i had that a couple times too. wrong key combination trying to get to recovery mode to wipe cache. freakin had to hold down power off until my finger was about to fall off before it shutdown.
i still cant remember correct sequence, so i have been shy to try...again!
@Golfdriver97...if the op saw the same as me, there are no options...only in small letters at top lh says "fastboot..." cant do anything cause no cursor or any options available to select...dead to any and all inputs from any button or on screen!
cant really remember the incorrect way that got us into the op situation, but dont really want to try and confirm it either. if the steps are correct in my last, can someone confirm?
