How to Prevent Wii Updates
An accidental upgrade is most likely to happen if you play a game that includes an update check and you haven’t disabled the Wii’s update checking. You’re notified when a new Wii update is available from Nintendo, but you can refuse to download it. If you don’t refuse, your Wii updates to the current version and your Homebrew Channel disappears.
How to Get the Wii Homebrew Channel Back
First, you need to know what version of the OS you upgraded to. The Wii’s final update was 4.3. To find out what version of the operating system you have, go to Wii Options > Wii Settings and check the number on the upper right corner of that screen. That’s the current OS version. Now, you need to reinstall the Homebrew Channel for the appropriate OS. Read the Homebrew Channel installation guide to learn how to determine which homebrew package you need and how to install it to your system. The below instructions work with OS 4.3.
How to Uninstall the Homebrew Channel
Remove the Homebrew Channel from your Wii by deleting it with the channel manager in the system software.
What Is the Homebrew Channel
The Nintendo Wii Homebrew Channel is for launching fan-developed homebrew applications on the console. After it’s installed, it appears in the Wii System Menu, where you can use it to easily install homebrew applications. The Wii isn’t designed to support homebrew apps, though, so occasionally users update their operating systems, not realizing this results in the loss of the Homebrew Channel.
