    •

      I’m afraid there is no unlock solution for that baseband now! Your best bet is to try out those online unlock services, although you do need to take caution.

    Hi..I recently restored my iphone 3G. It got locked. I unlocked it with snowbreeze for iOS 4.2.1The phone appears to work well expect that it can’t make calls or send messages. It shows a network bar. But doesn’t identify the network carrier. Also, in the general settings, it shows “not available” fo the network tab. I tried unlocking it again but couldn’t solve the problem. Someone please give me a solution. I don’t want to use it as an iPod forever….

    Thanks for your guidance and suggestions
    I worked on h/w rf pwr o/p stage and now I am using it on 3G and 2g modes without any network specific problem

    The only problem remains is occassional auto dfu mode – from which I exits by hard resetting – please guide how to fix

    Thanks again

      Pramod3 years ago

      You did not restore your device using a saved SHSH for the particular iOS that your currently running. Running TU at the background to complete the restore will only force install the iOS onto your device w/o any SHSH blobs which is not the right way. Read this http://bit.ly/oKCpYX.

    Fine, I just now tried vodfone in 2G mode and is working fine /therefore is there chance for hardware problem
    Is the baseband software corrupted? Any clue to fix?

      More of a SIM specific issue is what I can see although I still do not rule out the possibility of an h/w issue either.

    Guidance is fine and followed and done it on itunes 10.4.0.1
    the set is jailbroken and PARTIALLY unlocked – it recieves 3g netwok of bsnl and reliance but no 2g networks / when on 3g every function(call/surf/etc) is fine

    plsease let me know whether it due itunes 10.4… Or due to any other error
    and guide to rectify it

    •  
      Pramod3 years ago

      Its definitely an h/w issue & I believe that this was always the case even before the update from iTunes. Also, its got nothing to do with the version of iTunes that you have used for the restore.

  •  
    sandy3 years, 1 month ago

    I have iPod touch 2g.

    I have followed all the steps in this guide and everything went well.
    After restoring with the custom ipsw, in this guide, it mentioned iPod/iPhone will restart automatically, but my iPod did not restart and I waited for 10 mins and I tried to power on. Now it doesn’t switch on nor can I see anything on my screen.

    Please help!!!

      Did you by any chance have TU running at the background to initiate the restore?

    Tiesto_83 years, 1 month ago

    I already set my phone to DFU mode but iTunes could not detect my phone.. It just says “iTunes could not connect iPhone because there was no network connection”.. Do I have to connect to the internet to jailbreak my phone? I currently do not have a connection at home at the moment..

    •  
      Pramod3 years, 1 month ago

      Well, Yes ofcourse !! If your going to restore your device, you definitely need to be connected to the internet for iTunes to connect to the Apple servers. For running Sn0wbreeze, you need not.

    Hi there,

    I understand the risk of upgrading the bb, thus i decided not to do it….

    but, is my ip3G actually factory unlock??? i don understand why after i jb it with snowbreeze, is lock, but when i restore back to 4.2.1 original is unlock again???

    so if i decided not to upgrade the bb, i have to wait if there will be a new software to unlock my ip3G if i jb with snowbreeze 2.2???

    thanks

    •  
      Pramod3 years, 1 month ago

      No. It never was factory unlocked right from the beginning. It was always locked to your UK carrier right from the beginning. Also, its not Sn0wbreeze, but its the update from iTunes to iOS 4.2.1 which costed you your ability to unlock the iP3G. There won’t be any unlock for the 05.15.xx – 05.16.xx. The people who are working behind the unlocks have already confirmed that.

    Chris Lim3 years, 1 month ago

    Hi there,

    i tot that i have reply u, but when i check this morning, my post wasnt there….

    neway, my ip3G is definitely unlock as i have try it on a few sim card in my country….this ip3G was locked to a UK carrier O2 and i did the unlock couples yrs back…and now i reside in Malaysia….no prob using it on any sim card and upgraded to 4.2.1 and still can use it with my sim card, just tat i lost the jb….

    like i have mention, after i jb with snowbreeze 2.2, the jb was successful but i cant use it with my carrier now or any other from my country….it shows 1 bar on the service bar, but i cant call out or receive calls….when i downloaded ultrasnow, the bar change to searching….after i restore to the original 4.2.1 with tinyumbrella and ireb, i have no prob using any of the sim card at all…strange???

    so, is my phone factory unlock???? any way of jailbreaking it???

    additional info, i install viber on my iphone, and i am stuck at the continue button, but when i use my sim card on my frens iphone, no prb getting the access code….not sure is it bcoz of the unlock or the problem with my iphone ios, but surely not the carrier prob….

    i have an ip3G, ios 4.2.1 and bb 05.15.04….

    thanks for your help…appreciate it…

    •  
      Pramod3 years, 1 month ago

      You are more clear with details now than your earlier post.
      Alright, so by updating / restoring your device via iTunes, you have lost both your jailbreak & unlock.
      Follow this guide here http://bit.ly/lccwoE & update your BB to the iPad’s BB first & only then will you be able to unlock your device. Make sure that your aware of the risks involved in updating your BB to the iPad’s BB first (Google it) & proceed ONLY if you wish to.
      Do not tick the Install Cydia option again from Redsn0w. You are already jailbroken via Sn0wbreeze.

