Side Notes:
Going from Android Q to 8.1 I got a Black Screen after the Non moving google logo screen on boot. Afterwards, the phone seemed completely dead and would not turn on. I held Volume Down+Power for almost a minute and it finally booted into Fastboot. I went through the steps again and this time I noticed the Non moving google logo screen had a lock at the bottom. I tapped it a few times and it then told me my install had an issue and I needed to do a factory reset. I chose to do so and it completed and rebooted with no issues.
