I updated my Wii to 4.0 using this link http://gbatemp.net/index.php?showtopic=144835. When I placed AC:CF in the Wii, it told me to update, and I did. Now I'm thinking of putting NeoGamma backup loader, but I'm not sure if the AC update changed an important IOS or something. So, did the update do anything drastic to my Wii that it may get bricked if I install more homebrew? If so, what do I need to do to undo it? I'm afraid that if I install new IOS for the loader and etc, my Wii will brick. Thanks.
