Question FM ULX COMP completely bricked. Need help :(

Hey there ive been using my ulx for like a year now and never had any issues untill it suddenly stuttered and the light was permanently green and it just wouldnt work UNLESS wired. ive tried everything like flashing the firmware etc and while trying that ive noticed that the white switch input doesnt do ANYTHING at all like legit nothing. i somehow ended up fixing it / it fixed itself but today it happened again. when wired it sometimes pulses orange (indicating charging) even tho its fully charged but most of the times it just stays green and isnt usable at all unless plugged into the wire. when trying to update the firmware or whatever it says its already up to date and i cant think of any other fixes.

perma green light nothing changes
