I'm trying to sync my iPhone with iTunes.

I keep getting the error message - The iPhone cannot by synced. An unknown error occurred (-4).


Using:

iTunes 12.1.1

iPhone 5s iOS 8.2

Desktop PC, Windows 7


I have already tried:

uninstalling iTunes and reinstalling it

resetting iPhone


Anyone know how to resolve this issue?


Please help. Thank you!
