Is there any way to "unhack" my wii?

I don't see the big deal, there are some nifty uses for homebrew.

Update it with Nintendo, I'm guessing that will delete all the HBC stuff. Or go into data management and delete the channel.

Otherwise, you could try this. May be risky though.: http://sites.google.com/site/completesg/other-stuff/virgin
