So my son's Ipod battery is dead. I have called Apple and it's covered but I need to ship it to them, (no store close by). The only time the Ipod turns on is when its plugged into the wall. It will not turn on while plugged into the computer. I want to restore it so it removes the jailbreak but can't because it won't work connected to the PC. It is already at 5.1 so I can't do an over the cloud update since it's already updated. Any idea how to resolve? Is there a combined push of buttons that resets the ipod back to factory? I could do this while its plugged into the wall.
