Hey I have been doing allot of searching and I keep coming up with mixed tutorials and methods. My wii is a USA wii and is currently at 3.1U. I keep reading about having to do a cIOS install before upgrading to 4.0. My drive is also chipped if this helps. I have found a site with a blue background that appears to have all the files necessary for getting it up to par. I need to install cIOS rev 10 before I upgrade correct? This is what I think I will have to do: 1. Install cIOS rev7 using a "4.0 softmod pack" 2. Upgrade to cIOS rev10 3. Check to ensure bannerbomb is working 4. Upgrade to 4.0 via wii shop channel ? 5. Use banner bomb/bootwii to install homebrew channels? Can someone please direct me to a full tutorial for a correct upgrade to 4.0 with all the cIOS properly done? Thanks for the help!
