cIOS

{% include toc title="Table of Contents" %}

This guide will show you how to install cIOS (custom IOS). This enables the usage of USB Loader GX and WiiFlow. Some homebrew might also work better using cIOS.

If you have a Wii mini, use this guide for cIOS instead. Attempting to install other cIOS on a Wii mini will not work. {: .notice--warning}

Requirements

• A Wii
• An SD card or USB drive
• d2x cIOS Installer

Ensure that if you are using an SD card, the lock switch is in the unlocked position, otherwise you will not be able to select the correct options in the installer. {: .notice--warning}

Instructions

Section I - Downloading (Only required if your Wii doesn't have Internet)

If your Wii has an Internet connection, you may skip this section.
However, If you encounter any errors like tcp_read timeout and net_gethostbyname failed:, this will allow the Wii to skip the downloading step. {: .notice--warning}

If you are not on Windows, you may download & run this script, and it will download the WAD files for you. {: .notice--info}

1. Download, extract, and run NUS Downloader.
2. Select "Database", "IOS", then "IOS38", and select "v4123".
   • Ensure that "Pack WAD" is checked.
   • Don't check "Patch IOS". That is the cIOS Installer's job.
3. Click Start NUS Download!.
4. Repeat the step 2 & 3 for IOS56 v5661, IOS57 v5918 and IOS58 v6175.
5. Once you have downloaded all four IOS, there will be a folder named titles in the same folder as the NUS Downloader.
   • Open the folder and navigate through them until you locate the four WAD files you downloaded. Place each WAD file on the root of your SD card or USB drive.
   • This must be the same device containing the d2x cIOS Installer.

The WAD files should be on your SD card like this: {: .notice--info}
