I turned on the printer today and the heat bed is showing -15 degrees and blinking red. I unplug/re-plugged it back into the buddy board and downgraded to 4.01 and back to 4.03. Any time I try to do anything, I get a watchdog reboot. Any advice?

Thanks

It is possible that sensor is bad, or wires broke. Not uncommon with MINI. https://forum.prusaprinters.org/forum/hardware-firmware-and-software-help/pictures-say-more-than-a-thousand-words/

I've checked the wiring, tried using a different thermistor port and making sure the connector was properly plugged in, but to no avail. The fluctuations are brief enough that they don't cause any problems when printing.

Are you replying to the correct thread ?
