    Is it stuck in DFU or restore? Do you see the connect to itunes symbol? Just hold home and sleep at the same time till you see the Apple logo. That gets it out of DFU for me if I mess up the steps on redsn0w

    Once redsnow started it, I updated cydia, unlocked and restarted it again via redsnow(just boot tethered now) it was working fine but as i kept it on my desk it gone into sleep mode and when i tried to wakeup it from sleep, i found it is in DFU mode again............
    my SHSH are only saved 4.2.1 and +.
    I started tinyumbrella and started TSS Server and also iREB at the same time and restored my iDevice with custom 4.1 with out any error( Error 3194 and 1600 and 1601 passed). iTune on PC was showing all restoring process but iPhone Display was black blank.......then after finalizing iTune told me that my set is going to be restarted after comleting restore,...
    after all iPhone screen was black and blank all the time, iTune again told me that my set is started also set given me sound of connecting it to pc(Sound from set, not the sound from PC) and iTune asked from me to restore it from back or new phone, I told it New Phone and it started syncyng and completed...
    Then it was showing all things in iTunem capacity, Serial No, iOS Version etc.... but sets display was black and blank.............................
    please help me to restore it before 10th February............

    solving error 3194

    Fix Error 3194
    The fix is the same regardless of what operating system you are using:

    Quit iTunes
    1- Locate your hosts file, in Mac OS X this is /etc/hosts and in Windows this is c:\windows\system32\drivers\etc\hosts
    2- Open the hosts file with Administrator privileges
    3- Add the following lines to the very bottom of the hosts file:
    74.208.105.171 gs.apple.com
    4- Connect your iPhone to the computer
    5- Launch iTunes
    60 Put the iPhone/iPad/iPod into DFU mode by turning the phone off and then holding down the sleep and power button for 10 seconds, then release the power button but hold onto the home button until iTunes tells you that the device is now in recover mode Use the iTunes Restore feature as usual with the iOS device

    6- start restoring

    Dear Mahmood I have upgraded it with 4.1 custom but it is in dfu mode and have black and blank screen at all.
    No other display there.
    I don't need iOS 4.2.1 if my set start working.
    And will iPad BB work on iPhone 4?
