ok so im looking at this https://gbatemp.net/threads/tutorial-installing-rxtools-custom-firmware-3ds-and-2ds.390867/ so i dont have gateway or cubic ninja so i gotta do steps
1 1-7
then skip to step 2
step 3 then 4a?
im i little confused as there are other instructions and im not sure where they end
Yeah, I believe it's exactly as you said. Just follow the ones that you actually can do. The stuff about GW or Ninjhax you can skip since it's not for your case.
