I have done many installs similar to this type of thing, but this is only the second controller I have installed, Now I know how to solder to traces and via holes, I have fixed CB Radios, and even made things like mini tasers. my knowledge on xbox controllers is most likely no where near yours fedrow or any of the moderators on here, but I know how to solder, and I know how to not apply too much heat. I am also not saying that it is anyones blame, I just get pissed when people say I don't know what I am doing. I would not have gotten a diy if I couldn't do it. Now, I know I bought this in November, and when I got it it was in a flat box, more like a folder not in a 3D shape so there was nothing to protect it. And the box was a little beaten up.... That might be where the problem is. I also know the mod chip is not totally screwed, because only 2 buttons don't work B and RB. Fedrow, I am not going to take you up on that bet because you know much more about the xbox controller and the chip its self. I only have what the instructions say to go buy. I have tried multiple locations for both the B and RB buttons. If you would like I can send it to you, but because it still works... for the most part.... I don't want to just give it to you.
