I meant using Ninjhax to install, but I guess the above should help more people
So using FBI through pasta CFW and install mset 4.x using the install mset option, then using rninstaller to install the ROP chain before launching DS profile. Am I right?
Fairly sure you only need to install the Bluecardfix.cia with Pasta>FBI then rninstaller 4.x N3DS with the NDS flashcart. After that yeah normal profile exploit.
