I have a Wii that was refurbished by GameStop. I tried installing BootMii using letterbomb; I inputted the mac address and put the correct version (4.3U). When I tried installing it, it said that there was something wrong. I then tried installing the hackless version of project m (as that is why I'm trying to install homebrew) but even that didn't work. Am I doing anything wrong? Is there anything I can do to fix the problem?
