What happens, in a nutshell, is that whenever the console boots up, it doesn't make a sound, but the little lights that show it's turned on light up. If I boot it up without the SD card, nothing changes except it actually makes some noise.
Using the good ol' L+R+A+Up on the D-Pad while turning on to boot up safe mode makes the console turn on properly. HOWEVER, it still doesn't change when I try to update the console. It says the system is up to date and turns off. Booting the 3DS back up still has the same results of a black screen with no sound. I've tried this over and over again, with different SD cards and nothing seems to fix it. Is my 3DS done for?
