cIOS

{% include toc title="Tabla de contenido" %}

While cIOS has largely been supplanted by AHBPROT, which gives complete hardware access, it still has useful applications. You can now use homebrew such as USB Loader GX and WiiFlow. You can skip this process if you want, but generally it extends your Wii with little to no downsides.

If you have a Wii mini, install this cIOS instead. Attempting to install any other cIOS on a Wii mini won't 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

If your Wii has an Internet connection, you may skip this section.
However, If you encounter any errors like net_init failed, net_gethostbyname failed:, or any other issues during the downloading stage 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. Power off your console.
2. Insert your SD card or USB drive into your computer.
3. Download, extract, and run NUS Downloader.
4. Copy all files from the NUS Downloader .zip to a folder on your computer.
5. Run NUS Downloader.exe.
6. Navigate to Database > IOS > IOS38, then select v4123.
   • Ensure that "Pack WAD" is checked and "Patch IOS" is unchecked.
   • Don't check "Patch IOS". That is the cIOS Installer's job.
7. Click Start NUS Download!.
8. Repeat the previous step for IOS56 v5661 and IOS38 v4123.
9. Once you have downloaded all three IOS, there will be a folder named titles in the same folder as the NUS Downloader.
10. Open the folder and navigate through them until you locate the three WAD files you downloaded.
11. Place each of WAD files 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}
