A while ago, about two years I guess, I hacked my Wii. Had it successfully running backups. It all turned to shit when trying to run a MHTri backup and I hadn't been able to get it working. I left my Wii collecting dust for a while. Recently I hacked a mate's Wii, got it working in 20 mins no sweat. I'm wanting to get mine sorted out again, and figure that rather than contending with all the bullshit I've already got on there it'd be loads easier to start with a clean slate. Googling and forum searches haven't turned up much, but is there any way to basically restore my Wii to an unhacked state.
