Got blob. Then S1 won't level or print, and bugs out in various ways

Basically title. Got a blob which broke the thermistor. Replaced it and now the S1 Plus won’t print or auto level.

Auto leveling: The print head moves into position, moves down and up 1cm and then does nothing when you press “Start”. After a few seconds it says “I’m done leveling” and the screen freezes.

Fan speed: Change it and it gets stuck to 255, unable to stop.

Tramming/manual leveling: Won’t move into place when you press zones 1-5.

CR Touch: Probe moves down and up for a split second when you turn the printer on. Blinks red/purple in various ways after that but never moves.

Also, the print head will never go fully down to touch the plate.

This is a motherboard failure, right? I bought it from one of the MANY “official but convoluted web adresses” sites, and so, I’ve apparently never gotten a proof of purchase or anything. I just can’t find it on any of my emails for some reason. =/

Hep. plis.
