New here - thanks for adding me.
Just bought a 2nd hand LXR and can't get the firmware to update. It gets part way through and freezes; the screen goes blank and LEDs stop moving.
It seems that one of the pins to the screen is missing (ins from left as you look at the unit) - not sure if this could cause the issue?!
Other than that, I have checked all joints and they seem OK. Reflowed a few; no change.
Is there any advice anyone can give me? Should I just keep checking joints?
