TS3694 My Iphone 4 will not restore

I have the iphone 4 and it keeps crashing. The phone will not cut on unless it is hooked up to the charger. Once it is hooked up to the charger it will cut on but it doesnt go pass the apple logo. I put my phone in recovery mode and plugged it into my computer. I pressed restore on itunes to restore my phone but it always read "error 21." If any have experienced this and know how to fix the problem please let me know. Thanks

Error 21 typically accurs when security software interferes with the restore. In rare cases it could be a hardware issue

  • HT4061 My iPhone 4 will not restore.

    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?

    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:
    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.
    Restore and wait for the error.
    When prompted, click OK.
    Close and reopen iTunes while the device remains connected.
    The device should now be recognized in Recovery Mode again.
    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.

    Restore it as a new device first, then try again. If it still won't work, you're hosed, unless you can get hold of the old device and try backing it up again.

  • MY IPHONE 3gs will not restore?

    My Iphone 3gs suddenly turned itself off and then came back on saying 'Authorization required'.  After constant turning on and off it came back exactly the same each time, 'Authorization Required'.  When I tried to restore on Itunes it went into recovery mode and now it will not restore at all? It comes up with a message saying 'Unknown Error -1'. can this be fixed? Am annoyed as this is my fourth Iphone 3gs in under a year!

    Here is what this error can be about:
    Error 1 or -1
    This may indicate a hardware issue with your device. Follow Troubleshooting security software issues, and restore your device on a different known-good computer. If the errors persist on another computer, the device may need service.

    This Error usually indicates a Hardware issue with the Device... However...
    Make sure you have the Latest Version of iTunes (v11.1.5) Installed on your computer
    iTunes free download from www.itunes.com/download
    If using windows...
    Temporarily disable your firewall and antivirus software and try again...

    Hey Jrivers87,
    Thanks for the question - to me, it sounds like the issue started when you tried to restore, and now the iPhone is unresponsive? If that's the case, I'd take a look at this article which goes over a resolution:

  • Iphone 2G will not restore.

    I have an orginal iphone that was having some problems after the 3.0 update. I thought to myself that I would just give a it a restore and to give it a "clean" install. Now (while in DFU mode) it will not restore. Goes through all the motions and seems to be ALMOST done when, boom. Nothing but an the iphone unknown error 1012.

    Don't know if this helps, but I had a similar issue. I just kept trying to restore over & over again. Finally, on the 6th try, the full restore worked. My battery was really low (wouldn't charge, a different issue) & that seemed to affect the restore.
