yup, latest version (1.11, right?)
http://pokemonmegagenbr.com/desbloqueio-de-3ds/ this one, its a brazilian guide, but i'v already use it like 6 times.
Im on my last step to cfw my 3ds, i just restored my sysnand with a9lh, but when i try to inject FBI on H&S it says:
No usable file found
Health&Safaty Inject: Failed!
Am I missing any file? This never happened to me :/
