Left my Air running the 9.3 to 9.3.1 update last night while plugged in to a charger. Upon return this morning - nothing, dead, and i means completely dead, no screen, no low battery, no graphic to plug into iTunes nothing. none of the reset combinations worked. I've connected it to iTunes and I'm getting iPad in recovery mode as a status. Downloaded the iOS full image, run the upgrade and now I'm getting an apple logo on screen, but error 4005 in iTunes that the iPad could not be restored. Anyone else had this issue?
