I had moto g7 power a few weeks and cracked the screen. I watched a few video and replaced screen myself. It worked fine for about an hour, at which point it died and has not responded to anything since. I know how to reset it, blankflash, etc, it doesn't show in device manager under the Qualcomm port. I have used that method and it doesn't work. I replaced the battery, frame, screen -again, LCD cable, nothing causes any reaction. I'm waiting on a charger cord, never heard of charger dying. I wont pay another dime and will consider the $200 lost. Any ideas?
