I'm having a strange issue with my 3DS. I was preparing it so I could install arm9loaderhax, constantly turning the 3DS on and off because of an issue I was having with BootCTR and then suddenly the touch screen at the power off screen didn't work. I thought it wasn't serious as I was hastily pressing the screen and thought that I pressed it too soon. Then I gave up and wanted to play something so I turned the console on. As suddenly as before, I noticed the buttons (except A and B, didn't test X and Y, they're probably working) and the Circle Pad didn't work as well! So I thought and still think, maybe the power button did this? My 3DS is pretty old, but it was working perfectly before this happened! Is there any way I can fix this problem?
