so long story short, i got a cfw 3ds form an online store, in the description it says "no need to open fbi" and i didnt really opened fbi cause i can download the games through the default file manager. i knew i had luma installed but i tried to open homebrew it doesnt work, but i dont really want to mess up my 3ds, cause i messed up a while ago downloading godmode9. and i wanted to use the scan qr code feature on the fbi (my internet is slow)
