hi, I have a pinebook with remixOS, I tried booting Ubuntu mate from sdcard, but can't see any display. Could you please help me in this regard. Thanks

i do not think that remix image you have was built for the pinebook. the pinebook will not run with pine64 images, so did you build the remix image for pinebook or are you trying to use a pine64 image?

Can anyone direct me to a resource for installing a new eMMC? Can't seem to find one...

Remove screws from base, careful as front 4 screws are smaller than rest. Remove base panel with trackpad towards you. On the right hand side at rear is the mainboard. Unstick the large sticky panel at the rear and gently pull it up and towards you. A metal panel should unlock from the mainboard still stuck to the sticky panel hinging on the sticky panel closest to you. You should now see the emmc chip which can be removed by lifting up. Click the new emmc in place. Click the metal plate back to the mainboard and smooth back the sticky panel. Fix base panel back on. Done.
