I had 3.3u & Followed this guide & now my wii he messed up. I got all the way to "Install Shop IOS51" and it went thru after it said complete my wii froze. Now everytime I go in the homebrew channel all I get is a black screen and my we freezes again. I tried to uninstall the homebrew channel and reinstall it but still freezes when I go into it. DO NOT USE THIS GUIDE! It will mess everything up.
