Hey. Bought a new, sealed iphone 8. Tried to update the software to ios14, but error 4000 appears and stops the process. I tried to update it on phone and manually connected to computer, updated the itunes as well. None worked. Could someone help me please?
iPhone 8, iOS 11
Keeping in mind that using the workaround provided in this similar thread you'll need to re-enter things in your Keychain or Apple Pay (if in use), see this similar conversation and follow the instructions in the reply marked as "Apple Recommended":--> My iPhone 8 fails to update to iOS 14 - Apple Community

But please, do not insult real geniuses, LOL!.
I don't belong to that category, I'm just a user like you, now very happy that you worked it out.
Take care.
