Why am i getting error 4000 when trying to update to iOS 14?

Currently on iOS13.6 (iPhone 8). Every time i try to update to iOS 14 (from iTunes or directly from phone), I get an error 4000 and the update fails.


Suggestions to fix please!


Thanks!

I have read elsewhere that deactivating your pass code and lock screen will allow the upgrade to occur (no error rec'd). Problem is that this is a corporate issued phone so i don't have ability to deactivate the pass code and lock screen.


APPLE - help please! From the number of posts i see on this topic, this is clearly a problem on your end!
