My 3DS has been sitting on my dresser for months so nothing has changed until now. It worked the last time I used it as well. When it starts normally an update message would appear. Now it does not, the A button does not select things, and nothing will open and if I try it crashes the system. This is similar behavior for when my sysnand is starting up and the update message hasn't popped up yet leaving me to believe it is something to do with the prevention of that prompt. My other sd cards with clones of the same exact emunand work fine. How do I fix this?
