Hello! I have an iPad 2 that worked perfectly until one day it entered recovery mode. Nothing happened before, just reading a book and it hung. From there I can't recover the iPad. It shows the recovery iTunes logo, reboots and sits there with the Apple logo. Forever. I tried using Windows and Linux, iTunes and idevicerestore, 3 different cables, 3 computers, even a Mac. Nothing. Basically I think the iPad must enter "restore mode" after first reboot when recovering, where the Apple logo shows a progress bar below. There's the problem, it is NOT entering restore mode (different from recovery mode). Any help?
