I upgraded my iPad Pro 12" to iOS 10.3.2 yesterday via iTunes. The update looked as if it succeeded but when the iPad restarted it was stuck at the Apple Logo. I forced a reboot but it still wouldn't go past the Apple logo. I plugged it back into iTunes and was told there was a problem detected with it and got a suggestion to installed the update again - which I did but it got stuck at the same point. Where I'm really lost is I cannot restore the iPad! What happens is every time I restore from either iCloud or an iTunes backup the iPad starts fine but as it's downloading my apps from the iTunes store it appears to crash with a white spinner on a black screen. If I reboot the device at this point, it again, get's stuck at the Apple logo on boot. I have tried 2 different iTunes backups and 2 different iCloud backups - they all behave the exact same. If I set my iPad up as a new device it works fine. Have I just lost everything?
