I want to hard mod my o3ds xl with the latest firmware.. As far as I can tell I can.. I have a few questions though, what do I do to block updates, my wii u had dns tube, and another and Nintendo updates are blocked via my router for the wii u, do I just use the same dns, cause the blocking did not work on the 3ds.. After I get to 10.4 hat do I do next, for cfw, installing games, etc..
