Unlock iPhone 4/3GS on iOS 4.3.3 Using Ultrasn0w 1.2.3 [How-To Guide]

iPhone Dev-Team has just released Ultrasn0w 1.2.3 to unlock iPhone 4 and iPhone 3GS on iOS 4.3.3. For those who don't know, Apple introduced a new ASLR security feature in iOS 4.3.x which broke Ultrasn0w 1.2 naively using 0x1000 as the main executable base address. Now that iPhone Dev-Team has fixed Ultrasn0w 1.2 on iOS 4.3.3 by releasing Ultrasn0w 1.2.3, you can use it to unlock your iPhone on iOS 4.3.3 with old baseband.

UPDATE#1: For some reason, iPhone 3GS users with iPad basebands are still not able to unlock their iPhone on iOS 4.3.3 using Ultrasn0w 1.2.3 :( If anyone have got any fix, please share in the comments section below.

    well, 3G on 6.15 with ultrasnow 1.2.8 no service or one bar. internet works, can’t make calls or receive sms. Tried everything, downgrading BB, 1.2.7 ultrasnow version, mobilesubstrate 3988 and nothing helps :(

    •  
      Patrick Gumban1 year ago

      Well, this is tricky. Normally, I’d recommend that you downgrade the BB but it seems you already got to that. I’ll look into this and I’ll let you know if I find an alternative solution. :\

      •  
        Mike1 year ago

        OK, I’d be grateful. If I’m restoring in itunes with 6.15 BBI’ll get errors 1xxx or 3145, right? I need to get to pwneddfumode and install custom restore (I’ve read somewhere). Then i need to jailbreak with normal restore ipsw from apple and install ultrasn0w?Everything started in the beginning of this summer, when 1.2.8 ultrasn0w and mobilesubstrate upgraded from cydia :(

        •  
          Patrick Gumban1 year ago

          Yes, from what I know, you will need both Apple’s official firmware and a custom one. You’ll be placing your device in Pwned DFU mode using Redsn0w, then use the custom firmware to restore via iTunes (Shift+Click / Option key). Run Redsn0w again and select official IPSW, this time select only Install Cydia.

            Hugh, I’ve downgraded ipad BB to 05.13.04 went to cydia, upgraded cydia and then I can’t install ultrasn0w, as there’s dependency with >= iOS 3 version. I installed ultrasnow from sinfuliphonerepo and still get no bars. then I queued for reinstalling mobilesusbtrate and reinstalled ultrasnow along with mobilesustrate (this time original UL from dev team). did not touch restart springboard button and powered off normaly, then on then off the on. Sim is always there without pin, so I can see when it gets signal, but still no bars :(

    My friend just sent me her iPhone 3GS, it is jailbroken but I don’t know if it was unlocked.  It was originally on the Bell Network and I have a telus sim card.  I went to telus today and got a new sim card and put it in the phone.  I tried downloading the unlocking thing from cydia but it still isn’t working…HELP please.  I am technologically challenged in the extreme :(

    •  
      Patrick2 years, 9 months ago

      Hi,

      Unfortunately, there is no unlock solution yet for your baseband, not even Redsn0w or Gevey. All we can do now is wait and see if Ultrasn0w or Gevey gets updated.

    •  
      im2f4u2 years, 9 months ago

      @alexbor

      Mine got stuck at apple logo, seemed it was tryin to install something but the bloody bar didnt move at all.. nyway later I came to realise that if ur customed iOS is tethered then the phone needs redsn0w or ibooty’s latest edition to restart, so basically after successful installation of customed iOS or whenever u need to restart the phone or u run out of battery, u will find ur self stuck at that apple logo……

      Just disconnect the device from computer, wait for 10-15 seconds, connect it back, run redsn0w’s latest version, select ‘extras’, select ‘just boot’, follow the instructions to reboot the device n phone shud reboot in about 5-10 minutes in jailbroken state :)

      P.S. try avoiding running out of battery or restarting the phone till u have untethered version of ur iOS which doesnt need any assistance in rebooting the device..

    •  
      im2f4u2 years, 9 months ago

      disconnect the phone, wait for 10-15 seconds, connect it back, run redsn0w’s latest version, select ‘extras’ then select ‘just boot’ then follow the instructions n phone shud boot in bout 5 mins :)

      fyi ur customised tethered iOS need redsn0w’s help to restart the device

      P.S. try avoiding running out f battery or restarting the phone often till u have untethered version of iOS available to install in device which doesnt need ny external software like redsn0w or ibotty to reboot the device!

    pdxflier2 years, 10 months ago

    I can’t reboot my 3GS!!!!! It is stuck on the apple screen. If i try and reboot through redsn0w it gets stuck on the pineapple screen. I tried this jailbreal with 4.3.4 iphone 3gs software instead of the recommended 4.3.3 Could that be the problem?

    IdanMalka2 years, 10 months ago

    hi, ive followd the instructions for fixing the signal bars but still after recovering, jailbreaking, installing ultrasn0w, still no fix is seen.. everything was fine 2 days ago and suddenly reception just.. died

    i have iphone 3gs 4.3.2 with 05.16.02

    plz if u have some kind of solution ill be more than happy to apply

    •  
      Jacklord2 years, 10 months ago

      @IdanMalka Hi,

      Since iOS 4.3.2 comes by default with 05.16.02 baseband for iPhone 3GS users, so there is no need to install Ultrasn0w fixer or any signal bar fixer from Cydia. This signal issue is being faced by those who have preserved their basebands for unlocking purpose. You need to hard-reset your iPhone or just reflash the iOS 4.3.2 if you have saved SHSH blobs.

      Hope that helps!

        @Jacklord um so I jailbreak with sn0wbreeze and have BB 6.15.00. I’ve never had this problem before. Ultrasn0w installs then i get no signal. I’ve tried many methods to fix it but none have worked! Its also having the same problem on ios5 i can downgrade to 5.0 or 4.3.3 from 5.0.1 since i have shsh blobs. Also its an iPhone 3gs old bootrom

        •  
          Jacklord2 years, 10 months ago

          @n3oshadow One of your option is to downgrade to iOS 4.3.3 and install latest version of Ultrasn0w. Also make sure to restore custom IPSW (Not stock) since you are on iPad baseband. If Ultrasn0w 1.2.4 do not work, install Ultrasn0w 1.2.3 via DEB file manually.

Now my battery condition is pathetic…..i have tried turning off 3g bt no difference its draining very faster than before…if i turn off cellular data then i will get a battery backup…please help me…..

    •  
      Patrick2 years, 10 months ago

      Hi,

      Try activating your phone with an official carrier SIM. If you do not have it, maybe you can borrow from a friend. It will bar the search for valid certs in iOS 4.1/4.2.1. For more information: http://bit.ly/hh6vyh

      Hope that helps!

      Patrick2 years, 10 months ago

      Hi,

    Yes im sure its 06.15.00. No,i didnt abble to see any carrier around me. the funny thing is i can copy my contact to my iphone.iphone detect my phone number.and shows me im using Maxis 10.1(malaysia carrier) but it keep shows searching and no service. i’ve install ultrasnow 1.2.4, install SAM but it still the same. By the way, i active my phone using snowbreeze since i dnt have the original provider sim card.Is is suppose to show me “Your iPhone Activated”? cuz i didnt get any notification like then during my activation.

    •  
      Pramod2 years, 11 months ago

      The activation message doesn’t really matter. Have you tried using a different carrier SIM as well? Leave SAM for now.

    Hi,i having a problem to unlock my phone. i updated my iphone 3gs from 4.3.3 to ios 5 and its stated no carrier(of course its because its locked iphone). my baseband already 06.15.00. and i jailbreak using redsnow and install ultrasnow 1.2.4. but still no coverage and shows no service and searching. i did a few times,reset connection,install and uninstall ultrasnow but it still same. how to get my line back? please help me.

    •

      Are you sure that your still on 06.15.00 BB ? Are you able to receive carrier signals from other GSM networks around you in your carrier list?

    •  
      Pramod2 years, 12 months ago

      Well, what I’m looking for is whether the same SIM is capable of supporting an iPhone’s 3G option. What about the GSM option? Have you tried switching off all you data including 3G as well?

  •  
    General Plot2 years, 12 months ago

    They are active. It’s a SIM from my wife’s phone who is able to use 3G internet on her phone with no issues.

  •  
    yophie2 years, 12 months ago

    Thanks – I went to download Ultrasn0w and discovered that Cydia got stuck on a “preparing filesystem” screen indefinitely. I think this means I need to uninstall and reinstall Cydia – how exactly?? – or fully restore to a custom IPSW and start the process over again, but I don’t know how to do that, since I’m not sure I have any saved blobs (I’m on a mac)

    •  
      Pramod2 years, 12 months ago

      Yep, restore completely to a fresh custom IPSW install of your current iOS. What versions of the iOS does Cydia list here http://bit.ly/qS5bjW ? If you see the iOS version that you want to restore to already listed here, you can continue with the custom restore. Else, there is no way that you can restore to the same unless your on an iP3G. Read this http://bit.ly/oKCpYX.

  •  
    General Plot2 years, 12 months ago

    I have an iphone 3GS on 4.3.3 with 6.15.00 baseband (it’s new bootloader) and I’ve installed ultrasn0w 1.2.4, which indeed has unlocked the carrier restriction, but 3G mobile internet doesn’t seem to be working. Oddly enough, GPS is working normally. The display does show the carrier name with a 3G next to it, but it’s not able to open anything unless I’m on wifi.

    •  
      Pramod2 years, 12 months ago

      Its an issue specific to your SIM & carrier. Make sure that 3G services / settings are activated for your number. Call up your service provider if necessary.

    Hi! but can i somehow make it work now (back to 4.3.3?) because now it shows only black screen

  •  
    yophie2 years, 12 months ago

    Uh oh I did – my phone was already jb, so I un-clicked “install Cydia” when I upgraded from 05.16.02 to 06.25.00 iPad baseband, as javox said to do in the tutorial. Unfortunately, when I rebooted my phone, Cydia had mysteriously disappeared. After that, jailbreakme.com wouldn’t allow me to re-install Cydia, so I just re-installed tethered through redsn0w, and was about to download Ultrasn0w 1.2.3 to unlock when I read this comment. Did I do something wrong?? 1) Why did Cydia disappear in the first place, and 2) should I now *not* download Ultrasn0w to complete the unlock?

    •  
      Pramod2 years, 12 months ago

      Not sure why its missing now, but you can try using Ultrasn0w & see if your able to unlock your device. If not, you would need to restore your device to a custom IPSW.

    Hi Pramod!!! I need your help
    I have iphone 4 (USA) it wasnt jailbroken and had iOS 4.3.3 4.10.01 i unlocked it with Ultrasnow and it worked only with one russian sim card but denied all others. then I made jail with rersnow and nothing, I entered cydia and it said “cydia will exit when finish” and i left it for a night in the morning I found it with aple on the screen and no reaction
    tried to make jail againg but failed, now thinking about upgrading to iOS 5 but dont know if its possible to unlock it with this firm. If u have any ideas let me know thanks

    •  
      Pramod3 years ago

      You iPhone is carrier locked & currently Ultrasn0w cannot unlock your BB as its incompatible. The only way that you can unlock your device is by using a Gevey SIM. Updating to iOS 5 would even kill the possibility of unlocking your iP4 using a Gevey. So don’t update just yet.

    No but I figured out I had to do a tethered reboot. I did it a couple of times before my phone came back on. All is good.

    •  
      Pramod3 years ago

      Not even remotely possible to do something like that unless Apple officially unlocks it for you. Contact the legit carrier to which the iP4 was locked to & request them for a permanent unlock.

    •  
      Pramod3 years ago

      You need to be on the iPad BB to get your device unlocked. Make sure that your aware of the consequences of doing so & only then proceed with the unlock.

  •  
    Frodo3 years ago

    Went through all the steps down to reboot. My phone will not come on at all. It is stuck at the apple logo. Tried a hard reset and nothing. If I plug it in to the computer and start iTunes it wants to restore it to 4.3.5. If I do that will I not be able to continue to jb or ul ? I have a 3gs which had 4.3.3 and then I jb it to 06.15 before unlocking it with cydia’s ultrasn0w 1.2.3.

      Using a Gevey SIM will only help you to unlock your iP4. Ultrasn0w doesn’t support that BB.

    Heya, I have an issue as well. I have a 3G on 4.2.1 with BB 6.15.00, new bootloader. Despite installing ultrasnow 1.2.3, I still have network issues. Issues as in service being dropped about every 2 minutes or so, and not reconnecting for about as long.

    I originally jailbroke with redsnow, and recently tried a snowbreeze install – neither solved the issue. I’ve also tried the 3G/Data Roaming toggle method to no avail. Any help would be appreciated!

    •  
      Pramod3 years, 1 month ago

      This could be more of a carrier specific issue with your iPhone. Pop in different carrier SIMs to see if it still persists. Ultrasn0w takes care of the unlock ONLY which is working great.

  •  
    Sammy3 years, 1 month ago

    Hi Pramond,

    Ok following my case: I turn back to 4.3.2 because 4.2.1 was the same issue. Device still marks “no service” given.

    Under Carriers I do see all the carriers, another SIM card shows me the same “no service”, so I recognize that antena works.

    What else can I do? Please help me Guru ;)

    Guys…it worked for me!!
    I have an iPhone 3GS 4.3.3 to which i changed from BB 5.16.02 to 6.15.00(iPad). Went to cydia after the jail-break as instructed above and followed the steps; i was not sure whether i had installed ultrasnow properly but it said that installation was done. Simply rebooted my phone with my sim-card in it and this is what i observed:
    -Network coverage bars area kept showing: searching…
    -But i was able to make and receive calls nonetheless :)
    -i think i might need to take a look at the gps now!

    Thanks

      No Service suggests that your iPhone is able to read the current SIM that’s inserted. Are you able to see the list of other carrier network that’s within your area? Also, you might want to try the same with other carrier network SIMs as well to see if the same issue still persists.

