Homebrew I've homebrewed my N3DSXL 11.9, but I can't use FBI

[ErsanDersan]

I used the Steelhax method and heard I need to use some other form of CFW to use it... any help?

Only Steelhax? This is userland homebrew -- not enough for full system control (FBI needs more privileges).

Continue with the Frogminer guide on top of Steelminer to get boot9strap(B9S) and Luma CFW.

Frogminer guide will send you to the finalizing setup page at the end. This will get FBI (and some more things) installed.
