Two alternatives:
Keeping in mind that this workaround can affect keychain and/or Apple Pay (if in use, you might need to re-input data), try these steps to solve error 4000 on your iTunes:
- Disconnect your device from the computer
- Temporarily disable the passcode on your iPad
- Restart the iPad
- Restart iTunes
- Reconnect the iPad to your computer and restart the update procedure.
When finished, re-enable your passcode on your iPad.
or
Update your iPad wirelessly (via wifi).
