Hey there guys I'm having a problem where my X button is no longer being recognized. I've tried the toothbrush method but that didn't help. So I tried to open up my system and managed to get 3 screws out before the other 6 refused to budge. Is there anyone who has had to deal with the screws holding the back of the system stripping? I'm looking for some general tips, or possibly someone who could could do it for me. My system is out of warrenty so I don't wanna go through the big N. Any help is greatly appreciated.
