boot HBL, run minipasta, boot hbl again from minipasta, run fbi from hbl then install bluefix.
Or you can install Devmenu from there if FBI should complain. But you need to boot to minipasta to launch devmenu.
There's no real need to inject FBI to H&S since you'll most likely only do this once.
The blue card has a OS of sorts that you put on the SD card in the blue card. it should consist of folders like _rpg, moonshl2, and some files on the root. This is the OS of the blue card and if left blank it cannot do anything. These should come in the GW rar. I think what I use is from R4 cards specifically.
So...I followed an RxTools guide on this site and I've installed emuNAND usefull cias and stuff (thorugh a new sd card) and I installed the cia that was included with that tutorial and now I'm able to use the R4 clone (to get it recognized by the 3ds system,at least, it load leaving an error that the system must be shut downed) whereas the Blue Gateway isn't recognized at all
*Edit*:Just trying it like 4-5 times ''fixed'' it bu now stuck on loading.. screen :/
Really dunno what's wrong sorry for being irritating
