Nintendo 3DS Malfunctions

So recently, my Nintendo 3DS started malfunctioning. I was playing a Need for Speed game, and after a while of not knowing what the problem was, I finally figured out that the L button and control pad was sticky. What I mean is, the L button acted like it was pressed down, and the control pad's left and up buttons acted like they were pressed down. So I went to one of my friends for help. What he suggested was wiggling the L button and control pad. I tried it, and eventually the R button started acting like the L button, and the A, B, X, and Y buttons stopped working, as did the home button. Now, every time I turn it on, I get a glimpse of the menu, then it automatically goes to the camera. I try tapping 'Quit,' but after it gets to the home menu, it reloads the camera. Any suggestions on how to fix? I would at least like to fix the L or R button so that when I buy a new system, I can do a system transfer. [asking fellow bronies, so please do not report me]
