    Additional recommendations

    If the device update was successful, but it started in recovery mode, perform the above steps again. In step 4, now select “Restore” rather than “Update.” When recovery is complete, you will need to configure the device based on the backup.

    If the update continues to fail, do the following:

    1. Check for updates for your Mac or Windows computer. If the update required restarting the computer, check again for updates after the restart.
    2. Try restoring the device using a different USB cable.
    3. Try to restore the device using another computer.
