Bricked Motorola X4, Dead Display
I went to replace my Google Fi / Motorola X4's screen/digitizer using a replacement I bought off of Amazon. The procedure went fine, but afterward neither the old, nor the new screen will light up! The process was pretty straightforward, too. No evident physical damage occurred. I moved over the home button / fingerprint scanner, and touching it still makes the little phone vibrator move, so it seems the phone is still alive, but the display is quite dead.
I imagine any of 3 things may have happened:
1) Static electricity damaged the mobo while I was replacing the digitizer.
2) I used a hot plate to loosen the screen's adhesive (per Youtube "instructional" video) that suggested to keep the phone on the heat at 80C for 10 minutes. I used an IR thermometer to verify that the temp was in range. Regardless, maybe heat damaged the phone.
3) Software has bricked the phone to prevent tampering.
If you have any experience with this phone, or have any conjectures about what happened, or you think you can help, then please respond. Thank you!
