I completed it. And out of the whole process I only stripped one screw. :D Sooo I just unscrewed everything else and tore off the back. Anyway Mission complete!
I got it apart and put it back together. The A and B still don't work however. I've never done anything to this extent before so it's probably my fault. But the problem may also be beyond my repair capabilities. I will likely try again. Also for some reason my sound doesn't work. I suspect it is not the actual speakers but something else instead. Oh well. I'll get a new XL and take better care of it!
I've come to the conclusion that my a buttons contact has given out due to the fact I have to force it for a response maybe that is what happened to yours
ok. so i managed the tear down as an experiment in seeing if i could do the process without destroying anything and i had complete success! now the problem is finding a replacement for the "select, home, and start" laminate buttons on the front of my 3ds ctr-001. can anyone provide a link? google and amazon are of no help.
I damaged the part of the socket, is there anything I can do to fix it?
