    mamagic

    •  
      Pramod2 years, 10 months ago

      1. Yep, that’s right. You can downgrade to 4.1 to take advantage of an untethered JB because iOS 4.3.5 / 5 is still tethered.
      2. There are definitely risks & forever consequences in updating your BB to the iPad’s BB. Make sure that you aware of them first & then proceed. Google it if necessary. Use Redsn0w for updating your BB.
      3. Nope, the GPS / iPad BB issue was never resolved & it still exists.

  •  
    Steve2 years, 10 months ago

    Hi Pramod,
    I updated to iOS 5 on my 3GS and bricked it like all the many 3GS users. Jailbroke it with Redsnow 0.9.9b6 and Unlocked with Ultrasn0w 1.2.4 but there was ‘No Service’ still. So i tried to flash the 6.15 iPad baseband using Redsnow 0.9.9b6. However when i uncheck ‘Install Cydia’ and check ‘Install iPad baseband’ ‘Deactivate’ and click next, it shows ‘Fetching iPad baseband files’ and then shows ‘iPad baseband failed!’. What could i be doing wrong?

    •  
      Pramod2 years, 10 months ago

      iOS 5 never bricks your iP3GS. It restores your device completely w/o any failure. Because you updated to the stock IPSW (which you should have never done being an Ultrasn0w unlocker), your BB is now updated already to the stock iOS 5′s BB version. You need to flash your BB to the iPad BB once again to get it back onto 06.15.00. Make sure that nothing;s blocking Redsn0w from accessing the Apple servers & that your continuously connected to the internet.

    •  
      Pramod2 years, 10 months ago

      Ulrasn0w doesn’t support that BB version for an unlock. You need to update your BB to the iPad BB instead if you want an unlock which ofcourse comes with its own set of risks & consequences.

      What is your current BB version?

  •  
    Zappre2 years, 10 months ago

    Pramod, you seem like the guy in the know. I hope you won’t mind me asking your advice. I have a jailbroken 3g using Snowbreeze way back when. I didn’t unlock due to the warning about GPS and so my BB is 05.15.04. Now that I have a 4s, I want to use the old 3g as a travel phone so an unlock would be nice but I really don’t want to lose GPS and especially WiFi since I no longer have a data plan on the phone. I read one person’s experience maintaining his GPS & WiFi by jailbreaking to 4.1 instead of the 4.2.1 I currently have on it. From where I stand, is there a way to safely unlock without losing GPS & WiFi? I didn’t quite get the idea of upping the BB unlocking and then downgrading it. Does that keep the unlock? Confused newb here. Any help would be appreciated. Thanks.

    •  
      Pramod2 years, 10 months ago

      Unfortunately, the only way to get your device unlocked is by updating your BB to an iPad’s BB & therefore there is no guarantee that you will not loose your GPS / Wi-Fi right after the update is complete. Updating your BB is a forever change, so make sure that your ready to take the risks involved.

  •  
    Ron2 years, 10 months ago

    when i clicked on cydia, it told me to install two new updates then after it asked me to reboot my device. How do i upgrade to ios5 without having any of these problems?

    •  
      Pramod2 years, 10 months ago

      iOS 5 is currently a tethered JB. So, you need to be aware of the downfalls of a tethered JB. If you don’t want to boot your device each time you reboot / shut down, avoid jailbreaking it until an untethered JB is out for the same.

    The link I mentioned is found in this quote:

    “You still can update to iOS 5 by keeping your BB preserved at 06.15.00. You need to follow this http://bit.ly/oLQQk7. But keep in mind that you will still need a tethered JB. Nothing can be done about the GPS loss issue though.”

    I am running Version 5.0 (9A334) with Modem Firmware 06.15.00.

    I restored again to factory settings and tried the jailbreak again just to make sure that if it did erase the baseband, it could, but… I’m guessing it didn’t. And again, it’s still not getting service. There is Cydia on the phone, but it’s not allowing my sim card.

    •  
      Pramod2 years, 10 months ago

      Oops, my bad. Have you installed Ultrasn0w yet from Cydia to complete the JB? Jailbreaking alone isn’t enough.

    •  
      Pramod2 years, 10 months ago

      The 06.15.00 BB update option is only for the iP3GS. Use a Gevey SIM to unlock your iP4 at its current BB version.

  •  
    Ciara2 years, 10 months ago

    The link you gave is not for the ios 5 update. I also have a 3gs that now has the apple ios 5 on it that used to be jailbroken with ios 4.2.1 via ipad baseband. Clearly my jailbreak isn’t working because of that baseband. so what can i do?

    •  
      Pramod2 years, 10 months ago

      Ehm, which link are you talking about? Please do mention the same in your next reply.
      If you have restored to a stock verison of iOS 5, your BB is also updated I believe. Reply me back with your current iOS & BB config.

    •  
      Pramod2 years, 10 months ago

      What kind of changes are you thinking about? A restore is always a completely fresh install of the iOS on your device. So yes, it will erase everything from your device & make it a tethered JB as well.

  •  
    BRIAN MILLER2 years, 10 months ago

    well i think im giving up on the whole ipad baseband thing on my iphone 3GS 4.1 i really wanted to update to ios5 with the unlock but for whatever reason i guess it is not possible im calling verizon tomorow and getting an iphone 4 i pretty much hate the jailbreak stuff now its not really worth it to have an iphone on tmobile and to be stuck on 4.1 but of course i didnt really look into all of this when i bought the 3GS in the first place i just wanted an iphone ….its a shame i have a perfectly working iphone 3GS 32gb that i cant update or do anything cool with its quite the waste in my opinion it has no GPS problems or battery drainage issues ive had it for a year now with no update but its time to move on plus my contract with tmobile is up so its time to forget all this jailbreak unlock stuck brick edge 4.1 BS to anyone that wishes to have the iphone on TMOBILE ITS NOT WORTH IT!!!!!!!!!

    I also beleive that the jailbreak community potentially destroyed the iphone 3GS they could have found an unlock that worked with the iphone basebands instead of this 6:15 baseband………

    •  
      Pramod2 years, 10 months ago

      You still can update to iOS 5 by keeping your BB preserved at 06.15.00. You need to follow this http://bit.ly/oLQQk7. But keep in mind that you will still need a tethered JB. Nothing can be done about the GPS loss issue though.
      Also, you really need not blame the Dev-Team for the work they do for us out of their free time. You should have seen the GPS loss issues already coming & its not like they never mentioned about this on their blog or something. Their warnings are still all over the place & in every update of their tools. In the end, its you who did the update to the iPad BB for an unlock & lost the GPS, not the Dev-Team. Else, you should have continued with AT&T itself.

  •  
    jmt8882 years, 10 months ago

    Thank you. I know if you change the BB into 6.15 will lost the GPS function and would not change back into other firmware. That is the reason why I am still handing around not to unlock it. Do you think the Dev-Team will get something on it as I have learnt that they are working on it for a long long time ago. Thank you very much for your help.

    •

    I have a IPhone 3gs on 4.3.3 Ipad BB 6.15.00 that is jailbroken and unlocked using redsnow i relied on the unlock which is why i did it now my network said they have unlatched/unlocked the IPhone from there end i dont need the jb or unlock this way (it has killed my battery) i want to remove it. can i do that by upgrading successfully to IOS 5? as a fail safe will i be able to jb and unlock again by down grading back to 4.3.3? thanks so much for your help it was through your help back in june i was able to jb my phone at all!!

    •  
      Pramod2 years, 10 months ago

      Not possible to do so because the update made to the BB is a permanent one. So you would still need to rely on the unlock & still depend on the JB even though your factory unlocked now.

    •  
      Pramod2 years, 10 months ago

      You will enter into a recovery loop because of the iPad BB. You can solve it though, but then again you would still be tethered on iOS 4.3.5 as well.

    qvilorio2 years, 10 months ago

    I was mistaken there is NO SHSH 4.3.3 on Cydia, only 4.3.4 and 4.3.5. I’m now running 4.2.1 tethered, is there a way to put 4.2.1 unthered?

    •  
      Pramod2 years, 10 months ago

      Nope. Nothing you can do about that as well. Being tethered, you can’t even save your current 4.2.1 SHSH.

    One more thing, I use a Mac, which version of Pwertool do I have to use?. I only see SHSH for 4.3.4 and 4.3.5 saved on Cydia not 4.3.3, do I have to do the same thing with 4.3.4? or 4.3.5?

    Rgds,

    •  
      Pramod2 years, 10 months ago

      Where did you see the 4.3.3 SHSH ? W/o that, its useless to even try to update / restore your device. There’s absolutely nothing that you can do about it now.

  •  
    Mario2 years, 10 months ago

    Quick one for you. I have a 3gs on 4.3.5 what would i have to do to have it jailbroke? preferably unteathered. would i need to downgrade?
    thanks
    maz

    •  
      Pramod2 years, 10 months ago

      There isn’t one for the iOS 4.3.5 though you can still JB it tethered with Redsn0w 0.9.9b4. You would need to downgrade to iOS 4.1 to get an untethered JB.

  •  
    qvilorio2 years, 10 months ago

    Hello,

    Thanks for your answer. If I open Cydia I see SHSH: for 4.3.3, 4.3.4 and 4.3.5. And now?

    Rgds,

    •  
      Pramod2 years, 10 months ago

      All you need to do now is to create a custom 4.3.3 IPSW & restore to that. Use Sn0wbreeze http://bit.ly/mbFORU & restore to that in a pwned DFU mode. Make sure that you also set your hosts file to accept the Cydia server connections.

    Hello Pramod,

    I have a 3GS on 4.2.1, BB 6.15.00 on a tethered jailbreak and unlocked with ultrasn0w 1.2.3. I will like to get an untherered jailbreak, How can I do this? Do you think is worth going to 4.3.3 or 4.3.4 or 4.3.5. Thanks in advance for your help.

    •  
      Pramod2 years, 11 months ago

      First off, do you have the necessary SHSH saved for those / any other iOS versions via Cydia?

  •  
    Magneto2 years, 11 months ago

    One last chance for the downgrade is after the iOS5 event…when we don’t have the downgrade by that time, it’s bye bye baby (3GS) for me :/

  •  
    Exiphoner2 years, 11 months ago

    November 2010 they were saying they should be able to undo this.

    Well it’s a year of rumours of this and it is now being obvious that they dont have a clue how to undo it or simply cant be bothered.

    I’m gonna dump my iphone and get something better, a year of using my 3GS Brick is more than enough and I hate the 20 per week updates to the apple t&c’s.

  •  
    Dan2 years, 11 months ago

    For those with iOS 4.3.5 and baseband 05.16.02, might we expect unlock opportunities to open up with the release of the iPhone 5? I am wondering if there are any clever hackers out there who are waiting to release their new exploits until this event.

    Thanks for any tips that can be offered. I have moved to Europe a few days ago and am deciding whether to upgrade to the iPad baseband and potentially sacrifice a great amount of functionality.

    •  
      Pramod2 years, 11 months ago

      No ETAs on any of that, but yes there is always a good reason for why it isn’t out yet. Too much intel will always give Apple the leisurely time to fix them before a public iOS release or a new h/w is released. You really never know what’s next for the jailbreaking community, but yes there definitely are people actively working on iOS 5 exploits (Chronic-Dev) & to make life easire for us jailbreakers. So keep your fingers crossed. :D

    Mario Boccaccio2 years, 11 months ago

    So how come when I went to the phone shop near me and explained to the guy fully that I had upgraded to BB 6.15 and killed the GPS he said he could sort it for £25.00???? what did he mean by sort it out???and doubt he was gonna replace the BB chip.

    •  
      Pramod2 years, 11 months ago

      Have no real idea about what’s he going to do, but as far as the jailbreaks are concerned its impossible to downgrade your BB from the iPad BB once its updated.

  •  
    Pantyhouse2 years, 11 months ago

    HI again!

    I know i can return to the IOS but what am asking if today is possible to return to a previous version of BB once you have unlocked with the Ipad BB 6.15.00 and return to 5.13.04.
    I have saved some SHSH on my computer, but im not sure thats how you can return to the previous BB, maybe im wrong but anyhow please can you clarify me. And if you had a tutorial, that will be great

    THANKS!

    •  
      Pramod2 years, 11 months ago

      NO !! There is absolutely no way that you can downgrade your BB once its updated to the iPadBB ( 06.15.00 ) unlike the iOS versions. SHSH is ONLY for your iOS restores & nothing else.

  •  
    Curtie2 years, 11 months ago

    Hi again,

    The question I was asking wasn’t really whether it is possible to downgrade from iPad baseband on my iPhone 3GS. The question was whether it would be wiser to stay on iOS 4.2.1 and not upgrade to newer versions. The thought I had was that a solution might appear that makes it possible to downgrade e.g. from 4.2.1 but not from later versions. One could assume that Apple works hard on closing any holes that might present a way of downgrading…

    Thanks again for any views on this.

    Curtie

    •  
      Pramod2 years, 11 months ago

      Yea. But I guess I was too lazy to type it in again. (Though its still a correct reply you know :P )
      Ofcourse you can downgrade / restore your iOS versions if you have the necessary SHSH saved for your device / iOS except iOS 4.3.4+ & 4.3 versions because they are still tethered.

  •  
    Pantyhouse2 years, 11 months ago

    HI there, i had an Iphone 3gs with the following information:
    Version: 4.3.2 (8H7)
    Model: MC134E
    Baseband: 05.16.02
    It already jailbroken, but id like to unlock, i heard and read about the Ipad baseband on the other tutorial, but i couldnt fin any tutorial to return to baseband 05.13.04.
    So can i do the upgrade of the baseband, losing the GPS function, the return to baseband 05.13.04?
    Thanks a lot for yout time.

    •  
      Pramod2 years, 11 months ago

      No you cannot !! Read my previous reply to Curtie here on the same page. (Ignore the last sentence.)

  •  
    Neil2 years, 11 months ago

    Thank you very much for your help. I have not yet been able to try a different carriers sim card. I will do that as soon as I can. As far as restoring my iP3G (not an S) from my saved SHSH I don’t think I did because I dont know what an SHSH is. I am sorry for my ignorance. When I have read about SHSH blobs it looks to me like it is for 3GS but I am not sure what that even means (the SHSH blob)

    •  
      Pramod2 years, 11 months ago

      Oops !! Didn’t see that your having an iP3G. Well in that case, you need not worry about the SHSH either since the iP3G’s don’t require them for a restore.
      So, make sure that you do install a fresh custom 4.2.1 IPSW onto your iP3G & redo the unlock. That should solve your issue.

