I just bought a used Wii U to play around with and I think I followed the directions correctly and got CFW on it, HBC, etc... When I try to install WUP Installer GX2, it never shows up on the main menu. Not sure what I'm doing wrong. I'm going to clear off a spare portable hard drive tomorrow and plug it in to the Wii U and then see if I can install WUP Installer to it instead of nand.
