Hi, After updating the iPad Air 2 using OTA to iOS 9.3.3 from iOS 9.3.2, the device was bricked. It is now not able to restore itself to neither iOS 9.3.x or iOS 10 using iTunes on any computer I tried. iOS 10 shows error 14, and iOS 9.3.x shows error 56. Has anyone encountered such problem? It looks like I'll need to contact Apple at the end.