  •  
    Neil2 years, 11 months ago

    Thanks for your advice, I tried it 4 or 5 times. Even did the reset all from settings on the iphone, then reinstalled 4.2.1 and reinstalled the ultra snow. Tried my wifes sim card. Turned airplane mode on and then back off. Turn it off/on with sim card in/ with sim card out and every combination I could think of. I am sure I tried some more than once. Is there some way to diagnose the phone portion of my iphone? I am beginning to think maybe there is a hardware problem.

    Thanks Again,
    Neil

    •  
      Pramod2 years, 11 months ago

      Possible, but its too early to diagnose this as a h/w issue. What about a different carrier network SIM?
      Did you actually RESTORE your iP3GS via iTunes using your saved SHSH to a custom IPSW? I believe you haven’t.

  •  
    Scott2 years, 11 months ago

    I purchased A Holux 1200 gps – about the size of a pack of gum. Plugged it into the cigaret lighter adapter (included) and it sends a constant GPS signal to my iPhone. If I want to roam around I just unplug and throw it in my pocket. Not the most ideal but works well.

  •  
    Curtie2 years, 11 months ago

    Hi there,
    I have a question about an iPhone 3GS which has been upgraded to baseband 6.15.00 (big mistake). The loss of GPS is unbearable. I did want to carrier unlock the phone, but this is no longer of importance to me. What I am unsure about is whether I should upgrade from the current iOS 4.2.1 and whether this will affect the chances of removing the 6.15.00 baseband later on if a solution appears.
    Thanks for any views on this.
    Curtie

    •  
      Pramod2 years, 11 months ago

      No. There is absolutely no way that you can change / update / downgrade your BB once its updated to the iPadBB ( 06.15.00 ) unlike the iOS versions. Restoring / updating your iOS versions will never update the iPadBB either.

  •  
    Neil2 years, 11 months ago

    Hello again,

    my iphone 3g (jailbroke and unlocked 4.2.1 on 6.15 BB) had been working flawlessly for a month then today when I went into a meeting I turned the volume to the lowest setting (with the volume controls on the side) so if the phone rang it would not interupt. An hour or so later I went to send a text message and the phone said no service. I have not been able to get service back. my wifi works and all the other functions seem to work. I shut the phone off and restarted. I backed up and then restarted. I reloaded ultrasnow. I removed ultrasnow and then reloaded again (with shut downs in between) I put my tmobile sim in an old phone and it worked in the old phone. I put the non active att sim in the phone and it also said no service. I am running out of ideas and hope that you might be able to help.

    Thank you in advance!!!

    •  
      Pramod2 years, 11 months ago

      You might want to probably restore your device with a fresh custom 4.2.1 IPSW & redo the unlock. That should resolve your issue. Not quite sure as to why something like that would happen. Could be certain tweaks from Cydia or could be just anything.

    Iphone3gs fail2 years, 11 months ago

    Hello everyone. I have a 3GS with the iPad baseband and it is running 4.3.3 jailbroken and unlocked. The onl reason I upgraded the baseband was because my mom bought the phone not knowing it was locked in a different carrier than she had. Everything turned out fine, even the gps but shE was still experiencing battery drainage. So she bought another phone and gave me the 3gs. Since I am with the right carrier I don’t need the iPad baseband or the unlock and was wondering if there was a way to revert the baseband back because battery life is a problem for me. If there is a solution please let me know.
    Thanks in advance.

    •  
      Pramod2 years, 11 months ago

      Nope !! Its not possible to downgrade the BB once updated unlike the iOS. To resolve / minimize the battery drainage issues with the iPadBB, read this http://bit.ly/mootZv.

    Sorry for my english if is worst.
    Thank You

    •  
      Pramod2 years, 12 months ago

      What about the carrier network on which your on right now? Do they support 3G services within your area? Also, did you compare the same 3G functionality with others who are on the same network as well?

    Mario2 years, 12 months ago

    Hi Guy’s
    Hope you can help, Ok. I’ve got a 3Gs new botrom, FW 4.1 (8B117) jailbroke and unlocked. Problem I have is it’s been upgraded to BB 6.15.00 an now got “No Service” Take it that’s because of the baseband upgrade.

    Question I have is, How can I fix this issue??

    Is there any way I can make it a working phone again, please can some one help me with step by step instructions.
    Sorry to be a pain,
    Thanks in advance,
    Mario
    :)

    •  
      Pramod2 years, 12 months ago

      Have you completed the unlock procedure by installing Ultrasn0w? If not, go ahead & install the same from Cydia. If yes, then you might want to pop in a different SIM probably from a different carrier as well to see if the No Service issue still persists.

  •  
    Cyril3 years ago

    Hey there! My iPhone 3GS was jailbroken on 4.3.3 with a baseband of 6.15.00. Well a couple of days ago, I got the WSOD:( I figured out a way of fixing it.. Put my phone in DFU mode, updated to iOS 5beta 6 then put it in DFU mode again, run iReb and install jailbroken 4.3.3 with baseband 6.15.00. Then I installed ultrasn0w but it couldn’t find my carrier, just says searching then after a while no service… Also experiencing wifi problems (gets disconnected randomly, but still works). So after that I restored to stock 4.2.1 then installed custom 4.2.1 with iPad baseband. No wifi problem but unlock not working… What should I do?

    •  
      Pramod3 years ago

      Try the same with a different SIM belonging to a different carrier as well to see if the issue persists & that your able to get other service networks in your carrier list as well. Also, avoid reflashing your device with the iPad BB every now & then you restore your device. You needed to do that only once when you updated to iOS 5b6 & not every single restore.

    I have iphone 3gs on ipad baseband but the network signals are very weak all the time. Any suggestions to solve the issue please

    •  
      Pramod3 years ago

      Your bound to get such issues with the iPad BB because its something that’s meant to be run on an iPad instead of an iPhone. Make sure that your within a reasonable range of your carrier network / 3G coverage. Also, compare your iPhone with either of your friend’s as well.

  •  
    Someguy3 years ago

    I hope devteam bb downgrade comes out soon, when the 3G(s) stock bb reaches 06.15 or above we should be able to update & restore with iTunes stock, it seems this way will come sooner, I got my 3GS from a friend of a friend and I didn’t relies it had iPad bb and I got this rocovery loop and 1015, I managed to restore with custom 4.1 and all is good but lost my unlock, since I have not jailbroke it and have no problems with battery or gps, I got my unlock for free from vodafone, o2 charges £15, vodafone charges from free to £19.99, i think its worth the infinit carrier unlock, just waiting now for 06.15 bb downgrade to do stock update,

    Just asking to estimate when a working downgrade solution could arise?

    •  
      Pramod3 years ago

      No ETAs as of now. So don’t expect it anytime soon either. Probably it may never come by. So don’t get your hopes high.

    when will the iPad BB ever be downgraded from my iPhone 3GS? I’m still hoping that the time will come soon, or will I drop that hope already?

      Read my following comments. No ETA & don’t expect it anytime in the near future as well.

  •  
    cyman3 years ago

    Pramod, I am thinking of something. When you say “The loss of GPS is hit-miss chance” does it sounds that jailbreaking 3Gs again there is a chance that BB will not cause the problem and my phone would join those working fine (GPS) on BB 06.15?

    •  
      Pramod3 years ago

      Nope. That’s absolutely not what I meant. What I mean is the probability of loosing your GPS while you update your BB to 06.15.00 is always taking a chance with the GPS functionality of your iPhone.

      •  
        KevinW3 years ago

        Pramod, sorry for not getting the difference between what Cyman asked, and what you answered. Perhaps you could clarify? I thought Cyman was asking whether it was 100% certain that JB and upgrade BB to 06.15 would definitively remove GPS functionality, or whether there was the possibility of those who retained GPS functionality — perhaps I misunderstood him.

        Do you have any anecdotal evidence for how widespread the GPS failure is under 06.15? 30%, 50%, 90%?

        •  
          Pramod3 years ago

          Yes, & I said No. Its not necessary that you will loose the GPS functionality. Its always a hit/miss thing with the GPS functionality. There isn’t any certain probability rate or anything of such sort. Just expect it to be lost & continue with the update to the iPad’s BB. Once its lost, there isn’t any alternate way to get your GPS functionality back anytime now because 06.15.00 is meant to be run on the iPad & not on the iPhone & hence the complications.

  •  
    Giovanni3 years ago

    Scott – follow this video http://www.youtube.com/watch?v=3gxJrggEVI4

    It’s not a real workaround since you need a bluetooth GPS receiver, I have one at home from a few years back when my Nokia E-something did not have internal GPS.
    I remember I bought the received on ebay for a very small amount of money.
    Anyway I really hope the guys will come up with a BB downgrade in the next months.

    Scott3 years ago

    A few have posted that their GPS works fine after the iPad BB change. I notice that I get some navigation aid from my phone but as I’ve been experimenting with it I find that it gets no gps signal at all it just jumps from wifi to wifi – apparently, any and all wifi signals send their address (even if a locked signal) and this aids smartphone navigation. My iphone jumps from street to street as it can find a signal & when the wifi is turned off it triangulates (very poorly) using the towers. 3rd party apps show no GPS signal at all.

    I’ve read a few posts about folks using a seperate GPS unit with bluetooth to re-supply their iphone with a GPS signal (Holux M1200) – anytone tried this work around?

    •  
      Pramod3 years ago

      The loss of GPS is hit-miss chance that you need to take while updating your BB. The iPad’s BB is meant to run on an iPad & not on an iPhone & hence the GPS loss. Some are lucky to get through & some are not.

    Joosh3 years ago

    Sooooo much great info on here. Thanks everyone! Just downgraded 3G 6.15 4.2.1 to 3.1.3 to speed things back up. I have 2 questions. I used SAM prefs to fix batt drain when i was on 4.2.1, does this function the same on 3.1.3 or is there anything i need to do different to avoid problems? And #2 is there anything in cydia to be able to use apps that require ios 4.x.x but stay on 3.1.3? Thank you!

    •  
      Pramod3 years ago

      Yes, SAM will still fix the battery issues which crops up due to the hacktivation on iOS 3.x.x as well. For your second question, the answer is NO. Think technically, iOS 4.x.x & iOS 3.x.x have 2 totally different sets of libraries & frameworks used for app development while its compiled. Only if the developer has provided a backward compatibility to run his app on the iOS 3.x.x will it run. Its never possible the other way round or force it to work.

  •  
    Neil3 years ago

    Many thanks Pramod!!! I put my phone in DFU mode and updated with the downloaded custom 4.2.1 and so far so good. It may be a little slower but since it is my first iphone I have nothing to really compare it to and it will now run the apps I wanted to run! I thank you very much and will continue to do so every time I use my phone!!!

  •  
    Giovanni3 years ago

    Dumb question I know.
    I got an at&t 3gs, fw 4.1 jailbroken and the 06.15.00 BB.
    If I get it unlocked (paying money to people who do it for other carriers also) would I then be able to change the BB and update the OS?

    •  
      Pramod3 years ago

      Obviously you cannot downgrade your BB once its updated, may it be by paying money/may it be you yourselves doing the unlock.

  •  
    Neil3 years ago

    Very good! I do have a couple questions about that. do I use activated or unactivated and do I want extra functions or no extra functions. Thanks again for your help and advice.

    •  
      Pramod3 years ago

      Use hacktivated if you do not have the official carrier SIM to which your iPhone was actually locked to. Next, avoid the extra functions as this tends to slow down the iP3G due to its lack of RAM & hardly enough processor power.

  •  
    Neil3 years ago

    Hello,
    I am new to the iphone. A got a 3g model MB704LL from a friend that I upgraded to 4.2.1 then jail broke with redsnow and unlocked. I upgraded to the 6.15 BB when I did the unlock and used ultrasnow666 in cydia. After successfully completing that itunes was recognizing the # from the ATT sim card instead of my Tmobile sim card #. I thought I could just rejailbreak but it went into 1015 error. After looking around and researching I figured out how to downgrade from 4.2.1 to 3.1.2 and it worked! BUT there are several apps that I would like to run that require 4.whatever to run so

    now I would like to upgrade my jailbroke and unlocked 3g running 3.1.2 with 6.15.00 back to 4.1.2. every time I try to upgrade it goes into 1015 error. Can I perform the upgrade?

    Thank you for your help!!!

    •  
      Pramod3 years ago

      Use a custom IPSW for your restore as you have updated your BB to an iPad’s BB. Download one from here http://bit.ly/k1DeYH & follow the instructions mentioned in the links towards the end of this post.

  •  
    Magneto3 years ago

    well, its the end of summer and still no iPad BB downgrade :((( i am losing all hope and thinks its not doable…Musclenerd didn’t know what he was talking about it seem :/

    Anyway, if there is anyone thinking about the iPad BB, don’t do it. I did not lose GPS but the antenna strength went down and I get dropped calls all the time. Its not worth it, better sell it or try to unlock it officially but DO NOT UPGRADE TO THE IPAD BASEBAND EVER!!!!

    Yeah, I completly agree… But unfortunately I´m in Argentina, and tehre is no Apple store nor official Apple support or Warranty, so I think my only choise is to drop the phone…

      No problems.
      Have you tried a different USB cable as well? Use a known-good, working USB cable & redo the restore. It might work.
      Update: Put your iPhone into a DFU mode first & then continue with the restore. That should help.

    •  
      Pramod3 years ago

      If your absolutely sure that everything you have tried never actually worked, you might want to take it to the nearest Apple store to get it checked. Could be a possible hardware issue as well & since your do not rely on an unlock, you really shouldn’t be facing the 16xx errors.

  •  
    Julian3 years ago

    I have an iPhone 3GS Factory Unlocked. I tried to upgrade its firmware from 4.3.4 to 4.3.5 via iTunes. I don’t care about jailbrake or software unlock, so I used iTunes hoping to upgrade without any problem. But when the process was nearly finished, the phone screen turned black and there was no way to turn it on (iTunes error 1600/1601). I tried a lot of things (changing USB port, changing computer, using XP or Windows 7, using Tinyunbrella to kickout of recovery mode) but it appears to be stuck in DFU mode. A friend of mine told me to leave the phone alone until the battery is completely empty or to open the phone and disconnect the battery for 2 hours. Is that right? Do you know anyway to solve this problem? Thanks in advance.

