I have also shot myself in the foot with an attempt to write the Manjaro PinebookPro Preview 4 image to emmc.
To be honest I could have been easily avoided, I did not get it to install, but on the other side I should just have stopped there as SD boot was still fine. However, adventoritis got the better of me and after my failed attempt to istall to the emmc the emmc did not boot anymore, with actually a green light and the SD card did not boot at all with an angry green and red flashing power ID.
Removing the bottom cover of the PinebookPro and switching the emmc off (see wiki) helped and now i can boot at least from SD card again.
As far as I know I can reactivate the emmc booting from SD card and then turning the switch back on in the decisive moment between uboot load and kernel start. there is a 2 sec. pause there. If the timing is right the SD card is supposed to continue to boot and the kernel can find the emmc and it can be flashed with something working.
After my previous, slightly discouraging experience I will postpone that exercise until I know what I actually want to have on the emmc and also how to get it there safely.
For now the SD card works rather fine.
I am mostly writing all this to give people with a similar fate a bit of courage and avoid the heart attack I almost felt when I blundered it up myself...
Don't Panic
