My iPhone 4 will not restore.  It displays a picture of a USB cable with an arrow indicating I need to connect to iTunes.  iTunes sends me codes 1603 or 1604.  I follow the instructions and get the same result. Is there anything else I should do?

iPhone 4, iOS 6.0.2

    Here's the meaning of error 1604 (also applies to 1603):


    Error 1604

    This error is often related to USB timing. Try changing USB ports, using a different dock connector to USB cable, and other available USB troubleshooting steps (troubleshooting USB connections. If you are using a dock, bypass it and connect directly to the white Apple USB dock connector cable. If the issue persists on a known-good computer, the device may need service.

    If the issue is not resolved by USB isolation troubleshooting, and another computer is not available, try these steps to resolve the issue:

    1. Connect the device to iTunes, confirm that the device is in Recovery Mode. If it's not in Recovery Mode, put it into Recovery Mode.
    2. Restore and wait for the error.
    3. When prompted, click OK.
    4. Close and reopen iTunes while the device remains connected.
    5. The device should now be recognized in Recovery Mode again.
    6. Try to restore again.

    If the steps above do not resolve the issue, try restoring using a known-good USB cable, computer, and network connection.



    The above comes from this article:

    Yeah, I did all of that already...at least twice.  Does that mean my phone is "cooked"???

    Is your iPhone jailbroken?  If so, it may be "cooked".  If not, it sounds like the evidence points to your computer's USB port or your USB cable.

    One more thought: If your iPhone is not jailbroken, you may well have to try to get it into recovery mode many times.
