So I've previously had a new 3ds XL and 2ds CFW, but that was all the way back during the 9.0 downgrading days. I recently received a new 2ds XL and thought I'd throw a CFW on this too. Now the real question is that I've read up on the B9S flashcart, but all guides I find about it are mostly about 11.6. Does this also work on 11.9? Cause it seems pretty braindead to do with just insert the flashcart, throwing ntrboot on your own SDcard and then just flashing it.
