i keep receiving an unknown error (-1) when i am trying to update.  My iPad is not even a year old and it saying that it may be a hardware issue?  what gives?
Error -1
Attempt to restore your iOS device two more times. If the issue is still unresolved, the device may need service.
The "device may need service" means a hardware problem. In that case make an appointment at the Genius Bar of an Apple store.
