hello i tried to install b9s CFW to my 3ds 4.0.1 and i exactly followed the orders of 3ds.guide then an error has occurred after i completed part 3 of section iv and error says (failed to get the ctrnand firm) even website itself says if you get an error just go to next page but next steps need to boot 3ds and go to setting and update the system which in my case i still get that error. i searched google but there wasnt anything clear which can help me solving problem.
