Chosen Solution
Um so On my controller I was able to open all the screws except for the bottom left which I pretty sure is stripped. Can someone help?
It’s not stripped the head is rounded out. It looks like it takes a allen wrench. Try wrapping the head of the allen wrench with cellophane/plastic wrap to help fill up the area around the wrench head and try it. Or you can try the metric size or standard size which is whichever is not the regular size wrench. The slight difference in size can make it grab better. The last choice is to drill it out