    Hi there,

    I have an iphone 3G firmware 4.2.1 baseband 05.15.04….i jailbreak and unlock it when it was on ios 4.1….then i accidentally upgraded it to 4.2.1 with 05.15.04 baseband bout year back…and i thought it will re-lock back to the original carrier but thankfully it did not but i lost the jailbreak….

    i did not jailbreak it again as it cost quite a lot to jailbreak it thru mobile vendor in my country….but recently i realise that there is so much help jailbreaking it online, therefore i give it a try….

    here is the problem, i try jailbreaking it with snowbreeze 2.2 and i succeeded, but i cant unlock it with ultrasnow bcoz of the bb version….i thought i was deadmeat and i cant use it with my carrier now….but when i restore it back to original 4.2.1 firmware using tinyumbrella and ireb, i was able to use it again with my carrier now….

    my question is, my phone now is unlock, is there any way that i can jialbreak it and unlock it using snowbreeze or other jb software???

    i wrote an email to the previous lock carrier about unlocking my phone as my contract with them has ended, and they confirmed me that the iphone is permanently unlock….how come that i jb it with snowbreeze 2.2, is lock again and when i restore it back to original 4.2.1 and it is unlock….i’m confused…is my phone now still a locked version or is it unlock???

    thanks in advance.

    •  
      Pramod3 years, 1 month ago

      Currently, you haven’t actually UNLOCKED your device at all. Unlocking means that you will now be able to use SIMs other than your official carrier SIM to which your iPhone was actually locked to. So, to confirm, pop in 2-3 different SIMs belonging to different carriers (other than the official SIM ofcourse) & see if your iP3G is actually able to pick up their corresponding network signals for each & every SIM. If yes, then you are definitely factory unlocked & if not, your still locked to your previous carrier. Confirm the same & get back to me with your findings.

    Hi, I have Iphone 3G (Version 4.2.1(8C148), Modem Firmware 06.15.00) and not so proficient with unlocking thing. The phone works well in every department but Wifi is a problem. its not working at all. Could u please help me with stepwise procedure to correct it. Thanks in advance

    •  
      Pramod3 years, 2 months ago

      Is it greyed out by any chance or are you not able to grab any nearby hotspots? Define your problem. If this Wi-Fi issue was existing prior to the unlock, then I’m afraid its a hardware issue. But, you can always try to do a fresh install of the iOS 4.2.1 & see if your Wi-Fi issue gets corrected or not.

    •  
      Pramod3 years, 2 months ago

      Have you made sure that you have created an IPSW for your device model only? The error mentions that your using an iOS version that is actually meant for a different iPhone model altogether.

    so is there no way that i can downgrade it without shsh blobs………..btw how do u find out if u even do have blobs because mmy iphone was secondhand and from a friend so i dont know and he dosent remember.
    ihave never installed ios 4.3.3. however i have priorly installed ios 4.0.2 and is it possible that the shsh blobs for that is saved

    •  
      Pramod3 years, 2 months ago

      Jailbreak your device first. Then, fire up Cydia & have a look here http://bit.ly/qS5bjW. If you see any iOS versions listed here, then these are the versions for which your having an SHSH blob saved & to which you can downgrade to as well.

    •  
      Pramod3 years, 2 months ago

      Only if you have saved an SHSH blob for iOS 4.3.3 either using Cydia/TU will you be able to perform a downgrade. So make sure you have one first.

    •  
      Pramod3 years, 2 months ago

      It will not. iP3G is the least that you need to worry about when it comes to restores. Make sure that you have infact started the restore process only after you have put your device into a pwned DFU mode & that the custom IPSW has been created without any errors.

    Hi Wolverine

    I have recently jailbroken iPhome 3G using Snowbreeze 2.2. I had initially used redsn0w to upgrade the bb to ipad in order to unlock.

    After successfully using snowbreeze my iphone no longer receives network or wifi. i have tried resetting the network settings but no joy.

    I had selected the option to download ultrasnow during installing the custom ipsw 4.2.1 using snowbreeze.

    Any idea or suggestions would be welcome.

    Regards
    Tee

    •  
      Pramod3 years, 2 months ago

      Well, install Ultrasn0w once again but this time use the Wi-Fi/offline methods to do so. Looks like the Ultrasn0w install hasn’t gone through with success via Sn0wbreeze.

