    Hi everybody! I have had my Iphone 32GB 3GS 3.1.2. Jailbroken through BlackRa1n for about 3 Months now... My battery was fully charged one day at school I went to hit the wake button and it refused to turn on... Including Holding the power/menu button to reset... I plug it into Itunes and it says device unrecgonized and Itunes says "device has malfunctioned and needs to be restored... But as its a 3GS It will freeze during Restore... I cannot put it into DFU Mode through the Iphone itself because its basically dead... What do I do!?!? please help me out! :confused:

    If the phone is currently jailbroken, has old bootrom and you can get into recovery mode use iTunes to restore to custom restore 3.1.2 IPSW

    or if you saved your 3.1.2 SHSH in Cydia, use Saurik's restore method.

    Use Pwnage Tool to make a custom Restore 3.1.2 IPSW (iClarified has a tutorial). Then you have to be able to get your phone into recovery mode, use iTunes, pointed at custom restore IPSW to fix it.

    Not if (as you stated) you are currently jailbroken. Make sure to use shift + restore (on pc) and select your custom ipsw.

    Old bootrom is untethered jailbreak - this method will work on that phone
    New bootrom is tethered jailbreak - this method will not work on that phone

    Simple as I can make it. Model # doesn't matter except for IPT

    There is no link. If you want to look thru the threads here, plenty have done this successfully.

    Currently jailbroken, old bootrom, can get into recovery mode

    Get or make a custom restore 3.1.2 IPSW (if that's the firmware version you want) and use iTunes to install it.

    If on a Mac, use Pwnage Tool to make the custom restore IPSW, use iTunes option + restore to point iTunes at the IPSW you made (browse to it)

    If on PC, find the correct custom restore IPSW (must start with 2.1.. for 3GS) and use shift + restore to browse to custom restore IPSW.

    That's it.
