    Unhappy iPhone 4S stuck on DFU mode after upgrade 5.0.1 -> 5.1.1 using redsn0w
    Hi,

    I used the latest redsn0w 0.9.15b3 to upgrade my iPhone 4S from 5.0.1 (9A406) to 5.1.1 (9B206) thru the 'Extras > Even More > Restore' feature. However, there was an error during the upgrade process and since then my device is stuck in DFU mode (as per TinyUmbrella) and soft DFU mode (as per redsn0w). I've tried the Home+Power button trick and that didn't help, neither did 'Recovery Fix' or 'Exit Recovery' from TU. Tried installing 5.1.1 using TU and iTunes (Shift+Resore) option and that returns either 1600 or 1601 error message. Tried different PC and iPhone cable combinations and always get the same result.

    Please help me. Now my iPhone is just a paper weight!

    Thanks,
    Arry
