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 iPhone
Restart the iPhone
Restart iTunes
Reconnect the iPhone to your computer and restart the update procedure.

When finished, re-enable your passcode on your iPhone.

Update your iPhone wirelessly (via wifi).
