my brand new Oculus Quest is stuck in USB update mode, Auto scrolling without me touching any buttons, and powering itself on and off again. I have tried holding down the power button for 2-30 seconds with and without the volume buttons. When plugged in it has a solid red light on as it is powering itself on and off again. I had it working last night and this morning with various apps and waited until it went through the full update when I first set it up. I am really hoping for an easy fix and that I haven't bought a dud. Any ideas?
