I had to hardmod my 3DS because arm9loaderhax suddenly stopped working. I've managed to restore a NAND backup and the 3DS is now working with firmware version 6.3.0-somethingE, however, during reassembly, I accidentally broke the R button flat cable. I know I can buy a replacement, but I thought about fixing it by soldering wires to the test pads. Can someone tell me where I should solder them? EDIT: I found the pad for the R button, and I know it has to make contact with the ground to activate. However the "button" has got 3 pins on the back + 2 on the sides. I tried attaching the wires to some of the pins but it didn't work.