      If you really don’t know how to do any of the things I have suggested you in very simple steps, then please refrain from asking anything here. For nearly 4 days I have been giving you suggestions on how to get certain things done and you simply do not want to follow them. Sometime back you told me that your stuck in the Emergency Call screen & now your not. If you have solved that/any issue already, then why don’t you update your comment here just like everyone else? Why aren’t you sticking to a certain issue & wait for my solution? You don’t want to follow my steps but you also want to experiment things on your on. This leads to alot of confusion.
      Also, this is the second time your asking me about the iOS 3.1.3 custom restore for which I have already replied 3 days ago here. Why won’t you read your earlier comments to which I had already answered ?
      If you want to solve them on your own, your more than welcome to use the Search bar to search across Jaxov topics at the top.

    •  
      Pramod3 years, 3 months ago

      Jailbreak your device then using Redsn0w. Or else if you have the official SIM card that came locked to your iPhone or any SIM card belonging to an iPhone of the same carrier, put it in and connect it to iTunes.

      If your looking forward to downloading the custom iOS 3.1.3 IPSW, get it from here http://bit.ly/ivIkMg and restore in a Pwned DFU state.

      There is nothing like easy jailbreaking, unless you are on iOS 4.3.3 and use JBMe3. :D

    hi guys

    how are you doing? i have gotten an Iphone (version 4.2.1 (8C148) / Carrier AT&T 9.0 / Model MB046LL / Modem Firmware 05.15.14) as a gift a year ago; i put a Moroccan SIM card in it and it does not work!(SIMcards of the 3 operators) i want so much to use it and benifit from its services but how can i do that? how can i unlock my Iphone and use a Moroccan SIM card in it? i checked the network and it says “SIM not provisioned”, is there any hope to use it in Morocco? and please is there any free way to unlock it because i can not buy any software and anything through the net as i am looking for a free way to unlock it. i appreciate so much the time and energy of writing and reading this as i appreciate your help so much.

    thanks a lot in advance!

    Yes i used it……

    •  
      Pramod3 years, 3 months ago

      iOS 4.2.1 on an iP3G does infact drain the battery out of your iPhone. The only thing you can do right now is to revert back to a 3.1.3 version of the iOS. That should solve your battery issues.

  •  
    Atif3 years, 3 months ago

    B4 I do that I want to ask u….
    About battery drainage…..!
    Da battery is draing vry vry fast….
    Is it bcz of iOS 4.2.1 if so shud Install previous versions….??

    •  
      Pramod3 years, 3 months ago

      Your asking me the same query again. I have replied to you here. Did you use SAM yet?

  •  
    Atif3 years, 3 months ago

    The prob is usually cOming up when I press da view button after recieving a txt and wen I open something from the multitasking tab at the bottom of da screen….

    •  
      Pramod3 years, 3 months ago

      Possibly because of some theming utility or themes that you may have installed using Cydia. Could be many reasons. A clean & fresh installation of the iOS will resolve such issues.

    hi, I followed the steps and all and restored me iphone 3g when the screen was green to the one i just got created.
    i have 1 problem. Why wont my Iphone start up? I keep turning it on but all i get is the apple LOGO.

    Like when i restarted it the apple logo has been up and it hasn’t loaded for almost an hour. Please Help.

    •  
      Pramod3 years, 3 months ago

      Your stuck in a RecoveryLoop. You need to always use a custom IPSW to restore your iP3G. Seems like you have instead used Apple’s stock IPSW.

  •  
    Atif3 years, 3 months ago

    the springboard is either crashing or restarting again and again

    •  
      Pramod3 years, 3 months ago

      After doing what? Please explain.

  •  
    suman3 years, 3 months ago

    Thanks for your help. All these steps works like a charm. I was getting a log of 14 errors. If you are getting a lot of error 14 than you should do this (this is what helped me)

    Uninstall itunes from your PC will all other stuffs like Bonjour, Apple mobile device service, quicktime etc.

    Run ccleaner to clean all that temp files created by intunes.

    Restart your computer.

    Reinstall itunes and follow the step by step instruction giveb above.

    This is how I solved my problem.

    Atif3 years, 3 months ago

    One last thing….
    What will turning off SSH in SBSettings do…??

    •  
      Pramod3 years, 3 months ago

      SSH is Secure SHell connectivity. Its basically a terminal access to your iPhone. Turning OFF SSH will disable this functionality which is not that important.

  •  
    Atif3 years, 3 months ago

    sorry…..
    will i have to sync again…..???
    will it delete stuf….??

    •  
      Pramod3 years, 3 months ago

      No, it’ll not delete anything from your iPhone. So no worries.

  •  
    Atif3 years, 3 months ago

    how will SAM help me or in other words how is it good for me….??

