So I was just given a Nintendo Wii by a friend. He said that he bought it off a Walmart and that it stopped working after a while. So the problem with it is that it gets stuck on the Health and Warnings screen and doesn't go any further. I tried pressing the reset and A button while it was turning on and it brings me up to this white screen. It says IOS v80, System menu v513, priiloader v0.4 (r78) and in the very bottom it says Priiloader is a mod of Preloaded 0.30. I try to go to System Menu and it tells me "Error autobooting system menu! the going to load IOS was detected as Stub". I am led to believe that it has been tampered with, so I install homebrew using the Load/Install File option and run it, and I read some articles online that I might need to install system menu again using dop-mii. Well dop-mii has trouble downloading system menu because it was never configured to the internet. I can't get the Mac address to use letterbomb with because it doesn't get past the health and warning screen. I have no idea what's going on, can anybody help me? It's a US model by the way.
