Hi, I can't run any DS/DSi content since I installed the patched TWL_FIRM from that iso site on my 10.7 sysnand (I'm using AuReiNand + A9LH). I reinstalled the original TWL_FIRM but still doesn't work, when I launch a DS catridge or DSiWare the screen stays on but black and with the music from the home menu. How can I fix it? It's an O3DS. Thank you.
