[SOLVED] I installed A9LH and luma, everything was great. There was rainbows and unicorns everywhere. One day, my 3DS started refusing to boot to NAND and EMUNAND. I can still enter the menu and Hourglass and the other stuff. Just not NAND/EMUNAND. Since I was in the 6.3 version of Luma, I tried downgrading to the old arm9loaderhax.bin.bak file. I tried using another SD card. I tried to inject the emunand in my SD card to the NAND. Nothing works, it simply won't boot I ran out of ideas, could anyone lend me a hand, please EDIT: Forgot to mention, when it tries to boot the nand, it goes to a black screen but when it tries to boot emunand it says: EDIT 2: SOLVED! It was actually my R4i DS cartridge that somehow was preventing the NAND from booting, I took it off and know it works perfectly!
