vWii Modding Guide

---

This page will guide you through the process of modding your vWii.

We will now place the required Homebrew files on the SD Card.

?> Notice Your SD Card will need to be formatted as FAT32. If your SD Card is not formatted to FAT32, use GUIFormat with 32k (32768) Allocation unit size to format it. Do not label the SD Card as wiiu or it will cause issues with homebrew.

What You Need {docsify-ignore}

• The latest release of the vwii-compat-installer.
• The latest release of the Wii U NAND Dumper.
• The Patched IOS 80 Installer for vWii.
• The d2x cIOS Installer.
• The Homebrew Launcher.
• The latest release of the Homebrew Launcher Installer.

Instructions {docsify-ignore}

NAND Backup

In case anything goes wrong in the later process and your vWii ends up bricked, restoring a previously made NAND backup can fix it.

1. Launch the Homebrew Launcher.

   • Dump MLC: optional
   • Dump OTP: yes
   • Dump SEEPROM: optional
4. Press the A button to start the dumping process.
5. When the process completed, power off your Wii U, take your SD Card out of the Wii U and plug it into your PC.
6. To make sure you don't lose the files, copy the slccmpt.bin, otp.bin and if you chose to go with a full backup, seeprom.bin, slc.bin, and every mlc.bin.part file to your computer.
7. Delete the files from your SD Card to free up space.
8. Take the SD Card out of your computer and plug it into your Wii U console.

Patching IOS 80

!> If for any reason, the Wii U is turned off while patching IOS 80, your vWii will be bricked. This can be fixed by either extracting the IOS 80 from your previously made NAND backup and then replacing it over FTP or by reinstalling IOS 80.

1. Launch Patched IOS 80 Installer for vWii.
2. Read the warning screen and wait 30 seconds.
3. Press any buttons to install.
4. Wait until it says IOS80 Installation is complete!.
5. Press any buttons to exit.

!> Installing custom System Menu is a definite brick risk and you should always have an effective backup before installing one but when done right, won't brick the vWii.

!> Installing any IOS (including TED IOSes) or wads made for the original Wii on your vWii will brick it.

!> Installing Priiloader will brick your vWii.
