Help - I did a bad firmware flash
I have the Prusa MK3s and MMU2, I flashed the printer to 3.14 - no problem except it needed an update to the mmu2 firmware(3.0.3). the instructs to flash the MMU2 were the same as the printer. Now I have the wrong (MMU2) firmware loaded on the printer. Rebooting just shows 2 bars of blocks.
Pressing and releasing the "X" button then long press on the control knob does not do anything
Have I bricked it?