    I got to this by searching about no service with ultrasn0w, read your comments with user “iPhone” and I guarantee you it wasn’t a hardware issue, and you had them go and buy a new iPhone. I have an iPhone 4 from the US and had it working for over a year, opened up cydia today, it had a bunch of updates for me, including ultraslow, so updated it and now I get invalid sim or network not available or no service. So I doubt upgrading software will “break” my aim card slot like you suggested.

    •  
      Pramod3 years, 1 month ago

      Eh break your SIM card slot? That just made no sense to me. However, currently Ultrasn0w cannot unlock an iP4 whose BB version is above 01.59.00. So if your BB version other than 01.59.00, then only the Gevey SIM can unlock your iP4. If not, you would probably want to restore to a fresh custom iOS install for which you have a valid SHSH saved for your device already either by Cydia / TU.

    dude ..i hav an iphone 3gs model no:MC637B,i hav jailbroken but it keeps showin “No Service” sign. waitin fr reply

    •  
      Pramod3 years, 1 month ago

      Before posting in a comment, first read the list of supported & unsupported BB versions. Next, confirm if your BB belongs to the supported list or not. Only then will Ultrasn0w be able to unlock your device for that particular BB version.

      Create a custom iOS 4.1 IPSW using either Sn0wbreeze/Pwnage Tool & restore to it by pointing iTunes to Cydia’s server.

    marc3 years, 1 month ago

    hello, I legally (factory)unlocked my iphone 3GS (4.1) when it already was on 06.15. Then i tried to restore it (with hold on shift, click ipws 4.1) and i get error 1013. Then I jailbroke it with redsn0w 0.9.6.b5, only when i insert my SIM it gives searching… and after some time, no service. How can i get my service back? Before i tried to restore i worked just fine. Plz! Any suggestions?

    •  
      Pramod3 years, 1 month ago

      You need to Shift+Restore to a custom iOS 4.1 IPSW instead of using the stock version. Create one using Sn0wBreeze & then restore to the same. Read http://bit.ly/rq4MtY.

    I too am experiencing a similar problem. 3gs 433 61500. Just activated with Tmobile. I live in a major city with decent coverage however my phone only gets a signal about 30% of the time. I have never gotten internet coverage outside of wifi. Have tried the 3g off, airplane mode on/off and even scotch tape on the sim. Nothing is working. Phone used to work fine so Im pretty sure it isn’t a hardware issue. Any help would be appreciated by my iphone to save it from becoming a bunch of little iphones scattered about the sidewalk.

    •  
      Pramod3 years, 1 month ago

      Well, its the iPad BB itself that’s causing this issue. I’m pretty sure that you weren’t on 06.15.00 when your iPhone used to work fine right? Also, you cannot use the 3G / VVS features on the T-Mobile because the iPhone’s h/w itself isn’t compatible with its 3G frequencies.

  •  
    Julien3 years, 1 month ago

    I have an iphone 3g model mb635c that came to me with bb 5.14.04, i jailbroke it using – redsn0w 0.9.6b5 and put the ipad bb 6.15.00, intalled ultrasn0w 1.2.3 through cydia trieed to unlock it went from the one bar to searching, and no service, i see the carrier in the list but when i try to force it it says restricted carrier… i also installed sam and samprefs a got the sam status to wildcard… firmware is 4.2.1
    Any help would be most welcome ! :)

    Thanks

    •  
      Pramod3 years, 1 month ago

      Give it a reboot & make sure that you have switched OFF 3G & other data connectivity settings as well. Also if it still didn’t work, try a SIM from a different carrier as well to see if the issue persists.

    Thanks for the UltraSnow 1.2.3 tip. It worked to restore my signal bar strength. I just want you to know I am using 02.10.04 baseband. So it’s confirmed that this baseband is supported too.

    I have been using an unlocked IP4 with baseband 02.10.04 and IOS 4.1 direct from factory. Previously i JB using GreenPoison.

    This time, I updated from 4.1 to 4.3.3 using original firmware. IREB to solve error 1604. Must be DFU mode to restore 4.3.3 from iTunes. When error 1013 appears, run FixRecovery4.3 from TinyUmbrella website and you are done. Run iTunes again and it will prompt u to update Carrier Settings. Use JailBreakMe 3.0 to install Cydia. Only 1 signal bar will be shown with a very weak usable strength of -113. Install UltraSnow 1.2.3 and you have the full signal strenght back. Everything works beautifully except CYDIA intermittently exits.

    RedSnow method should be avoided as it is the one that caused the TOTAL SIGNAL LOST and unable to detect carrier. I have experienced that with great trauma. Even UltraSnow was unable to perform it’s job on a RedSnow JB.

    I spent 18 hours troubleshooting to successfully update my ios 4.1 to 4.3.3.
    Here is 1 minute of reading that saves you from lots of unnecessary headaches.

    Good Luck.

    •  
      Pramod3 years, 1 month ago

      Your most welcome !!
      Note to All: Do not get mislead. Ultrasn0w only fixes the single signal bar issues if you are some one who has preserved the BB on a factory unlocked iP4 ONLY. It still cannot unlock carrier locked iP4s other than the 01.59.00 BB version.

  •  
    wavecloud3 years, 1 month ago

    instead of this i can do with sn0wbreeze…that wil be easy enough for me…but should i instal 4.3.3 only?

    •  
      Pramod3 years, 1 month ago

      You have the SHSH for it saved right? Then why don’t you want to use that unless you want got to iOS 4.1. Right now ONLY iOS 4.3.3/4.1 is your only option available for a restore & if you have saved the SHSH using iFaith for iOS 4.3.3, you must use iFaith only & not Sn0wbreeze. Else your restore will fail again.

  •  
    wavecloud3 years, 1 month ago

    ok so will i need to jailbreak after using SHSH with ifaith?

    •  
      Pramod3 years, 1 month ago

      Yes, you will need to jailbreak your device right after the iFaith restore.

  •  
    wavecloud3 years, 1 month ago

    yeah i think so.Whenever i open cydia,it shows ios 4.1,4.3.5 and yes i have saved current i.e,4.3.3 SHSH.

    •  
      Pramod3 years, 1 month ago

      Then use iFaith to create an signed IPSW using this SHSH & restore to that via iTunes in a pwned DFU mode.

  •  
    wavecloud3 years, 1 month ago

    I dont think so…because i was able to make calls whenever it gets network..
    So what should i do now?reinstall 4.3.3 or downgrade to 4.1 with the same ipad bb..or anything else??

    •  
      Pramod3 years, 1 month ago

      Mhm, alrighty then. Do you have the necessary SHSH saved for your device on these iOS versions before you proceed? Also have you used iFaith yet to save your current iOS SHSH?

  •  
    wavecloud3 years, 1 month ago

    yeah it shows carrier name…there is no coverage problem,it works fine on other phone…Yes i have tried using with different carrier sim on my iphone…but the problem persists

    •  
      Pramod3 years, 1 month ago

      Well this happens when your iPhone’s IMEI is blacklisted by your carrier simply as it could have been reported either lost/stolen by its previous owner. You might want to contact the seller & ask about this because from the iPhone’s point of view (Ultrasn0w unlock), everything is working as expected.

    •  
      Pramod3 years, 1 month ago

      Are you able to see the carrier name of the SIM that you have just installed? Seems to be an issue with the carrier network in your area. Have you tried using a SIM from a different carrier as well to see if the problem persists?

    TrinityTrip3 years, 2 months ago

    So after a whole weekend of trying many, many, MANY iterations of restore, jailbreak, unlock attempts I have the following final setup:

    IP 3GS
    MC132B
    BB 06.15.00 (updated by above procedures)
    iOS 4.3.5 updated accidentally by someone who knows not so much about crApple policies and sneaky ways. (RTFTAC perhaps?)
    Oh, and no blobs at all. (Getting fun now, isn’t it.)

    Purchased and used in UK. Brought to South Africa and successfully jailbroken and unlocked previously on 3.1.3

    Jailbroken with redsn0w 6.8rc4. (4.3.5 that is.)
    Installed ultrasn0w/mobilesubstrate 1.2.3 manually (No WIFI in the wild here) :-p
    Checked it’s installed via cydia(with many connection errors)

    And I have…dum dum dum…an activated phone with no signal.

    Tried another SIM with known working data, voice, text. Tried resetting all, 3G ,Data roaming and any other combination there might be. Yes, really.

    And still no signal. *sniff*

    Am I doomed until a 4.3.5 untethered/activated/unlocked release?

    Oh, and thanks for your tireless efforts and patience in running this great knowledge database. It’s awesome people like you that enable us mortals to try it out, tear out more hair, re-read the post, have a moment of enlightenment, and go on their way without so much as a thanks.

    Yes, I am in a sarky mood. Apple should add a ‘Not responsible for panic/mood/anxiety/sociopathic/homicidal disorders as a result of using our software and not being able to get your iphone fix’ clause.

    *sigh*

    •  
      Pramod3 years, 2 months ago

      Yes. MobileSubstrate does have some unknown issues with Ultrasn0w & Cydia not working on iOS 4.3.5. You might want to actually make yourselves absolutely sure about not having SHSH blobs before you ditch your iP3GS by reading this http://bit.ly/oKCpYX. :D

    Hmm I think its hardware fault, so i m planning to buy new Software Unlocked 3GS, can you please Guide me on Which baseband i should buy it so that it can be unlocked by Ultrasn0w and also don’t show “NO SERVICE” issues?
    is there any option except iPAD Baseband? it SUCKS Big time..

    i want to use iOS 4.3.3 and later iOS 5 after its launch. so on Which baseband should i buy my new 3GS in order to successfully Unlock it on iOS 4.3.3 and Above.
    thanks

    •  
      Pramod3 years, 2 months ago

      Lol. You aren’t really expecting Apple to give you an option of the iOS of your preference while buying a brand new iP3GS now are you? As of now, using the iPadBB is the only s/w unlock available for the iP3GS & if your indeed going to buy a new one, you will receive it on iOS 4.3.5 which is still a tethered JB. Don’t expect Apple to give you preferences of iOS versions either.

  •  
    Will3 years, 2 months ago

    Hey, I have an iPhone 4 that’s on iOS 4.3.5 with a baseband of 01.59.00. I’ve read from this website (http://www.geohot.us/2011/07/unlock-iphone-4-on-ios-435-using-pwnage.html) that it Ultrasn0w was able to unlock 4.3.5, but I’ve been having trouble getting my phone unlocked! Was that site misleading or am I doing something wrong? I did jailbreak using Pwnage Tool, but I use Redsn0w for it’s tether booting purposes.

    I really need a phone and I was relying on Ultrasn0w for a lock, am I screwed because I’m on 4.3.5? Also what is the side-effects to the GEVEY SIM card?

    •  
      Pramod3 years, 2 months ago

      Well that site just copy pasted an article from RedmondPie.com by altering the title to get a better SEO. There are mixed results of Ultrasn0w not being able to unlock on iOS 4.3.5. Your best way out (by saving your unlock as well) is to downgrade back to an earlier iOS version using the SHSH blobs saved by Cydia. This is the best solution to your current situation unless you don’t want to mess the unlock up forever. Updating to iOS 4.3.5 right now is a very bad move.

    Recently jailbroke and unlocked ip3gs with redsnow and ultrasnow. Started with 4.3.3 05.16.02. Took a bit to change bb since i bought the phone used and didnt have any saved blobs. itunes always gave 3194 error code when trying to restore and never finished. Not sure why redsnow worked after several attempts but it did. Saved blobs to tiny umbrella on pc but now im switching to a new pc, how do i take my tu with me in case of future trouble requiring a restore?

    •

    •  
      Pramod3 years, 2 months ago

      No Service means that though your iPhone is able to read the SIM, its not able to grab a signal for that specific GSM carrier. Also, your iPhone is depending on the battery charge for its carrier which is really weird. I would suggest you to take it to the nearest Apple Store outlet instead & get it checked. This possibly could be an hardware issue.

  •

    Yeah i already save 4.1,4.2.1,4.3.3,4.3.4,4.3.5 on my TU. Should i proceed to restore the fw?

    •  
      Pramod3 years, 2 months ago

      Yep, your good to go with the TSS Server option enabled in TU for the restore. But make sure that you Shift+Restore to Sn0wbreeze custom IPSW in a pwned DFU mode (http://bit.ly/pioV9v) always. Do not use the stock IPSW.

    I have a fix suggestion for those who expect to get service immediately but don’t like I did at first. I have T-Mobile, and at first it still said no service and I couldn’t get it to come to at all.

    So as someone in the comments kinda mentioned (Though I don’t know what he meant by update all), you should try to re-install ultrasnow 1.2.3 from the cydia app with the sim card you’re planning to use inside of the iphone (not sure if that makes a difference) but then shut down the iphone and restart, and somehow it worked magically!

    I really had no faith that this would work, but I was pleasantly surprised! Please add an update about re-installing the ultrasnow package in cydia and restarting the iphone, that should help others!

    •  
      Pramod3 years, 2 months ago

      Brand new with iOS 3.1.3 on it? Mhm, This issue is merely because you have tried using a variety of Ultrsn0w versions. You ought to use only the repo666 hosted Ultrasn0w & nothing else.
      Use iFaith first to save your current SHSH blobs on iOS 3.1.3. Read http://bit.ly/qIa3E7.
      Next, see if you have any SHSH blobs saved for your device via Cydia (http://bit.ly/p07pX2).
      Also, you still haven’t mentioned which model of the iPhone are you having.

      Eh, what kind of Dev staff writing are you talking about? Also, what is the history of this iPhone? Please write in more detail with respect to the model & what are you trying to achieve. Looks like your IMEI is blocked by your carrier because it was reported either lost/stolen by someone. (A very good possibility.)

