Sorry, I comment on another ticket

Size of the sd card is? Tried another sd card? Followed the instructions in ReadMe?

4Gb. Tried several SD cards and yes I followed the instructions in ReadMe. Seems like this is an issue covered in thread #24 however that thread seems to be for the non E3 board.

EDIT: Just to be sure, I cracked open a fresh 32gb SD card. Using this particular card, I was able to perform a normal update. It would appear these things are super finicky about cards. The other cards that failed actually work for file storage still and as checked on GPARTED they contain no oddities to the partition table. One of them was used to load firmware on this before. A total head scratcher here but thanks for your hints.
