    Xbuntu / iProduct help (Downgrade to 3.1.2 on iPhone 3Gs 4.3.3)

    Since my time is limited I'm just copy/paste here what I have posted in YA,

    I'm looking to downgrade my iPhone 3GS (currently has OS 4.3.3) to OS 3.1.2 or OS 3.1.3, I already have the OS 3.1.2 ipsw. However, after 7 hours of searching for a way, I cannot find a (working) way to revert back using Linux, as it can have neither iTunes nor any of the jailbreaking software that can allegedly accomplish this, and it's a bit tiresome.

    Also, feel free to ask for additional details if what I have provided is insufficient

    Thank you in advance to anyone who can help!


    I'm very new to Linux, as my "charming' older brother would say in not so nice terms, however it runs so nice on my less-than-new compy I'm trying my best to get used to it, however I need to downgrade the OS on a iPhone and everywhere I've looked so far in my search has been fruitless! I need to do this asap, so any speedy help I would be very much grateful for!

    Also, if there's anything I likely won't know (such as terminal commands) to go along please touch on that a bit too? I've been searching up things for days but Linux is alot more confusing than Windows or OSX.

    Hello and Welcome!

    It's been a while since I dealt with an iPhone in any way, but AFAIK the only way to downgrade iOS on a phone is via iTunes.
    I believe you would have to perform a Restore iPhone, and then point the restore to a saved Backup of your phones settings and info.

    Incidentally, I used to work on Apples support line . And the tech line won't support downgrading.

    Things may have changed since then, but I doubt it. And without sounding like a brushoff, you may have better answers for this on an Apple based forum.
