Hardware Is it possile to do a 'clean install' on a Wii?

[SG]

I'm fed up with my Wii not being able to use Accio Hacks and Cheat Manager only sometimes working... with only 1 code, and generally not loading sometimes for no reason at all.. So I was wondering if I could reload a fresh copy of the OS on it somehow? It's on a hacked 4.0U with latest HBC installed but it's always been like that on other menu versions so I don't think upgrading will help and apparently 4.0 is a better choice to have over the newer ones.

Can anyone help?

Wow, thanks - that looks like just what I need. I'm not sure that I'd be able to do it all myself; for instance what is the NUS? :s

NUS = Nintendo Update Server. NUS Downloader is the program used to grab the update/system files from the NUS.

Brilliant, thanks! I'll see if I can get this to work. :s