    •  
      Pramod3 years ago

      Uninstall and reinstall the latest version of iTunes & redo the restore & also make sure that you disable any 3rd party security software that might be running at the background.

    “For the iP3G, use a custom IPSW to restore your device. Download it from here http://bit.ly/k1DeYH & restore your device using this in a Pwned DFU state. Avoid using TU.”

    I just tried this. I put the IP3G in Pwned DFU state using redsnow mac_0.9.7b6 it began extracting firmware and then gave me error 9 I have also recieved error 6 and 21 in the past trying to restore custom firmwares…. any suggestions

    Also for my Iphone 3gs I cannot see the carrier name beside the signal bar, when i put in my telus sim, it gives me one bar for about 5 – 10 secs then it says searching for a couple secs then NO SERVICE, and thats it same thing every time. I tried phoning 611 for telus to check to see if the iphone was lost or stolen…. (I just bought it off ebay) and they told me their was no way for them to check, so i tried apple and I couldnt find out how to check if it is lost or stolen from them either

    •  
      Pramod3 years ago

      Error (9) has something to do with the USB connection dropping off unexpectedly or stopping. Using a different USB dock-connector cable, trying another USB port, restoring on another computer, or eliminating conflicts from third-party security software could resolve this issue. This has nothing to do with the restores & is purely caused by your machine. Also, about the iPhone, you might want to contact that seller of yours once again.

    I have just got a new iphone 3gs and I would like to jailbreak and unlock. However i would like to unlock it to a BB that allows for GPS functionality (not 6.15.00)
    What would you suggest I do?

    •  
      Pramod3 years ago

      Do nothing. Updating to an iPad’s BB is the only way to unlock your iP3GS as of now. If you don’t want to take your chances of loosing your GPS functionality, I suggest you don’t unlock.

    Hey Pramod,
    I have two problems with separate phones, the first is a 3GS on bb 6.15 and 4.1.
    My problem with this phone is I have unlocked it with ultrasnow but i still get the no service or one bar error. I cannot call out or receive calls even if i am on one bar either. I have tried using ultrasnow on 4.2.1 4.3.1 4.3.3 and then I finally downgraded back to 4.1 at the suggestion of someone else. I have tried the carrier fix from pushfix team, I have tried allot of other things but cannot recall everything at the moment.

    The second phone i have is a 3G on bb 6.15 and 4.2.1. I had this phone up until last week running awsome. I had it unlocked and all was well until i decided i wanted to sell it and I wanted it a fresh start for whoever bought it so I decided to do the RESET thing on the phone. I waited for about three hours and it stayed on the apple logo screen, so I held power and home until it went off. I then tried turning it back on but nothing. I ended up trying to re-jailbreak it with redsnow and it went through the entire process then froze at the end of it 4 times, I also tried to restore it using custom ipsw and stock ipsw. I finally tried restoring through itunes which took about 40 minutes and then it gave me an error. It is now stuck in DFU and I dont have a clue what to do or where to start. anyhelp would be awsome

    •  
      Pramod3 years ago

      So, your unlocked, but you aren’t able to make/receive calls with the first one. No Service definitely means that your iP3GS is able to detect your SIM, but not able to access the network for a GSM signal. Are you able to see the carrier name? Looks like your iPhone’s IMEI as been blocked by your carrier because it was reported either lost/stolen by someone. You might want to check that up with your carrier first/previous owner if any.

      For the iP3G, use a custom IPSW to restore your device. Download it from here http://bit.ly/k1DeYH & restore your device using this in a Pwned DFU state. Avoid using TU.

    OMG I JUST FOUND OUT WHAT WAS THE PROBLEM!!!ALL THIS WEEKS TRYING TO FIND THE SOLUTION!!! MY SIM HAD A PIN SO I REMOVED IT ON ANOTHER PHONE AND NOW IT WORKS

    I try this ifaith program and after i save my blobs when i go create ipsw when i browse its not there! Its visible when i go direclty where i saved it but its not visible when i browse via ifaith.

    •  
      Pramod3 years ago

      Choose iFaith SHSH Files (*.iFaith) from the type of files to be listed while browsing.

  •  
    shadowneko0033 years ago

    Just for clarification:

    save SHSH blobs, then use iFaith to “Build *signed* IPSW w/blobs” or create a custom IPSW using Sn0wBreeze (“Build IPSW”) right?

    •  
      Pramod3 years ago

      No, that’s not right. Read this http://bit.ly/qIa3E7 to save your SHSH blobs using iFaith & reuse iFaith to build signed IPSWs. No Snowbreeze/Pwnage is necessary here.

    I am an Iphone 3gs 4.3.3 baseband 6.15.00 user. So i updated the baseband from 05.16.02 to 6.15.00 via redsnow and unlocked my iphone and then on itunes i pressed restore as backup, not pressed restore as a new iphone and that messed up everything! My phone was locked again, and since i cant unlock it again I tried milions of solutions still wont unlock. I read somewhere that i can mess up my unlock forever. Do you have any suggestions? I would be greatful. Thank you!

    •  
      Pramod3 years ago

      Rerun redsn0w once again, but this time make sure that you haven’t ticked any of the available options & continue.

    I have been using my unlocked iphones 3gs ( on 6.15 ipad baseband, 4.2.1 firmware ) for sometime now.
    I noticed battery drain, and did a “erase all settings and content” option.
    Unfortunately now i am stuck on the greenpoisOn logo and thats it.
    Nothing helps.
    Is there any way for me to go back to the unlocked state on 6.15 ( what i was using ). I think i should not have done a erase content option. But is the phone bricked now and cannot be restored ?

    Please advice. Thank You

  •  
    Phill3 years ago

    Before I go for the iPad baseband, I’d like to try asking the original carrier to Factory Unlock the iPhone 3GS that I got from e-bay.

    Does anyone know how I can use the IMEI number for example to find out who the phone’s original carrier was ?

    •  
      Pramod3 years ago

      Contact the dealer who sold the iPhone to you in the first place. Without proper proof/identity that the iPhone (or any phone) actually belongs to you, no carrier will reveal such confidential information (since your IMEIs are at stake with which in the wrong hands things could get real ugly). You can do the math.

  •  
    Phill3 years ago

    Good to see confirmation that someones 3GS GPS is still ok on iPad bb. Could you let us know some more details of your phone – E.g. Model (such as MC133B) and BootROM (such as 359.3.2) Thanks.

    •  
      Pramod3 years ago

      The iPad GPS loss doesn’t revolve around a specific iP3GS model. Its a hit/miss chance that’s taken when you update your BB the first time.

  •  
    Jack3 years ago

    While I agree that there’s a likelihood that it is the hardware, I won’t be able to find out by updating it because my iPhone 3G is at the top of the update ladder. If I’m incorrect, I’d sincerely and humbly love to be enlightened. iTunes (and tons of supporting evidence on the Internet) tells me that my iPhone is “up to date”. Are you saying that iPhone 3G firmware 4.2.1 now injects baseband 05.16.xx?

    •  
      Pramod3 years ago

      Oops, I missed that yours was an iP3G not an iP3GS. Please ignore my last comment. Since your on an iP3G, there’s nothing that you can do about it other that maybe try a restore again on the same which also wouldn’t help. Apple store is your last option.

  •  
    Jack3 years ago

    I have a 3G with FW 4.2.1, BB 15.05.04, and bootloader 5.09. I have the dreaded “no WiFi” issue, and I REALLY don’t want to flash my BB up to the iPad BB. I can’t fuzzyband-it because of the bootloader version, and I’m at the latest firmware, so I can’t do a total system update. I’m locked into an AT&T contract, so I could care less about unlocking. Jailbreaking would be nice, but not necessary. What I’d really love to be able to do is to re-flash the existing BB. I think that would probably fix the issue, but I’m not fining any evidence that it’s possible. It looks like a restore skips reflashing the baseband if the version is current.

    •  
      Pramod3 years ago

      Since you haven’t updated your BB also, I simply believe that this is more of an hardware issue. Get it checked at the nearest Apple store. FuzzyBands & bootloader versions are a thing of the past. If you really want a reflash, update to the latest iOS version which is on 05.16.xx. That will change your BB version, but I’m positive that this problem would exist even then.

    Hi Guys,

    I’m throwing this to you as this seems to be the most organised and sensible thread of Q&A that I’ve found online.

    I have a 3GS that I upgraded to the iPad baseband. It worked fine and I managed to get the unlock. But, I stupidly clicked to upgrade in iTunes to 4.3.5. Idiot, I know. I didn’t even realise my mistake until the ‘update’ had finished. Now I’m stuck in an infinite loop of recovery mode.

    I have tried to downgrade custom firmware 3.1.2, 3.1.3, 4.1, 4.2.1, 4.3.3 both with Sn0wbreeze and Pwnage. I’ve tried Greenpois0n, Tiny Umbrella….well, I’ve tried just about everything.

    Any help, advise or guidance would be greatly appreciated.

    Thanks

    RTM.

    •  
      Pramod3 years ago

      Tell me first, for which iOS versions do you have an SHSH blob saved via Cydia? (Atleast one that you remember of like this http://bit.ly/p07pX2.) Also, avoid using TU & utilize the edited hosts file instead for your restores.

  •

    hi all,

    I have a 3g i unluckly upgrade it firmware with 4.2.1 and it upgrade my baseband 5.15.4 now i manage to downgrade from 4.2.1 to 3.1.2 but my baseband is still 5.15.4 that is why i am unable to unlock my iphone.

    Please help me to unlock my iphone and i don’t want to up grade my baseband to ipad base band.

    My boot loader is also above 5.8

    please help me thanks in advance.

    •  
      Pramod3 years ago

      The only way that you can unlock your iP3GS now is to update your BB to an iPad’s BB instead. Once updated, you cannot downgrade your BB ever again. Read this http://bit.ly/lccwoE.

    Jeez Figure it out already! Every single firmware that the PSP/sony throws at us has been hacked or is hackable ATM. granted its not a phone and were not unlocking the psp for 50+ carriers worldwide but the success is 100% or near that. Is there just not enough people working on iphone?? BTW i mean no disrespect and cannot do what they do, to a certain extent.

    hello,
    i have downgraded a 3gs from 4.3.5 to 4.3.3, then installed cydia and ipad BB,
    then ultrasnow and got the phone unlocked,
    then i read in somewhere about SAM that helps for battery life, then i installed it,
    the GPS is working fine, Battery is seems to be good.

    i just wanted to share from my experience..

    Still no update on how to downgrade the 06.15.00 baseband ? Next time I am never going to do anything irreversible. I think the gevey sims or simcard unlock are far more safer and simpler that the software stuff.

    Less crashes, battery drains or other issues. I bought my Iphone 3Gs for GPS and after unlocking using BB 06.15.00 I lost my GPS. Since Nov 2010. I’ve been waiting anxiously and I dont see any light shedding to the iPad baseband issue.

  •  
    Julian3 years ago

    Hello,

    I have an iPhone 3GS on firmware 4.2.1 and iPad baseband 06.15.00.
    Is there any chance to get rid of the tethering process I currently need to do every time I ran out of battery or I turn off the phone? (I can only reboot the phone using redsn0w every time).

    Hope you to understand my poor English.
    Thanks in advance.
    Julian.

    •  
      Pramod3 years ago

      Yes, use Greenpois0n RC6.1 over your existing iOS 4.2.1 JB.

  •  
    Barth3 years ago

    oh sorry, my mistake. ok, since i only want my phone unlocked, im gonna have to upgrade to the ipad bb 6.15. do i need to do some “custom” firmware restore? i already have the 4.2 firmware coz itunes updated it and that’s how i got the 5.15.04 bb.

  •  
    shadowneko0033 years ago

    So you’re best recommendation for those on bb 06.15 and that want to downgrade or anything, we should wait and see what iOS 5 has to offer?

    If I ever need to restore my iphone, I was have to restore using a custom firmware since I’m on 4.3.3 with bb 06.15 right? (because the battery life sucks, and yes, I’m currently following the Battery tips)

    On another hand, the guides that you guys post here are VERY straight forward and easy to follow. Thank you!

    •  
      Pramod3 years ago

      Thanks for the thumbs up !!
      Also, if your looking forward to restore your iOS anytime soon to 4.3.3, make sure that Cydia lists that version for you like this http://bit.ly/p07pX2. if it doesn’t, use iFaith & save one for your device.

  •  
    Lee3 years, 1 month ago

    I have an iphone 3gs, I was running 4.3.3 and have 6.15.00 bb. Foolishly I tried to update my phone thinking i could just jailbreak on 4.3.5 again… not the case. I’am stuck in recovery, I have tried for 2 days to get it out using redsn0w, tinyumbrella, green poison, pwnage tool to create custom ipsw’s and restore with Itunes, I keep getting the error message my iphone isn’t eligible for the requested build, and error 1015. I have tried restoring with a stock ipsw and created custom ones with pwnage tool and no luck. I try entering DFU mode and restoring with itunes-no luck again. Again I have been looking for a solution for 2 days to no avail,

    please help :’(

    •  
      Pramod3 years ago

      Well, did Cydia save for you an SHSH blob on iOS 4.3.3 like this http://bit.ly/p07pX2. Most probably yes, so create a custom IPSW using Sn0wBreeze & use that to restore your iP3GS in a pwned DFU mode ONLY. Read this http://bit.ly/mbFORU. Error 1015 is a baseband mismatch caused simply because your trying to restore your device using the stock IPSW which you shouldn’t.

    hello.i have an iphone 3G with firmware 4.2.1 (8C148) and BB 5.15.04. Based on what i’ve read here, the only way i can unlock this phone is to upgrade to ipad bb 6.15 and then downgrade again to 5.13? Am i correct in this? I would like some help if you guys can, because im a newbie when it comes to unlocking. Thank you in advance.

    •  
      Pramod3 years, 1 month ago

      No your wrong !! There isn’t any downgrade procedure involved. Once you have updated your BB, that’s it & yes, this is the only way to get your iP3G unlocked.

    qvilorio3 years, 1 month ago

    Many Thanks Pramod, however:

    1) After wiping it will prompt me to restore from a selection of backups?
    2) If I restore my 3gs on the same 4.2.1. pressing restore from iTunes, will it restore my iPad BB also?

    •  
      Pramod3 years, 1 month ago

      1. No, it won’t. If you want to set your iPhone up as a new device, you’ll need to restore.
      2. No, it will not. Instead it will update your iOS to version 4.3.5 & ultimately kick your device into a recovery loop. No, it will not restore your iPad BB either.

