MMU Unresponsive and cannot downgrade firmware after 3.0 update

I updated my Mk3S+ with new firmware and then update my MMU2S to new 3.0 firmware.  It made a stepper motor noise for about 2 seconds and turned off.  Now no lights turn on and will not accept new firmware.  Please help

Bonjour, j’avais le même souci et je l’ai réglé avec la dernière mise à jour du driver :

I had the same problem.  Downgraded both the printer and MMU2s to 3.12.2 fixed the problem.  Good luck.
