I have 2 pinebook pros which we will call PBA (which contains EMMCA_A) and PBB (which contains EMMC_B).
-PBA has had the keyboard replace and PBB has gotten the screen replaced.
-PBB did not want to boot properly after getting a new screen.
-I troubleshot the problem by swapping EMMC_B into PBA for testing. EMMC_B fired up and booted. I tried EMMC_A in PBB and got a proper boot after pressing the reset button.
-I swapped both EMMC back to original position. PBB needed to have the reset button pressed but booted EMMC_B just fine after that.
~2 weeks later
-PBB needs a reinstall of the OS on EMMC_B
-used USB/EMMC adapter to reflash the OS and now EMMC_B is no longer bootable on PBB, but works fine in PBA
-EMMC_A boots from PBB if the reset button is pressed. EMMC_B will NOT boot in PBB no matter how many times I press the reset button, but works fine in PBA
- I decided on a permanent EMMC swap to save myself some work. EMMC_A flashed with new image and placed into PBB will no longer work. Even after pressing the reset button. Now I cannot boot either EMMC from PBB (which is presumably still in good working order.)
I have a couple more troubleshooting tricks up my sleeve, but I am running out of ideas on this one and would like to know what the community thinks. PBA has the nvme adapter so I can use the manjaro-arm-flasher to flash the EMMC and see if that helps. Perhaps setting up the OS completely on PBA and then swapping to PBB might do the trick? Could the set up be causing the trouble? I also havent tried booting from SD or distros other than Manjaro, but I will try that stuff as I move through this issue.