      SHSH blobs are only for restoring/updating the iOS versions of your iDevices, not for the BB versions.

  •  
    qvilorio3 years, 1 month ago

    Hi Pramod,

    Have two questions for you:
    1) Can I wipe an iPhone 3G and fill the info from a backup without restoring per se, just want to do the second phase after you restore, the one that ask you would I like to use backup x?
    2) My iPhone 3GS is jailbroken via redsnow, but it is tethered jailbrake can I perform untethered jailbrake? I have 4.2.1 in it.

    Thanks,

    •  
      Pramod3 years, 1 month ago

      1. Yes, you can wipe every data that you ever had on your iP3G. In the Settings app, tap General, then scroll down to Reset and tap it. The option to Erase All Content and Settings is the one you want. It will remove any trace of personalization and all your installed apps, returning your phone to factory-fresh condition, so make sure you have a backup of the same. Be sure you’re plugged into power or that the device is fully charged before you begin.

      2. Yes, use Redsn0wRC19, but using RS after a fresh restore of your iDevice is always advised.

      With what error message did iTunes error out? Use a 4.3.3 custom IPSW created by SnowB 2.7.3 & restore to that. Make sure that you have chose the right bootrom version as well while creating the IPSW & use Redsn0w to put your device into the Pwned DFU mode.

    toketaz3 years, 1 month ago

    Pramod thanks for the quick reply but i did make a mistake on my comment. It is a 3g ph with firmware 4.1.2 with bb 5.15.04. also what i noticed was that the home button was set to “ph fav” instead of home under general dont know if that makes a diff, well am at work rite now so maybe once i get home will give it another shot, will let u know if i am able to go into dfu mode. thanks

    •  
      Pramod3 years, 1 month ago

      Again your mistaken. It should be iOS 4.2.1 that your running & not 4.1. Also, change the settings of the Home button & use Redsn0wRC18 for your jailbreak & unlock.

    •  
      Pramod3 years, 1 month ago

      All what we can do is to wait until iOS 5 becomes public & see what the jailbreak community will have in stock for us. Its too early to answer your questions right now. So as of now, stay on iOS 4.1 itself.

      Did you read this http://bit.ly/pUDssX & try out the steps I had mentioned in the post one by one? Also try this, jailbreak your device using Redsn0w with the Install Cydia option ticked & then it should reboot you back into a recovery mode. Now just boot it tethered to see if its able to get you out of the loop.

    •  
      Pramod3 years, 1 month ago

      Have you made sure that the Home & Menu buttons are working fine? Also that BB is for an iOS 4.1 & not 4.2.1. Confirm with your friend first to see if he has attempted to jailbreak the iP3GS before giving it to you because his BB is already preserved for some reason.

    i tried using redsnow to JUST BOOT Tethered Now and it is stucked at Please wait while your device is being processed “waiting for reboot” it doesn’t turn on after that. these are the versions of redsnow i used redsn0w 0.9.6rc14 and redsn0w 0.9.6rc16

    •  
      Pramod3 years, 1 month ago

      Ok. So what you need to do is first follow my pastie here to find out what all SHSH blobs you have got saved for your device on Cydia. Read this http://bit.ly/pUDssX. Though your stuck in the DFU/Recovery you’ll still be able to search for them using Tiny Umbrella. Always use Redsn0wRC18. This provides a tethered unlock up until iOS 4.3.3.

    Hi Pramod.

    I got an iphone 3gs it was AT&T but I j/b so I could use it in Mexico. but it had the ios 3. (something) and I committed the biggest mistake; updated to the:
    4.3.4 and its modem firmware 5.16.02 Needless to say. i got the “invalid SIM” up in the left corner. is there any way to unlock it? so i can use my sim again? I really have tried to unlock but i just cant figure that out. Help. please.

    •  
      Pramod3 years, 1 month ago

      iOS 4.3.4 will be a tethered JB. Meaning, each time you reboot your iPhone, you’ll need the help of your PC to boot it up back again. Also, in case you get stuck in a recovery mode, FixRec43 might not be able to kick your device out of the loop successfully. Use Redsn0wRC18′s Install iPad BB option ONLY by pointing it to iOS 4.3.3. Once its updated, confirm & then follow it up with the jailbreak using Redsn0w0.9.8b4. Read his post http://bit.ly/o4X67S.

    Hello Pramond!
    i am still on ios 4.3.2 and tried to restore with the same 4.3.2
    when i use redsnow to try rejailbreake, it stops at “rebooting”
    when i try restoring with itune using custom from snowbreaze 2.6, it gives me error 3194 and 1015 and 1600 1601.
    i really put my phone on Pwned DFU Mode by using iReb. the problem is my phone does not show up and has remained in blank state for weeks now.
    when it was working well and i try to jailbreake, it writes some things on the screen after it says rebooting.
    For now, when it says rebooting when trying to use redsnow or fixrecovery it will say rebooting and it doesn’t pass there.
    the restores gives error and i was trying to restore with the same ios 4.3.2 which i was running before the phone developed this miserable fault.
    HELP ME PLEASE.

      Before you start off with the restore of your iOS 4.3.2, look at this http://bit.ly/p07pX2 and tell me if you see iOS 4.3.2 listed as one of the iOS versions on top of Cydia’s homepage. Your iPhone is jailbroken as of now right?

    •  
      Pramod3 years, 1 month ago

      Only if you had iOS 4.3.3 up there in the list along with the others will you be able to update your iDevice to iOS 4.3.3. Now since its not there, you can only downgrade to iOS 4.1 or remain on iOS 4.2.1 & update the iPad BB alone for an unlock.

    Thanks Pramod for your answer, it seems that every time I try to restore to 4.3.3 from 4.2.1., with iPad baseband, an error comes that my iPhone 3gs is not eligible for the restore. I have tried everything imaginable, I deleted the apple.com lines in the hosts file, I restarted both devices, tried in two different computers, tried it with with a custom firewire from Pwnage tool, tried with an original FW, tried it on dfu mode, tried in normal, tried it with a different cable and no avail. Do you think the newest version of iTunes is blocking me to restore? How can I achieve this, if I upgrade from iTunes it will send me to 4.3.4, wish is no good for unlock. Thanks again for your appreciated answer,

    Hello Pramond.
    Thank you for your answers, i really appreciate them. what do you mean that
    “Your stuck on iOS 4.3.4 tethered jailbreak for now.” my phone has been blank and tell me if there is anything i can do just to use the phone again. even though it just for making calls. i am really frustrated. Remember i am on ios4.3.2 and ipadbaseband.
    thank you and Happy sunday

      I’m confused. Are you still on iOS 4.3.2 or you were on iOS 4.3.2 and you tried a restore to 4.3.3 which resulted in this situation. Did the restore go through successfully and returned an error for you?

  •  
    qvilorio3 years, 1 month ago

    Hi Pramod,

    Have a question, My 3gs is on FW 4.2.1 baseband 5.15.04, should I upgrade to 4.3.3. and then install the iPad BB or should I avoid 4.3.3 and install the iPad BB straight to 4.2.1. Thanks,

    •  
      Pramod3 years, 1 month ago

      Do you have an SHSH saved for iOS 4.3.3 by Cydia? Fire up Cydia and have a look here http://bit.ly/p07pX2. If not, stay on iOS 4.2.1 & update the iPad BB alone.

  •  
    cyman3 years, 1 month ago

    Pramod
    I am not an expert so sorry for (maybe) a trivial question. If I have SHSH saved in my cydia, could I go down from 4.1 and BB 06.15.00. As you can imagine, my major concern is 06.15.00

    •  
      Pramod3 years, 1 month ago

      If your concern is the downgrade of your BB, you need to wait for the Dev-Team to come up with a BB downgrade tool. Using the saved SHSH blobs will only downgrade your iOS & not your BB. Until then, your stuck and there is no ETA from the Dev-Team as well. :(

    Hello Pramond!
    i have carefully read your posts and comments over here, i must confess that you guys are doing a great job here.
    i followed this procedures to get out of dfu but things are just getting worse with my phone.
    i am using iphone 3gs on ios 4.3.2 and on ipad baseband and i also jailbreaked with redsnow.
    my phone is blank now and i tried fixing the phone by restoring with itune making sure that my phone is in Pwned DFU Mode by usng iReb. when i try to restore, it give error 3194, when i turn on my tinyunbrella by running tss server and unchecking “set Host to cydia on Exit, it shows error 1600.
    i also tried to use snowbreaze 2.6 to create a custom and used ireb to try restoring with itune by pressing shift+restore but i stil get the same error 1600.
    i had to remove all containing gs.apple.com and restarted my pc but i keep getting the same error. i have tried all procedures i see on the internet and my phone can’t come back again.
    finally, i tried using redsnow and just marked “just boot into tethered DFU mode and it gets stucked at rebooting device and never cross that point after 30 tries. i also used fixrecovery and it says 10seconds to reboot the device and it doesn’t reboot.
    what can i do again cos its been weeeks now.
    i really need your urgent help.
    Thank you GUYs for your help
    FOX

    •  
      Pramod3 years, 1 month ago

      Error 1600 is because you need to put your iPhone into a Pwned DFU mode first before you follow it up with a restore of the iOS. Follow this: http://bit.ly/k8MNtA.
      Error 3194 is because Cydia does not have an SHSH blob saved for your device for that iOS version to which your trying to restore to. So you need to make sure first if Cydia has an SHSh file saved for your iOS. Only then will the restore go through. Once you have found that out, you can restore to only that version and nothing else. Use TinyUmbrella to find out which versions of the iOS Cydia has in store for you. Make sure that you enable the Request SHSH from Cydia option from its Advanced menu.

    Hi Pramod again,
    Basically I wouldn’t care a lot about my “faulty” BB in case my GPS works normally (like before). Everything else works fine. Even the battery behaves OK.
    Let us approach this BB issue from the other side – Have you heard any trick to make GPS working on BB 06.15.00. If the guys (dev-team) know what is causing the problem, than they could work out the way to adjust GPS working onto “faulty” BB. Right :) Or not :((

    •  
      Pramod3 years, 1 month ago

      No, there is no workaround to get the GPS working on the iPad BB. The only way to get it back is to downgrade it to an unlockable BB like 05.13.xx. Unfortunately, all what we can do right now is to wait for Dev-Team to come up with a BB downgrade tool which will resolve this issue once and for all.

    ambersun3 years, 1 month ago

    Wolverine and Pramod you are awesome! I’m stuck right now on recovery mode loop and can’t get out! Please help me! :( I jailbroke and unlocked a 3GS with firmware 4.2.1 and 06.15.00 ipad baseband with redsn0w (windows). When I gave it to my brother he accidentally clicked on check for updates in his itunes and it did an update, but it had an error and didn’t finish all the way and now it’s in the loop. My guess is that it’s stuck on version 4.3.4 with the ipad baseband and i can’t do anything else now. tried restoring to stock firmwares and re-unlocking with redsn0w. it started jailbreaking with redsn0w and then it would show this on the iphone screen:
    Please wait….
    Please wait….
    Please wait….
    Please wait….
    Please wait….
    Please wait….
    for at least 10 minutes, then it rebooted and went into recovery mode loop. how can i jailbreak and unlock this phone?! thanks so much if you could help!

    •  
      Pramod3 years, 1 month ago

      Yes, it has infact got stuck in the recovery loop. Use iReb by iH8Sn0w to get yourself out of the loop on 4.3.3. Follow this: http://bit.ly/k8MNtA.

    hello Pramond.
    i was able to run tinyunbrella and iReb. i could restore my phone with itunes but got error 1015 when it was about to end.
    my phone has remained in UDF mode and i have tried using fixrecovery and redsnow to bypass it but its not happening.
    when i use the fixrecovery, it will write somethings on my phone and later go back to the UDF mode. while the redsnow will jailbreak it totally to the level were it will say rebooting device and when those icon finish loading for it to come up, it skips back to UDF mode. what can i do now cos i am totally confused and frustrated with my phone.
    i am running ios 4.3.2
    thank you for your assistance
    Honesty

    •  
      Pramod3 years, 1 month ago

      Run Redsn0w only with the Just Boot Tethered Now option ticked.
      The reason for the 1015 error encounter is because you need to restore using a custom IPSW & not using Apple’s stock IPSW. If Redsn0w still dint work for you, use Sn0wBreeze 2.7.3, create one & restore to that.

  •  
    Honesty3 years, 1 month ago

    hello Friend!
    i tried to restore using snowbreaze 2.7.1 but it was unable to recognize my ipsw file.
    i am running 4.3.2 firmware not 4.3.3 sorry for that error.
    my tinyunbrella was able to detect my SSHS file.
    i have the iReb, snowbreaze and my former ipsw file.
    what should i do from here?
    i previously used redsnow to jailbreak my phone and when i try it again marking “install ipadbaseband” it aborts its self on downloading….
    please what is next?

  •  
    Honesty3 years, 1 month ago

    i will do just that now. i have to download iReb right away. yes i have opened cydia after my jailbreak to 4.3.3 and i installed ultrasnow with it. will give my feedback soon. but what i don’t understand is “Make sure that you point iTunes to Cydia’s server also in your hosts file”
    i am glad you are helping me.
    thank you so much @ Pramond. let me try and give you feedback.

    •

      Make sure that inside your Hosts file C:\windows\system32\drivers\etc\hosts, you have an entry like this 74.208.10.249 gs.apple.com. This is how you point iTunes to Cydia’s server to retrieve your saved SHSH blobs.

  •  
    alan3 years, 1 month ago

    Hi Pramod yes no matter what sim I put in the phone everything looks ok carrier name and good signal it will allow me to dail the number and press the green call button it goes to the calling screen then after about one or two seconds on that screen it comes up call ended.
    I think I am going to hope and wait until I can downgrade BB.

    •  
      Pramod3 years, 1 month ago

      Are you sure that for some reason your iP3G’s IMEI isn’t blocked by its official carrier? Call up your carrier & ask them if this is the case. Because this is some issue that you’ll face even after a downgrade of the BB since there is nothing wrong with the iPhone.

  •  
    Honesty3 years, 1 month ago

    please friend!
    can anything be done? i can’t even have access to anything on the phone except to receive calls. i don’t mind loosing all my files but let my phone come back. the tinyunbrella is just saying trying proxy and nothing else happens. that means my phone will remain in “iphone disabled” forever?
    honesty.

