Using iTunes upon my Win 10 PC to update my iPhone XR to iOS 14 from its current iOS 13.7 build I receive an "error 4000" an unknown error occurred
Any ideas ?
I've tried this twice now, same issue.
iPhone XR
Same issue here with error 4000 - latest iTunes version, whether iTunes
from Apple or through the Windows Store - iPhone 11 Pro Max and iPad 6th
Gen. This has been happening for the past few update cycles. I believe
the problem lies in iTunes thinking the phone/iPad is locked, even if
you keep the screen on and enter your unlock code when asked. The only
way I have found to update using iTunes is to turn Passcode off in
settings, then it will update. Only thing is it will delete and
debit/credit cards in Wallet and you have to re-enter them. Apple really
needs to fix this.
What do you mean updating directly from iphone? There's no pending update and I can't delete and reload since iTunes doesn't exist anymore as an app and I don't want to be forced into Apple Music.
I didn’t have any problem with an OTA update - except I had to verify twice. When upgrading from 13 to 14, 14 doesn’t exist yet on any hardware so it can’t be 14 causing the original problem.
