I have a Pinephone Beta Edition that shipped on May 26, 2021. It was working fine until a couple weeks ago when it began doing this.
I had the Manjaro/Plasma Mobile that it shipped with, plus I had Mobian/Phosh booting from an SD card. I didn't even use it all that much, because Bluetooth headset is kind of important for me day to day, which does not work for phone calls.
I was updating the Manjaro install when it quit. I think it was rebooting after updating, but I'm not certain. Now I cannot turn it on with the battery installed and USB disconnected.
With or without the battery, if I plug in the USB cable, the LED turns on green. After about 5 seconds, the display backlight turns on, screen is blank. At 7 seconds the device appears to shut off. If I press the power button to turn it back on with the USB cable still connected it repeats the same process.
I tried the SD card that was working fine, no difference.
This seems to me to be either:
1. A hardware failure. In which case the best option is probably to replace the board.
2. A BIOS, boot loader problem (I'm not very knowledgeable about this). I'm not sure if an update could have possibly affected this, but the coincidence with the update is suspicious. Nor do I know if this firmware is strictly read-only, or if there is anyway to fix it.
