When I told you the phone wouldn't turn on, I think it was actually going through a reboot loop, but without displaying anything on the screen. After leaving it for about an hour and then picking it up again, it was emitting a soft warmth. I pressed the Power + Volume Down button, and it rebooted. I entered the code, and now it keeps rebooting, showing the Graphene OS logo first, then the wallpaper, over and over again
