    Unhappy Stuck in DFU Mode - Need Help

    Iphone 3GS
    Baseband - 6.15.00

    Tools used
    RedsnOw 0.9.6rc16
    sn0wbreeze 2.2.1
    TinyUmbrella 5.00.06

    Steps Taken So Far
    Was stuck with error 3194 but recovered it by using Tiny Umbrella
    Restored the device to 4.2.1(orginal firmaware) threw me error 1600
    Started Tiny umbrella
    Used redsn0w to enter DFU mode
    Used sn0wbreeze to create custom 4.2.1 firmware
    Itunes to restore using custom firmware
    Successfully restored but my iphone got stuck in DFU/Recovery Mode
    Again used RedSn0w for tethered reboot
    Iphone rebooted with pineapple logo and again flashed and went back to DFU mode

    Action Taken to recover from DFU mode
    Used greenp0ison but still same problem
    Used tinyumbrella fix recovery but no use
    Used iREB to fix recovery loop but still no use

    I have seen many blogs that tiny umbrella helps to fix this issue which they say by clicking on exit recovery will solve the issue. But in my case the 'Enter Recovery" and "Exit Recovery" buttons are Disabled.

    Anyone please help me resolve this issue. I have been researching on this for two weeks but still unsuccessful.

    Do you have a saved SHSH for iOS 4.2.1 ?

    Are you sure it is DFU mode (black screen) and not recovery mode (connect to iTunes logo)?

    I'd run TinyUmbrella see if it can retrieve any SHSH for your device (just in case you did actually save a SHSH with Cydia - without realising it)

    As you appear to have not saved any SHSH you can NEVER restore to anything except iOS 4.3.4 (and maybe if you are very lucky 4.3.3 - as it sounds like you had a valid SHSH for 4.3.3 at some point).