    •  
      Pramod3 years, 3 months ago

      Did you read the article? Read the article. It explains you why its necessary in the first paragraph itself. SAM will resolve your current battery drainage issue that your having on your iP3G.

  •  
    Atif3 years, 3 months ago

    the link u gave is an article on….
    How to Activate iPhone 4/3GS on iOS 4.3.3 Using SAM?
    but i m using 3g and ios 4.2.1…

    •  
      Pramod3 years, 3 months ago

      It works for any iOS/iPhone versions. Its all the same.

  •  
    Atif3 years, 3 months ago

    what about ultrasnow……??
    does it not activate…..?

    •  
      Pramod3 years, 3 months ago

      Ultrasn0w only unlocks your iPhone. SAM & Ultrasn0w are 2 different things totally unrelated to each other.

  •  
    Atif3 years, 3 months ago

    the speed prob settled down…..
    its working great….
    just 1 prob da batter is draining too much is this because i istalled
    barrel and SBSettings from cydia…….??

    •  
      Pramod3 years, 3 months ago

      Yes, its definitely possible because of Barrel. SBSettings may not take up as much juice out of your battery. Make sure that you have also officially activated your iPhone using SAM as Sn0wBreeze will only Hacktivate your iPhone. Follow this guide http://bit.ly/mDpDwr.

  •  
    Atif3 years, 3 months ago

    HEY….
    MY IPHONE,…. IS LIKE DEAD…..
    ITS BECOME TOO SLOW AFTER I INSTALLED 4.2.1 !!
    IS IT MAYBE BECAUSE I RESTORED IT FROM A BACKUP…..??

    •  
      Pramod3 years, 3 months ago

      Possible, but can’t be sure at the same time. iOS 4.2.1 is never a laggy version unless your having an iP3G. It definitely makes the iP3G cough up.

    Hi Guys – I’d be really grateful for any help.
    I have jaibroken an iphone 3G (4.2.1) using sn0breeze and using the correct 2,1,4.21 IPSW for it to work on. I selected Hactivated and “Simple” option.
    After much effort (? usb issues) the jailbreak has taken and firmware updated. However now I have no WIFI so Cydia cannot load.
    I can access the files using iPhoneBrowser. I beleive there have been issues using sn0wbreeze 2.1 on the 4.2.1 OS on the 3G but nowhere can I find a solution to getting wifi working again. I have removed all network setting and repeatadly re-booted – all to no avail.
    The baseband (modem firmware) is now 05.15.04
    Anyone got any ideas?
    Thanks in advance.

    •  
      Pramod3 years, 3 months ago

      Is your Wi-FI option by any chance greyed out? Or are you not having access to a Wi-Fi signal itself in the first place? Also, you should know that if you rely on an unlock, its not possible on your current BB.

  •  
    suman3 years, 3 months ago

    I have been trying to restore my iphone 3G with custom FW 4.2.1 and I have followed all steps correctly. But when I try to restore via itunes I always get error number 14.

    Any advices???

    I am stuck with apple logo and then connect to itunes images in my iphone 3G. The itunes always says that my phone is in recovery mode.

    •  
      Pramod3 years, 3 months ago

      Have you made sure that you have put your iPhone in a Pwned DFU mode and not just in a normal DFU? Error 14 seems to be more of an USB issue. Try the same restore procedure by plugging your iPhone onto a different computer/laptop & also try uninstalling an reinstalling iTunes to the latest version.

    Wunn3 years, 3 months ago

    @pramod

    It solved, I used snowbreeze 2.2.1 and it worked… the one provided on this website didn’t recog my ipsw :/

    Hi Wolverine,

    I need your help. I have my iphone 3g in 4.2.1 with baseband 6.15 however its not detecting any wifi. Can you please help me out?

    •  
      Pramod3 years, 4 months ago

      Make sure your Wi-Fi is discoverable and that its not hidden. Use a different device like an another mobile handset to see if its able to detect the Wi-Fi or not.

      •  
        Allan3 years, 4 months ago

        Yup, all those are ok. I got a few pcs and other phones that are able to connect thru my wifi. it doesnt only happen on my wifi but anywhere. I think the problem is with the phone itself. Please help me.

        •  
          Pramod3 years, 4 months ago

          Yes, I do think the same as well. Has it been bothering you from the start? I hope not. Well, what I can suggest you is to restore your device and try once again, since its not a problem that you had from the start. Restore to a Custom 4.2.1 FW to see if it solves your issue. Good Luck.

