Pinebook Pro won't turn on

[wdt]

>cd emmc/boot
I don't know where the emmc will be mounted, replace "emmc" as appropriate
the last line from "mount" should be it, after you have mounted it, of course
Use whatever file manager you use to mount it (whichever partition of emmc)
The md5sum on the download link is for the whole gz, everything
These md5sums are for individual parts
>the emmc can not be mounted.
Not the whole block device, no, but the individual partitions should be able to be (mounted)
--edit-- this from PBP, booted manjaro, looking at emmc, mrfixit, updated (emmc at /run/media/d/BOOT, that partition labeled "BOOT")

I don't know why your md5 numbers don't match

NOTE there is no standard for block numbers, mrfixit differs from manjaro, look at lsblk, / will be SD card (when booted SD)