    •  
      Pramod3 years, 1 month ago

      Have you ever jailbroken your iP3GS on iOS 4.3.3 and fired up Cydia atleast once? I’m sure you must have right? If that’s the case, then chances are that your SHSH files are already saved on Cydia’s server. Go ahead & do a custom restore of the iOS 4.3.3 using Sn0wBreeze 2.7.1 and restore to that. Make sure that you point iTunes to Cydia’s server also in your hosts file & that your device is in a Pwned DFU mode using iReb.

    @Pramod, sorry if I make some question again.
    I am one of the million people with BB 06.15.00 issue, and went mad about it. Have 3Gs, 16GB and no GPS.
    1) The FW upgrade (from 3.x.x. to 4.1) was done by a friend of mine. Did he has a chance to keep my old BB during installation, or the BB upgrade was a must in such a process?
    2) Any rumors about BB downgrade method?
    3) Do you know that any 3Gs works fine (GPS) with 06.15.00? If yes, how it is possible?
    Pal, give as even unofficial rumors about BB fix from time to time. You are following that issue much closer than we can do. Regards.

    •  
      Pramod3 years, 1 month ago

      1. Yes, he definitely had the chance to preserve the BB.
      2. Only rumors. No ETA or anything of such kind is expected for a very long time. We’ll surely let our beloved readers know if anything comes by.
      3. Yes, you can browse through these comments itself. For example here, here, here & many more all across this blog. The reason of GPS loss probability is very very very minimal but for some unlucky few, this becomes a nightmare. Its a risk that needs to be taken while upgrading to the iPad BB.

    Hello, I have an iPhone 3GS jailbroken and unlocked on BB 06.15.00 on firmware 4.3.3 and I’m just wondering with the new iOS 5 coming out soon, will I be able to upgrade from my 4.3.3 to 5 without losing jailbreak and unlock? Will it also fix the gps issue?
    Thank you

    •  
      Pramod3 years, 1 month ago

      No, you’ll definitely loose everything on both counts. The iOS 5 JB may not be even out this year & w/o that, you’ll not be able to unlock your iPad BB. It’ll not resolve any GPS issues as well. In short, it is going to make things only worse both for us & the Dev-Teams.

  •  
    Joe3 years, 1 month ago

    This ist just to inform you about my success:
    I did it according to the procedure Pramod posted below:
    Downloaded iPhone2,1_4.3.3_8J2_Restore, redsn0w_win_0.9.6rc16, kept Itunes 10.3.1.55, as already installed.
    Installed as discribed by procedure, Unlocked w/ ultrasnow 1.2.3. and it worked like a charm.
    I am now on Ipad baseband and see no major flaws (GPS working, no Accu drain).
    The only question for my understanding:
    1. Why was it necessary to download the restore IPSW, as I had 4.3.3 installed?
    2. Can I ever install original software again, if I become an official unlock. Think that ATT must follow all other providers and allow unlocking after 2 years.
    Thanks a lot, Joe

    •  
      Pramod3 years, 1 month ago

      1. Since you have an updated BB which iOS 4.3.3 doesn’t recognize, it would end your restore in a recovery loop considering it as a mismatch. Custom restores don’t touch the BB itself and thus making the restore successful.
      2. No, you cannot, unless Apple comes out with an iOS version with a BB version higher than 06.15.00. That’s quite not going to happen in the near future & you’ll loose your unlock at the same time if you ever updated to such an iOS version.

    I recently upgraded to ipad baseband with my iphone 3gs on 4.3.3 and used cydia to install ultrasnow and my iphone 3gs was working perfectly. I was setting password for my device and i tried putting my passcode again, it says wrong code.
    i tried restoring with my itunes, but it gave me an error 30194.
    i used diskaid to open to go to the library, keychain, and deleted the keychain dbs and later deleted the whole keychain folder.
    my problem became worse now that i entered my password again and it iphone says iPhone is disabled…connect to itunes.
    when i connect to itune, my itunes will request me to unlock my iphone first to be able to pair with my computer.
    i kicked the phone to udf mode and tried SHIFT + restore to restore but it fails to do so and brings out error code 30194.
    please i need your help cos this is my only phone and i don’t want to loose it. any help from you guys will be highly appreciated. thanks
    Honesty

    •  
      Pramod3 years, 1 month ago

      Error 3194 is because your trying to restore to an iOS version which Apple has stopped signing. You can restore your iOS only if you have your SHSH blobs saved for 4.3.3 on Cydia. Have you done that? Check for them using TinyUmbrella. It’ll display all the SHSH blobs if any were saved by Cydia.

    I think a restore may fix it.
    Can you suggest how can I restore iOS 4.3.3 on my iPhone? I heard that a custom firmware needed for iPhone having iPad’s BB. Please tell me the procedure and the link to download the custom firmware.

    No mesasage, it all looks as it should be with the carriers name and good signal three to four bars depending on the carrier.

    •  
      Pramod3 years, 1 month ago

      Does it behave in the same manner when you pop in a different SIM from your friend’s iPhone maybe? Probably from a different carrier? If not, you might need to call up your network customer care and get the issue sorted out. Have a look.

    after that i tried to intall 3rd party apps but the apps cannot be installed.
    my firmware is 4.3.3 as mentioned above with 7.11.01 bb. what should i do to install 3rd party apps? fyi i tried to install ultrasnow 1.2.3 throgh cydia but it can’t be done.

    •  
      Pramod3 years, 1 month ago

      You need not use Ultrasn0w because Ultrasn0w is meant only for unlocking the iPhones & not the iPads. iPads come factory unlocked right out of Apple. What you need to install is AppSync from Cydia. This will enable you to happily sync 3rd party apps with your iPhone which by default iTunes will not. Follow this guide here; http://bit.ly/pbCS8A.

    •  
      Pramod3 years, 1 month ago

      If you want to remain with the official carrier itself, then you need not unlock your iPhone or update your BB to an iPad’s BB.
      Make sure that you have uninstalled Ultrasn0w from Cydia and give it a reboot.

      Was Telestra your official carrier to which your iPhone was locked to? Yes, a restore will indeed remove your jailbreak and every data that you have on your iPhone.

    right so i ring my carrier and be all please unlock my iphone..? whats my excuse for getting it locked?

    •  
      Pramod3 years, 1 month ago

      Simple !! That you have completed your contract period. It depends on the carrier if they are willing to do it for you (meaning if Apple allows them to do it), but its definitely worth the shot.

  •  
    Graeme3 years, 1 month ago

    originally i had it on a contract it has since ran out, i haven’t tried that. but if it’s not locked why cant i use the phone?

    thx for your help pramod

    •  
      Pramod3 years, 1 month ago

      Meaning you were only able to use only that carrier’s SIM in your iPhone right? If the case is that you have completed your contract period already, you can call up your carrier (to whom it was locked to) right away & get it officially unlocked by them. Then you need not worry about any kind of unlocks in the future anymore. :D

    Graeme3 years, 1 month ago

    so my 3g is locked…?

    •

      You need to tell me that. :D
      Have you tried poppin in atleast 2 different SIM’s from 2 different carriers to see if they are getting detected by your iPhone? Did you get it on a contract? If yes, then your iPhone is factory unlocked. If not, its a locked one.

    •  
      Pramod3 years, 1 month ago

      Yes, you’ll definitely need to get your BB updated to an iPad’s BB if you want to unlock your iP3GS. Note that you’ll loose any and every warranty from Apple that you currently have on your iPhone.

    hi, i got a jailbroken iphone 3gs 4.3.3 bb 5.16.02, everything works fine eccept the GPS. i m using tomtom GPS, it just stays on poor signal. so many people mentioned they will lost their GPS on bb 6.15.00, but no one mention they lost their GPS on bb 5.16.02. does anyone lost their GPS on 3gs 4.3.3 bb 5.16.02? or evryone with 3gs 4.3.3 bb 5.16.02 their gps doesnt work?

    •  
      Pramod3 years, 1 month ago

      No. This is something specific to your iPhone itself. No user of the iP3GS/4 will ever face a GPS issue on the iOS 4.3.3 with 05.16.02 BB since its the stock BB version. Therefore I would suggest you to take it to the nearest Apple store to get your GPS issue checked. This issue may not be even caused by your iPhone !! It also could be TomTom showing you a wrong GPS signal strength.

    Any update on when the downgrade for BB 6.15.00 for iPhone 3GS is coming out? I really need my GPS back.

    By the way, I tried Sherif_Hashim’s method to flash the Baseband, indeed my phone got bricked. But I was able to unbrick it only to find the BaseBand still on 6.15.

      NO. No ETA on the iPad BB downgrade tool yet from the iPhone Dev-Team.

    I have a iPhone 4 with a bb of 4.10.01 Running 4.3.3 is their anyway I can unlock it or downgrade the bb or use the 6.15.00 iPad baseband

    •  
      Pramod3 years, 2 months ago

      No, you cannot flash your iP4′s BB with 06.15.00 simply because their BB chips are different. As far as the iP4 unlock is concerned, using a Gevey SIM Interposer is the only way you can unlock your iP4.

    Hello Folks,

    I have a strange problem and I’m baffled. My friend was given a 3GS iPhone without a SIM. No idea where it is from or what netowork it was on originall. I JB and put iPad baseband on it and used ultrasn0w to unlock it. I works fine with Irish SIM cards (3, O2, Vodafone) but not with UK ones. When a UK card is in 3G access is fine but it can’t make and receive calls.

    I’m stumped, it shows no signal either when a UK card is used.

    Any help or comments greatly appreciated , its running ios 4.3.3 and modem firware according to f0recast is 06.15.0

    •  
      Pramod3 years, 2 months ago

      UK SIM’s did always have a problem with Ultrasn0w. Have you tried keeping your 3G completely OFF to see if the issue still persists?

    I just bought iphone 3GS jailbreak and unlock version 4.1. BB 06.15.00. I can not update newer version like 4.2.1 or 4.3.3 . because always got error 3194. Pramod or anybody else know any solution to pass this issue. Thanks in advance

    •  
      Pramod3 years, 2 months ago

      You will only be able to update to 4.2.1 if you have the SHSH file saved for the same. If not, you cannot update, but you still can update to 4.3.3. You’ll still need to restore using a custom IPSW and not the stock IPSW that comes from Apple as it’ll result in Error 1015.
      For Error 3194, Goto your hosts file over here: C:\windows\system32\drivers\etc\hosts. Check your hosts file for a line like this 74.208.10.249 gs.apple.com. If its there, delete the line completely & reboot your PC. Once back, continue with the restore. You’ll have no more 3194 errors. :)

    greetings! ive recently upgraded my 3gs to 4.3.3 (jailbroken) using snowbreeze and now im planning to upgrade my bb to 6.15.00. Do i need to cook another custom fw with bb 6.15.00 for this? Can you give instructions on how to go about this, just need to upgrade bb. Thanks

    •  
      Pramod3 years, 2 months ago

      If updating the iPad BB is the only thing you want, you can go ahead and choose ONLY the Install iPad BB option from Redsn0wRC18 (http://bit.ly/lMeWpa) and continue. Make sure you point it to the 4.3.3 IPSW.

      •  
        lau3 years, 2 months ago

        which ipsw do i point it to? the stock or the one i used for jailbreaking with snowbreeze? thanks again

    hi

    just wondered if anyone has heard of or used ziphone, it says you can do advanced stuff like downgrade bootloader etc. dont know if this will help with the 06.15 bb. it appears that a lot of people who have upgraded the bb have the no signal problem, me included

    •  
      Pramod3 years, 2 months ago

      ZiPhone worked only for the iOS versions 1.1.2 or 1.1.3 with BL4.6 BL and 3.9 BL. Those early days, you really needed to update and then downgrade back the BL to get your iPhones unlocked. Apple has come very far from these bootloader versions over the years. A tool that is outdated is definitely not worth the risk of loosing your already working iPhone at hand. Especially its 4 years outdated and you really shouldn’t expect it to solve the iPad BB issues of a 2009 iPhone. If it was there, the iPhone Dev-Team would surely have let us known about it. :)

  •  
    Magneto3 years, 2 months ago

    I know Sherif has been working on the unlock and that he ended up bricking his iP3G…but this is where the story ends I guess. Its been a month and noone mentions the downgrade, it’s all about the new JB any MyGreatFest. My contract with T-Mobile ends on 27.7. and after that I would like to unjailbreak and un-unlock my 3GS but I guess that it won’t happen. My signal is very weak with the iPad BB and it drops calls all the time :((( I don’t recommend the iPad BB to 3GS users, you will regret it :(((

    so a Gophone at&t is not the same? where can i find step by step instructions & d/l links to unlock for The 3g 4.2.1, bb 05.15.04? THANKS :D

    •  
      Pramod3 years, 2 months ago

      Yes, it is an prepaid AT&T SIM. Do you get any error while connecting it to iTunes? Pop it in to see if your receiving any signal as well. Being a prepaid SIM, I’m not sure if you’ll be able to use it in your iPhone. Give it a try though.

  •  
    Tiffany3 years, 2 months ago

    as far as i know it was, but i have a go phone card in the 3g now it reads no service :(

    •  
      Pramod3 years, 2 months ago

      If you want to use a SIM card other than AT&T, you’ll definitely need to unlock your iPhone.

  •  
    Tiffany3 years, 2 months ago

    excuse me for being such a Noob. But i bought a iphone from a friend who told me it was a 3gs, from what i’ve gathered online it is only a 3g.. iOS 4.2.1, 05.15.04 i successfully jailbroke the device using redsn0w, but did not successfully unlock it. I want to use this phone with a At&t prepaid card… is this possible? can i do this without unlocking or is it neccessary? if so can you post a link to maybe some step by step instructions with download links? Do i have to RE-jailbreak or can i just unlock?? im so lost, again sorry for being a TOTAL noob :)

    •  
      Pramod3 years, 2 months ago

      Was this iP3G locked to AT&T in the first place? If so, you can go ahead and pop in your AT&T SIM and start making calls without the need for an unlock.

    Hi,

    I’m going to try the upgrade to 06.15.00 from 05.16.01 (4.3.1). Can I do this with iOS 4.3.3 IPSW or do I need to find the iOS 4.3.1 IPSW?

    Thanks!
    -Adria

    •  
      Pramod3 years, 2 months ago

      The answer is, neither of them. Follow this guide http://bit.ly/kPhfh0 which explains what needs to be done in case you need to update & jailbreak your iPhone using Redsn0wRC16.

