bricked MetaMotion R trying to downgrade from 1.4.1
I upgraded the firmware in a MetaMotion R board to 1.4.1 using the Metabase app. I then ran some custom code using the DFU library to downgrade to 1.3.3. I've done this before between 1.3.6, 1.3.4, and 1.3.3 without issue. The process seemed to go fine, with the library updating, but after completion, the board has been completely dead. It won't come up in MetaBoot mode, reset does nothing. Obviously, it's undiscoverable. I'm wondering if there are any hardware pins for reset or some other way to move forward with the, presently, dead board.
