April 2017 - LG G5 android update stuck at secure start up - knock code not registering which is a big concern since this is supposed to be a screen software update. It's still showing 30/30 attempts and there is a soft ticking sound periodically. The screen does register the "knock" by flashing the correct square and the pattern worked yesterday so clearly the update is screwing the phone.
Can/Should I shut it off? If so, how?