    Phil3 years, 4 months ago

    Hi there,
    I have bought a 2nd hand iphone 3g 16gb, it is on 4.2.1 and 06.15. I have used Redsnow to jailbreak and installed ultrasnow through cydia (no wifi way) and my iphone 3g goes but always has “No Service”. No matter how much i look on the internet, i cannot find out how to unlock to vodafone, currently on telstra i think. Is there any way possible to unlock to vodafone aus? I tried resetting, put on aeroplane more then off, reset network settings, rung up telstra to unlock but i cannot restore through itunes unless to custom ispw. I am almost about to give up. Know of any way??
    Cheers, Phil

    •  
      Pramod3 years, 4 months ago

      Phil, try popping in a different SIM of another carrier into your iPhone and tell me how it behaves. Usually, if it shows a No Service, it means that your unlock is good. Try it with a different SIM and let me know. :)

      •  
        Phil3 years, 4 months ago

        I have put in an optus sim card, still no service. Should i try another carrier??

        •  
          Phil3 years, 4 months ago

          Hi again, I loaded a Telstra sim and it had service, i reloaded my vodafone and it worked, but it only had 1 bar and lost signal very easily. I can only rarely get service even though i am centrally in the City. Any suggestions there?? Thanks for last comment this is the furtherest i have been with it :D

          •  
            Pramod3 years, 4 months ago

            Okies, so seems like the Ultrasn0w works just fine, but the SIM is still causing the issue here. Telstra seems to work fine here right? Switch off the 3G services and see if you can get a proper GSM signal on your iPhone. Since Telstra works just fine, the problem is with the Vodafone SIM.

          •  
            Phil3 years, 4 months ago

            Im not sure, i was hoping to stay with vodafone?? the telstra SIM only had one bar when i inserted, and thats when i inserted the vodafone one it worked straight away too. The SIM works fine in other phones, just not this one

          •  
            Pramod3 years, 4 months ago

            Hmmm, I wonder now. Well how about your try these 2 SIM’s in your friend’s iPhone and see how it behaves? That should confirm our doubt as to if its the iPhone or the SIM that’s causing this issue. Alternatively, pop into your iPhone his SIM as well. We have 2 scenarios here to confirm. Let me know. :)

    Hello, Wolverine
    I bought a used iPhone 4 with iOS 4.2.1 (8C148) and baseband 03.10.01, model (MC605NF) unlocked (I don’t know how to confirm), It has cydia not activated (white icon), and has no SHSH files..
    Is it possible to activate cydia for this iPhone?
    Thanks very much…

    •  
      Wolverine3 years, 5 months ago

      You mean unlock or activate? If you want to activate it, use SAM http://bit.ly/kRl3Qw and if you want to unlock it, use Gevey SIM. If it is factory unlocked, you do not need to activate or unlock it. From the model number, your iPhone can be locked to some carrier in France or Luxembourg

  •  
    Robert3 years, 5 months ago

    I don’t rely on a unlock I have even tried restoring using iTunes and letting iTunes download the file to restore still got same issue

    •  
      Wolverine3 years, 5 months ago

      You mean restoring stock IPSW also did not helped? Have you tried to hard-reset your iPhone? Press the Home+Power button until your iPhone restarts and then Apple logo logo appears on your screen.

      •  
        Robert3 years, 5 months ago

        No it did not help I have hard reset and also the battery has died if that counts as a hard reset ? Yes the restore ISpw restore from apple did not fix I always thought u could always restore to undo any jailbreak guess not

        •  
          Wolverine3 years, 5 months ago

          Ok. I just confirmed it from a friend who is into iPhone repairing. He said that this is issue with some units of iPods with malfunctioning WiFi chip. Even if you will restore or hard reset or soft reset your iPhone, after a day or two, you will still get this problem. Just go to nearest Apple store, they will happily give you a replacement.

          •

    Robert3 years, 5 months ago

    hey guys i need help in a bad way … i have 3 ipod touch 2G im new too this JB thing i have only done a 3GS using redsnow worked good as far as i can tell i had to get past the sim card activation screen as i dont have a sim card and am using it for a ipod. Question did redsnow unlock it for any carrier as well? more curious than anything

    ok back to the ipods these are all from my friends who asked me to JB all using 4.2.1 2 are MC models and one MB model …

    MB model redsnow worked perfect no issues

    then i go to the MC models (redsnow dont work )I used snowbreeze for 4.1 created a custom software and restored it using itunes
    it worked fine but after looking the wifi is grayed out ?
    i have restored to original but no luck even tried JB again same issue
    I was afraid to do the other MC because i did not want same issue. since then i found green poison and JB 4.2.1 on the last ipod but the other ipod is still grayed out no matter was OS or JB what do i do ? besides different JB and restoring to factory multiple times i have cleared network settings etc all other Ipods are working perfect no issue. Please someone help i am new to this.

    •  
      Wolverine3 years, 5 months ago

      Redsn0w always hacktivates the iPhone and NO it do not unlock your iPhone. To unlock your *unlockable* baseband, you must use Ultrasn0w 1.2.3. Back to the iPod whose Wi-Fi is grayed out, when you go to Settings -> General -> About -> Do you see Bluetooth and Wi-Fi address also grayed out?

