"Update fails on brand new iPad: Received brand new iPad (8th Gen) today on version 14.4.2. During set up, said 14.5.1 available. Tried to update twice, but get error 4000 (unknown error) after backup complete and software extracted. What to do?"

What to Try:
1. Cleaning the Space:
A. Clean TV and Music Libraries:
Remove all unneeded files from your TV and Music Libraries. Full-Movies take up 2-4GB typically, and a bunch of those would take up a load of storage, ideally. So, if you have any movies that are not needed, then delete them.
B. Clear Temporary Internet Files:
Clear your Temporary Internet Files (Cookies & Cache) of Safari:
