Remarks

If you have a System Menu below 3.2 and wish to upgrade, use AnyRegion Changer to update.

WARNING: Be advised that if your system is shipped with 4.0 preinstalled, you can not downgrade and will brick your console.

If you have a System Menu above 3.2 and wish to downgrade, AnyRegion Changer can do this too, and it appears to do a more thorough job than some other tools. See WiiBrew:FAQ#Downgrading?.
