I opened up my controller because I had sticky buttons. In order to open up a xbox 360 controller you need to remove some adhesive from the battery pack to get to the hidden screw. I ripped it off into a couple of pieces. I fixed the buttons and I put my controller back together. But now I need to find something the same size to cover up the hidden screw so my warranty won’t be voided! What can I use to cover up the hidden screw so it will look like I never took off the adhesive in the first place!?
