Error 4000 is not on the error list and is a bug in some versions of itunes for Windows

If it still happend after updating iTunes to the latest version

Either

(1) Use Wifi instead, Settings, General, Software updates

or

(2) Use itunes but temporarily disable passcode on the phone. That will clean out any cards you have in Wallet 

or

(3) borrow a Mac
