I've been out of the homebrew scene for a bit, and I recently got asked by a friend to help him out with his Wii. Seems things have changed since then with this 4.0 stuff. After lurking around, I've found out that you're pretty much screwed if you didn't have the HBC already installed. Well, the bad news is my friend is one of those people, so he is on 4.0 without the HBC. I haven't found an exact answer, but is there NO other way to downgrade? Even by formatting the Wi system memory, does that not effect the firmware of the Wii? Thanks for the help.
