Part 3: Installation

Modmii

1. You should see a scam warning onscreen, if this was successful. Wait for thirty seconds, then press 1 to continue.
2. When at the HackMii installer, press Continue > Install Homebrew Channel and wait for it to install.
3. Once installed, go back and install BootMii
- If the screem says you can install as boot2, do this, this heavily protects your Wii from ever bricking.
- If your screen says otherwise, install BootMii as an IOS. This doesn't give you as much brick protection as a boot2 installation, but it still allows NAND backups.
4. Once this process is done, exit this installer.

You have several options now.
