I'm trying to figure out how to replace the battery circuit board tho currently , if anyone might possibly know....maybe ... lol

There's a dude on YouTube goes by ima_rainbow who fr does a kickass video tutorial on this if ur still needing one , or if anyone that sees this is looking for one. Dude was the only reason I choked up the courage to open mine up but ifixit (amazing site js fr lol) was the only reason I got the balls to attempt opening up the headset itself actually, when it got stuck in a bootloop

Break it if it's already broken so. Plus if ur having to get to this point because ur $@$* won't work wat else do u gotta lose lol at least that was my mentality.

The ribbon cords that r warned about at the end of this marked by the blue arrows , in case anyone else ever goes thru wat I did at least , over time have a possibility of popping off the circuit board (well the connector for the ribbon cord technically, meaning the cord is in the connector also js) and it will cause the controller to basically vibrate over and over and over plus not track since those r the ribbon cords for the sensors that go along the ring. And if this is something that happens and ur like someone like myself who doesnt own a soldering iron dont go running to buy a new controller, and I'm sure theres probably plenty of people who will look at this and say I'm fukn with people when I say if u have it at ur disposal just simply gorilla glue it back on. Obviously it doesnt need more than a drop of it but as long as u line up the popped off connector to where it should be which isnt hard and let dry rq its highly likely ull get it working again. Dont believe me well u can try it not like u can
