How to unlock iPhone 3G / 3GS Baseband 05.14.02 & 05.15.04 using Redsn0w 0.9.6b5

By | December 4th, 2010



The redsn0w varient of the carrier unlock iPhone 3G & 3GS with baseband version 05.14.02 and 05.15.04 has been released which supports both Mac and Windows platforms. This version is much easier to use as it automatically updates your current baseband to the new version for iOS 4.2.1 while jailbreaking and hacktivating your device.

ultrasn0w iphone unlock How to unlock iPhone 3G / 3GS Baseband 05.14.02 & 05.15.04 using Redsn0w 0.9.6b5

We earlier released a guide for Mac users that enables them to create custom IPSW files using the PwnageTool. However Windows users are required to use this Redsn0w guide in order to jailbreak followed by unlocking of their device. This guide updates your baseband from 05.14.02 and 05.15.04 to modem firmware 06.15.00 which is unlockable now.

Warning:

Unlockers have been reporting mixed results about GPS functionality at 06.15.00.

  1. There is no way to come back down from 06.15, and there’s no hiding the baseband version from Apple. You’ll be voiding your warranty in a very obvious way.
  2. If some future baseband comes out with a critical fix, you won’t be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn’t update to it if you wanted to keep your unlock anyway).
  3. Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail).  You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).

If you’re alright with the above warnings from the iPhone Dev Team, you may proceed with this unlock procedure. Due to the GPS issues, it is recommended for those running unlocked devices on previous iOS version to stay away until the issue is resolved.

Procedure:

  • If you’re an iPhone 3G or iPhone 3GS (old-bootrom) users, you may update to the new firmware using iTunes. iPhone 3GS users are recommended to stay at iOS 4.1 until an untethered jailbreak for your device is available.
  • Once the new iOS is installed, download the redsn0w 0.9.6b6 and run the program.
  • Provide it with the IPSW of your current software IPSW and wait while it verifies.

  • Once the verification is complete, select “install iPad baseband”. The setup will now download the baseband 06.15.00 directly from Apple directly during installation, so make sure your internet is running.
  • Enter the device in DFU mode using the on-screen instructions. Once your device is in DFU, the redsn0w installer will take over and jailbreak and hacktivate your device.

  • Once the jailbreak is complete, fire up Cydia app from your iPhone, go to Manage tab, and select Sources. Now edit to Add the source http://repo.ultrasn0w.com and select Add Source. Cydia will g through a series of steps to update your sources.

  • Now go to the Search tab and look for ultrasn0w. Install this app which will unlock your device. You might have to restart your device before your carrier works.

  • Anonymous

    You’ll have to select “update iPad Baseband” during jailbreaking to update your baseband to 06.14.00 during jailbreaking. Then you can install ultrasn0w 1.2 to unlock the device. :)

    I am trying to unlock a new iPhone 3Gs firmware 4.2 and baseband 05.15. I have Windows XP computer.
    I seem to have a problem because my iPhone now is stuck onto the start screen, with the white apple logo and the prcessing circle sign!
    This is what I did:
    Got the redsn0w 0.9.6b6 and ran it. The production week of my iPhone should be 44, so flagged “new iPhone” in the procedure. Then I follwed the DFU mode correctly in fact the tethered part of the procedure worked and said “done”; i clicked “finish”.
    The i got the screen on the iPhone saying if was “Flashng Baseband” the blue processing bar stopped at halfway through and then the iPhone showed the black screen with apple plogo and little circle over it.
    It’s been sthck there for the last 5-10 minutes.

    What should I do?
    I have no idea of what I should do now and am worried I might ruin everything: please help!

  • Matteo

    I tired running redsn0w again; did the DFU thing, but then it gets stuck shortly after starting the tethered process.
    iPhone just turns on to the black screen with Apple logo and is stuck.
    I googled this problem and found: http://answers.yahoo.com/question/index?qid=20101205225645AABhE3D
    where someone sais: “you need a custom firmware made with pwnagetool. Remember you can never use stock firmware now that you have iPad baseband”. But I have no idea wht this means!
    Please help!

  • Matteo

    I’d restore but but my PC can’t see the iPhone anymore.

