Firmware Revert

I've just gotten the most recent 3d printers with the autobed leveling. When I got it, everything was working fine, but I went and screwed up and updated the firmware. What I now know that I didn't at the time is that I wasn't suppose to do that. Since then, whenever I try to have the z axis home, it just moves up slightly. I think it's treating the two switches on the sides like the typical z stops. I've already checked and it appears all the wires are connected properly. The e-mail says there should be a revert button to bring it back to full working order, but it doesn't seem to exist. So if I'm correct in my diagnosis, I would like help reverting the firmware. If you disagree and think it's something else though, feel free to suggest that.

Firmware Version: Robo 3D R1 V1

 

Hopefully this is corrected by next week but you can get the latest firmware here. I posted flash instructions as well.

 

Everything's working well now, thanks.
