Thread: Downgrade 4.0 to 3.1.2

    Default Downgrade 4.0 to 3.1.2
    I just got the 3gs 4.0 (new bootrom) from AT&T. It has never been jailbroken.

    I have been trying to downgrade to 3.1.2 but keep getting the "1394" error message. I have followed all the instructions from the forums.

    Can it be down graded?

    As far as I know, no, you can't downgrade it because Apple won't let you use an old firmware to update. Normally the workaround is you use an old SHSH backup to trick itunes but if the phone is new then you don't have any SHSH backups.

    Correct.
    Have they released the jailbreak in the app store yet?
