My Wii U doesn't boot properly. It has Cold Boot Haxchi and Mocha installed. The problem appeared after installing a repacked game on the USB (Super Mario 64) following the threads on GBAtemp, using NUSPacker and WUP Installer GX2. The installer said that the installation was successful (I have used it before) but when pushing the Home button the console froze so I held the power button pressed to turn it off. When I try to turn it on it's stuck on the loading screen before the Wii U Menu (Wii U logo, then white screen and sound loading the Wii U Menu, then black screen and white screen and sound loading the Wii U Menu again and so on) as if it was not able to load the Wii U Menu. I tried to press B (to load the vWii Menu) and Home (to open the Haxchi boot menu) but they don't work. I don't have a NAND backup. I have tried unplugging the console for half an hour, remove SD, USB and disc. I don't know what else can I do to try to fix it.
