Thanks for the guide! Even though iFixit doesn’t have the replacement parts, I was able to fix my button that was off-center and get my controller back up and running! The only issue is that with step 5, the T5 screwdriver that comes with the iFixit tool kits doesn’t work, as it’s too wide. I had to go out and buy a narrower driver, but still much less expensive than the controller. Thanks again!
