I have a second hand iPad 2 that will not restore.
It is stuck in recovery.
I have tried using redsn0w and TinyUmbrella to get it out of recovery mode but as soon as it reboots it goes right back into recovery mode.
If I try to restore with itunes I get error 9
I have tried 3 different computers and 2 different cables.
If I try to manually make it go into DFU the closest I have gotten is instead of a recovery mode screen I get a low battery screen with the lightning bolt and plug and the red minimal battery. At that point, if I connect it to a wall charger after a few minutes of charging it goes right back into the recovery mode screen.
