--------------------- MERGED ---------------------------
Anyway I found the regionthree which can run without cubic ninja at 4.x, I think the regionfour does not work for me since it requires cubic ninja as well, so I am not sure this will work together with the pasta cfw ot not, have somebody tried it, please share our help me solve thissolution, thank you guys
Why are you trying to use Cubic Ninja? You have a 4.x 3DS, so you shouldn't need it.
See this thread: gbatemp.net/threads/release-pasta-cfw-without-cubic-ninja-mset-4-x-old3ds.389498/
Otherwise, if you were on 9.0-9.2, using regionThree would be easier, because all you would need to do is run it from the browser. You can't do that with 4.x, but that's okay because you have a fully exploitable version of system settings.
