MMU2S Print Failure and Firmware Update Failure  

MMU2S Print Failure and Firmware Update Failure

I have a MK3S+ with a MMU2S that has been working fine for the last two years.  Recently I have been getting a failure on the MMU2S where all five LEDs flash green and red at the same time - this normally happens about 2 hours into a two material print.  I tried the rest button and then all flashed red (This was in the middle of a print, which the troubleshoot video says is not possible). I pulled all filament out of the MMU2S and cleared the flashing lights (manually reloading filament), but when it started printing again it used the wrong color.

I followed through the video on how to troubleshoot the five flashing lights.  I checked all connections, blew out all connections with compressed air, updated the printer firmware (MK3S_MK3S+_FW_3.14.1_MULTILANG.hex).  I tried printing after this and it when through the start of the print cycle, zeroing the bed, but it never attempted to load filament.  I then reflashed the MMU2S (MMU2S_MMU3_FW3.0.3+896.hex) and now I have three green light hold steady, one slow flashes red, the last flashes fast green.  The main shaft spins one way fast and the other way fast until it jams, then all lights go out.  The MMU2S's lights only turns back on when I hit the rest button but it goes through that whole process again.  It only responds to the center button on the MMU being pressed - the idler spins fast one way and fast the other until it jams.  The printer does not recognize it as being attached.  I recorded a video of the error.

It does not make a difference if filament is loaded (i.e. the finda probe is triggered).

Anyone know how to fix this?
