I have my New Nintendo 3ds XL. It's circle pad had its rubber grip ripped off before I got it and I wanted to replace it. I open up enough to reach the micro sd card slot. However I cant get past the 8 screws to reach the motherboard to get to the circle pad. The 8 screws wont budge at all, and I don't wish to strep the screws. Can anyone help me figure out how to unscrew them without having to go to a mechanic or send it to nintendo. (I have a replacement blue circle pad, and I dont wanna pay $80 along with shipping) Any help is appriciated.
