    Default PLEASE READ: For those stuck in reboot loop or recovery mode. Wrong use of Spirit

    For those who did not read carefully before using Spirit jailbreak and now you are stuck in a recovery mode or reboot loop. Please read this article from MuscleNerd of the Dev Team:
    Preventing baseband update as a last-ditch effort [iPhone Dev Team]

    Preventing baseband update as a last-ditch effort


    What is it?

    This page describes a “last-ditch” way to prevent a baseband update for those who ignored the warnings on http://spiritjb.com to not use Spirit if you're using blacksn0w on an iPhone 3GS without 3.1.2 SHSH blobs on file.
    This is not a jailbreak or an unlock by itself. It's much safer than the “pull your USB cable during Firmware Update” method that's making its way around the forums (that method has the potential to brick your baseband if your timing is off).
    Some people who were using blacksn0w on their iPhone 3GS at 3.1.2 tried to apply the Spirit JB despite all the warnings against this. Those who did usually found themselves in a reboot loop or stuck at the Apple or recovery screen. If they did this on an iPhone 3GS without 3.1.2 SHSH blobs on file, they got stuck with an inoperable phone. That's because restoring to stock 3.1.3 (to get out of the loop) also updates the baseband past the point where the currently released unlocks will work.
    The number of iPhone 3GS jailbreakers using blacksn0w who do not have 3.1.2 SHSH hashes on file with Cydia is probably very small. Do not use this method if Cydia has your 3.1.2 SHSH hashes on file – it's overkill! Just restore to 3.1.2 using your saved hashes instead. (But if you've already got 3.1.3's baseband on your iPhone, it's already too late for you and you must wait for the next unlock. This method doesn't change that.).

    When should I use this method

    Only use this method if you meet *all* of these requirements:

    • Using an iPhone 3GS; and
    • No 3.1.2 SHSH blobs on file with Cydia (or locally on your computer); and
    • You've never updated or restored (or bought your iPhone with) stock 3.1.3 before; and
    • Have access to a SIM card that will allow your iPhone 3GS to activate through iTunes. This is an important requirement because if you don't meet it then this method is pointless since you won't be able to use the Spirit JB. Note that you'll only need this SIM card to activate the iPhone before running Spirit, and you don't need to keep it after that.
    • You're currently in a reboot loop or stuck in recovery mode. If you're not, and if the only thing you're trying to do is switch to an untethered jailbreak, then please reconsider what you're about to do. (You may want to leave well enough alone for now.)
    • Please consider this method a “last-ditch” way to undo your previous mistake only.


    What is the method

    This method “mostly” restores to 3.1.3, but makes the restore process error out at a safe point by removing the LLB image from the stock IPSW. The error will occur before the NOR is erased and before the baseband is reflashed.

    1. Make sure you have rslite or iRecovery handy and that you can run it. You'll need to use it after iTunes errors out.
    2. Unzip the 3.1.3 IPSW. You'll be making three changes to it.
    3. Remove Firmware/all_flash/all_flash.n88ap.production/LLB.n88ap.RELEASE.img3
    4. Edit Firmware/all_flash/all_flash.n88ap.production/manifest. Remove the first line (LLB.n88ap.RELEASE.img3) then save back the file.
    5. Remove the two references to LLB in BuildManifest.plist. You want to remove the lines starting with <key>LLB</key> up to and including the next </dict> (this will be 17 lines). Do this twice…once in the first half of the file, and once in the second half.
    6. Zip it all back up. Keep in mind that the top-level of the zip should be that directory where BuildManifest.plist is. (Don't zip it from the folder one level up from this by mistake).
    7. Restore or update to this modified IPSW (not the stock one from Apple!). It will eventually error out (error #6).
    8. Use rslite or iRecovery to get past the subsequent recovery screen. Using rslite, you'd do:
    9. % rslite
      rslite v0.2 - by the iPhone Dev Team, 2009.
      --THIS IS AN UNSUPPORTED TOOL--

      Connecting...
      [Recovery] setenv auto-boot true
      [Recovery] saveenv
      [Recovery] reboot
    10. Using your valid (but temporary if need be) SIM, activate the iPhone then use Spirit from http://spiritjb.com to jailbreak. Then use Cydia to install the blacksn0w unlock.

    Guys,

    I'm complying with all the stated conditions for this method. The only thing hard for me now is to get a AT&T sim card to activate.

    Reading this (sorry for the ignorance) it seems that after the restore with the modified ipsw I would be in a position to just run blackra1n and jailbreak it, wouldn't I? If yes, I know that this would still leave me with a thethered JB but would save me from the recovery loop.

    Thanks.

    No you need to run spirit to jailbreak.

    On a 3GS without 3.1.2 SHSH this process protects the ability to unlock but it destroys your chances of using blackra1n, redsn0w or pwnagetool to jailbreak.

    This method still does not work on the MC model phones (one those have cable and itunes logo at startup). Simply because spirit needs the phone in ready condition for jailbreak.
    I did everything as given above but then again got stuck as the phone is in the cable itunes logo condition.
    Any suggestions ?

    MC means nothing special for iPhones. You can have a MC model 3GS that has new or old bootrom.

    For iPod touch, MC model means that some of the older jailbreak methods do not work (as this indicates an updated bootrom).

    We are already discussing this in another thread. http://www.hackint0sh.org/f247/128581-2.htm#post541647

    I'm also have all above mentioned conditions, but I do not have an original SIM card. The phone is locked to AT&T. Can I activate my 3GS using any AT&T SIM or should it be original one?

    On a 3G or 3GS, most AT&T SIM cards will activate the phone.