    Yes i have tried different Carrier Sim Cards and also tried to Switch all data Connectivity settings to OFF. but SAME Result :(

    •  
      Pramod3 years, 2 months ago

      Well, it seems like your iPhone’s IMEI is blocked by the carrier reason being someone has reported either lost/stolen. You might want to contact the dealer who sold it to you/the carrier network reps itself to fond out the issue. This is clearly not an Ultrasn0w issue because your SIM is definitely being read by your iP3GS.

    rev3 years, 2 months ago

    Hi, My Details are below:

    Apple iPhone 3GS
    iOS: 4.3.3
    Baseband: 06.15.00 (iPad Baseband)
    Jailbroken: Yes (Sn0wbreeze)
    Unlocked: Yes (Ultrasnow 1.2.3)

    Problem:
    its giving NO SERVICE Issue

    MY EFFORTS TO SOLVE PROBLEM:

    * i tried to Switch ON Airplane Mode and Switch it off few times but did not worked.
    * i turned off Cellular Data and 3G still did not worked.
    * i Restarted my Phone several times after that Signals were gone phone was just “Searching” and i got “NO SERVICE” written at the top left.
    * So i removed SIM CARD, putted it again once signals were back but still i was unable to make any call or send text or access cellular data,
    * so again i tried to remove SIM CARD and putted again. once again i got “NO SERVICE”
    * so i inserted another sim cards of other carrier to check but same “NO SERVICE”

    then i Connected my phone to the Laptop and left it after few time i saw Signals were
    back this time i was able to check my remaining balance and make call.
    after few time it got fixed automatically

    But Today it again Give “NO SERVICE”

    i tried switching Airplane Mode on & off but nothing worked. i waited 3 hours but there was not a single signal..

    MY EFFORTS TO FINDOUT WHAT IS THE THING WHICH SOLVE IT AUTOMATICALLY:

    i wanted to check that by doing which act it will get normal..and after a lot of
    efforts i found out that:
    =============================================
    Conclusion: (My Findings)
    ==========================
    1. 3GS shows signals but stopped working all the Carrier activities as soon as my phone’s battery comes down to near 70% and after few mins it gives “NO SERVICE”

    If this is the case (70% Battery left)
    ———————————
    As soon As when i Plug it in with laptop via USB or Connect it with Wall Socket for Charging > signals come back immediately & every carrier activity works perfect while
    its on charging. but if i remove the cable before charging it to at least 85% or 95% Carrier Stopped working immediately.
    and if i charge it up to 85% or more then remove the cable carrier works fine
    Until it gets discharged again to 70% or Less.

    2. if the battery discharged to 40% or below then when i put my phone on charge
    the carrier still do not work until it gets charged to at least 75%.

    Now i have no idea whats going on can you please help me?

    Yes i have also tried to Restore it using Custom firmware 4.3.3 (Snowbreeze)
    and installed latest 1.2.3 UltraSn0w version from cydia.

    Pyamod. First off i read through almost all comments. I’ve been working on this JB/Unlock for a couple weeks. So on my 3GS says 4.3 fw and ipad 06.15.00 BB.
    Cydia and Ultrasn0w 1.2.3 are installed but no Signal Bars :(
    I’m so tired of trying to unlock this phone. Cydia says my SHSH are saved 4.1, 4.3.5 located ontop of cydia home screen. I don’t know what that means but whatever.
    Everytime phone is rebooted I use Ibooty to give it life again otherwise its in recovery mode.
    I do use the TinyUmbrella, i think i have SHSH saved there as well.

    So my head is about to explode. What should i do?

    •  
      Pramod3 years, 2 months ago

      iOS 4.3 is a tethered JB. Therefore, you need to downgrade to iOS 4.1 (this is where SHSH blobs are important) if you want an untethered JB (no need to use iBooty anymore). Read this http://bit.ly/rq4MtY & follow the instructions. Make sure that you perform a backup of your iPhone first.

    :-( really sad… TinyUmbrella TSS server was running, I’ve used Redsn0wRC18 (Mac), iOS 4.3.3, and I’ve selected just install iPad BB, but the device has gone in loop/Recovery mood… :-/ Did I miss something? With redsn0w_mac_0.9.6rc16 happen exactly the same. Seems that the only working Redsn0w is redsn0w_mac_0.9.6rc18! Is there a reason?

  •  
    Claudio3 years, 2 months ago

    Hi Paramod. Today I tried the mission of jailbreaking and unlocking my iphone again… Thanks to TinyUmbrella and some resources you suggested me I managed to install the 4.3.3 iOS. As expected, beacuse my baseband is still 05.16.02, now is the network that is not working! As you explained me the problem is not something wrong with Utrasn0w, but the baseband. I tried to upgrade the baseband to the iPad one with redsn0w_mac_0.9.6rc16, but with that redsnow the process crashed! The only redsnow that seems to work correctly is redsn0w_mac_0.9.8b4, but it has no option about baseband updating. How could I do? The ssh blobs I see on Cydia are from 3.1 to 4.3.5. Tell what other information would you need…
    Thanks a lot!

    •  
      Pramod3 years, 2 months ago

      Use Redsn0wRC18 & make sure that you tick only the Install iPad BB option. If you tick both Cydia & the iPad BB option at the same time, RS will crash.

    This is my first time attempting to jailbreak and unlock my phone. I have an AT&T iPhone 3GS with iOS 4.3.2. I used jailbreakme.com to jailbreak the phone and installed ultraSn0w 1.2.3 within Cydia. However I missed the note about not installing it on Baseband a phone with 15.16.02 and now I have a phone says “No Service”. I tried restoring using iTunes (10.4) from my backup that I made before attempting all of this and Cydia was still there. It took 2 hrs to restore – but in the end it seems I am not able to go back to my original version of iOS (unjailbroken). What can I do? I would prefer an unlocked phone – but failing that I really would like to go back to pre-jailbreaking so that I can use my phone. Thanks for any suggestions.

      You cannot restore back to a stock IPSW unless you have saved your SHSH blob via Cydia for that iOS version like this http://bit.ly/p07pX2. But you follow this.
      Use iFaith to save your current SHSH blob http://bit.ly/qIa3E7 & then use it to create a signed IPSW to restore to. In that way, you will be back onto iOS 4.3.2.

    it doesn’t help, now iTunes shows 14 error, says that cant restore. Maybe i created wrong IPSW, what if i will create not 4.1 but 4.3 do u think il’ll help?

    •  
      Pramod3 years, 2 months ago

      Error 14 suggests of a bad USB cable/USB dock. Try performing the same restore procedure on a different machine as well to see if it resolves your issue.

    Hi pramod I heed your help pleaseeeee)))))
    I had 4.3.5 then I found saved SHSH in Cydia’s homepage and u suggested to use SnowBreeze.
    I creaed IPSW 4.1
    Entered DFU mode
    Shift + restoe via iTunes and it gave an error 1602
    iphone entered recovery mode and…. i cant get out of it)))) I used TinyUmb, fixrecovery 43 and nothing helps, im still in recovery mode, can u help me?

    •  
      Pramod3 years, 2 months ago

      Well, a simple DFU mode isn’t enough for the restore to occur. You need to put your iPhone into a Pwned DFU mode instead & the restore. Read this http://bit.ly/pioV9v.

    Hi, My Details are below:

    Apple iPhone 3GS
    iOS: 4.3.3
    Baseband: 06.15.00 (iPad Baseband)
    Jailbroken: Yes (Sn0wbreeze)
    Unlocked: Yes (Ultrasnow 1.2.3)

    Problem:
    My Phone was working fine no issues.

    few days ago i made a call and after that Signal bars were FULL but i was unable to make any Call or Send any Text or even Cellular Data was also not working..

    so i tried to Switch ON Airplane Mode and Switch it off few times but did not worked.

    i turned off Cellular Data and 3G still did not worked.

    i Restarted my Phone several times after that Signals were gone phone was just “Searching” and i got “NO SERVICE” written at the top left.

    So i removed SIM CARD, putted it again once signals were back but still i was unable to make any call or send text or access cellular data,

    so again i tried to remove SIM CARD and putted again. once again i got “NO SERVICE”

    then i Connected my phone to the wifi+Laptop and left it after few time i saw Signals were back this time i was able to check my remaining balance but still was unable to call.

    so i restarted my phone and got again “NO SERVICE”
    ============
    but after few time it got fixed automatically
    ============

    But Today it again Give “NO SERVICE”

    i tried switching Airplane Mode on & off but nothing worked. i waited 3 hours but there was not a single signal..
    so i wanted to check that by doing which act it will get normal..

    so first of all i tried to Connect my Phone with my laptop via USB
    and Guess what as soon as i plugged it in SIGNALS were BACK
    =============================================

    so i unplugged the cable immediately and again switched Airplane Mode of & on and signals were coming but i was unable to make any call or send text or check remaining balance and after few mins it gives again “NO SERVICE”

    so again i Plugged it in with my laptop & switched Airplane Mode off & On this time i kept it connected on laptop and tried to use it at this point i was able to call text and check remaining balance and signals were full

    but when i unplugged it from laptop and switched airplane mode off and on
    signals were again coming but again i was unable make call txt or check remaining balance and it again give “NO SERVICE” after few mins
    ==========================
    Conclusion: (My Findings)
    ==========================
    1. When it gives “NO SERVICE” Just Plug it in with laptop via USB signals will come back immediately and you will be able to text, call etc

    2. As soon as you will unplug it from laptop u will be unable to text call or check remaining balance or in simple u will be unable to perform any action related to network. and after few mins it will again give “NO SERVICE”

    ================
    Still we have to find:
    ================
    That few days ago it was fixed automatically i was able to use it without connecting to laptop without any problem so which thing it was, which fixed this issue?
    =================

    Now i have no idea whats going on can you please help me?

    •  
      Pramod3 years, 2 months ago

      Well, looks like your unlock is going wacky. I would suggest you to perform a clean fresh restore of your iOS on 4.3.3 & unlock it once again using Ultrasn0w. It should work just fine then provided you verify first if its behaving in the same manner with other carrier SIMs as well.

  •  
    Will3 years, 2 months ago

    Hi,

    I followed these exact procedures from your website:
    http://jaxov.com/2011/05/how-to-unlock-iphone-3gs-baseband-05-16-01-05-16-02-on-ios-4-3-3/

    Download iTunes 10.2.2 for Windows or Mac OS X
    Download Redsn0w 0.9.6RC16 for Windows or Mac OS X
    Download stock iOS 4.3.3 IPSW for iPhone 3GS

    however my Wi-Fi button is grayed out; although I can set the Wi-Fi ON, I don’t see any available network. How can fix this?

    – Can I proceed with the unlocking procedures outlined above without a Wi-Fi or 3G data connection? I am using a Mac.

    Thanks

    •  
      Pramod3 years, 2 months ago

      Yes, you can very well continue with the manual installation of Ultrasn0w offline & look into your Wi-Fi issue later on. Read this http://bit.ly/iud3Yu.

    help me please

    •  
      Pramod3 years, 2 months ago

      Its a DFU mode & do you have the SHSH blobs saved for iOS 4.3.3 on Cydia? Did you have it listed like this http://bit.ly/p07pX2?

  •  
    Bryce Dechert3 years, 2 months ago

    Wow…. almost 14 hours later and FINALLY my iPhone 3gs is unlocked :D :D :D :D. Thanks bro!

    Details: I started with a locked iPhone 3GS running iOS 4.3.5 my friend gave to me. Yes, this method will work with the latest update. Luckily he had jailbroken the phone before so there was a SHSH from 4.1 in Cydia. Created custom ispw using snowbreeze, iReb to put in DFU mode, then tinyumbrella restore via itunes. The rest is in this guide.

  •  
    Keisy3 years, 2 months ago

    thank u))) do u have any link how to do it??

    Hi Pramod! U wont believe it but now i have SHSH 4.1 4.3.4. 4.3.5 in my cydia’s homepage!! maybe it can allow me somehow downgrade my iOS???

    •  
      Pramod3 years, 2 months ago

      Yep, that’s right. You can now downgrade to iOS 4.1 to enjoy an untethered JB.

    •  
      Pramod3 years, 2 months ago

      In that case, drop the idea of using Sn0wBreeze & download one of the custom IPSWs created by PwnageTool instead & restore to that. It should then work just fine w/o giving you any errors. Download the iOS 4.3.3 IPSW from here & try the restore once again.

  •  
    Claudio3 years, 2 months ago

    Hi Pramod. Unfortunately… no I’m not on 4.3.3 right now. The last successful jailbreak I did was to 4.3.3. After that I tried to restore upgrading the BB, but this drove the iphone to be stuck again… Why? Don’t konw! I used redsn0w_mac_0.9.6rc16 and I selected just iPad BB and the process crashed in the middle.
    I didn’t save the SHSH and then I don’t know what is the best thing to do now. My idea is upgrade to 4.3.4 and upgrade the BB in the same process. To do so, tell me if I’m wrong, I can use just redsn0w_mac_0.9.6rc16 and not redsn0w_mac_0.9.8b4. Would be this restore untethered?
    Obviously this time I wait and hope in your instruction before moving again!
    Thank you really really much!!!

    •  
      Pramod3 years, 2 months ago

      iOS 4.3.4 is always a tethered JB. So you need to use Redsn0w0.9.8b4 simply because its always good to use the latest version always. But you need to keep in mind that even the latest Redsn0w does have only a tethered JB & not an untethered one. Also , its weird to see Redsn0w crashing on a Mac. So before you try anything else, read this http://bit.ly/pUDssX & let me know if your able to find any SHSH blobs.

  •  
    Keisy3 years, 2 months ago

    there is now iOS versions on the Cydia’s homepage at all, even my 4.3.5

    •  
      Pramod3 years, 2 months ago

      Then unfortunately, your stuck at iOS 4.3.5 with a tethered JB. You might have to wait until the Dev-Team updates Ultrasn0w for iOS 4.3.5 as well. :(

  •  
    Jas3 years, 2 months ago

    hi, i got a iphone 3gs 4.3.3 firmware 05.16.02, as per your guide i chagned the baseband to 06.15 and installed cydia as well…now when i am going to cydia..it keeps on saying Preparing Filesystem (Cydia will exit when complete.) and its showing processing but its there from last half hour..and nothings happening..i have rebooted the device and i have also try and go to redsnow 09.6rc and reinstalled the cydia again…but same thing…the phone is fine its just that when i am goin in cydia its shwoing the same thing whenever im in cydia and i cant do anything..please help

    •  
      Pramod3 years, 2 months ago

      Looks like Cydia might need a re-installation. (Esp. when you have installed it twice.) Use iFaith & save your SHSH if you haven’t saved it yet on Cydia. Read this http://bit.ly/qIa3E7.
      After that, restore to the signed IPSW created by iFaith and then re-jailbreak using Redsn0wRC18. Everything should be working just fine now.

