I wont to install on a unchanged WII with firmware 4.0E HBC. I ask me if i should update before to firmware 4.2? WiiBrew.org say "WiiBrew recommends that you do not update your Wii through Nintendo." But on the linked video Homebrew in 5 minutes they update the wii before. Is it ok to update the wii actually through nintendo that i can use HBC and all the other tools or do you know problemby blade - Getting Started
