After successfully (at least it seems so) downgrading my 3ds using my gateway, my back up roms are no longer working. Specificly, I can now boot without the browser exploit, but when I get to gateway mode and press the select button no game manager pops up anymore. I've tried adding different roms (though what I had worked pre-downgrade) and every button combination i can think of. I'm running the 3.4.1 ultra. What am I missing and how can I go back to choosing my games?
