Hello. I had a broken controller after i dropped it, and i ordered a replacement.
So i was thinking what if i can fix it, and i found the problem. touch pad flex cable was damaged, i removed the connector and the flex cable and soldered 6 wires in the place. image1 https://gyazo.com/d924fadcf1b45911693e52ce52a14069
Firs contact support before you attempt this, i am not at fault if you fail and break it completely.
Attempt this at your own risk.
