broken emmc

[nieral]

Hey!

My Pinephone BH won't boot anymore. I have PM Os installed on the emmc, the sd card as an additional drive. It worked very well with the stable branch. Three days later it was dead. When pressing the power button it stucks with the 'led test' and makes a short 'click' (which seems to be specific to pm os) and restarts over and over again. that it quits at the "led test" reminds on the error bieps from bios, when something essential did go wrong. So: no boot screen, nothing.

What I already tried:
- completely charge the battery
- flash the sd card with jumpdrive:
The phone booted into the jumpdrive modus, but: lsblk did not show the emmc nor the sd card (which is strange). I can unplug the usb cable while it runs jumpdrive, so the battery works well.

I think the emmc is dead. Can I replace it??

I appreciate any idea.

There is a factory test image very close to the bottom of the demo builds in the postmarket sub-heading on the pinephone os wiki. Use it to test your hardware. That's all it does.

The Tests with the factory test image showed no errors and I could even flash the factory test image to the emmc and the phone booted from the emmc :-) Jumpdrive now shows the emmc and the sdcard. I don't know what was the reason for this error, but a failed upgrade seems to be a good guess. Thank you for the support.
