This happened awhile ago but I never tried to fix it. I used to be able to go directly from bootmii to the homebrew channel, but after updating the hombrew channel that stopped working. When I selected it from the bootmii menu, the screen would go green, then black... but the channel never loaded. Later on I accidentally deleted a file related to bootmii off my sd. So now I have no bootmii. I'm on 4.1U if that's at all relevant. What files are required for me to load bootmii? Once I get that working, we'll see if I still can't load HBC from bootmii. Any help would be appreciated.
