Wii not updating
The term is often used in situations where modifying a system's firmware (without necessarily making any alterations to the machine's hardware) has caused it to become inoperable.
A Semi/Partial Brick occurs when a System Menu update from the wrong region is installed on a Wii or some resources have been otherwise damaged, breaking some (but not all) of the functionality of the System Menu.
To brick a Wii is to damage the console beyond repair - as in 'A bricked Wii has all the electronic functionality of a brick'.
To put it simply, fully bricked Wii consoles do absolutely nothing.
Requires: In order to use a NAND Programmer/Infectus to rewrite the flash directly you will need to know your Wii's NAND keys.
Go to the HBC via Preloader, then select Launch Boot Mii from the main menu.Requires: It's advised to backup your NAND right after you install Boot Mii.If you installed Boot Mii as boot2, then simply go to the second options screen and choose the second icon which can recover from the brick.) Requires: Simply boot a recovery program the way you would any other.if you have Preloader installed, but it boots to the System Menu then try holding down reset when you turn on your Wii, after a few seconds of holding reset the Preloader menu should appear.
