Transfer 7 to 11 pro
transfer is stuck on system update???? I've tried 3 times and after a very long time being stuck it then goes to transfer failed -2
iPhone 7, iOS 14
Set up the phone without the phone to phone transfer so that the update happens cleanly.
Then use a computer to restore it or DFU it.
Then choose the transfer method of choice.
