    It's hard to guess when I've never had the problem. I'm kinda like you if I got it in front of me I'd get it done one way or another. Give up? No but I'd like to know so I learn something new and know if I ever run across a similar issue sometime.

    Downgrade to 3.1.2

    Use blackra1n to jailbreak (no DFU required and fully pwns the device).

    From device fully powered up shift restore to a custom 3.1.3 (this only works from powered up because jailbroken with blackra1n, normally you would need pwned DFU).

    Put ultrasnow and mobile substrate .deb's into cydia's autoinstall folder.

    Open cydia, reboot, unlocked

    Disconnected the battery.

    What strikes me as the most impressive is you got the device down from 4.x to 3.x without DFU.

    Normally, the 4.x Recovery IMG3 will not play nice with the 3.x-formatted iBEC, and so you'd need DFU to upload a new iBSS to bootstrap iBEC... especially since iBoot changed in structure and version number from 3.1.2 to later. WFD either way... +1

    That's the thing. It may not have been on 4.X. It was in recovery loop when I got it so could very well have been on 3.1.3 already.


    Btw what is WFD?

    Okay, if it was on 3.1.3 then that makes sense--but why would the phone be on 06.15.00 if it was 3.1.3? That BB is unlockable as-is... if you have the computer you restored on, you could check the restore logs, that should tell you the build version, but... -shrug-

    WFD = Well Fing Done. I may or may not have made it up on the spot.

    EDIT: I think the "recovery loop for mismatched baseband version" was only instituted in iOS 4.2.1... maybe you just ridiculously lucky, or maybe DFU isn't as needed for that process as was originally thought.

    It could have neen updated to 4.1 and given the ipad baseband when the power button was still working. And then downgraded back to 3.1.3 for performance reasons. Not too sure, person just brought it to me as it was in recovery, no power button. I found out it had the ipad baseband and no wifi after I restored it to 3.1.3 first. Then I did my thing on it after I figured out what I was working with.

    That being said I am pretty sure I have downgraded a iPhone 3G from 4.X to 3.X before from recovery. Almost positive I have but little hard to remember, I get thrown curveballs like this all the time by people. Kinda fun figuring out a working solution

    Thats actually a misconception with 4.2.1. Recovery loop on 4.2.1 isn't actually caused by a mismatched baseband as Semaphore had originally though.

    P0sixninja has referenced both a formatting error in the NAND partitioning scheme that won't get applied in the ramdisk, /and/ a check in the BBUpdaterExtreme binary (that only exists in the Restore Ramdisk, not the Update one) IIRC.

    This behavior persisting in iOS 4.3.x (with a new iBoot) and /not/ occurring in either "Update" behavior restores or custom <UpdateBaseband = false/> ramdisks is (IMO) evidence enough that it's a binary check.
