The problem is I have the new fimware and cannot upgrade. Therefore, i tried to ssh. That wouldn’t happen. Server denied. Then i tried to get into the configure file where they had everything commented. I attempted to edit it but still to no avail. Looks like i still have a lot to learn in linux. Btw, i will need another hashboard. I burn through these things like hot cakes.

No the change jumper and use SD card will let you downgrade:
