<summary><em>Technical Details (optional)</em></summary>

We use BannerBomb3 to install menuhax67, which lets us access the Homebrew Launcher. From there, we launch nimdsphax which launches SafeB9SInstaller. 

See [here](https://github.com/luigoalma/nimdsphax) for information about nimdsphax and [here](https://github.com/zoogie/menuhax67) for information about menuhax67.

1. If the exploit was successful, your console will have booted into the Homebrew Launcher
1. Launch nimdsphax from the list of homebrew
1. If the exploit was successful, you will have booted into SafeB9SInstaller
