回答先: Completely dead device. Will not charge.Hi, I had the same issue and went to she Apple store. They initially told me it needed an update via iTunes but that was not the case. After connecting it with iTunes, it remained dead. If you press the home button together with on/off button, keep it pressed and then when it reboots, keep the home button pressed for another 15 sec you should force the ipad to a factory default. After this, I connected the ipad to a macbook and was able to do a new install. Maybe this helps?
