Well, I have no idea then xD
I'd recommend you to create another emunand from zero, but that would require to lose all your games' save data and Nintendo Account...
If the error persist even thought after you changed to Luma, it could be a bug of the CFW as a whole...
I never heard of this problem, so perhaps it's something else. Do you have a backup of your emunand before it started to act strange?
Nah, forget it. I updated my 3ds to A9LH, installed Luma and the patched AGB_FIRM again. Now it works flawlessly.
Guess I needed an update sooner than late, huh.
This, then report us what happened.
Besides, you don't have any kind of CFW in your 2ds or whatsoever? If yes, you could patch TWL_FIRM for boot DS blocked cards, or just use Luma 3DS that patch it automatically.
Nope, Black screen error still happening.
I came to the conclusion that the games didn't install well since these aren't shown properly on Sysnand, but again, I don't sure what titles I should delete.
Man, I just wanted to play FE7...
I have Luma 3ds, and both Sysnand and Emunand are unlinked.
When I try to boot the game on Emunand it does what is described in the title.
Yes, I installed the Cia in both Sysnand and Emunand, besides of patching the AGB_FIRM as this post describes of course.
Do you think the error comes from...
I've installed Luma 3DS and now it runs, but it'll be stuck on a white screen forever. Plus the DS Card Icon on 3DS is always a white card icon instead of an actual game.
I think my card is bricked. I got it from a friend of mine without to much information beforehand, so he might bricked that...