      Also you need to understand that,
      If you check both Install Cydia & Install iPad BB options at the same time, Redsn0w crashes. So, do one at a time.
      1. Install iPad BB seperately first without choosing any other option. This will go just fine.
      2. Once you have successfully updated the iPad BB, Install Cydia along with any other desired options EXCEPT the iPad BB one (Its already installed).

  •  
    MAgneto3 years, 2 months ago

    Pramod: Do you know of any indications that there is someone ou there working on a downgrade option from the iPad BB? Its been reported in January that we will have a downgrade option soon but so far nothing. Why do you assume it will be out soon? Do you know something we dont? :)

    •  
      Pramod3 years, 2 months ago

      MuscleNerd has infact quoted recently that the downgrade is very much doable, but it seems he didn’t get enough time to spare for it. Soon after that, Sherif_Hashim (BaseBand Hacker), had released pics of his attempts to downgrade the iPad BB on his iP3G, but then ended up bricking his iPhone as well.
      After that, there is no current news regarding this topic, but it definitely looks like something is going on behind the curtains. Lets just hope it comes sooner rather than later. No ETA so far on this but we’ll keep you updated on the same.

  •  
    JP3 years, 2 months ago

    You said earlier that there is a rare chance of loosing GPS. However, every other blog i see says that you definitely loose your GPS and you face battery drainiage issues since the 3gs is now on a higher baseband hence heavier load on a lighter battery. Is this true ? I can’t seem to think of taking a chance if my GOS goes away permanently :( BTW is it definite that muscle nerd will come up with a way to downgrade ipad bb to 5.13 and that then the battery and GPS issues will be resolved ?

    JP

    •  
      Pramod3 years, 2 months ago

      Different people have their different opinions. Some may state it is definite, but that’s completely untrue.
      This is what MuscleNerd of the iPhone Dev-Team has to say about the iPad BB GPS issue:

      Unlockers have been reporting mixed results about GPS functionality at 06.15.00. Until we can track down what differentiates those who retain GPS vs. those who lose it, be conservative and assume you’ll lose GPS at 06.15.00. As we work on finding the cause (and possibly a fix), please report your personal findings in our comments section. (Update: early indications are that while 06.15.00 is capable of GPS, it will require some further hacks. But please still be conservative and assume you will lose GPS at 06.15, in case the hacks don’t work).

      Believe me, I have been unlocking iPhones for sometime now, and I haven’t yet come across a GPS functionality loss issue just yet. Neither have I ever faced a heavier load on a lighter battery problem as you have stated that may result in a faster battery discharge.
      For the BB downgrader, we do not know any ETA as to when this tool will be out. Sherif_Hashim was supposedly working on the BB downgrader, but ended up bricking his iPhone in the end as well. Its assumed to be out soon though. Once the BB is downgraded, yes your GPS functionality will be back that is if you have lost it in the first place.

    Hello to all!!!

    I’ve got a probably simple but for me important question!

    If I upgrade my iPhone3GS from 05.16.02 to iPad BB 06.15.00 I’ll probably lose my GPS functionality. Does this mean that I only won’t be able to locate myself e.g. with Google Maps or this mean that I’ll have a weaker signal strength as well??

    Thanks a lot to all answers.

    •  
      Pramod3 years, 2 months ago

      The probability of loosing your GPS is rare. You may/may not loose your GPS. But, you should expect it to not work as well at the same time if you update to the iPad BB. If in case you loose your GPS, then YES. Everything including Assissted GPS, Google Maps etc related to GPS will not function anymore.

    Hey I have an Iphone 3GS. I got it from US (currently in UK now), and it came with the AT&T sim. I was using the iphone on jailbroken firmware 3.0 for a while and then i updated it to 4.3 now the thing is somehow or the other i dont know how but the baseband is 5.16.01 and my phone wont read my vodafone sim in the UK. what exactly do i need to do to get my sim running please. ive read on many websites there are some ways but i need someone to explain all these jargon terms like shsh blobs to me plzz. HELP

    •  
      Pramod3 years, 2 months ago

      You have lost your unlock by updating your iOS to 4.3.3. You’ll need to update your 05.16.01 to an iPad’s BB (06.15.00) in order to unlock via Ultrasn0w. There is a chance of loosing your GPS functionality by upgrading to the iPad BB. This is necessary, because the current Modem FW cannot be unlocked via Ultrasn0w (Tweak used to unlock.). But, it is only a rare chance of loosing your GPS, but you should expect it as well at the same time. First thing you need to do is to get a complete backup done on your iP3GS, because in case something goes wrong, all the apps, games, contacts and everything else gets deleted. So its only a precautionary measure.
      Next use Redsn0wRC16 to continue your JB & unlock. Follow this guide http://bit.ly/jVI3cT to do so and your good to go. Make sure you have updated your BB to an iPad BB as well. :)

    Hello from a few weeks back…My syncing issue has worked itself out, but I am still having some major service issues. I have 3GS MB717LL Model on 06.15.00 and 4.3.3(8J2). I am not concerned about the GPS anymore, but I just want to be able to use my phone as a phone instead of an I touch. The phone is used and the seller is telling me I need to fix the antenna by taking the phone apart. I am not about to take this phone apart and really screw it up. ANY SUGGESTIONS!

    •  
      Pramod3 years, 2 months ago

      Don’t buy it. That’s the best suggestion, because there’s no guarantee that the iPhone will ever get repaired and be in working condition 100%. Definitely there’s somthing wrong with the BB & if I think what it really is (BB is damamged Wi-Fi, BT, Call functionality disabled), then you can never ever repair it. Just don’t buy it in the first place. :)

      •  
        Smiley3 years, 2 months ago

        I already purchased the phone. I am just screwed at this point. I am strongly considering buying an I phone 4 unlocked from the US when I travel home in a few weeks. Any thoughts?

        •  
          Pramod3 years, 2 months ago

          I suppose that is the best option right now, else you may give it to a local dealer as well and try to get it repaired by them i.e if you really think its worth the shot. Else you can hold onto it for now and wait for the iPhone 5 instead which’ll be coming up soon as well.(A much better investment than the iPhone 4 for sure.) :)

      Don’t worry about anything. Just backup your iPhone and follow the procedure mentioned in my earlier comment for a fresh JB.

  •  
    tengiday3 years, 2 months ago

    I don’t think Dev-Team will be working on this baseband downgrade. The iPhone 4′s are not unlocked yet, and iPhone 5′s are coming soon. GPS function is not as important as being unlock, so they will start working on the unlock. As you can see, this will be a cycle, and there is no time to develop the baseband downgrade. Even if the unlock will be done at that time, iPhone 3GS’s are too old to worth their effort working on the baseband downgrade.

    •  
      Pramod3 years, 2 months ago

      I agree with you there. Since the Gevey works just fine, they may have lost interest in the iPhone 4 unlock. And iOS 5 is out too and they have already started experimenting it for a jailbreak. But, sherif_hashim seems to be working on the baseband downgrade, well atleast he tried and got his 3G bricked w/o a BB. That’s hope. :)

      •  
        tengiday3 years, 2 months ago

        Actually, now I don’t bother to update to the new firmware any more. Lesson learned! As soon as this GPS issue is fixed, which I think may never happen, I will use the one of the stable previous firmwares.

    hello im new to all ov this and dont understand it lol,i have a 3g and its on 6.15.00 and 4.1. Firmware, when i try to jailbreak it it all ways goes to the itunes lock screen thingy?can you please tell me what to download to j/b it and how to do it please…..thanks ray

    •  
      Pramod3 years, 2 months ago

      This happens because you need to activate the iPhone via iTunes. Pop in your official SIM that came with your phone and connect it to iTunes and your good to go. :)

        •  
          Pramod3 years, 2 months ago

          Gr8. Glad to know it worked finally. :)
          The error is due to BB mismatch. 10xx errors occur due to a mismatch in the baseband when your trying to restore to a stock IPSW. Always use Custom cooked IPSW’s to restore if your preserving your BB. :)

          •  
            ray3 years, 2 months ago

            is there any links you can give me to jailbreak it?thanks

          •  
            Pramod3 years, 2 months ago

            You are already jailbroken on your iPhone. You need not perform anymore actions. :) If you would still like to restore to 4.2.1 for a fresh JB, follow this post here http://bit.ly/k1DeYH & download the IPSW for your device. After that, you can follow this guide as well http://bit.ly/jXG4aC to get your restore completed w/o any errors.

    Jay3 years, 2 months ago

    Hi, I have been following this thread closely since buying a used iphone 3gs. The phone was locked to Orange UK carrier and i wanted to use it on Vodafone UK. I had activated it and jailbroke using Pwnage tool but wasn’t until trying to use ultrasnow that i realised i had the unlockable bb 05.16.02 version 4.3.3. After contacting Orange i have been lucky enough for them to unlock it for me! My question is now if i jailbreak using pwnage tool again, is this likely to interfere/reverse the unlcock from the official carrier??

    •  
      Pramod3 years, 2 months ago

      Nope, neither PwnageTool nor Sn0wbreeze in anyway will interfere with your iPhone’s current unlock state at all. You can go ahead and very well jailbreak your “Factory Unlocked” iPhone 3GS. :)

      •  
        Jay3 years, 2 months ago

        Thanks Pramod, good to know! After many phone calls to Orange and £20 i was shocked that once sent a confirmation email, all i had to do was insert my Vodafone sim and sync with i tunes and it was unlocked!! So if anyone else on Orange from the UK is interested, that is a way to unlock your iphone…

        •  
          Pramod3 years, 2 months ago

          Your most welcome. :) Yep, every carrier selling locked iPhones can officially unlock it for you only if your carrier allows such a service & also only if you have completed their service terms as well. You are a lucky one. :) Also, you need not worry about any future iOS updates as well. :)

  •  
    mark3 years, 3 months ago

    did you try restore it with a different computer
    or download a previous itunes may help
    also as pramod said make sure you have the correct bootrom

    •  
      Pramod3 years, 3 months ago

      My guess is its something to do with the USB cable/ Bootrom version. But since he has confirmed the bootrom is right, my bet is on the USB cable used to follow the restore.

      •  
        Mahendra Soni3 years, 3 months ago

        Hi, thanks for your reply and thanks Marks for your suggestion.

        1. I consider the Bootrom of my iPhone 3GS to be New (fixed) because Redsn0w said the 4th and 5th digits of serial number represent the month and generally all iphone 3GS on or after 45 are having Newer Bootrom i.e. Fixed. My serial number was showing 48 as month and hence I am considering it as a New (Fixed) Bootrom.

        2. I’ve got 2 USB cables from one of my friends and charging issue is same. When iPhone is plugged in it shows Apple Logo only and after few minutes (I think after draining battery) it turns to battery low symbol and start charging. After it is a little charged, soon it turns to apple logo again and stay there. It is repeating since morning. I am surprised that even its plugged in continuously the why its can’t be charged? It gets a little power in battery and then drains while showing apple logo.

        3. In some blogs I read that restoring a custom firmware will not give error : 3194 in iTunes. But I have tried this also, all the time I try to restore iPhone 4.2.1 original or custom, iTunes gives me error : 3194. I tried everything with Host file to get rid of this error but no success.

        Is there any ways that I can restore Original / Custom 4.2.1 firmware without using iTunes? I hope if once I can restore Original firmware I can save my iPhone being a crap. I will try to use other PC also, hope it may work for me.

        •  
          Pramod3 years, 3 months ago

          Hello,

          1. Your device is New BootRom.
          2. Did you try the “Just Boot Tethered” option ? Also to which iOS version are you trying to goto? Did you update your BB as well?
          3. Restoring to 4.2.1 will not be possible unless you have saved your SHSH blobs for that iOS. Since iTunes is not signing the 4.2.1 version right now, you’ll not be able to goto that iOS version and hence the Error 3194.
          4. No, there is no way to restore your iOS w/o iTunes. You’ll always need to use iTunes to restore/update your iPhone.
          5. Do try it on another PC and let us know how it goes. It should work just fine.

          •  
            Mahendra Soni3 years, 3 months ago

            Hi,

            1. Thanks for confirmation about New BootRom

            2. Yes I tried “Just Boot Tethered”, and it shows going fine on iPhone also. After process done and rebooting, this time iPhone shows a small “Pineapple Logo” at the center of the screen but after this logo nothing happens and it remains like this only. Only Pineapple Logo for around 5 – 7 minutes and then screen flashes quickly and there is Apple Logo again.

            My iPhone was on iOS 4.2.1 and Baseband was 5.15.04. In Redsn0w I used this Original 4.2.1 firmware only which I downloaded from internet.

            While first time using Redsn0w (0.9.6rc16) I only checked “Instal Cydia” to Jailbreak only. I DID NOT do a BB upgrade (Install iPad basaband). So, still my iPhone have 5.15.04 BB.

            3. Oh, it means I have to restore latest firmware (4.3.3) from iTunes? I think it will upgrade my current baseband also which is 5.15.04 this time. Shall I try this also?

            4. Ok so I wont think anymore to restore firmware without iTunes.

            5. Yes, I am try to get another PC from friend to give it an another chance.

            Thank you so much for your help and your suggestions. I appreciate your support :)

            Always glad to help Mahendra :),

            Follow this,

            For the time being, lets get your iPhone 3GS back alive. Don’t mind about ultrsn0w/JB now. So do as I say.

            1. Download the latest 4.3.3 iOS for your iPhone 3GS from here http://bit.ly/kjLNRn.
            2. Open iTunes & whilst still making sure your iPhone is connected to your computer, Hold “Shift+(Click)Restore” button in iTunes. It’ll now pop up a browse window. Point it to the IPSW you downloaded just now from the above step and wait for it to finish.
            3. Wait for it to finish. If all goes well, you’ll be back up and running your iPhone as good as new.
            4. If you don’t have the official carrier SIM to which it was locked to, don’t worry about it now.

