I have a 4.4.0-4J 3DS which can't run Ninjhax. Figure out that I need to upgrade my internet browser to version -7J to -20J instead of -4J. So I install pasta cfw by msett and run it on SysNand then I uninstall Japanese browser and install tittle 0004003000008802.cia v4096. Reboot and still -4J. So any step above is wrong? plz show me the right way, thankyou all!