  • Anonymous

    Calm down Matteo. There is no unlock for 05.15.04, so you need to first update the baseband and their proceed. Follow this guide if you have a Mac and use PwnageTool.

  • Captdb2000

    I have the redsnow installed but there is no baseband option to choose.

  • Captdb2000

    It is a 3g. I cannot restore now because Apple gives me an error after I hit the restore button in itunes.

  • Captdb2000

    OK. I restored it. It was as simple as changing the USB to another port. It then recognised the iphone and I was able to restore it. I still cannot select ipad baseband because it is not in the options. the phone is jailbroken with redsn0w.

  • Guest

    Hi usmanaziz, my iPhone is already jailbroken, how do I manage to only install the iPad baseband? When I run the redsn0w.exe file, the dialog box is asking me to provide an ISFW file, which file is this one?

    Thanks,

    CRACK!

  • Anonymous

    You need to have redsn0w v0.9.6b5 or above to see the ipad baseband option. The download link is available above.

  • Anonymous

    You just need to jailbreak through redsn0w v0.9.6b6 (download link available above) and select the “install ipad baseband” option. You need to download the IPSW file of iOS 4.2.1 to the setup. You that download that from here:

  • Anonymous

    If you have baseband earlier than 05.14.02, you dont need to update baseband unlock to update. The problems with iPhone 3GS new bootrom doesn’t apply to iPhone 3G users. Do ask in the comment section if you encounter problems.

  • Captdb2000

    Hi, thank you for your help. It worked.
    So now all I have to do to unlock it is to run ultrasnow?

    Are you selecting “install iPad baseband” from redsn0w? You need to select that in order to unlock the device. If that doesn’t work, please try some other PC or a Mac.

    You have a new bootrom iPhone 3GS or later device which is still untethered jailbroken. You will need to jailbreak again on each restart for now.

    hi, I have iphone 3gs newboot rom. 4.2.1 & 5.14.05. I did everything carefully as stated in the instructions. Now my the firmware is updated to 6.15.00.

    Hi, I figured it out myself. But now to the other new problem!!! ITS STUCK AT THE BOOT SCREEN!!! I’ve read about your post of tinyumberla… but its not working. I cant click the button of exit or enter recovery…

    Thanks

  • John

    HELP PLZ!!!
    i tried 2 restore it via itunes v10.1 (the latest v available), but itunes cant restore it. &the error is “Error 1015″. I searched and read about this error but dont know how to resolve this. please help me out…
    Regards,

  • Carlos bueno

    The problem with GPS is not solved, but the lack of 3g band is solved just upgrading to IOS 4.2.1.

  • Anonymous

    Yes this error would come when you’re restoring iPhone 3GS. You need to download a program called “Tiny Umbrella”. After the error 1015 comes, close iTunes, run TinyUmrbrella and click on “Kick Out of Recovery Mode”. Your iPhone will be restored.

  • Anonymous

    Error 1015 should be recovered by Tiny Umbrella. Please search more on the procedure.

  • Anonymous

    Yes you might need to wait a few days before a solution of GPS is published. I will provide the link of the solution on this page.

    Please dont spread false rumors. The baseband 05.15.04 can be updated to 06.15.00 to be unlocked. Many people in this thread have already successfully tried that.

  • Sajid

    do i need to upgrade to ios 4.2.1 to unlock my iphone 3gs ?new bootrom, running ios 4.1, baseband ver 5.14.02)? i dont want to upgrade ios 4.2.1 as the unlock is tethered and comes with a lot of problems nd will be happy with an unlocked ios 4.1 phone. or is it impossible to stay on 4.1 at the moment? please help…thx

  • Anonymous

    Try jailbreaking your iPhone with the newest version of redsn0w (or the one given above) and select “install ipad baseband”. This will update your baseband while you stay on the current iOS. This will enable unlock with a tethered jailbreak.

  • Shom

    hi usman,
    I got everything ok, But everytime my phone turns power off or goes dead (no battery) it will not get on again, unless I launch RedSn0w, plug the iPhone in and select “just boot tethered” to kick boot my iPhone 3gs.
    This is very annoying as it means I have to carry a computer with me.
    what is way to resolve this problem
    I am not sure if there is a fix for this.thanks

    The final version for the untethered release is yet to be announced. We will update this post once the new procedure is available

  • Anonymous

    You will lose the GPS feature for now, everything else should work fine. The warnings are listed in the article above. The unlock for 05.14.02 might never be released.