  •  
    Keisy3 years, 2 months ago

    not exactly, when i tried to download Ultrasnow adding repo666.ultrasn0w.com and it began to download but at the end gave me an error that its an older version and i cant use it, something like this so i couldnt find ultrasnow 123, if i tried to download some theme it was installed, but Sn0w – no. and cydia’s homepage doesnt show me any iOS. and now iphone trlls “no service”. i was told that now i have nothing to do but wait when there will appear unlock for this version((((

    •  
      Pramod3 years, 2 months ago

      Yes. That’s absolutely right. As of now, MobileSubstrate & Ultrasn0w 1.2.3 needs an update to work on any higher version other than iOS 4.3.3. That’s exactly why I had asked you to see what iOS versions do you see on top of Cydia’s homepage in my last comment. You haven’t responded to it yet.

  •  
    Keisy3 years, 2 months ago

    Yes i JB it to 4.3.5 (acctually i tried ti 4.3.4 dont know why i got 5 now) and bb 06.15.00 and this SHSH i saved, tried to unlock with UltraSn0w but failed((( i heard that there is a paid method to unlock it but not sure that its true) thanks

    •  
      Pramod3 years, 2 months ago

      Nope, the paid methods that you see online are all fakes. You downloaded Ultrasn0w using Cydia on your tethered 4.3.5 JB right? Do you by any chance see any other iOS versions listed on top of Cydia’s homepage just like this http://bit.ly/p07pX2 ? I’m trying to get your iPhone onto an untethered JB rather than a tethered one. Also Ultrasn0w does work, but tell me how does it fail since your already on an unlock supported BB.

  •  
    Keisy3 years, 2 months ago

    Pramod thank u so much for help, u r wonderfull!!!
    now i have 3gs iOS 4.3.5 bb 06.15.00, do u think i can unlock it now, can u advise me (because im afraid that i can spoil something again)and now i used TinyUmb and saved my SHSH)))

    •  
      Pramod3 years, 2 months ago

      Have you jailbroken your iP3GS yet? Also which SHSH blobs have you got it saved for your iDevice?

  •  
    Claudio3 years, 2 months ago

    Here Im again! Sorry for the confusion I created but the point is that I likely did a mess :-( Chronologically here is the situation: I cannot reset my iPhone 3GS because it is originally french and need the original SIM card Im not sure I could have borrowed from the friend who sold it. The first time I have jailbroken it to a 4.1 version if I remember. 4.1 should be also the original version. Anyway, then was working, but afterward it got stuck because of an update I accidentally launched from iTunes. Then I jailbroken it again to version 4.2.1 but the network was not working. I tried to jailbroken it again to an higher version (the one I told you about: iOS 4.3.3, baseband 05.16.02). But network was not working yet. I understood the way to enable it was Ultrasn0w. I tried, but it did not work. So I ended up to follow your website guide that seemed to exactly mathch with my case: redsn0w_mac_0.9.6rc16, again with OS 4.3.3 and trying to select iPad baseband. The attempt did not succeed and now I cannot jailbreak it at all. I just at this point realized the reason is that I did not save the shsh blob… Is there a way I can finally have my iPhone working?
    I try to guess: Im fucked up and I can only upgrade to version 4.3.4 with untethered jailbreak.

    •  
      Pramod3 years, 2 months ago

      All this is because of the first update you did from 4.1 to 4.2.1. You should have never updated your iOS in the first place especially from iTunes. This updated your Modem FW as well which has now rendered your unlock useless. It is not Ultrasn0w that was causing this issue but your BB versions. All these BBs aren’t Ultrasn0w supported & that’s the reason why it never worked in the first place. Why din’t the iPad BB update work? If your on iOS 4.3.3 right now, use iFaith to save your iOS 4.3.3 SHSH blob atleast. Follow this http://bit.ly/qIa3E7 & save it before you do another update.

  •  
    Keisy3 years, 2 months ago

    cydia now is OK, thank u so much u r really genious!!!!
    but then i tried to install iPad BB and went to recovery mode, what does it mean, is it all so bad againg????

    •  
      Pramod3 years, 2 months ago

      It is not the Recovery Mode all over again. As I had mentioned earlier, your having a tethered JB on iOS 4.3.4. So you need to repeat the steps every time you reboot the device. So run Redsn0w’s Just Boot Tethered Now option again.

  •  
    Keisy3 years, 2 months ago

    so finaly i managed to install cydia with redsn0w but it doesnt work, when i open it it just blink on the screen and nothing happens, even after making “Just boot tethered right now.” maybe i did somethinh wrong again????(( and is it possible to unlock it somehow now?)))

    •  
      Pramod3 years, 2 months ago

      You really need to use Just Boot Tethered Now option every time you reboot. Switch OFF your iPhone, put it back in DFU and run the tethered JB once again.
      To unlock, you need to update your BB to an iPad’s BB. Only then will you be able to unlock it. Use RSrc18, point it to iOS 4.3.3 and on the options page, choose only Install iPad BB option & continue.

  •  
    Keisy3 years, 2 months ago

    yes the size is OK, my iphose is 3gs with iOS 4.3.4 and bb 05.16.02 mayby the problem is because of firmware i had nearly given up hopes of making my phone work, im about to cry(((((

    •  
      Pramod3 years, 2 months ago

      Should definitely work then. Your pointing it to the iOS 4.3.4 IPSW right? There is no way Redsn0w is failing. Its your IPSW that’s causing this issue.

  •  
    Keisy3 years, 2 months ago

    yes im using this redsnow, how can i make sure about IPSW??
    thxs

    •  
      Pramod3 years, 2 months ago

      You need to check the size of your IPSW. It should read 420MB within its Properties. If not, your download is broken & so you might want to re-download the IPSW once again.

  •  
    Keisy3 years, 2 months ago

    •

      Are you using Redsn0w 0.9.8b3 ? Download it from here http://bit.ly/rqYb8u & also make sure that your IPSW was successfully downloaded.

    •  
      Pramod3 years, 2 months ago

      Do you have an SHSH blob saved for your iDevice on Cydia for any iOS version? Have you ever saved any blobs using TinyUmbrella? Use TinyUmbrella to find out which versions of the iOS SHSH Cydia has in store for you. Make sure that you enable the Request SHSH from Cydia option from its Advanced menu. And if you don’t have any, your stuck with the only option to update to iOS 4.3.4 with a tethered jailbreak.

  •  
    Claudio3 years, 2 months ago

    Thanks for your answer. I had reached out to install OS 4.3.3 with redsn0w_mac_0.9.8b4 after trying with previous versions of redsn0w/PwnageTool/GreePoison + previous version of the OS. I made so many trials because I couldn’t check baseband, firmware and so on, since I got the device already stuck from my french friend who tried without success to jailbreak it.
    As I wrote in my previous comment now the jailbreak end up with the screan stuck on Apple logo and this happens with every combination redsn0w and iOS I tried! Even with the one the last time succeed (redsn0w_mac_0.9.8b4 + OS 4.3.3)!
    I didn’t save the SHSH anywhere because I didn’t know about it… Now I don’t really know what to do! :-/ I can’t reset my iPhone at all!

    •  
      Pramod3 years, 2 months ago

      I’m really confused right now. Lets go step-by-step. What was your initial iOS version & Modem FW (before everything happened) & seems like it was jailbroken since you rely on an unlock as well ? What restore did you try just now which brought you to the recovery loop? I’m sure that its a 10xx error caused during the restore. Forget about Redsn0w.

  •  
    Claudio3 years, 2 months ago

    Hi! Compliments for the website, it offer a great number of helpful posts!! I bought a french iPhone from a friend of mine and I’m trying to reset, jailbreak and unlock it. I managed to install the OS 4.3.3 with redsn0w_mac_0.9.8b4 after several other unsuccessful combinations. The next necessary stpep of unlocking it using Ultrasn0w didn’t reach out. Thanks to your guidlines I understood it should be due just to the baseband, in fact it is: 05.16.02. Then I followed the most appropriate guide I found: http://jaxov.com/2011/05/how-to-unlock-iphone-3gs-baseband-05-16-01-05-16-02-on-ios-4-3-3/
    Since redsn0w_mac_0.9.8b4 does not provide the option of installing iPad baseband, I downloaded redsn0w_mac_0.9.6rc16, the same used in the tutorial. Unfortunately after many trials the process didn’t succeed! :-( Most of the time the device stuck on the booting logo!
    What do you suggest me? Try to install a previous OS or is there another way to install iPad baseband??
    My firmware verision is 4.1 and the model MC133NF
    Thank you very much!!

    •  
      Pramod3 years, 2 months ago

      Well, do you have Cydia installed already? Also, have you checked to which bootrom version does your iP3GS belong to using iDetector from iH8Sn0w? Also, do you have the SHSH saved for iOS 4.3.3 when you fire up Cydia on the top just like this http://bit.ly/p07pX2 ?
      Also I dint understand what did you mean by I managed to install the OS 4.3.3 with redsn0w_mac_0.9.8b4 after several other unsuccessful combinations.

      You can’t because Ultrasn0w doesn’t support that BB in the first place. You need to update it to an iPad BB first if you want an unlock. Follow this http://bit.ly/jVI3cT.

    PLEASE HELP!!

    I have an IP3gs w/ bb 06.15.00, custom ispw 4.3.3 from sn0wbreeze, and everything appears to be fine. However, when i install ultrasn0w from cydia, the phone has “no service”, reboots, often reboots and the modem info is 00:00:00:00:00, and the wifi is grayed out. i have tried rebooting, reinstalling custom ispw, toggle airplane mode, etc. if it does work, it only works for a moment, then back to “no service”. i believe this is an issue with ultrasn0w, because until i install ultrasn0w, my wifi stays locked on and solid. also, my sim works in other phones, and stock at&t activated sim works in mine with no issues.

    any suggestions?

      Your iP3GS is bricked for life. Its a hardware issue with the baseband chip of your iPhone. As Wifi and Bluetooth are a part of baseband chip, so they wont work until BB chip get replaced. Neither iTunes will be able to gather any info from the BB chip of your device due to a missing IMEI/Mac Address. Your chip will no longer function & you’ll loose the functionality of your BT & Wi-FI. Ultimately you’ll not be able to place any calls anymore. All these options will be totally greyed out on your device. Your BB chip is damaged. If your still under warranty, make sure you take it to the local Apple Store.

    HiAll,

    I follwed the same procedure, verything work fines, after Ultrasn0w 1.2.3, task is completed it ask for me to reboot.

    I had rebooted the device, it shown me all the updated version.

    1. Repalce with another sim.
    2. Went settings>Airplane mode on is made it to off.
    3. Then rebooted still shows me same error.
    4. Replaced with orginal sim, it started working.

    So key settings is airplane mode settings.

      Pramod3 years, 3 months ago

      Did you try popping in a different SIM into your iP3G to see if its behaving in the same manner? Probably from your friends iPhone? It seems like its a SIM specific issue and not related to your iPhone as its able to read the carrier and the signal strength perfectly for you.

    Hi Wolverine/Pramod

    I am now stuck with the issue of only having 1 signal bar. I still can make calls and receive SMS. After reading through this website for 1 whole day i still have not much clues on how to solve the problem.. Please help!

    I am using iphone 4, jailbreak using Redsn0w 0.9.6rc16 to 4.3.3. My current baseband is 02.10.04. Can i solve the problem by installing Ultrasn0w 1.2.3? Please advice thanks!

    •  
      Pramod3 years, 3 months ago

      Yes, since you have preserved your BB (which is absolutely not required in the case of an iP4), you can use Ultrasn0w to solve the single bar issue with ease.

    how can i activate my brand new iphone 4 without sim?

    •  
      Pramod3 years, 3 months ago

      You can activate (not unlock) your iP4 by simply popping in the official carrier SIM that came locked with your iP4. Once you have inserted the SIM, connect it to iTunes and your good to go.

    •  
      Pramod3 years, 3 months ago

      That’s because your probably stuck at the Emergency Call screen. You’ll need to pop in the official carrier SIM that came locked with your iPhone first and then connect it to iTunes to get started. After that, follow this guide http://bit.ly/jIVot1to get yourself unlocked using the Gevey.

    •  
      Pramod3 years, 3 months ago

      You need not do that. Why don’t you try popping in a different SIM (probably from a different carrier) from an another iPhone of your friend that works to see if its still showing you the same issue? It could be a carrier specific issue as well.

      With OpenSSH, you can browse the internal file system of the iPhone. A much easier way to do this is by using iFunBox which can be downloaded from here.

    hi pramod…what is OpenSSH (browse the file system) or secure shell?

      Its both. A utility that allows you to SSH into your iPhone and run terminal commands & do lot many more things like accessing the Raw File System of the iPhone and so on.

    hi pramod…..could please xplain how SSH works on Iphone 3gs?

    •  
      Pramod3 years, 3 months ago

      SHSH Blob is a signature file which is verified against Apple Server to verify if the iPhone is running the latest version of iOS. If for some reason, when you are try to restore to a previous version, Apple will not allow you to restore it becuase, you are trying load a older version of iOS. To make this possible, we need to send a request to a different server (Local or designated) which sends a SHSH blob (which was saved by you) back to iTunes faking that its the current version. Downgrading the iOS in such a manner is necessary for iOS jailbreaking, since an older software may have known exploits & you need not remain stuck on the latest iOS firmware w/o a JB.

