Proper way to use mrfixit update

Right, but unless you had either of those parameters wrong, it shouldn't fail.

If this is on the Pinebook, 64k might be faster that 4m.  At least that's what I found with the SD cards that I've used so far

Not in front of the machine but I think I used /dev/mmcblk2 for sd card. And I just clicked and dropped the file path in. I can try 64k.