  • Harris

    It is firewall on, turn firewall off should work

  • Mirumoto_kanawa

    Amazing!!! I was waiting for this solution long time. I thought I had to through my iphone away. Just one question… In the future it would be possible to update this software? Or we are locked forever with the 06.15 Baseband?

  • Anonymous

    Yes you’ll be able to update to a new baseband that is of higher numbering than this one.

  • Mirumoto_kanawa

    Since I update this version, I have 2 problems that I don’t know if they are normal:

    1. My mobile spends the battery too fast (every morning when I wake up the mobile is off out of battery without make any phone call).

    2. I can phone without any problem but many people who phone me think that my mobile is off. I tried to phone myself with another mobile and I had the same problem… the message from the telephone operator says that my iphone is off.

    Any solutions?

    The solution of your first problem is already posted, see this:

    http://www.hardwareinsight.com/how-to-activate-iphone-4-3gs-3g-without-official-sim-using-sam/

    The second problem has nothing to do with unlock, its rather an antenna or signal problem in your area. If you have an iPhone 4, use a protective band to avoid signal loss problem.

    You just need to jailbreak using redsn0w and then unlock your device by install ‘ultrasn0w’. The whole procedure is explained above. :)

    Ok I will point out something really usefull for u folks running windows and having 5.15.4 baseband with os 4.2.1… **IN ORDER TO GET ULTRASNOW(FROM CYDIA) WORKING **(remember you have to add the repo666.ultrasn0w.com to the sources in order to download it from your phone)
    1ST : go and download redsnow (latest version) on the dev-team Blog (http://blog.iphone-dev.org/)
    2ND : you Must absolutely upgrade your baseband to 6.15 in order to get ultrasn0w working.
    so PPL having problems with the stuck bootloading page in redsn0w… close everything and start it back (right click on the redsnow program). Choose “troubleshooting option”, follow the steps and select the XP SP2 mode. RE-Run every steps, and the bootload should run like a charm..
    3RD : you can now download the ultrasn0w from your phone and do the SIM unlock

    thanks a lot to the dev team and greenpois0n !!!

    ive jail broke my iphone with redsn0w and downloaded the ultrasn0w app but it still doesnt want to unlock to other networks can anybody help

  • laura_B

    hi and thank you so much for taking the time to offer this solution to us.

    i am on an iphone 3gs version 4.2.1 and modem firmware 05.15.04.

    i jailbroke the phone successfully using greenpoison. i then tried to unlock using ultrasn0w and although it seemed to work, i cannot load a network list and cannot find carriers. as background, i am in australia and my phone is an australian-made iphone but it was locked to north america’s att network. this is because my phone broke on the plane ont eh way from america to australia and the apple store in australia gave me a replacement one.

    the phone is also made in the 43rd week so i am not sure if it falls into the NEW or OLD category.

    so anyway — to try and get networks/carriers, now i am trying to update to ipad baseband 06.15.00 using redsnow but i am having a problem. i go thru the steps and when it comes time to choose the IPSW, i tried to find one on my computer but could not. so i downloaded iPhone2,1_4.2.1_8C148a_Restore.ipsw and i pointed redsnow to the download. i then continued through the redsnow process but on the last screen, i got, “an unexpected error occurred. please try again. try rebooting your device and changing usb ports.” i tried this but nothing. same error.

    am i pointing to the wrong IPSW when browsing for one and if so, where would i find mine? I double-clicked that downloaded IPSW and itunes opened but it asked me if i wanted to do a restore of my phoen and install the latest version and from everything i have read, i don’t want to go higher than my current 4.2.1.

    please help – thanks!

    thank you for your help and you’ve been terrific to us all!

    no u didnt have any problems with this method it works 100% u just want to have folks go to your stupid website to pay money for the unlock even though u not going to really unlock it

    yes, you can only update to a firmware version HIGHER than the one you’re currently running. Ultrasn0w only seems to work for a few specific firmware/baseband types (e.g. iPad baseband, but read the warnings first)