      •  
        Robert3 years, 5 months ago

        No Bluetooth has an address its just the wifi that is grayed out … do you think a hardware issue because once you reload the apple 4.2.1 firmware shouldn’t it undo anything i did load custom firmware?

        •  
          Wolverine3 years, 5 months ago

          If Bluetooth address is 00:00:00:00:00:00 and Wi-Fi address is N/A then its a hardware failure http://i.imgur.com/YM8Du.jpg In your case, when you go to Settings -> Wifi -> ON, do you see Wi-Fi networks? or the entire Wi-Fi option is greyed out? What is your current baseband? Do you rely on an unlock? Also have you got iOS 4.2.1 or iOS 4.1 SHSH blobs?

          •  
            Robert3 years, 5 months ago

            It’s just a iPod touch 2g I don’t see a baseband ? The blue tooth option has a actual address not all 00 and the wifi is greyed out under settings won’t let u select it to even pick or search for a network I didn’t save any shsh those are basebands right? I read bout people saving them don’t know what they are thou .. I came from a Blackberry for 3 years So still learning this stuff

          •  
            Wolverine3 years, 5 months ago

            Nops, those are SHSH blobs are they are used to downgrade your firmware. Baseband is something else and it is solely related to unlocking only.

  •  
    Jason3 years, 5 months ago

    I have an iPhone 3GS with iOS 3.1.2 and baseband 5.11.07. Currently it is unlocked but it is tethered. Can I still upgrade the iOS to 4.2.1 or later while keeping my phone unlock (hopefully making it untethered) to use any carrier that I want? Upgrading to ipad’s bb 6.15.00 is not an option for me since I don’t want to lost my GPS functionality. Thanks for your help!

    •  
      Wolverine3 years, 5 months ago

      There is no need to upgrade to iPad bb. Just download Sn0wbreeze 2.2.1 from here http://bit.ly/lBrgjx and follow this guide http://bit.ly/hasi6C to jailbreak iOS 4.2.1 on your iPhone while preserving your current baseband. If you are a Mac user, use PwnageTool 4.2 http://bit.ly/g4eqGd

      •  
        Jason3 years, 5 months ago

        Thanks Wolverine, couple more questions

        1. Would you recommend me upgrading to iOS 4.3.3 since Sn0wbreeze 2.7.1 is out to support it? Or should I stay on 4.2.1?
        2. Should I save my SHSH Blobs before I do anything to my current unit? If so, which version of TinyUmbrella should I use? the latest?
        3. If I selected the Hacktivate option during the IPSW custom build process, do I still need to do the SAM procedure to activate my unit after jailbreak (Sn0wbreeze) and unlock (Ultrasn0w)?
        4. Do I need the install SSH option? In your Sn0wbreeze 2.2 guide, it is required, but in your Sn0wbreeze 2.7 guide, it is optional. Please clarify.
        5. If enable battery pct option is NOT checked during IPSW custom build process, will I still have that function on my unit?
        6. What is Animated Boot Logo Capability?

        Thanks again for your time.

        •  
          Wolverine3 years, 5 months ago

          1. Stay on iOS 4.2.1. iOS 4.3.3 is laggy and there are Ultrasn0w unlock issues
          2. Now you can only save iOS 4.3.3 SHSH blobs. Grab latest version of TU from here http://bit.ly/gDFJ0K
          3. SAM is always optional (For battery life and Push Notifications) but as you rely on an unlock, so you must hacktivate atleast
          4. Install SSH is always optional. You can install it later using Cydia -> OpenSSH
          5. To enable battery %age, you need to check that option. Otherwise you wont find it after JB
          6. Thats in only for iP4/3GS users on iOS 4.3.3 (Not sure about that)

          •  
            Jason3 years, 5 months ago

            Cool, thanks for the quick turnaround.

            I am still couple more confusions and hope you can help me clarify

            1. So if today I decided to go to iOS 4.2.1 and preserving my baseband of 5.11.07 as you suggested, what do I need to do to give me the ability to be able to revert my iOS to 3.1.2 if upgrade process goes bad? Since you said TU can only save iOS 4.3.3 SHSH blobs.

            2. Just to be clear, I will run SAM on top of hacktivate

            3. After I restore my 3gs using a custom IPSW for iOS 4.2.1, hacktivate and run SAM on it. I should be able to connect my unit to itune as normal and be able to backup/restore my text, contacts, etc and sync all my apps right? If not, what other steps am I missing?

            Thanks!