            Follow the steps above and let me know how it goes. Good Luck. :)

            I could successfully restored my iPhone 3GS with Official iOS. Now its details are as below:
            Device Model: MC137LL/A – iPhone3GS
            Installed Firmware Version: 4.3.3
            Installed Baseband Version: 05.16.02-6.4_M3S2

            I activated it with AT&T SIM (It never catches any network as its very old. I kept it safe since 4 years when I first bought iPhone 2G. iTunes was initially unable to Activate and showing some message that network connection error. But I restarted iTunes 3 to 4 times and re-plugged iPhone to PC and re-install AT&T SIM into phone, Amazingly it got activated with this Dead SIM and I got message in iTunes to restore my backups :))

            1. Now at this point please suggest me best possible way to get it unlocked?
            2. Is there some Custom Restore Firmware available which can Unlock it just by restoring it via iTunes? (I don’t wanna mess with Redsn0w anymore :P)
            3. If I Unlock it, will it loose official activation which I have rightnow?

            Thanks & regards

            Gr8. That’s good news. Infact the SIM isn’t dead. It still has the necessary details to activate any AT&T carrier locked iPhones. It’s always the case. What about charging? Is it fine now? Is your cable working good?

            Now the best way possible to get it unlocked is via Redsn0wRC16. Yep, its very easy and simple and I assure you it will not cause any trouble at all. Custom FW restore will not be of choice to you as your not on an iPad BB yet. So the best way is to follow this guide http://bit.ly/jVI3cT point-by-point, and you’ll be able to successfully unlock your 3GS.

            Not at all, if you unlock it, you can repeat the same procedure you followed to re-activate your iPhone once again with your AT&T SIM. Nothing will be lost. Good Luck. :)

            Hello Pramod,

            I have successfully Updated and Unlocked my iPhone 3GS 4.3.3 with iPad’s BB 6.15.00 :) Thank you so much for all your help :)

            1. Just wanted to know, how to fix GPS as I have found its not working now?
            2. Any way to increase battery life because I think its draining bit faster?

            Thanks once again for all your support :)

          •  
            Pramod3 years, 3 months ago

            Good work. Glad to know it worked. :)

            1. GPS issue is a known issue with the iPad BB. At the moment, you cannot do anything about it but to wait for a Baseband downgrader to come by from the iPhone-Dev team. No ETA on that.
            2. No specific instruction on saving your battery. Make sure to keep no background apps, push notifications, 3G services unless and otherwise only when needed.

            Once again, your welcome. :)

    Hi, I am Mahendra from India. I have bought an iPhone 3GS from a friend of USA.
    Its locked to AT&T. iOS version is 4.2.1 and Modem Baseband is 5.15.04
    I researched on internet to get some ways to unlock it. I found only one method which is via upgrading it to iPad’s baseband 6.15.00 and then unlock using Cydia.

    Just wanna know if …
    (1) Is there any available or upcoming solution to get it unlocked WITHOUT using iPad baseband? Because people says it sucks battery life and disables GPS after unlock.

    (2) If no other alternate is available except upgrading it to iPad’s baseband, then which method is best available which will less affect battery life?

    Please help.

    Thanks $ regards.

      Pramod3 years, 3 months ago

      Hello Mahendra,

      I’m sorry, but as of now the iPad BB is the only option you can use to unlock your iPhone 3GS. About battery life & GPS, sure there are problems with the iPad BB, but they are very rare. The iPhone dev-team is wroking on a BaseBand downgrader but don’t expect it to come out anytime soon. You can go ahead and unlock your iPhone 3GS by following this guide http://bit.ly/i5Whj5. You must keep in mind that you’ll void any warranty that’s on your iPhone once you update the BB, you cannot downgrade it back. Good luck. :)

      •  
        Mahendra Soni3 years, 3 months ago

        Thanks so much Pramod for your reply :)

        Since there is no alternative then i will do it.
        One more thing, I have found somewhere in this forum to use SAM to activate iPhone without official SIM. Below is the link:

        http://jaxov.com/2010/12/activate-iphone-4-3gs-3g-without-official-sim-to-fix-battery-drain-issue/

        Does it mean that I can unlock the iPhone with Subscriber Artificial Module (SAM)? If not then what is this for and is this usable for me also?

        Regards

        •  
          Pramod3 years, 3 months ago

          SAM is used only for activating your iPhone via iTunes officially. Unlocking & SAM are 2 different things. SAM is used only if incase your don’t have the official carrier SIM to which the iPhone was locked to. In case you do not have the official SIM, you can use SAM to activate only. SAM is not used for unlocking. :)

            Hi Pramod,

            I tried to JAILBREAK ONLY my iPhone 3GS 4.2.1 with Baseband 5.15.04 with Redsn0w_win_0.9.6rc16. Its went fine first time and my mobile rebooted automatically though the Cydia icon was just a white and not opening. Then I checked the option “Just boot tethered only right now” and started process at Redsn0w and this time it booted with a Pineapple icon and Cydia was having real and working icon. My iPhone was previously activate (I mean I was able to see desktop icons, use Camera, iPod and Internet via WiFi) but still I installed SAM just in case I need it in future. Now from here trouble started. After installing, Cydia said “Reboot System” and after reboot there is only Apple Logo.

            I tried to restore iPhone 4.2.1 using iTunes 10.2 but every time I have error 3194 and can’t restore it also. Tried everything including editing Host file and even deleting it from “etc” folder but nothing works.

            Please suggest what to do? I didn’t upgrade it to iPad’s baseband, only did jailbreak but it can’t come out from apple logo :(

          •  
            Mahendra Soni3 years, 3 months ago

            Update to my previous post:
            I tried to put iPhone in DFU mode and then Jailbreak again, but this time it stuck at “Installing Activation Bundle” at 75% approx. And then due to battery low it goes off and then apple logo came again and stuck there.

            Phone is also always showing Apple Logo and then it shows battery low symbol is coming. I am keeping it plugged in to charge and again it shows apple logo and then battery low symbol.

            What to do mate? I am so depressed now :(

          •  
            Pramod3 years, 3 months ago

            For your first post, make sure you have checked the right bootrom for your iPhone 3GS when it asks for it. If you do not check the right one, it causes issues. Ans do not use SAM as of yet. Install SAM only after your able to successfully JB and unlock your iPhone 3GS. Also wait for a few minutes for the entire procedure to complete. Patience is virtue here. :)

            For your next question, Are you sure the cable works just fine? You must keep your iPhone plugged in for a few hours before you start with the process, because if it happens in the middle of a JB, it may cause irreversible damage to your iPhone and render it useless. Plug in the phone for a few hours before you try it out the next time. Hopefully it helps. :)

          Mahendra Soni3 years, 3 months ago

          Hi Pramod,

          When I am using Redsn0w, its asks me if my iPhone was a newer (fixed bootrom) model. According to its serial number I found its 4th and 5th digits as 48 so it falls under newer category. So I clicked YES option there.

          And, even its been 2 hours, iPhone still stuck at Apple Logo and after few minutes it shows low batter icon and stays for few minutes, then again start showing Apple Logo. I think its charging a little and when its on apple logo, its loosing charge and then goes to low battery icon to charge it again. Due to this its unable to keep full charge. My date cable is new and working fine.

          •  
            Pramod3 years, 3 months ago

            I would suggest you to try it with a different cable because your having charging issues with your cable. So I would recommend you to get a a cable that will keep your iPhone charging whilst your restoring. Take it from any of your friend who has an iPod/iPhone because the cables are same. Make sure its able to charge your iPhone properly before you proceed. Its very important that you use a cable that can charge your iPhone properly before you proceed.

    Hi, Rob here from New Zealand, awesome site you have here, most informative ive found on the net so far. one question, when the tool is released to downgrade from Ipad BB, do you anticipate that we will be able to do restores with standard IPSWs once downgraded?

    •  
      Patrick3 years, 3 months ago

      Yes, once downgraded, you will be able to use GPS and restore stock IPSWs on your iPhone BUT do not expect the downgrade method before 2-3 months.

    •  
      Patrick3 years, 3 months ago

      You can only downgrade if you have SHSH blobs for iOS 4.1 or less. The downgrade procedure is almost similar to downgrade from iOS 4.3.3 to any other firmware. You can find the step-by-step guide here http://bit.ly/kBIP4E

    I am on a 7 month I phone adventure, but need your help. I just want my freaking phone to work. I am on firmware 06.15.00 and version 4.3.3(8J2). I am having major problems with service issues. The guy who sold it to me has gotten so fustrated that he has stopped helping me try to figure out my issues.I am also having problems getting apps to transfer from my I tunes library. This is my second attempt to get an I phone to work in the Middle East. A coworker is trying to help me, but we are getting no where. I have never had this many problems with a phone before.

    PLEASE HELP!

      What kind of problems you are experiencing in syncing your iPhone with iTunes? Can you explain a bit?

        Smiley3 years, 3 months ago

        Wolvernine,

        Sorry for just getting back to you as I do not have a good internet connection where I work most of the day. I had apps that I downloaded to my Itunes library before I had a coworker take the phone to 06.15.00. The entire reason why we took it to 06.15.00 was to try to get the actual phone to work. I have major service issues and cannot even use the phone. Atop of that, now I cannot get any apps that are in my library to sync back to my phone and vice versa. The apps that he installed that he had in his library will not to sync to my I tunes library. I am so fustrated with this phone that I just want to toss it in a lake especially since is the 2nd used I phone I have purchased in the last 7 months.

        •  
          Patrick3 years, 3 months ago

          You mean you have iPhone 3GS with iPad baseband on iOS 4.3.3. Ok fine. Now you must have installed Ultrasn0w 1.2.3 after jailbreaking your iPhone and have got the signals? Right? If not then install Ultrasn0w to unlock your iPhone.

          As far as syncing issue is concerned, i will recommend you to follow this guide http://bit.ly/dStEiq

      just a suggestion did you try put the fone in dfu mode and fresh reflash of ipad baseband and firmware
      but then after 7mths im sure you prob done it many times

      assuming its jail-broken, can’t you just dl it on your phone again instead of transferring from itune? Or maybe you can upgrade to the latest itune? just my 2 cent

    Young3 years, 3 months ago

    well i upgrade my iphone 3gs 4.3.3(8J2) bb 6.15.00 the other day. my wifi is working. GPS not sure. I tried testing the gps (with wifi turned off) with the compass and it seems to be pointing in the right direction. i also tested it with map and it was off like 20 miles. so maybe its using cell phone towers to pinpoint me? can anybody chime me in on a for sure way to test the gps?

    as for people that are debating on unlocking their 3g or 3gs to ipad bb, do it! no point in having a perfectly good phone as paper weight. im sure the code guru will get the downgrading done eventually. the question is when. im perfectly happy with my new working iphone lol

    •  
      Wolverine3 years, 3 months ago

      Thats my point. People who are still waiting for iPhone 3GS bb 05.16.01 and 05.16.02 unlock, will have to upgrade to iPad bb one day.

      Yes you can lose your GPS functionality if you will upgrade your current baseband to iPad baseband.

    mark3 years, 3 months ago

    i have a basic knowledge of using redsn0w & greenpois0n
    now i was told if i update to baseband 6.15.00 i could not update firmware by itunes anymore
    is this still the case if i update my baseband 6.15.00 and then downgrade to 5.13.04

    •  
      Wolverine3 years, 3 months ago

      Yes, you can never restore stock IPSW using iTunes if your iPhone 3GS/3G is running iPad baseband. However you can always restore custom IPSWs made with Sn0wbreeze or PwnageTool. There is no way to downgrade iPad baseband 06.15.00 to 05.13.04 for now.

    do you think is a good idea to unlock it with the baseband upgrade to 6.15
    or can i just wait to a new release
    in your experience how much does this take

    Hey Wolverine,

    look, I have a 05.15.04 3GS :< I'm avoiding to upgrade to iPad's baseband because of the GPS issue but, how much does this affect? I mean, will I be able to use geolocation powered by the operator cells at least?

    And, please, give me a advise: Should I upgrade with the risk of the GPS function loss or should I wait for 05.15.04 be supported by ultrasn0w? :/

    Thanks buddy!

    •  
      Wolverine3 years, 3 months ago

      Those who upgrade baseband from 05.15.xx to 06.15.00 usually LOSE their complete GPS functionality and those who upgrade from 05.16.xx lose GPS accuracy upto some extent. I have one iPhone 4 and one iPhone 3G. My iPhone 3G (iOS 4.2.1) have iPad bb and its GPS do not work at all. I upgraded it from 05.15.04 to 06.15.00 back in November 2010 using Redsn0w. Rest of the choice is yours! Also keep in mind that unlock for 05.15.xx and 05.16.xx will never get released. Read the conclusion in the end of post!

    •  
      Wolverine3 years, 3 months ago

      Restoring stock iOS 4.2.1 IPSW would have upgraded its baseband to 05.15.04. You can use Redsn0w 0.9.6b4 http://bit.ly/ftgE8m to hacktivate and jailbreak iOS 4.2.1 untethered on your iPhone 3G. As far as unlock is concerned, Ultrasn0w 1.2.3 can not unlock 05.15.04 baseband until you upgrade it to iPad baseband 06.15.00.

      1. You need to tell me your current baseband?
      2. Did you restored stock iOS 4.2.1 IPSW?
      3. Do you have iOS 4.0.1 SHSH blobs?
      4. You can bypass emergency call screen by jailbreaking your iPhone using Redsn0w http://bit.ly/ftgE8m (Skip step 4 as you are already on iOS 4.2.1)

    Wolverine,

    I have 3GS with ver 4.3.1 (8G4) and 05.16.02 modem firmware. I assume that baseband is the same as modem firmware. Reading your response to Gary on May 3rd, am I able to jailbreak this baseband without having to change my firmware or do I need to upgrade the baseband?

    •  
      Wolverine3 years, 4 months ago

      Jailbreak the baseband? You probably mean jailbreak this firmware? Right? You can still upgrade to iPad baseband using Redsn0w 0.9.6RC12 http://bit.ly/jkqiMl

      •  
        Al3 years, 4 months ago

        Wolverine,

        Sorry, I meant to ask that if I just want to install 3rd party apps, I would only need to jailbreak and not change my baseband. Am I right about this? I have an unlimited data plan and would like to use my iphone as a hotsopt for my ipad 2 wifi only model. Since I don’t need to unlock the baseband, I can just go ahead with a jailbreak and I’m home free. Correct?

        •  
          Wolverine3 years, 4 months ago

          Oh yeah. There is no need to upgrade to iPad baseband if you do not rely on an unlock :)

    First off I’m a newbe to all this.

    What i want to do is jailbreak my 3GS that is on iOS 4.3.2 and has a baseband 05.16.02.
    Is it necessary to unlock my phone that is currently on O2 in the UK which is fine by me, to be able to jailbreak it.

