Help updating Wii to play newer games and from USB source

I was looking at thisTHREAD and wondering what if anything I could take from there and apply to my Wii. I have a hardmodded Wii (Wasabi chip).

Any help, directions, or tutorials would be much appreciated. Very informative site, thanks to all.

[Edit]

I already have the HomeBrew Channel installed, but it's been a while since I've used it or updated it. My Wii is currently running 4.0U. Mainly looking to run newer games off USB thumbdrive or HD if possilbe.

Use the mod any wii guide. That is a old unsupported guide. Introduce yourself and you will get lots of useful links including one to the guide mentioned.

Do not update via Nintendo!
