Hello, a few days ago I bought a used Wii from the internet. The former owner told me he used to play games from original dvds and had no hack or anything. I went to the wii system menu screen and the firmware version is "4.3U wan.". In the main menu screen there is no Homebrew channel only disk, mii, photo, wii shop, forecast and news channel. I tried to use letterbomb to install the homebrew channel, but when it starts an error shows up: "The installer can NOT continue! There is no vulnerable IOS installed on this Wii..." I dont know exactly what to do, some places say I can brick my Wii if i try the wrong hack. Does anybody know which options I have to fix my Wii?
