Hi, I have been looking around for an answer to my problem and so far am struggling for one. I have an O3ds running Ver.4.3.0-4E, I have a hard copy of cubic ninja and want to install Ninjhax, I have tried the QR codes but the install stops on 70%. I dont get why I am having this issue of Ninjhax is supposed to work for versions 4.0.0-7 to 9.2.0-20 E/U/J? I have read around this problem and it looks as though some people are saying I may need to upgrade to a later version of the 3ds firmware. Is this really necessary? Should I do this or will that stop me from being able to install homebrew/ CFW? Basically all I want to do is install Ninjhax, then Pasta CFW maybe afterwards. What is the best way forwardwith this? Any help is appreciated. Thanks