  •  
    zafar3 years, 3 months ago

    oh but ultrasn0w does not seem to be working…. i get just a 1 bar range and no carrier settings(i cant see the list )
    also is it possible that ultrasn0w doesnt work because i use the offline method to install it… (phone has a wifi problem too)

    •  
      Pramod3 years, 3 months ago

      If you have installed Ultrasn0w manually via iPhone Explorer, you’ll also need to add in the MobileSubstrate.deb along with the Ultrasn0w.deb for AutoInstall. Right now, Ultrasn0w is not properly installed on your iPhone and hence the No Service message as MobileSubstrate is missing. Downlaod and install MobileSubstrate just like how you installed Ultrasn0w 1.2.3.
      Here you go: Ultrasn0w 1.2.3 + MobileSubstrate.

      No. There is no way to come back/undo yourself from the iPad BB once you have updated it. :(

    •  
      Pramod3 years, 3 months ago

      Yes, Ultrasn0w will definitely unlock your iPhone & Ultrasn0w is the only way to complete your unlock on the iP3GS. There’s no other alternative.

    Please Help me, i done everytyhing for my Iphone 3gs but it is impossible unlock, in this moment my iphone is 4.3.3 baseban 6.15.0, but when unlock with cydia the process is normal but when try to call said !You have call barring activate for this mobile services!, what i need do?

    •  
      Pramod3 years, 3 months ago

      This is not an issue with your iPhone. Your able to place a call with full signal bars as well as the Carrier name display. Am I right?
      Your SIM instead is causing this trouble. Call up your carrier to see what’s the issue. Alternatively try a different SIM as well. This time, you should be able to place calls w/o a hitch.

  •  
    FoxTrot3 years, 3 months ago

    Already try with another SIM same carrier and from another carrier with the same issue. No service

    •  
      Pramod3 years, 3 months ago

      Have you completed the unlock by using Ultrasn0w 1.2.3? If yes, is it recognizing your AT&T SIM atleast? Pop it in and see if its still showing No Service.
      Custom restore alone will not complete your unlock procedure. You’ll need to download Ultrasn0w from Cydia and install it as well for your SIM to get recognized.

      •  
        FoxTrot3 years, 3 months ago

        I do not own an AT&T SIM. I did install UltasnOw with success. Like I said in my original post the SIM from FIDO is recognize. After an reboot It connect only for one minute with only one bar but the signal was lost. Is it possible that I have an Hardware issue? My WiFi connection work only when I am in 20 feet of the router.

        •  
          Pramod3 years, 3 months ago

          I really don’t think its anything to do with your h/w since your SIM is being read/recognized and you have no Wi-Fi problems. Also, the Wi-Fi antenna of the iPhone is not as powerful as your Laptop and therefore you need to be atleast somewhere near to your hotspot & not very far.
          What i would like to suggest at this point is to do a fresh restore & JB using custom IPSW to see if the problem still persists.

  •  
    FoxTrot3 years, 3 months ago

    I have an iPhone 3GS with ATT carrier 4.3.3/05.12.01. (New Carrier FIDO) (custom firmware build by pwnage tool 4.3.3.1) I follow the how to with success. The SIM is recognise (carrier/IMEI OK) but I have an No Service issue.
    The SIM card work fine in my old phone.

        Yes I try. No effect

        •

          Did you try a couple of reboots as well? Does the problem still show up?

          •  
            Pramod3 years, 3 months ago

            What you can try is to use a different SIM from the same carrier to see if it runs fine then (Ask your friend). Sometimes, it could be a SIM specific issue as well.

    •  
      Pramod3 years, 4 months ago

      You’ll need to call up 3 UK and ask them to unlock it for you via your IMEI details. Once you give them your IMEI, they will send you back an unlock code that needs to be entered. After that, your Nokia phone gets factory unlocked. Unfortunately, only 3 UK knows this unique code and only they can provide you with the necessary details to help you out.

    also got a 3g showing no sim, they tell me its a logic board issue.

    any help thanks

    •  
      Pramod3 years, 4 months ago

      Both seems to be a h/w problem. These problems are hard to be rectified by s/w unlocks or jailbreaks. You’ll need to tell me exactly from when have been facing these issues on your iPhone to get a better idea.

    •  
      Pramod3 years, 4 months ago

      NO you can’t. It’ll still give you the No Signal Issue. Please follow what I have suggested in my previous comment. You should already be having the stock IPSW file right? Else how did you create the Custom Restore file on your Mac as you stated earlier?

    it was a factory unlocked one with 4.2.1…after jailbreaking to 4.3.3 i dont get any signals..

    •  
      Pramod3 years, 4 months ago

      You really need not preserve your BB as you have a factory unlocked iP3GS. By using PwnageTool, you have unnecessarily preserved your BB on a factory unlocked iPhone along with the restore (your BB should have been 05.16.02) and therefore the No signal bars issue. Go ahead and restore your iPhone to Apple’s Stock (Original) 4.3.3 IPSW via iTunes without any PwnageTool/Sn0wB intervention. After it restores back, your good to go with full signal bars.
      Jailbreak it later with Redsn0w like this: http://bit.ly/kPhfh0

    Hi I have a 3gs which was on 4.2.1 and 05.15.04 bb. Using redsn0w I installed cydia and with ultrasn0w I jailbroke. Then with redsn0w i changed baseband to 06.15.00. When i put in a sim which works with my other phone I get sim failure notice.I am on 4.3.3 now.the serial number seems to be in the middle between new and old.#82943k7g3np.when I install old sim it says searching or no service.But I am in a different country then where the original sim is from.Sim works fine in my other iphone.Thanks for any help.

    •  
      Pramod3 years, 4 months ago

      Make sure you have your 3G set to OFF to see if your getting a complete signal strength. Also try the same with a SIM belonging to a different carrier to see if the problem persists. Searching.. means that your unlock is fine, but something’s wrong with the SIM. Try it with a different carrier and let me know.

  •  
    Shibs3 years, 4 months ago

    So what will i do next?
    Still I cant make calls.
    Is This hactivation means unlocking with ultrasnow?

    •  
      Pramod3 years, 4 months ago

      Hacktivation merely means official activation via iTunes to get your PushNotifiactions/FaceTime activated. So NO, hacktivation is not the same as what Ultrasn0w does. As for your problem, its definitely your SIM/carrier that causing this issue. The unlock is just fine as your able to receive a signal. That itself confirms the unlock is good. Make sure you switch OFF 3G if its not supported by your service provider as well and see if it works.

    modem firmware-06.15.00

    How can check an iphone is factory unlocked or not with the model number?

    •  
      Pramod3 years, 4 months ago

      With the model number, you cannot really know whether your iPhone was locked or not. Model number purely shows you only the country in which the iPhone was sold, which in this case is in UK. To know whether your iPhone is factory unlocked, all you need to do is pop in any SIM and your iPhone should be able to get itself activated over iTUnes w/o the need for Hacktivation.

    Hyster3 years, 4 months ago

    Hi there, I have jailbroken a 3gs using Snowbreeze (2.7.3) and then unlocked it with ultrasnow (1.2.3).

    I am on 4.3.3 and running 6.15.0

    The phone worked perfectly for a week or so then….

    I am getting the message “could not activate cellular data network”

    “cannot open page safari cannnot open the page because it is not connected to the internet.”

    I have my carriers name (top right) and the 3g sign and a strong signal, but keep getting these errors.

    I’ve checked and rechecked the APN, user name and password and they are all correct, disabling and restarting 3g makes no difference.

    Strangely if I reboot the phone and search in safari it connects to the page and then throws up the error.

    I’m a noob to jailbreaking and would appreciate any help.

    Wifi works fine.

    •  
      Pramod3 years, 4 months ago

      Make sure the Data service is activated from your carrier’s side on your SIM. To confirm, pop in this SIM into another phone & check if data accessibility is available/not. If not, your not registered for data services just yet.

      •  
        Hyster3 years, 4 months ago

        Cheers for your reply Pramod, I put the sim in an Android phone I have and it connects to internet no problem using data….

        I’ve uninstalled and reinstalled ultrasnow, even wiped it and restored with a custom rom (that was a drama). Still no joy, sms and calls are fine, just no data.

        •  
          Pramod3 years, 4 months ago

          You need APN settings for your carrier. Have you entered them in ? If not, you’ll need to enter them according to the name of your carrier. Follow this:
          1. Connect your iPhone to some wifi/wireless network which can give your iPhone Internet access.
          2. From your iPhone Safari browser, open the website : unlockit.co.nz and click Continue.
          3. Click on Custom APN.
          4. Type the APN settings for your carrier, and click on create profile.
          5. Save the profile and re-start your iPhone.
          Your phone should now be working with the data settings. :)

    •

      No, SAM is only for official activation of the iPhone for resolving PushNotifications problems. What is your current iPhone details? Like iOS & Baseband & your iPhone model as well.

    what is the diff b/w custom restore,normal restore & jail breaking?

    •  
      Pramod3 years, 4 months ago

      For restoring via Pwnage Tool, here is the guide: http://bit.ly/mO3uXj. :)

      Custom Restore: Uses a modified IPSW that preserves the Baseband while updating your iOS. Used commonly by those who rely on an unlock. Includes Jailbreaking & can unlock capabilities can be added as well.
      Normal Restore: Will update your iOS & BB to the latest. Never to be used by those who rely on an unlock.
      Jailbreaking: Gaining complete access to your iPhone for customizations, themes, tweaks, icons etc..

  •  
    Shibs3 years, 4 months ago

    If i do a custom restore how wil i unlock… My iphone is not a factory unlocked one…is thre any option for unlock without jb…. Plz xplain the steps of shsh blob… If u hav free time

    •  
      Pramod3 years, 4 months ago

      When you complete your custom restore, you’ll have Cydia already in it. Download Ultrasn0w from Cydia to complete the jailbreak. Follow this guide http://bit.ly/mbFORU closely to understand how to cook a custom IPSW for you to restore. Once done, you may unlock via Ultrasn0w.
      Note: Make sure you take a backup before the restore process, because it’ll erase everything that you had on your iPhone.

  •  
    Shibs3 years, 4 months ago

    I hav tried that too…. D same thing happeng with other carriers too…. May i jail brake it again? Can i downgrade this to 4.2? Plz help me…

    •  
      Pramod3 years, 4 months ago

      Jailbreak will return you with the same situation, so re-jailbreaking is not a good idea. You can try a complete fresh Custom Restore of 4.3.3 to see if it still exists. Yes, you can downgrade yourself to 4.2.1 if you have the SHSH blob saved for the same via Cydia.

      Definitely seems to be something wrong with the SIM you are trying to call from. Nothing’s wrong with your iPhone because your able to get the carrier signal as well as get incoming calls. The unlock works perfect. Pop in another SIM (your friend’s) of the same carrier to see if the error still persists. If not, then your SIM needs to get replaced.

        thanx for d reply pramod….but i hav tried with 3 other sim..it persists..and i’ve also jailbrakn again with pwage and unlockd with ultrasnow…this time i could make 4 to 5 calls, after 1 hour the same problem came again….
        one more thing:- my iphone 3gs was jail broken with tethered ios 4.2 or somthng…and there was an app in the springbord like APN unlock…i’ve deleated that app after the jailbreak(ios 4.3.3 untethered).i dnt knw what was it actually….

        •  
          Pramod3 years, 4 months ago

          APN unlock is nothing but carrier settings for your iPhone to access GPRS & Data connectivity, MMS and so on. It has nothing to do with the unlock/carrier signal problems. Make sure your 3G is OFF because sometime due to intermittent connectivity problems it could cause this but not quite sure. Since you have tried with 3 different SIM’s of the same carrier, now try with a different carrier to see if the problem persists. I’m guessing you won’t.

    I gust re-jailbraket my 3GS and get the BB to 06.15.00…but, not furder:(When i open Cydia,, Unable to Load” appears.Iven if I have an Internet con via USB.So, I can’t download ultarsn0w!What shoud I do?

    •  
      Pramod3 years, 4 months ago

      Use a Wi-Fi instead because internet tethering will not work from your SIM unless you unlock the iPhone. The best way is to access a Wi-Fi hotspot and download Ultrasn0w. That is the most complete method to unlock.

    Just want to confirm. There isn’t a fix yet for iphone 3gs bb 05.16.02?

    •  
      Pramod3 years, 4 months ago

      If by fix you mean an unlock, Nope. Updating to the iPad BB is the only option.

    Hi, I updated my baseband to 6.15.00, did what it said in all the articles abouth changing to ipad baseband. It went perfect and my phone got unlocked. Was one of the lucky ones who didnt have any GPS problems or WIFI. Its all good just besides the unlock. Few days later, about 4-5 days it stopped working. I had the No Service. I read about this in several of forums and I couldnt find the fix.
    I did all, reinstalled, rebooted Ultrasn0w, delete ultrasn0w, turned off and on the airplane mode, rested the network settings, downloaded the cydia.pushfix.info source, and the fix carrier option ++ I think I did about all. Whats missing? My iPhone is a 3GS 4.3.3. baseband 6.15.00 . Everytime a put a sim card, it finds the carrier on the “settings; about the phone”. But it just dont want to give me the network service!

    HEeeelllpppp, from a frustraded girl in Oslo, Norway

    •  
      Pramod3 years, 4 months ago

      Does it happen to every SIM you insert into the iPhone? Try to pop in a different SIM to see if the problem still persists and let me know. If yes, we’ll need to do a complete custom restore because since you told it worked well so far, there’s no problem with the iPhone either.

      •  
        Mira3 years, 4 months ago

        It worked when i switched to a differnt sim, the other simcard worked, and after i put back my pen simcard it found ut, it work but then it stopped again. It was unlocked for about 5mins.. Other simcards works, just not mine. My simcard works on all other phones just not on my unlockef phone. Like i said, it worked with a différent sim and carrier, just not mine. Any idea why? Whats strange is that it worked before :s thanx for the help:)

      •  
        mira3 years, 4 months ago

        Thanks for the quick answear, I changed the sim card with a different carrier, and it worked with that. Then I put back MY simcard, it worked for about 5-9 minutes, and suddently it went back to No service.. Didnt last very long.. But it strange, cause in all other phones my simcard works, just not on the 3GS. With the other simcard it worked all the time. Never went to No serive. So what I dont understand is why it cant accepts my sim…
        I guess its okey, cause I just bought a new simcard:p same number just different carrier.:p
        But I would like an explanation on how to fix it (if there is)..
        MANY THANKS :D

        •  
          Pramod3 years, 4 months ago

          Yep, that confirms it. Definitely a SIM/Carrier specific issue there. If your old SIM was T-Mobile, you’ll need to keep your 3G OFF, because iPhone 4’s hardware simply does not support the 3G frequency of T-Mobile. Was it T-Mobile ?

