Possible Bricked Board

Was told to make a new thread for this.

Its been 1 step forward and 2 steps back with this project. I ordered and installed a BLTOUCH which functions, but throws errors. I now reflashed it with the TFT screen plugged in and not it no longer detects the printer. The auto test function on the SKRv1.2 still works so Im not sure if something happened to either board when I didnt unplug. Now it doesnt see the printer. I reflashed both with the default firmware and have the same issue. No wire changes occurred, but it is pretty cold in the room its in if thats relevant.

Any thoughts?
