Sorry for the late reply. I finally got around to taking a few pictures of the board.
I'm still having the same issue, and the Omega is running on the latest firmware.
I did notice one pin on the header was left unsoldered, there doesn't seem to be a trace going there though. I tried to add some solder there, but there isn't a pad for it to adhere to. Still the same errors after attempting, and after a fresh factory reset too.
