Updating Wii Menu to v4.3

For support in English, ask for help at Nintendo Homebrew on Discord.

This tutorial will explain how to update your Wii Menu to version 4.3, if you have already homebrewed your Wii.

It is much safer to use ModMii (Windows only) to update your Wii to 4.3.

Your Wii must be modded in order to perform this. If it isn’t, then it’s best to follow the guide first.
