Since there are 3GB replacement mainboards available now for the #pinephone I made a video on the process of replacing the board:

@martijnbraam Thanks for the hint, ordered the upgrade.

@ruff @martijnbraam

The old mainboard UBports edition says goodbye after comparing a backup image to emmc.

@ruff @martijnbraam

Thanks @martijnbraam for the video.

Exchanged the mainboard and my still works. Now running jumpdrive to put my image onto the new emmc.

Did anybody have a good idea how to "dispose of" the old mainboard? Wouldn't it make a nice sbc usable as an access point or something?

@chrichri @martijnbraam
Mine didn't go that well unfortunately, all boots and loads but touchscreen doesn't work on a new board.

@chrichri @martijnbraam and putting back original board makes it (touchscreen) working again. So it was a good experiment, almost flawless :)

@ruff
Sorry to read that the board didn't work. I had problems with connections at first also.

But after reconnecting everything the new board worked.

Maybe @pine64 is willing to replace it?

From your description it really looks like the board is the problem and that you didn't make any mistake replacing it.

@chrichri Yup I've opened a case with them, didn't get any response tho yet :) Either way I have a long xmas break and some tools to learn schematics and come up with the plan on how to debug and confirm whether it's me or the board.
