can't update to ios 8.4. keeps freezing on "verifying iphone" stage for hours...
I tried to update my iphone to ios 8.4, but the screen keeps showing apple logo and a bar (no movement on the bar) and itunes is saying verifying iphone but nothing hours for more than 3 hours now. took the cable out, restarted the computer, restarted the iphone... serial number also changes to n/a, despite there was a normal serial number when i first plugged it in. no changes. any suggestions?
iPhone 6, iOS 8.4
