Okay so I have a 3DS and I am willing to downgrade to 4.5 if needed. So, I want to install Rxtools or any CFW that supports unsigned cia so I can run backed up games that I already own. Now, when I go to the turorial for installing rxtools, you need cubic ninja... Is there anyway of installing cfw WITHOUT cubic ninja? And also can someone give me or give me a link with clear steps as to how to install a cfw emunand. Thanks! I have an old 3ds aqua blue!
