Phone locked up

[Sixguns]

My wife was doing the latest software update and when it asked for her to unlock her passcode it has since locked up. My computer no longer sees it and the phone wont turn off and is stuck on the loading screen. Any ideas? Do I need to wait for it to die and see what happens after that?

Didn't work. Had to let it die. After that it came back up like normal.
