My Wii says " The System Files are Currupted" Can I fix it?

Question

I have the Wad manager installed in the homebrew and messed it up with a wad. Can I fix it and with or with out a mod chip? Thanks!

Answer 1

If The System Files Are Corrupted Call Nintendo About It If you Still Have A Warranty You Can Get It Replaced.

Answer 2

The only thing I can think of would be formatting your system memory if you can access that.

If not, it's more than likely possible with a modded Wii, but I can't say I'd know how to go about fixing it.
