New MMM won't update

I picked up a new MMM. Plugged it in with castle link and it said new firmware available so I tried to update the firmware and it got an error during the process. Now it won't do anything. It will read but will not write, when I plug in batteries I get nothing. I tried reverting back to older firmware and get errors while updating firmware and trying to write. I haven't even ran the esc yet, first thing I did was plug it in to adjust the settings.

When I try to write I get this error. "Error communicating with device: Did not receive a response from controller. Try unplugging and reconnecting USB device"

When I try to update firmware it just said updated failed try again.

I tried both my computers, both front and back USB ports and 2 different clink adapters.

Any Ideas?