          •  
            Mira3 years, 4 months ago

            The carrier is Telenor (norwegian). But how is that, because it worked before.. Telenor is the one that lasts for about 10min then to No serivce while all the others surivives.

          •  
            Pramod3 years, 4 months ago

            Nope, no idea. Give another Telenor SIM a try in your iPhone to see if its SIM specific. In that case, you can make sure its a problem with your SIM itself if the other Telenor works.

    Hi! I’ve just spent the whole night trying to fix my Iphone 4 with no luck so I’d be pretty happy if anyone could help since I need it working asap :(
    Its a new Iphone 4 from AT&T, unlocked via gevey, ios 4.3.3, baseband 04.10.01.
    I tried to jailbreak it via Snowbreeze 2.7 and in the end itunes told me that “the SIM card inserted in this iPhone does not appear to be supported”.
    Now it’s locked and I can only make emergency calls until I activate it with the carrier’s SIM. Should I just buy one AT&T card and finish the activation with it and hold my breath that it works again with my other card and gevey or..? Please help, I’m going crazy ove here :) Tnx!

    •  
      Pramod3 years, 4 months ago

      Since its a new AT&T iPhone 4, I’m sure that you will be also having the official SIM that came along with the iPhone as well. All what you need to do is:
      Remove the Gevey & put in the original SIM tray along with your AT&T SIM. After that connect to iTunes and you’ll be officially activated instantly. You don’t need to hold your breath, because it definitely works. :)

      •  
        Lena3 years, 4 months ago

        I don’t have it but I can go buy it.. And after that I will be able to put back my other card with Gevey and it’s gonna work? Thank you so much for the fast response ;)

      •  
        Lena3 years, 4 months ago

        Sorry for bothering again, just went to AT&T to buy a new sim card but I need to take their monthly plan to do so.. Which is not a good option for me.. Do you maybe know where I can get the AT&T deactivated card cheap and as quick as possible? eBay is also not an option.. And sorry if I’m asking silly questions, I just moved to US and don’t know a bunch of this everyday stuff..

        •  
          Pramod3 years, 4 months ago

          Get it from any of your friends/co-workers. Any AT&T SIM will do to get you officially activated. Don’t buy it from them, they’ll definitely charge you for it.

          •  
            Lena3 years, 4 months ago

            I needed it fast and couldnt find it anywhere so I went to a third party “mobile” store near my place and left the phone there for 20 dollars and the guy fixed it somehow, without putting the at&t card in it because i asked for it before, no one had it in there.. Don’t know how he did it, wouldnt tell me, but it works now..

            The only thing I dont get is why I can’t use 3G?! Every time I turned on 3G I’d get “No service” or smt like that and then had to redo the whole unlocking proces at least five times before it would work.. Maybe you know why and how to fix it?

            Tnx once again!

          •  
            Pramod3 years, 4 months ago

            Gr8. I’m sure they had an AT&T card somewhere around. :D
            For the No Service problem, I suppose you have popped in a T-Mobile carrier SIM right? iPhones doesn’t support T-Mobile’s 3G frequency. The hardware itself simply will not read the 3G signal off T-Mobile & hence the No Service.

    Help me I have restored successfully iPhone 3gs to firmware 4.3.3, baseband 6.15.00
    New bootrom. Installed ultrasn0w latest version. But just get no service at all. Can manually choose vodafone network, says network restricted. phone had been previously unlocked and working on 4.1, but then user updated to 4.3.3 official .

    At first I used redsnow and updated to iPad baseband. Didn’t work!
    Then went to 4.21 with snowbreeze but no service.

    Now on 4.3.3 custom hactivated snowbreze with iPad baseband, ultrasn0w latest but no service.

    Please please help me. Available for remote desktop and webcam
    Assistance. Spent 5 days trying to get this working

    Much appreciated

    •  
      Pramod3 years, 4 months ago

      Looks like something’s troubling the SIM. Did you try popping in a different SIM to see if its behaving in the same manner? No Service shows that your unlock is just fine, and the fact that your also getting a list of all the carriers also proves that. Try out a different SIM and let us know.

      •  
        Beretta0073 years, 4 months ago

        Yes tried my wifes sim too and get same issue. Hers is same network. As mine though. Hers works fine in her 3G unlocked 3.1.2. Her back light has gone which is why I need to get this other phone working

        •  
          Pramod3 years, 4 months ago

          Try to uninstall and re-install ultrasn0w. Also try a SIM of different carrier as well. Sometimes if the 3G isn’t that great in your area, you may have problems. Is your iPhone able to grab a signal? Or atleast able to catch the name of the available networks across the area via the manual searching? Check them and let me know.

    Hi Wolverine

    HELP !!!.. I bought an Iphone 3gs (4.3.3. 06.15.00) from eBay that was locked to AT&T. Did research on the net and did the following – create customer IPSW package – followed instructions to go into DFS mode – Got Cydia installed – Through Cydia installed Ultranow 1.2.3 and unlocked phone.

    Everythign was working fine till I tried to install some apps through Cydia, phone got stuck and connected to iTunes and got into Recovery mode. Since then tried to do the following

    – Shift + Restore – custom package – error recovering
    – Restore normal – error restoring
    – downloaded Fix Recover – lot of commands ran on black screen on the phone – still it is stuck with iTunes mentioned on the screen – except this time I have emergency call slide option
    – installed latest Tinyumbrella clicked on all options but no results

    I have no idea what SHSH is. Please help, this phone was a gift for my wife.

    Regards
    Sumit

    •  
      Pramod3 years, 4 months ago

      No worries. All you need to do is to re-create a 4.3.3 IPSW custom firmware using Sn0wbreeze and use it as the restore IPSW file for iTunes. Everything will work just fine because your not encountering any errors on the way. Download the latest Sn0wbreeze and follow this guide here http://bit.ly/lujZTw using the Shift+restore method. Just be patient and give it sometime. Everything will fall into place. Good luck. :)

    Hey

    I am having problems with my iphone! I originally I am from Canada but i moved to Netherlands so I unlocked my iphone3g on an older firmware and it worked perfectly in the netherlands but I had battery life issues.So i decided to update my firmware and i shoulda read more into it but the firmware i updated to wasn’t unlockable the only way was with the ipad baseband. so i did and i have regreted that decision for awhile! so hears my problem i get signal sometimes its full bars or 1 bar.. and it works i can send sms.. but it doesn’t last for long it varies times it last then it goes and searches for signal and some times it reconnects but most of the time its says no service! So i toggle airplane mode so it searches again but most of the time says no service but i know for a fact i should have full bars..It some times gets one bar and i quickly go to my message app and quickly try to send a message but it then loses signal..its like its playing a game with me.. and i dont wanna play… Any help would be greatly appreciated!

    My stats on my iphone 3g :

    4.1
    Model:MB489C
    baseband: 6.15.00
    baseloader : 6.04

    I also used 1.2.3 ultrasnow but still signal problems please help!!

    •  
      Pramod3 years, 4 months ago

      This problem is purely because of the coverage in your area. Sometimes if 3G services (if enabled) aren’t that great in your area, the signal drops and comes back every now and then. Make sure your area has a good coverage in your area for the carrier signal your using. Try disabling 3G and whilst on EDGE, see if the problem persists. Make sure that the SIM also works fine in other phones as well. Hope this helps. :)

    Harshan3 years, 4 months ago

    Hi Volverine,

    Have been stuck with my new iphone for two days. It was all fine until I decided to plug it with iTunes. iTunes suggested that there is an update available and I gave it a try without saving/backing up SHSH files or whatever since I didn’t know updating with iTunes can be deadly. After updating with iTunes, phone went into recovery mode. Then I tried using tinyumbrella to kick it out of recovery mode which didn’t work. Frustrated, I tried restoring which again ended up giving an error. Then downloaded 4.1 ispw, downgraded to 4.1 and then used exit recovery of tinyumbrella. This time it went out of recovery but was inactive/locked.

    downloaded snowbreeze and created customer ispw using 4.3.3 and restored using itunes and I didn’t click upgrade base band to 06.15.00. Presto! it did started up, I could go inside, cydia was installed. But after I inserted the SIM card which I used with iphone for couple of days before this issue popped up wasn’t recognized, no signal and no services. When I search for the carrier list, it didn’t give any information.

    As I read in this forum and some around, there’s no solution for this issue as I’ve accidentally upgraded base band of my iphone (during the first attempt of upgrading using itunes)

    I haven’t tried installing anything on cydia as I don’t have a wireless network around.

    Do you think I have a way out ?

    Cheers!

    hi,

    ok been reading with hope but no luck.

    got 3gs, baseband 06.15, firmware 4.3.3, new bootrom,model mc132 (iforecast v1.2 says only jailbreakable with shsh blobs and is NOT unlockable) and the dreaded no service, carrier shows orange but no bars and instant call failed, have ultrasn0w 1.2.3 installed and was originally on orange so im told. was ok so im told but think previous owner messed around because it was stuck in recovery mode.

    imei not blocked from what i can find out.

    have some blobs, 4.1, 4.3, 4.3.1, 4.3.2

    know i cant go back to stock because of baseband (any news on the downgrade baseband fix yet mate)

    no idea if phone was previously factory unlocked.

    •  
      Wolverine3 years, 5 months ago

      I will recommend you to downgrade to iOS 4.1 CFW and then try to install Ultrasn0w 1.2.3. I have iPhone 3GS with iPad bb and its fully jailbroken and unlocked on iOS 4.1.

      Here are things you need to check before downgrading:
      1. You upgraded the baseband of your factory unlocked iPhone 3GS
      2. You selected the wrong bootrom version while upgrading your bb to iPad bb
      3. When you installed Ultrasn0w, “Enable 3G” option in Settings app was turn ON
      4. You never rebooted your iPhone after installing Ultrasn0w
      5. You upgraded Cydia before installing Ultrasn0w (Ultrasn0w should be the first one which should be installed) (Worked for many)
      6. This tip is stupid one (as Redsn0w 0.9.6RC16 JB is untethered) but some people reported that after booting into tethered mode (Using Redsn0w), they managed to get rid of this issue.

      According to this dude http://bit.ly/kICsCd Diptup, he tried to install Ultrasn0w offline and it never worked for him. So he installed over Wifi and it worked like a charm.

      According to this dude http://bit.ly/lMW5Ay Ulhas Dhuri, he can only clamp to network when Enable 3G option is OFF.

    dwsulliv3 years, 5 months ago

    please help me…. I just upgraded my 3GS iphone to new firmware 4.3.3, and suddenly the phone went to DFU (no iphone logo just blank). I have tried all the solution that I found that did not work.

    following is the detail story:

    1st, I jailbrroken my iphone with redsn0w to 4.3.3, and upgraded the ipad baseband.

    after upgrade I had problem with “no signal” and than I installed ultrasn0w, but got error, the installation was not success. I realized after I read some article in forum that 3gs could be fix with ultrasn0w.

    Suddenly after sometime the iphone went off, I could not tether with any software. I tried redsnow 0.9.6RC16, but stuck in the waiting for update process, and seems that redsn0w could not communicate with my iphone. previously was worked as I used redsn0w for tethered.

    I already uses IREB, redsn0w and any other software but It does not help.
    I can put my iphone to DFU mode, and Itune can detect my iphone in the restore mode. but I could not do anything.
    I could not restore to normal IOS due to my baseband is already changed.

    Could anyone help, and give me the solution? I just want my iphone alive and could boot again.

    •  
      Wolverine3 years, 5 months ago

      As you are iPhone 3GS user with iPad baseband, so you can not restore stock iOS 4.3.3 IPSW on your iPhone. For some reason your iPhone firmware is corrupt and this is why you are unable to boot your iPhone. Your iPhone is not in DFU mode (NOT Pwned DFU mode). To fix your iPhone, create iOS 4.3.3 IPSW with PwnageTool 4.3.3 http://bit.ly/jMpbKR or Sn0wbreeze 2.7 http://bit.ly/k5I7Qu After creating custom IPSW, restore it with iTunes. If you encounter any restore error, feel free to ask me here. Also note that if you are creating iOS 4.3.3 custom IPSW using Sn0wbreeze 2.7, do not choose “Install 06.15.00 iPad baseband” option (Step 5) as your iPhone is already on iPad bb.

    Hi Wolverine,

    As you mentioned in UPDATE#1 above , I faced problems unlocking on my iPhone
    3gs (MC640LL) which has a new-bootrom. The only work around that is possible for
    me right now is setting “Enable 3G” to OFF. I can then clamp to network.

    Please reply incase if u have some better solution to this.

      Wolverine3 years, 5 months ago

      Of course you need your iPhone to connect to a Wifi with an active internet connection to install Ultrasn0w 1.2.3. If you do not have Wifi router, Internet or SSH access, use this guide http://bit.ly/mEpZ8z

        Firm ware 4.1

          These are the firmware versions. I want you to tell me whats written in-front of “Modem Firmware” option.

          •  
            Kim3 years, 5 months ago

            Modem firmware is the 04.10.01

          •  
            Wolverine3 years, 5 months ago

            Sorry but Ultrasn0w can not unlock iPhone 4 baseband 04.10.01. You can unlock it using Gevey SIM for now. There is no other way to unlock iPhone 4 04.10.01 baseband.

          •  
            Kim3 years, 5 months ago

            Is there any other program that will do it?

            Wolverine3 years, 5 months ago

            Sorry, NO software can unlock iPhone 4 baseband 04.10.01 baseband. Only Gevey SIM http://bit.ly/f2n5VU can unlock iPhone 4 all basebands on all firmwares.

    Hi,

    Thanks everyone for your hard work on this! I finally after two solid days of isolated iteration I got this one to work. Thannnk Yoouuu!

