I just got arm9loaderhax, and back when I used menuhax, I had a patched TWL firm so I could play with my R4. I installed the vanilla twl firm so I could downgrade and get otp. Flashfowrd, When I finally got through everything, I tried to install it again after copying emunand to my sysnand, I didn't work, I tried to remove it, but I think I deleted another file, so my 3ds bricked and I had to restore it from decrypt9 (I love this thing so much!). And then I tried a ds game, and it didn't boot at all! I said, error ocurred, and this is before I had installed the patched twl firm!. Then I tried just deleted the twl firm with fbi, and yet again installed the original official version with bbm, this time it didn't brick, but I can't even play ds games! Can someone help me atleast recover ds compatibility?
