When my old 3ds was on 11.3 I downgraded using A9lh through home brew sound hax. This got me to 9.2.0 then I downgraded from there to 2.1.0 God knows how I did it. And me being a noob and not knowing how to install a CFW even with all the guides I just updated but I didn't even know that 11.4 was out . So now I'm left with no homebrew. My 3DS is FINE except the fact that now it can't play DS games, only 3DS games it can play. When I launch DS games on it, the screen goes black and the home menu music is still playing but at a low volume... Its been 4 months now... I'm thinking of just getting a new 3DS. Help??