  •  
    Mran3 years, 5 months ago

    The isn’t stolen but lost and then found. I bought it off the person who lost it. I tried a sim from the provider that it was previously on and it worked. Am I still unable to unlock?
    Thanks for the reply

    •  
      Wolverine3 years, 5 months ago

      Yep! Its because the other carrier has not blacklisted the IMEI of this iPhone yet. Sooner or later, it will be blocked on all carriers. Your iPhone is already unlocked.

      •  
        Mran3 years, 5 months ago

        Oh ok. I’ll ask my friend if he can report it as found or something. Hopefully the network will unblock it? If not is there a way of changing the imei?

        •  
          Wolverine3 years, 5 months ago

          Changing IMEI is strictly illegal, however you can request the original owner to get it unblocked by requesting the carrier. Also note that you can easily get tracked by police if you try to put that SIM in your iPhone again.

  •  
    MRAN3 years, 5 months ago

    i’ve done the above process (at the very top)

    Looked like it was ok, in settings it now says…

    Network: Telstra mobile (which is the SIM i put in the phone)
    Line: Telstra
    Version: 4.3.3
    Carrier: Telstra 10.0
    Modem Firmware: 06.15.00

    So i tried to call to test it out, but it says “this handset has been blocked on this network, for further information….”

    have i done something wrong?

    Thanks

      Ops. You are using a stolen iPhone whose IMEI has been blocked. Throw it away before police knocks your door.

    Iphone: Did you ever fix your problem with no signal. It seems that we are experiencing the same problem.

    •  
      Wolverine3 years, 5 months ago

      Yep, he did 2 mistakes (Talked to him in detail on chat):
      1. Upgraded his factory unlocked iPhone 3GS to iPad baseband
      2. He selected old bootrom while jailbreaking his iPhone with Redsn0w (He had actually new bootrom iPhone 3GS)

      •  
        Fetflex3 years, 5 months ago

        Mine 3GS is not factory unlocked so is the solution still suitable for me?

        What bootrom did he use?

        •  
          Wolverine3 years, 5 months ago

          Yes, the above procedure is valid for you until you have unlockable baseband. What is your current baseband? To know about ur bootrom version, use iDetector http://bit.ly/eNTqmG

          •  
            Fetflex3 years, 5 months ago

            I have updated the iPhone to the Ipad baseband 06.15.00 and it’s a new bootrom.

          •  
            Wolverine3 years, 5 months ago

            Great. You can use the above method to unlock your iPhone 3GS.

  •  
    thelionsword3 years, 5 months ago

    I unlocked my 3GS 16GB iphone with redsn0w_mac_0.9.6rc16 4.3.3 firmware and 16.15.00 base band and am doing just fine.

    You have to remember that only the proper basebands will support carrier service. I kept hitting my head against the wall with a 15.16.02 bb.

    You might be wary of upgrading to the 4.3.3 firmware (iPhone2,1_4.3.3_8J2_Restore.ipsw) because you may find yourself forced to then upgrade your baseband to 6.15.00 (iPad not iPhone) but I did it and it with my t-mobile pay as you go sim card and it works fine, great even. Some people’s GPS will FAIL in 16.15.00, but at least the phone works, at least until a better workaround to downgrade phones back to a 4.2.x firmware comes along.

    •  
      thelionsword3 years, 5 months ago

      you can use pwnage tool to jailbreak into the 4.3.3 firmware and preserve your baseband, but then you may run into the same problem as before where you can’t get your carrier service to work because remember, 15.16.xx is not supported in any unlock.

    •  
      Wolverine3 years, 5 months ago

      Your GPS works? If yes then do you get accurate coordinates?

  •  
    Tiger793 years, 5 months ago

    Ok… here’s what I have…

    1. iPhone 4 (ipsw V4.1)
    2. PwnageTool V4.3.3
    3. Stock ipsw V4.3.3
    4. Macbook Pro w/ iTunes V10.2.2

    I was about to proceed with the untethered 4.3.3 jailbreak. I bought this phone off newegg.com and it was listed as unlocked, but I’m not so sure.

    So I’ve read through the 4.3.3 untethered jailbreak process and line16 states that if I rely on an ulocked iPhone, use Ultrasn0w 1.2.3 through Cydia. Then I read through this guide and it states that it doesn’t support bb 02.10.04.. I’m assuming this is my bb as this is what is listed under settings>general>about>modem firmware = 02.10.04

    My question is will i be able to complete this untethered 4.3.3. jailbreak process if my bb is 02.10.04 and if not is it possible to change the indicated bb to one that is supported?

    Also, is there a way to confirm that this is an unlocked phone? I’m currently in Afghanistan and don’t even know if this is possible. Any assistance would be greatly appreciated.

    •  
      Wolverine3 years, 5 months ago

      Yep, jailbreak has nothing to do with the baseband until you are restoring a custom IPSW. You can always jailbreak iOS 4.3.3 on your iPhone 4 using iOS 4.3.3 custom IPSW made with PwnageTool. The custom IPSW will NEVER touch your current baseband version. You need to tell me the model version of iPhone (Settings -> General -> About -> Model). I don’t think there is any carrier in Afghanistan which officially support iPhone contract. So it must be a factory unlocked unit.

      •  
        Tiger793 years, 5 months ago

        Model: MC610LL

        How can i determine if it’s factory unlocked?

        •  
          Wolverine3 years, 5 months ago

          If your baseband is 02.10.01 and you can use other Afgani SIM cards in your iPhone then it should be factory unlocked. From the model number, your iPhone is 32GB black model which is locked to AT&T.

          •  
            Tiger793 years, 5 months ago

            Yeah, I’ve upgraded the firmware using the pnwage tool… and then used a wifi hotspot to upload the Ultrasn0w install. It only has one signal bar sometime and other times it states ‘No Service’… I’m not real sure what I should do next. Any suggestions? I wonder if it would be possible to call AT&T for an unlock code (if that is even something exists)??

          •  
            Wolverine3 years, 5 months ago

            Mmmm. No, you should not have installed Ultrasn0w. Also Ultrasn0w can never unlock iPhone 4 02.10.01 bb. If it was factory unlocked iPhone, it should have worked without Ultrasn0w. All you need is to start iTunes and activate it. If it says insert proper AT&T SIM then it means it is locked to AT&T. Also dial *3001#12345#* and tell me your signal strength in dBs?

          •  
            Tiger793 years, 5 months ago

            Wolverine,

            I dialed the Field Test and I don’t see SS on the menu or any of the submenu.

            Also, with the current chip I have I never received a message that states “Insert Proper AT&T SIM”…

            What would you suggest next?

          •  
            Wolverine3 years, 5 months ago

            Just connect your iPhone to your PC and launch iTunes. If you see enter proper SIM to activate iPhone then it means your iPhone is locked. If it says your iPhone has been successfully activated, then it should be a factory unlocked iPhone. Anyways, you got iPhone 4 with 02.10.04 baseband and you are using some Afghani network? Right? This confirms that your iPhone is factory unlocked. Why? Because there is no tool which can actually unlock iPhone 4 02.10.04 baseband except Gevey SIM.

          •  
            Tiger793 years, 5 months ago

            Correct, I’m trying to use Roshand (Afghanistan Carrier) for GSM services… I plugged the phone into the computer and it asked if I wanted to restore synch… I did… there is still only one bar indicated… I tried to again do the Field Test number you gave me… this time it won’t even do that… I just press “Call” and it doesn’t do anything at all.

          •  
            Wolverine3 years, 5 months ago

            Nops. You are dialing that number wrong. It works in all conditions. Once you go into field test mode, see for the signal strength in dBs (Where signal-bars appear). If you can make calls and can do SMS then it means your iPhone is unlocked and the issue is the signal-bars. Either way, you must install Ultrasn0w 1.2.3 to fix-signal bars on your iPhone. If you do not want to install Ultrasn0w, you must upgrade your baseband to 04.10.01.

          •  
            Tiger793 years, 5 months ago

            Sorry, I believe the phone may have been synching at the time which is why I couldn’t do the field test. Regardless, it did the FT and the db= -113. I’ve never been able to make a successful phone call or text with this phone. BB = 02.10.04

          •  
            Wolverine3 years, 5 months ago

            -113 means 0 signal-strength which means your iPhone is locked. You need to call AT&T and see if you have an active-contract with them. 02.10.04 baseband is not unlockable using Ultrasn0w (Infact not possible with any other tool except Gevey SIM). So there is no way you can make call from your iPhone until its a factory unlocked iPhone 4. Your model number indicates that it is or may be in past it was locked to AT&T.

    Hey, (Also posted in a another one)

    I have an iPhone 3GS running on 4.2.1 firmware with a 6.15.00 baseband. My iPhone is not carried by AT&T(I have T-mobile) so I am having difficulty with iTunes, which is 10.2.2, reading it.

    It is stuck in recovery mode and displays the connect USB to iTunes sign.

    I’m just trying to jailbreak it and unlock it. Hopefully on 4.3.2 firmware or best available.

    So I plug my USB into the iPhone and then open iTunes and immediately get “iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes”

    I downloaded sn0wbreeze 2.6.1 and followed the procedure you posted elsewhere, did the iReb thing, I’ve done the tinyumbrella thing, I’ve restored to the sn0wbreeze 3GS 4.3.2, I’ve restored to the iPhone2,1_4.3.2_8H7, and I’ve put it in DFU mode.

    I’m just trying to figure out the proper sequence so my phone can be recognized by iTunes, get out of recovery mode, jailbroken and unlocked.

    I’ve experienced the following problems:

    The iPhone “iPhone” could not be restored. An unknown error occurred (1611).

    The iPhone cannot be used because the Apple Mobile Device service is not started

    An unknown error occurred (1600).

    And the one I mentioned at the top

    •  
      Wolverine3 years, 5 months ago

      To fix all 16xx errors, you need to use iREB http://bit.ly/g2WlkP As your iPhone 3GS has iPad baseband, so you can NEVER EVER restore stock IPSW on it otherwise you will go into infinite recovery mode loop. I would recommend you to jailbreak your iPhone on iOS 4.3.3 instead of iOS 4.3.2. Use Sn0wbreeze 2.7 to create iOS 4.3.3 custom IPSW and restore it with iTunes. If you are unsure about steps, follow this guide http://bit.ly/k5I7Qu To fix Apple Mobile Device error, either re-install iTunes or go to C:\Program Files (x86)\Common Files\Apple\Mobile Device Support and double-click on AppleMobileDeviceService.exe

      •  
        Domino3 years, 5 months ago

        Thanks for the reply

        So which do I do 1st, the iREB or the sn0wbreeze?

        And instead of re-installing iTunes I did the other one but what is exactly suppose to happen?

        Because when I double click it nothing really happens except for something quickly opening and closing

            iphone3 years, 5 months ago

            So what I can do now?
            But I just used this in the first steps in sn0wbreeze, later on, when I do SHIFT + Restore on iTunes, I use this “sn0wbreeze_iPhone 3GS-4.3.3″ which is automatically created by sn0wbreeze. Or it is still something wrong?

          •  
            Wolverine3 years, 5 months ago

            Nops! If you restored sn0wbreeze_iPhone 3GS-4.3.3 then its fine. You only need to install Ultrasn0w 1.2.3 using the above guide. If still it fails to unlock your iPhone then i will recommend you to restore your iPhone again with iOS 4.3.3
            custom IPSW.

          •  
            iphone3 years, 5 months ago

            I tried that for many times, it doesn’t help.. Maybe everything is ok with unlocking. Maybe problem is not here. I don’t understand and I don’t know what I can do more. Do you have any ideas?

          •  
            Wolverine3 years, 5 months ago

          •  
            Wolverine3 years, 5 months ago

            Looks to me something is wrong with the SIM slot in your iPhone, otherwise there is NO reason Ultrasn0w 1.2.3 will fail to unlock iPhone 3GS with iPad bb. U restored and installed Ultrasn0w which proves there is no iOS issue. You have also put your friend’s SIM card in your iPhone but it was not working which means there is a HW issue or may be its the issue with Sn0wbreeze 2.7 custom IPSW. iOS 4.3.3 custom IPSW made with PwnageTool might do the trick. You can get it here http://bit.ly/m5KSHI

          •  
            iphone3 years, 5 months ago

            But I should use this with sn0wbreeze?

          •  
            Wolverine3 years, 5 months ago

            Nops, use PwnageTool 4.3.3 as you have already restored iOS 4.3.3 custom IPSW made with Sn0wbreeze 2.7 which didn’t work for you. I though you don’t have a Mac, thats why i gave you a direct to iOS 4.3.3 custom IPSW for iP3GS made with PwnageTool 4.3.3.

          •  
            iphone3 years, 5 months ago

            I tried, but it still doesn’t help. With my friends Telia DK card, again it shows the name of operator, but I can do nothing. Nobody can’t call, and I can’t call (Call Failed). With my card the same No Service. So everything is the same even after PwnageTool..

            Wow, some little changes, but not so big. When I changed to Denmark, for few seconds there were an operator name (But just 1 signal bar) and then the same No service again :(

          •  
            Wolverine3 years, 5 months ago

            When you see 1-signal-bar, dial *3001#12345#* and tell me your signal-strength in dBs.

          •  
            iphone3 years, 5 months ago

            -113 with my friends card (But in normal mode not even one signal column is higher).. But if I turn 3g on, it starts to show one signal bar. I don’t understand anything whats happening. With my card, nothing as always.

          •  
            Wolverine3 years, 5 months ago

            -113 is very bad signal-strength (Almost no signals). You tried dialing *3001#12345#* on your friends (Who have no issue) iPhone? This confirms that your iPhone is not unlocked using Ultrasn0w or even if it is, its not properly installed. Try to install Ultrasn0w 1.2.3 using this method http://bit.ly/eQgshw

            iphone3 years, 5 months ago

            Wow, something strange. Location: /var/root/Media/Cydia/AutoInstall it should be like this, but Media folder is empty, so I should create those folders (Cydia and AutoInstall) myself?

          •  
            Wolverine3 years, 5 months ago

            Yep! You need to create them manually!

          •  
            iphone3 years, 5 months ago

            Oh and actually I can’t rename these folders, so maybe something is wrong before this? But Cydia is in my iPhone and it works.

