This is a bug in iTunes for Windows. Try one of these suggestions. Turning off the passcode should work, but you will have to add your cards back to Apple Wallet if you are using it.


  • Temporarily disable your phone’s passcode before updating
  • Downgrade iTunes to version 12.8 on your PC
  • Update over the air by going to Settings/General/Software Update
