FBI injection unfortunately dont works: the process goes rightly (i use right file for my region and TMD) with success notice on screen (press A lastly), but at the reboot i have no FBI in sysNAND instead of Health etc., neither if I launch rxTools in sysnand from his option menu. I think i'll try with PBTwith the PBT : because you can't run the PBT on emunand...
with rxTools : because rxTools let you choose if you want to install it on sysnand or emunand.