          •  
            Wolverine3 years, 5 months ago

            To rename, click on a folder and then press F2 key :)

          •  
            iphone3 years, 5 months ago

            Sorry for so many comments, I am just so impatient about this thing. The things is that I found out, I created Cydia and AutoInstall folders and put to the right place, but nothing changed again. But I don’t know how should be after reboot, because after reboot in iPhone Explorer ultrasn0w.deb file is gone. But I turned on Cydia and there was shown that ultras0w is installed. I am so tired of trying, soon I will have no hope :)

          •  
            Wolverine3 years, 5 months ago

            Yup once Ultrasn0w is installed, the DEB should be gone after restart.

            Downgrade to iOS 4.1 using this guide http://bit.ly/kBIP4E

          •  
            iphone3 years, 5 months ago

            I get an error 1015.

          •  
            iphone3 years, 5 months ago

            Ok finally I fixed that error, downgrading to 4.1 was successful, but, the same “No Service” :((

          •  
            Wolverine3 years, 5 months ago

            If you are still getting No Service on:
            1. iPhone 3GS with iPad bb 06.15.00
            2. iOS 4.1 [Hacktivated and Jailbroken]
            3. After installing Ultrasn0w 1.2.3 and rebooting your iPhone

            It means there is no issue on the software end. Either your baseband is not 06.15.00 or it is a hardware failure which might include your SIM card as well. Another possibility is that you tried to upgrade your factory unlocked iPhone 3GS to iPad bb.

          •  
            iphone3 years, 5 months ago

            Now I have started to think, that I have upgraded my iPhone, but it was factory unlocked :( But what can I do if it it like that?

          •  
            Wolverine3 years, 5 months ago

            Can you tell me your model number written in-front of Model in Settings -> General -> About?

          •  
            iphone3 years, 5 months ago

            Model: MC131B

          •  
            Wolverine3 years, 5 months ago

            Shoot http://bit.ly/k1RkEK You did what i was thinking. It was factory unlocked model and there was no need to upgrade its baseband to iPad baseband. In either case, it should still work ideally.

          •  
            iphone3 years, 5 months ago

            What should I do now? Is it possible to fix that? :(

          •  
            iphone3 years, 5 months ago

            And now on iOS 4.1 battery is very bad.. So you don’t know any other solutions? :( And it will be hard to sell it..

          •  
            Wolverine3 years, 5 months ago

            Activate it using SAM http://bit.ly/kRl3Qw

          •  
            iphone3 years, 5 months ago

            What’s next? Because as always, nothing changed, the same No Service.
            1. I used SAM on iOS 4.1, maybe I should go back to 4.3.3 again (If yes, using Tinyumbrella or with sn0wbreeze)?
            2. “After syncing and backing up your iPhone, iTunes will throw error 1651. Just ignore this message.” – I didn’t get this error.
            3. “If you see ActivationState as WildcardActivated, thats it! Your done!” – This was ok. But I was stuck on “9. Thats it. Plug your iPhone to your PC or Mac via USB cable and launch iTunes. You will see the following screen in iTunes:” – after some time of waiting, I disconnected iPhone, then connected again and it started sync.
            I hope I described situation clear :)
            P.S. Man, thank You for you help, anyway, if it will work or not, I will not forget that!
            And I hope you have more ideas :(

          •  
            Wolverine3 years, 5 months ago

            1. Yep you can restore iOS 4.3.3 custom IPSW made with Sn0wbreeze at any time. You do not need SHSH blobs, so no need to use TinyUmbrella
            2. iTunes try to find legit certs for your unofficial carrier which technically is not possible as the SIM card in your iPhone is not official one
            3. You see ActivationState as WildcardActivated or not?

          •  
            iphone3 years, 5 months ago

            Answer to 3: Yes, I see WildcardActivated.
            P.S. I forgot to mention and I don’t know if it is important, but when I use sn0wbreeze, I choose “Hactivation” function (Because otherwise I just can do emergency call)

          •  
            Wolverine3 years, 5 months ago

            Yesh when you create a custom IPSW, choose hacktivation as you rely on an unlock.

          •  
            iphone3 years, 5 months ago

            And after jailbreak, what I should do first: unlock or use SAM?

          •  
            Wolverine3 years, 5 months ago

            It doesn’t matter. I use SAM first and them unlock my iPhone.

          •  
            iphone3 years, 5 months ago

            I have done everything, but the same “No Service”.. (When I try to choose network operator manually, I get “restricted network” error – but it was all the time like that, I just remembered that, maybe it is not important)

          •  
            Wolverine3 years, 5 months ago

            So you can see all carriers under Settings -> Carrier option? If this is the case then it means your iPhone is 100% unlocked and the issue is with your iPhone HW or SIM card. Try to change your SIM or SIM tray.

          •  
            iphone3 years, 5 months ago

            Yeah I can see carriers list, but as I said if I press on my carrier I get “Restricted Network” error. I don’t think it is a sim problem, because I tried few sims, and always the same. Sim tray? Hm.. But how it could make sense? It is not broken, and it was working in Lithuania and after few hours when I came back to Denmark it started not to work? Maybe it funny idea, but could plane do some changes? On the airplane all the time was turned airplane mode, and I was listening to music all the flight..

          •  
            Wolverine3 years, 5 months ago

            Lol. No Airplane mode should not be the issue. Get the SIM of any network you see in Settings -> Carrier and try it.

          •  
            iphone3 years, 5 months ago

            All the cards (mine too) which I tried is from the list of operators. And few minutes ago I tried “3” DK card, with it I even got a message “Unable to load network list”, but with others cards when I got carrier list, it is on the list..

          •  
            iphone3 years, 5 months ago

            No more ideas? :(

          •  
            Wolverine3 years, 5 months ago

            Take your iPhone to the nearest Apple store.

          •  
            iphone3 years, 5 months ago

            And…? But it’s without warranty anymore.. And anyway I think they would not do anything when they will see that there is iPad baseband?

          •  
            Wolverine3 years, 5 months ago

            Lol. Yep warranty is voided. I think you should sell it to someone.

          •  
            iphone3 years, 5 months ago

            Yeah, I am trying, but no success yet, because in Denmark people doesn’t want to do anything more when they buy something, so it is hard to tel that it is easy to “unlock” :D But it is interesting why it is happening, I called for few people, who has iPhone services here, and one of them said that he has two iPhones with the same situation and he has no idea too..

          •  
            Wolverine3 years, 5 months ago

            Ask those persons that you also upgraded the baseband of your factory unlocked iPhones :D Then they will get an idea of the problem :D

          •  
            iphone3 years, 5 months ago

            I said that, but they said they have no idea :D But you think it is not possible to make it working again after this? :D

          •  
            Wolverine3 years, 5 months ago

            I don’t think so because you made a HW mistake by upgrading bb of your factory unlocked iPhone. You can still take or send it back to your country and see if it works.

          •  
            iphone3 years, 5 months ago

            So what about technical things then, what part should be changed? (If it is possible)

            P.S. Tomorrow I am going to buy another phone and I don’t want to do mistakes again :D As I understood the guy who is selling it is not an expert in iPhone stuff, the baseband should be the same as mine was (05.16.02), and he updated to 4.3.3. So if there will be no Cydia and ultrasn0w it should be factory unlocked (of course I will check few different sims)? And of course I will do jailbreak, so which I should use better: sn0wbreeze or redsn0w?

          •  
            Wolverine3 years, 5 months ago

            Redsn0w as the baseband is already upto date.

          •  
            iphone3 years, 5 months ago

            But you don’t know which technical (HW) parts should be changed to make my iPhone working again?

          •  
            Wolverine3 years, 5 months ago

            Nops. Sorry for that. May be the bb chip which can not be changed.

          •  
            iphone3 years, 5 months ago

            And what would happen if I would try to jailbreak my “No Service” iPhone with redsn0w?

          •  
            Wolverine3 years, 5 months ago

            You cant do that as it is on iPad baseband. You can not restore stock IPSW on iPhone 3GS with iPad baseband.

          •  
            iPhone3 years, 5 months ago

            Hey again. Finally I bought another iPhones 3GS (32GB), it is factory unlocked with 05.16.02 on iOS 4.3.3. I asked you once, but you didn’t say which is BETTER for jailbreaking: sn0wbreeze or redsn0w? And do I need to choose “hactivate” function when I will do jailbreak?

          •  
            Wolverine3 years, 5 months ago

            Nops, if it is factory unlocked, you do not need to hacktivate. As you have latest baseband, so you can use Redsn0w 0.9.6RC16 http://bit.ly/iHqdFZ. Follow this guide http://bit.ly/iHqdFZ

          •  
            iPhone3 years, 5 months ago

            And for example if I will jailbreak it, but later on I will want to decline jailbreaking, so if it is factory unlocked, I will be able to do “Restore” on iTunes and it will be not jailbreak’ed again? I hope you understood what I mean :D

          •  
            Wolverine3 years, 5 months ago

            You can jailbreak and un-jailbreak a factory unlocked iPhone at any time BUT do not upgrade its baseband to iPad baseband. Once you have factory unlocked iPhone, you should not use custom IPSWs because they are only for jailbreaking your iPhone while preserving its current baseband.

          •  
            iPhone3 years, 5 months ago

            So what IPSW I should use?

          •  
            Wolverine3 years, 5 months ago

            Use stock iOS 4.3.3 IPSW. Everything is mentioned in a Redsn0w guide i told you.

          •  
            Wolverine3 years, 5 months ago

            1. Put another unofficial SIM card in your iPhone. Your iPhone should pick signals
            2. What is your iPhone model number? Settings -> General -> About

          •  
            iPhone3 years, 5 months ago

            Yeah, help is free, but I would love to help you too, and maybe I know how :)

            1. I tried few different cards, they are all working.
            2. Model number: MC133KN

          •  
            Wolverine3 years, 5 months ago

            From the model number, the phone might be locked to Netcom in Norway but later someone might have paid Netcom to finish the contract and make this iPhone factory unlocked. If you have tried diff SIMs, it should work after jailbreak. What is the current firmware version?

          •  
            iPhone3 years, 5 months ago

            Hmm strange, but it is possible.. It is 4.3.3 and I don’t see any Cydia in it..

          •  
            Wolverine3 years, 5 months ago

            To be on the safe side, do not restore it to stock firmware again. Instead, just follow this guide http://bit.ly/lAi8at and skip step 1, 2, 3 and 4.

          •  
            iPhone3 years, 5 months ago

            And if I will skip these steps, after jailbreak my phone will be as a new one anyway (I mean there will be not content)? Because now there is a lot of stuff from old owner, which I don’t need.

          •  
            Wolverine3 years, 5 months ago

            Nops, the stuff will remain until you restore the iPhone. Final choice is urz :)

          •  
            iPhone3 years, 5 months ago

            But maybe there is another way to delete all data? :)

            I can do this and feel safe even if it is not factory unlocked? :D Sorry for so stupid questions, but after that iPhone I don’t want to do mistakes again :D

          •  
            Wolverine3 years, 5 months ago

            Lol. Choosing this option means you are restoring your iPhone without connecting it to iTunes. It will just remove everything from your iPhone as if it is freshly restored.

          •  
            iPhone3 years, 5 months ago

            I have done “Reset All Settings” but all content is still here, messages, contacts..

          •  
            Wolverine3 years, 5 months ago

            Are you still getting signals? If yes then you can restore to stock iOS 4.3.3 IPSW safely. Also upload the screenshot of your Settings -> About screen on http://imgur.com/

          •  
            iPhone3 years, 5 months ago

            Yes, everything is working. http://imgur.com/MpyMV

          •  
            Wolverine3 years, 5 months ago

            You needed to show me baseband (Modem Firmware), Model and Version in that screenshot :P Anyways, you can just use Redsn0w 0.9.6RC16. Hopefully you won’t run into any issue UNTIL you do not accidentally upgrade your baseband to iPad baseband :)

          •  
            iPhone3 years, 5 months ago

            http://imgur.com/dcAHE :D Yeah, and I am very scared to damage this one too, but I want to jailbreak, because there is no point to have unjailbreaked iPhone :D

          •  
            Wolverine3 years, 5 months ago

            Ahh! It means you are in bad signal coverage. If iPhone is not unlocked, it will never show carrier name. Dial *3001#12345#* and tell me your signal-strength in dBs

          •  
            iphone3 years, 5 months ago

            With my card it shows nothing (Just the same “No Service”, and now I can’t try another card, just later. But I want to explain more about my situation. I have bought this iPhone in Lithuania, I tried it with few different cards, everything worked perfectly. But the same day when I bought it, I came to Denmark after my holidays, because I am studying here. I have put my danish card “Lebara” and it was not working. Then I tried Telia DK, it started to show operator name, bu nothing more. I called to Lebara, they said I need to update my iOS, so then I did this, the result is – “No Service”. In Settings > General > About, by network it show “Not Available”, but it writes carrier name anyway with all cards. I don’t understand whats happening with it.

          •  
            Wolverine3 years, 5 months ago

            If you have iPhone 3GS with iPad baseband and its unlocked on iOS 4.3.3 using Ultrasn0w 1.2.3, then every carrier SIM should ideally work on your iPhone. Have you tried restoring iOS 4.3.3 custom IPSW again and then unlocking with Ultrasn0w 1.2.3? This will clear out all confusions (If there is any issue in your iPhone)

            And I forgot to tell, my friend, who is living together with me, is using iPhone with the same Lebara operator, and he has no problem. So I don’t think that it is a problem with signal.

            What do you mean about restoring custom IPSW? I was doing exactly everything like it was written in your guides of sn0wbreeze 2.7. I was updating firmware with this file “iPhone2,1_4.3.3_8J2_Restore”. So as I said, none of carriers are working, just one of them show operator name, others – no.

            Oh! You restored stock IPSW instead of custom IPSW.

            Stock IPSW name: iPhone2,1_4.3.3_8J2_Restore.ipsw
            Custom IPSW name: iPhone2,1_4.3.3_8J2_Custom_Restore.ipsw
