Thread: Going back to 3.1.2

  1. #1
    Default Going back to 3.1.2
    Ok I have a iPhone 3GS which was running 3.1.2 using tethered jailbreak.

    My dock connector broke so I brought a new one and pulled my iPhone appart and replaced it, job done.

    When I connected it to iTunes it wanted to do a restore, but I stupidly let it download 3.1.3 firmware.

    I tried installing my jailbroken 3.1.2 firmware and it says it's not comparable with my iPhone, erm... It is iTunes as I used it before!

    So how do I go back to 3.1.2? as I have some apps that need a jailbroken firmware, seeing as 3.1.3 can't be jailbroken i'm kinda stuck

    you just replaced the dock connector, not the whole phone right / did you get your 3.1.2 SHSH blobs cached with Cydia? if you did (when apple was signing them still), you can use them to permit 3.1.2 restore, regardless of if apple is signing them or not.
    more info here:

    your baseband won't downgrade, but you could downgrade the OS to 3.1.2 and get your jailbreak back... but only if you had 3.1.2 keys cached with Cydia.

    it's explained in the links I posted in greater detail, I believe.

    essentially just use FWumbrella, pop in your ECID, choose Saurik for server, OS3.1.2, and try to retrieve... if it works, it's cached on his server (and you've downloaded a local copy on to your machine at the same time)

    if it times out, you're stuck in the same boat I am