    •  
      Wolverine3 years, 4 months ago

      If you want to jailbreak or unlock, in both cases you must use Redsn0w 0.9.6RC14 http://bit.ly/f9BPDI If you need unlock, do not forget to choose “Upgrade to iPad baseband” during the jailbreak procedure.

      •  
        Gary3 years, 4 months ago

        So let me get this right I can use Redsn0w to jailbreak my 3GS and it won’t effect the baseband and it will still be locked into my service provider which is O2.

        •  
          Wolverine3 years, 4 months ago

          Yup that is the case if you do not choose “Install iPad baseband” option during the jailbreak process.

    I had the problem with the 4.2.1 recovery loop with my 3G on iPad baseband and was able to kick it out with TinyUmbrella.
    I restored to stock 4.2.1, got error 1015, jailbroke with redsn0w, kicked out of recovery with TinyUmbrella.

    After that I realized that I had not activated it (didn’t know it was a foreign phone; I purchased it from a 3rd party) so I did the whole thing over again, built a custom activated firmware with PwnageTool, and used redsnow to put me in pwned DFU mode…there was somebody earlier saying they repeatedly tried to install their custom firmware without any luck…if you are still reading, did you put it in pwned DFU mode? You can use redsn0w or iREB if you have windows (I don’t so I am not sure exactly how it works).

      First you made a huge mistake by restoring stock IPSW on your iPhone 3GS with iPad baseband. You could have lost your GPS, Wifi, baseband and whole about screen! Anyways, yes to restore a custom IPSW, you need to put your iPhone in Pwned DFU Mode (http://youtu.be/2nMovKzvuIw) using iREB (http://bit.ly/g2WlkP). This will avoid all 16xx errors. Without Pwned DFU Mode, you will never be able to restore a custom IPSW on your iPhone.

    hi wolverine i have a 3gs on 05.15.04 and ios 4.2.1. i need to get it unlocked but im not sure about going to the ipad baseband,

    how bad is the battery issue?

    i dont think losing gps is the end of the world but losing wifi would be really bad :(

    will the downgrade definatly happen, how reliable is the scene on stuff like this. also is there a rough timeframe for it? months weeks etc.

    is there any other way to unlock this?

    thanks for your help, you site is very informative

    alex3 years, 4 months ago

    ok lol cool so what about my battery % and wallpaper should i jailbreak it again or would that disable the SAM

    •  
      Wolverine3 years, 4 months ago

      If you are on iPad baseband, do not jailbreak again to avoid recovery loops. If you don’t have iPad bb, use Sn0wbreeze 2.6 to enable battery percentage and wallpaper http://bit.ly/gBOM7o

      •  
        alex3 years, 4 months ago

        weird because i jailbroke it again to do the first deactivation for the SAM and it rebooted fine…. so in other words i wont b able to get my battery% or my wallpaper since im on ipad bb huh

        •  
          Wolverine3 years, 4 months ago

          No you can get battery %age by re-jailbreaking your iPhone again with Sn0wbreeze 2.6 (Expert Mode). You need to create iOS 4.3.2 custom IPSW. If you don’t wana re-jailbreak, this guide is still applicable (not sure) but give it a try http://bit.ly/fjZeOa

    hey wolverine i have a 3g iphone jailbroken with redsnow but the baseband is stuck on 05.14. should i upgrade to the ipad baseband? and does everyone who upgrades lose their wifi capabilities? oooh and will there be a fix to 06.15 soon?

    •  
      Wolverine3 years, 4 months ago

      One day or another, you must upgrade to iPad baseband. Not everyone loses Wifi or GPS functionality but there are 50% chances. Nops, the fix ain’t coming that soon, because Dev-Team is still working on the unlock of iP4 02.10.04 and 03.10.01 bb.

        alex3 years, 4 months ago

        thanx alot for ur help wolverine u been helpful. and what about the battery drainage issues are they severe or tolerable? and so u suggest me upgrading to ipad bb anyway? thanx a million

        •  
          Wolverine3 years, 4 months ago

          There are no battery drainage issues if you use SAM http://bit.ly/i7ceCI Also upgrading to iPad bb have nothing to do with SHSH blobs. If you have iOS 4.1 or less SHSH blobs, you can save yourself from recovery loops. Many people restore stock IPSWs on iPad basebands and get into infinite recovery mode loops.

          •  
            alex3 years, 4 months ago

            OK. so SAM works for 4.2.1 correct? and thank you very much ur da best! i think ima go ahead and unlock it. :)

            Wolverine3 years, 4 months ago

            You don’t have to de-activate your iPhone with Redsn0w now as SAM already have this option. Before doing anything major, do ask me first.

    Hi

    I have a 3G which is now running OS3.1.2 and has Baseband 05.15.04 and Bootloader 5.9 (long story) It is jailbreaked using Blackra1n BUT is not unlocked obviously. And I am wondering if I can downgrade my BB to 5.13.04?

    If I can then I am assuming I can then upgrade to OS 4.0.1 and then jailbreak and unlock using Redsn0w or one of the other JB tools?

    Look forward to hearing my options.

    HELP

    Zac

    •  
      Wolverine3 years, 4 months ago

      Not possible because bootloader 5.9 (5.8BL users are still lucky) has no security flaw which can help you to downgrade your baseband. The only way to unlock is your iPhone is by upgrading to iPad baseband 06.15.00.

  •  
    devastator3 years, 4 months ago

    “Upgrading your iPhone 3GS to iOS 4.3 upgrades its baseband to 05.16.01 and restoring stock iOS 4.3.1 upgrades its baseband to 05.16.02. ”

    Does this apply to a 3Gs that is on 06.15.00 , iOS4.1 ? If I upgrade to the stock iOS4.3.1 firmware would I be on 05.16.xx ?

    •  
      Wolverine3 years, 4 months ago

      Nops! Once you are on iPad baseband, you can never EVER restore any stock IPSW.

  •  
    Ashley3 years, 4 months ago

    If I have an Iphone 3gs with 4.3.1 and bb 05.16.02, the safe bet would be to wait to make sure they release the downgrade from ipad bb 06.15.00 to 05.13.04 right? I want to unlock it and jailbreak it to run it on T-mobile but I don’t want to risk upgrading the bb to 06.15.00 and having it stuck there forever.

    •  
      Wolverine3 years, 4 months ago

      Nahh! One day or another, you must take this risk. You can still wait for the unlock though!

    Jay Jay3 years, 4 months ago

    Everyone listen.. I managed to figure out how to jailbreak, keep your unlock, and stay on your baseband with 4.3 iOS. When I first got my iPhone it was running 4.3 and I was upset that I wouldn’t be able to jailbreak it. But I figured it out I am running on 5.16 basebend jailbroken unlocked with my gps! I first downgraded to iOS 4.1 and as it was done it went back to recovery mode then I used iOS 4.2 to restore and boot it back up in 4.1 running 5.16.01 then I used limera1n to jailbreak it and it kept everything and it works ^no need to use ultraslow whatsoever. Idk how I did but I’m happy. If you have any questions please email me at esjdude@gmail.com

    i am stuck with ipad bb on a 3gs, as my gps is dead now.
    what exactly is holding the dev-team back from giving us a downgrade solution?
    do they have to wait for the next version of ios, or what is it? just asking to estimate when a working solution could arise.

    •  
      Wolverine3 years, 4 months ago

      Dev-Team is working on iPhone 4 NCK unlock method as their first priority is to unlock all iPhone 4 basebands before switching their attention to iPad baseband downgrade method.

  •  
    cwkwood3 years, 4 months ago

    So, is there any time frame on the 6.15 bb downgrade? If not, is there a way to restore iPhone 3G with 6.15 to ios 4.2.1? ITunes won’t let it as it gets the classic 1015 error. Tiny Umbrella won’t kick it out and notcom said its because there is no 3G support at this time. Any other thoughts? Thanks.

    •  
      Wolverine3 years, 4 months ago

      Yeah it is a serous issue for iPhone 3G users with iPad baseband. The only way to get out of recovery loop is downgrade back to iPhone OS 3.1.2 or 3.1.3 using a custom IPSW made with PwnageTool or Sn0wbreeze (No SHSH blobs required) and then restore iOS 4.1 custom IPSW. Remember that Apple introduced baseband check wef iOS 4.2.1 and above. Also if you’ll try to downgrade back to iOS 4.1 directly from iOS 4.2.1, you’ll get error 3194 because you need iOS 4.1 SHSH blobs for that (Even for iPhone 3G and iPod Touch 2G MB). Upgrading iPhone OS 3.1.x to iOS 4.x.x do no require SHSH blobs but jumping from iOS 4.x.x to iOS 4.y.y requires SHSH blobs. Some users in comments told that Recboot worked flawlessly to kick their iPhone 3G out of iOS 4.2.1 recovery mode loop and some reported that using Redsn0w 0.9.6rc8 worked to kick their iPhone out of recovery. I am not sure but you can always give these two methods a try!

      •  
        cwkwood3 years, 4 months ago

        So, if I were to try the Redsn0w option, how would I use it to kick out my iPhone from the recovey cycle? Thanks for your very informative reply by the way. Very helpful.

        •  
          Wolverine3 years, 4 months ago

          Just jailbreak your iPhone with Redsn0w. It should kick it out of recovery.

          •  
            cwkwood3 years, 4 months ago

            Well I gave the redsn0w option a try. The problem was, I couldn’t get it back into DFU mode for the jailbreak when it was still in the recovery loop. Whenever I would go through the DFU process, the phone would just restart until it got to a plug into iTunes screen. Just for clarity, I am talking about the screen where it shows that I need to plug it into iTunes after the iOS 4.2.1 fails to install and not the one where the phone is requesting a valid SIM. Itunes still says the phone is in recovery mode but redsn0w is looking for me to enter DFU mode. There is a difference right? Do you have any thoughts? Once again, thanks for your help and advice.

          •  
            Wolverine3 years, 4 months ago

            Make sure your iPhone is connected to your PC or Mac when you are putting it into DFU mode. Trying to put iPhone into DFU mode without connecting it with your PC or Mac usually restarts it instead of putting it into DFU mode. Just connect your iPhone to your computer and then follow this http://bit.ly/hhHHdQ video guide to put your iPhone in DFU mode.

          •  
            cwkwood3 years, 4 months ago

            I thought I would share with you my findings. First off, I tried to upgrade to 4.2.1 from 3.1.3 with 6.15bb on my 3G and course I got the 1015 error. I then tried recboot to kick it out. No luck. Then, i used redsnow to jailbreak it. I was able to get it into DFU mode from recovery. It jailbroke (went through the whole process) but when it was done and rebooted, it rebooted again in recovery mode. Very wierd. Also, i could not get the phone in recovery mode with my newer computer. It just wouldn’t work. Then I tried it on my older computer and it went in. Both computers use Win 7 but the newer is 64 bit and the older is 32 bit. All very odd experiences. Any thoughts?

          •  
            Wolverine3 years, 4 months ago

            I don’t think RecBoot can fix iOS 4.2.1 recovery mode loop. For iOS 4.2.1, you need TinyUmbrella (FixRecovery) which you can download under UPDATE#1 from here http://bit.ly/f1i6fS

            PS: The most common mistakes which people do with iPhone running iPad baseband is that they restore stock IPSWs. Once you are on iPad baseband, you can NEVER EVER restore a stock IPSW. You can always restore a custom IPSW. Restoring stock IPSW on iPhone 3GS/3G will result in infinite recovery mode loop.

          •  
            cwkwood3 years, 4 months ago

            Thanks again for your reply. I failed to mention before that I tried TU also but it wouldn’t work. As far as the custom IPSW is concerned, I am very confused about that. I tried using snow breeze to create a custom IPSW but when I tried to install it with iTunes, it gets about 3 minutes into it and quits. Of course I forget the error message. I tried it several times and still no luck. Can you explain what you would do to build a custom IPSW if you were trying to upgrade to 4.2.1 with a 6.15bb on iphone 3G and you were a PC user? Once this would be done, would I still need to somehow get it out of recovery mode loop? Thanks so much once again.

          •  
            Wolverine3 years, 4 months ago

            First, you need to tell me the error code which iTunes throws when you try to restore custom IPSW. As you are a user with iPad baseband, you can only restore custom IPSWs. To create iOS 4.2.1 custom IPSW on Windows, you can download Sn0wbreeze 2.2 R3 from here http://bit.ly/eekNuR and use this guide http://bit.ly/hasi6C. As far as recovery loop is concerned, you can bypass either by using iOS 4.1 custom IPSW or by using TinyUmbrella (RecoveryFix). If TinyUmbrella (RecoveryFix) do not work, there is a 3rd workaround as well. You need to run Redsn0w 0.9.6rc8 http://bit.ly/dRc3F4 after restoring custom firmware. In all cases, first step is to restore iOS 4.1 or iOS 4.2.1 custom firmware.

          •  
            Cwkwood3 years, 4 months ago

            Well, I tried the custom 4.2.1 IPSW with Sn0wbreeze. Everytime I tried installing it, after it would extract and “begin Restore”, it would have an unknown error and stop the install. I must have tried it ten times. I have tried everything I can think of to install 4.2.1 on a 6.15bb 3G iPhone and I just decided to downgrade back to 3.1.3 and I’ll wait for the downgrade to come out. Thanks for everything.

    •  
      Pete3 years, 4 months ago

      I was able to do this using a custom 4.2.1 firmware without the 6.15 baseband included. I used the pwnage tool and created the custom firmware unchecking the 6.15 baseband upgrade option. Do a search on youtube, that’s where I found the solution. Was able to restore to 4.2.1 without any errors.

      Actually re-reading your post, I’m not sure what firmware you’re running now so the above might not work.

      Wolverine3 years, 4 months ago

      If you are already on official carrier (In this case AT&T) then why are you bothering to upgrade your baseband now? Wait for the downgrade method first. And yes, if you have AT&T SIM, it’ll work on all BBs but there are MUCH chances that you’ll lose your GPS after upgrading to iPad baseband UNTIL MuscleNerd devise a downgrade method. So in my opinion, you should stick to 05.16.01.

        Here we don’t have the AT&T carrier and my 3GS is dead…I’m using my 3G but it sux big time…
        So my doubt was about the baseband downgrade…
        And now I see that MuscleNerd haven’t released the downgrade method yet..
        I’ll be reading and reading Jaxov updates daily and waiting until have the carrier unlock for my special papper weight…
