Somehow during the course of upgrading to 4.1U the HBC loads to a black screen. I can't uninstall any cios or anything since it doesn't work. I tried reinstalling using HackMii + Bannerbomb to hope it will fix itself but I get an error in the middle of the installation. My USB loaders and disc loaders work, but I need to access HBC to install the latest loaders. Anyone have any advice or suggestions?
