I'm trying to restore a backup onto my iPad 2, and every time I try to restore it, it does what it should where it starts to load and has the estimated time, etc. But when it finishes it says that there was an unknown error. When I tried to restore it, it did the same thing but instead gave me the error 1604, which I still can't get fixed either, but I tried restoring it on a different computer and it worked fine. So I thought there was something wrong with the computer that I originally tried it with that was causing the problem, so I transferred the backup onto the other computer and tried it and it game me the exact same error. I've spent days trying to fix this, and nothing has worked. I already looked at and tried doing what the support sites say with troubleshooting, restoring, recovery/DFU mode, etc. but nothing has worked. My iPad is on iOS 6.1 and I just upgraded iTunes to the latest version before I started all of this, and it is jailbroken with Evasi0n, although I've tried it with and without the jailbreak installed and it still has the same outcome. Is it a memory problem? Has anyone had the same problem and fixed it, or has any suggestions? And if not, is there a way that I can easily extract all of the files from the backup and put them on my iPad without using iTunes? Thanks.

iPad 2 Wi-Fi, iOS 6.1

    All it says is "iTunes could not restore the iPad "iPad" because an error occured" without giving an error code.

    From here: http://support.apple.com/kb/TS3694

    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.

    I've already looked at that page. I got that error when trying to restore everything, and I've already restored it with the other comupter, so I'm not getting the 1604 error anymore, because now it isn't giving me an error code.