          •  
            Wolverine3 years, 5 months ago

            1. If you see iOS 3.1.2 SHSH blobs in TinyUmbrella, you can downgrade later. Else not possible.
            2. Yeah, you can use SAM on a hacktivated iPhone.
            3. I don’t think so it is possible to restore a backup of iOS 3.x.x on iOS 4.x.x. You can still confirm this with anyone else. However you can sync apps and contacts (But i don’t think backup will be able to restore on ur iDevice)

          •  
            Jason3 years, 5 months ago

            Great Thanks Wolverine!!

            In your Sn0wbreeze 2.2.1 for iOS 4.2.1 instruction, you listed to use iTune 10.1.2. Does that matter? or the latest iTune version would still work? If not, do you have a 10.1.2 copy that you can point me to?

            Similar question for Ultrasn0w, is there any specific version I need to use or the latest one would be able to unlock my unit with bb 5.11.07. And this Ultrasn0w unlock is untethered right?

            Thanks

        hi Wolverine
        i tried tinyumbrella which says it does not have shsh. Below is the log.

        04/18/2011 23:49:19.975 This device isn’t eligible for the requested build. 04/18/2011 23:49:19.991 CYDIA DOES NOT HAVE YOUR SHSH FOR iPhone4 4.2.1 (8C148) THERE IS NO WAY FOR YOU TO GET THEM. SORRY. YOU ARE JUST TOO LATE.

        Any help will be greatly appreciated
        Thanks
        Manu

          Sorry Manu but you are little late. You can never EVER restore stock or custom iOS 4.2.1 IPSW because you never saved its SHSH blobs for your iDevice when it was released.

    ok awesome, thanks alot for the help!
    really appreciate it :)

  •  
    Jaz3 years, 7 months ago

    thanks for the guide mate,
    just one quick question. When it says it upgrades your baseband, do you know what it upgrades it to?

    •  
      Wolverine3 years, 7 months ago

      Do not worry about that if you do not rely on unlock :)
      PS: It will upgrade your bb to 05.15.04 which you already have!

  •  
    Jaz3 years, 7 months ago

    yeah lol i didn’t preserve my baseband after all, just noticed that now :D

    the first time i tried sn0wbreeze 2.2 the jailbreak process failed. i got stuck in recovery mode and i did use a stock ipsw for 4.2.1 and i did infact update my bb :P
    though no problem i dont need an unlock as ive just restored my phone back to 3.1.3 using SHSH in TU and my sim card is recognized got full bars of reception!! so yeah no unlock needed which is pretty cool news.

    its weird though cause i did make a custom firmware in sn0wbreeze using stock 4.2.1, and i used the custom fw to restore in itunes. but i wasn’t getting any signal before, same sim same baseband and everything that im using now!
    dont really understand whats going on????

    right now i just want to upgrade the firmware to 4.2.1 with a JB.

    any recommendations?

    Thanks Wolverine

    •  
      Wolverine3 years, 7 months ago

      If you do not rely on unlock then GreenPois0n is the best choice for you. Restore stock iOS 4.2.1 IPSW and use GreenPois0n. Follow this guide

    hi Wolverine,

    i recently updated my iphone 3gs from fw3.1.3 to custom fw4.2.1 using sn0wbreeze 2.2
    everything went fine with the jailbreak except after adding yellowsn0w my phone will not get a signal. its just searching.
    and when i remove yellowsn0w it stays on 1 bar and i cant make or recieve calls.

    when its on 3.1.3 jb and unlocked i dont have a problem with the signal.
    i got an iphone 3gs on firmware 4.2.1 running baseband 05.15.04
    what can i do other than upgrading the bb to 6.15?
    i remember reading something about 6.15 being dodgy thats why ive stayed at 3.1.3 for so long to preserve my baseband.

    thanks

    •  
      Wolverine3 years, 7 months ago

      I don’t think you updated to custom IPSW, because your baseband is updated to 05.15.04 which signals that you restored the stock iOS 4.2.1 IPSW. The only solution to unlock your iPhone is to upgrade your baseband to iPad baseband. You can either use this guide or this guide.

    hamzzzz3 years, 7 months ago

    update….

    •  
      Wolverine3 years, 7 months ago

      Not now. But hopefully unlock will be out soon. Keep your fingers crossed.

  •  
    hamzzzz3 years, 7 months ago

    hello wolverine

    i am on the iphone 4 4.2.1 version with baseband 2.10.04….i already tried the greenpoison jb but i dont have the actual sim to activate phone…can i use snowbreeze to hactivate my phone? and also how can i unlock it as i intend to use some other sim with it…help will be greatly appreciated

    •  
      Wolverine3 years, 7 months ago

      Yes you can use Sn0wbreeze to hacktivate your iPhone but make sure you have iOS 4.2.1 SHSH blobs as SHSH blobs are must to restore iOS 4.2.1 custom IPSW. Unlock is not out but hopefully it will be released with in a month or so. Stay tuned!

