Before I start, I am not a noob. I have had the twilight hack for a while. I use homebrew channel a lot and know what it is. I want to know how I can upgrade to 4.0 with my homebrew channel still installed. I am on 3.2U and I am not sure what cIOS is much but I upgraded it or something when I installed backup loader 0.3 gamma for my broken Wii Music. I have homebrew channel already and all the tutorials I went too tell me to download it. Can someone explain how to go to 4.0 from here? Do I upgrade normally?
