Hello I have a Nintendo 3DS which has problems when pressing the Y button. I noticed that these problems seem to be caused due to the metal pads for the buttons situated on the motherboard as seen in this image: https://d3nevzfk7ii3be.cloudfront.net/igi/Ql2QL1iOEaeAbBlw.huge I ordered a few ones on AliExpress recently: http://www.aliexpress.com/item/10SE...it-PCB-Pads-for-Nintendo-3DS/32521453683.html Has anyone did this before? I found there's a sticker on the board where the pads are but if I lift it, it doesn't seem to bring the metal pads there. How can they be removed so I can put a new one? By the way. SOme screws are about to strip. Do you know where can I get replacement ones? Thanks!