    Hello Guys,

    I followed the steps, and was able to restore along with Cydia and ultrsnow installed. Unfortunately it does not pick up the tmobile carrier though it recognizes that the sim is present. Any help would be much appreciated. Vitals below:

    Iphone 3G
    Modem Firmware 06.15.00
    Tmobile Sim
    Network = Not Available
    Version 4.2.1 (8C148)
    Carrier = Not Available
    Model = MB046LL
    WI-FI Address,Bluetooth,IMEI, and ICCID all visible

    Thanks again for any assistance

    •  
      Wolverine3 years, 7 months ago

      Reboot is a must after Ultrasn0w unlock.

      •  
        Case3 years, 7 months ago

        Yes,

        I rebooted several times, and also reset network settings several times. I still have no wi-fi networks available and no carrier signal. When I insert the Tmobile sim ‘New Voice Mail’ appears’, but I cannot make a call.

        Regards,
        Case

    Hi,

    When i download my itunes (10.1.2) my firmware is already 4.1.2, so i need to download my firmware again in order to jailbreak?

    Praveen3 years, 8 months ago

    Hi guys,
    i have updated ios 4.0.1 to ios 4.2.1. The update went good. Have installed repo666.ultrasnow.com (cydia – manage – sources) package as well. but it does not detect the carrier signal. The strange thing is that it detects the sim and searches for the signal for a long time and says “No Service”. if i insert any sim it detects , search’s for the signal and says “NO Signal” and in “Settings -General- about -carrier – it shows “carrier 9.0″. Can some one help.

    •  
      Wolverine3 years, 8 months ago

      Can you tell me your baseband and iPhone model?

      •  
        Praveen3 years, 8 months ago

        it is 5.15.04. Today i tried with vodafone sim, it detects the same in “Settings -General- about -carrier – it shows “Vodafone” but still the same. searches for the signal and says “No signal”

        •  
          Wolverine3 years, 8 months ago

          Yes, you can unlock your iPhone. Do not do anything silly right now. Just follow these 3 steps below:
          1. Follow the step-by-step guide here to upgrade your iPhone 3GS/3G baseband to 06.15.00.
          2. Install Ultrasn0w 1.2 though Cydia
          3. Now your iPhone will catch signals of any carrier you want. Just need to put its SIM.

          Do reply if you have any questions or ask us at our Facebook fan page for more quick replies.

    •  
      Wolverine3 years, 8 months ago

      You cant unlock but you can jailbreak and hacktivate it using GreenPois0n tool (Win Guide | Mac Guide). As far as unlock it concerned, it will be released when iOS 4.3 final will be out.

    hey,
    i have iphone4 working on 4.2.1(8c148)
    and modern firmware 03.10.01
    is it okay to use sn0wbreeze on my device?
    the phone is currently unlcked, i’m using it as an itouch only,
    how do i sim unlock it?

    •  
      Wolverine3 years, 8 months ago

      You have the latest baseband. So there is no need to use Sn0wbreeze as it will be of no use. Use GreenPois0n (Win Guide | Mac Guide). As far as unlock it concerned, it will be released when iOS 4.3 final will be out.

    Thanks, I’ll let you know how it turns out.

    Rich3 years, 8 months ago

    I tried using sn0breeze 2.2 for my iPod Touch 3G, but iTunes told me that the firmware was uncompatible, it may have been the original 4.2.1 firmware I downloaded, anyways. Having already updated to 4.2.1 previously, like an idiot, I don’t think I can download the new version from iTunes anymore (which is why I originally downloaded what may have been an incompatable firmware in the first place). Right now my iPod is in PWNED DFU still and I’m not sure how I should handle it :(

    •  
      Wolverine3 years, 8 months ago

      Kindly use this iOS 4.2.1 IPSW for your iPod Touch 3G and jailbreak it with Sn0wbreeze 2.2 final using the above instructions.

    i’ve tried the new snowbreeze 2.2 and was succesfully jailbreak my iphone 3GS SU OS4.2.1 with BB 5.15.04.. but it seems my wifi is unable to search the network.. it is some weakness due to this JB? or i maybe i had something wrong with my JB? plzz share.. btw,now im downloading the “Ben Johnson” custom ipsw for Iphone 3GS activated to see if something good happen with my wifi.. becoz its really important to me, since iphone with bb 5.15.04 still cannot be unlock without upgrade it to 6.15 ipad baseband and still i cant do download through my iphone without any sim card or wifi. thx

    •  
      Wolverine3 years, 8 months ago

      Proceed at your own risk with Ben’s custom IPSWs. We recommend you to create your own one with Sn0wbreeze 2.2. If you have used the final version of Sn0wbreeze 2.2, it should solve the Wifi and iBooks related issues. Sn0wbreeze 2.2r1 is known to have some Wifi issues but they are fixed in the final version.
