Restoring from iTunes, get "iPhone disconnected" error every time
I'm trying to restore a backup from iTunes onto an iPhone XR running iOS 14.2. Every time I try, it gets all the way to "2 minutes remaining", then says the restore could not complete because the iPhone disconnected.
What I've tried so far:
- rebooting
- blanking the phone
- reinstalling iTunes
- trying both the standalone and Microsoft Store versions of iTunes
- running Decipher Backup Repair
- checking internet connectivity
- changing the USB cable
If it were actually a USB problem, it shouldn't only -- and always -- disconnect at exactly the "2 minutes remaining" mark.
What else can I try?
