I3 MK3 MMU2 upgrade fail, can I downgrade to original

I3 MK3 MMU2 upgrade fail, can I downgrade to original by disconnect the MMU2 cable or I just needed to flash the old firmware to disable the MMU2.

You can simply unplug the MMU and then treat the printer as the normal MK3 or MK3S depending on what you have. You do not need to change the firmware (unless you upgraded to the MK3S and want to go back to the MK3).

I upgraded to the MK3s as part of the MMU2S upgrade. It's a disaster. IR filament sensor works about 50% of the time, MMU2S jams constantly. It's just not ready for prime time. IF I want to downgrade, do I have to disassemble / reassemble the extruder again? Can I just keep using the "new" extruder? Do I need to change firmware to the non-MMU firmware for MK3S?
