Ive just broken 2 sps trying to do this. I have tried to follow the other guides, but would feel comfortable with a more in depth step by step guide. My friend is giving me another one so can someone please make me an in depth, step by step guide or video on how to do this? I would like to use the original dmg controls, dmg power switch, but I want to make holes for the left and right shoulder buttons. I have dealt with solder before, but can someone make the guide noob friendly. I would be willing to pay for a guide.
