since i had nothing better to do, i thought I'd see if i could get fbi to work at all, but like a few people in this thread, i've never gotten past the Done screen. i mean, i got into fbi when it stuck at cleaning up, but never the way its supposed to and stuff.
i tried several of the tricks and several things of my own, like copying all files to pc, formatting the sd and putting the files back, with boot and fbi being the first files on it and stuff like that.
i wonder if it isn't like, certain models that just work a lot better than others, or if the sd card reading and writing speed aren't all somehow a part of this mystery. considering some easily got this to work several times in a row or constantly while others struggle endlessly. maybe some consoles come with ram thats slightly faster or slower and that maks a difference when this exploit tries to execute.
basically the same way some report menuhax to fail more than half the time while for others, it never failed ever.
or if the console is preoccupied checking street pass data in background (if thats even happening while homebrew launcher runs). just less obvious stuff that might interfere.
because as far as i can tell, it doesn't seem to be what version of 3ds you have, what exploit you use, what version of exploit, even what homebrew menu you use.
but it also doesn't seem to be absolutely random, since for most people, it either works somewhat reliably, or barely if ever
