I recently found this tutorial on youtube showing me how to downgrade my wii from 4.1 to 3.2 (3.2 being the best version for homebrew).
download the file with the word downgrade. ignore the other one. Free File Hosting Made Simple - MediaFire
follow the video exactly (except for the update part)
i created a youtube channel just so i could post the video on this site. i hope your happy peoples :D enjoy!!!!
