These instructions will assume you’re using an SD card to mod your Wii with, but you can use a USB storage device instead. However, the exploit LetterBomb requires a SD card due to how the Wii Message Board works.
This guide is for the original Wii only, with the latest firmware (4.3). Do not use this on a Wii U (vWii)! If you want to install homebrew on vWii, follow this tutorial.
Choose an exploit to use
- str2hax - Exploit that uses the Wii EULA (No SD Card nor Channel required)
- FlashHax - Exploit that uses the Internet Channel (No SD Card required)
- LetterBomb - Exploit that uses the Wii Message Board (SD Card required)
Some alternatives to this guide are ModMii (if you have Windows) or SetMiiUp. Both of these allow you to get started via a guide, however they do not install other services by default, which this guide shows.
