Installer la MAJ d'un jeu et une fausse derniere version sans les téléchargers de manière officiel.

Hey everyone here is a TO DO List for Wii U User

FAQ:

What can it do?
This hack allows you to install any valid NUS content from an SD card, including game updates.
The easiest way to obtain those is directly from Nintendo's NUS (see tools).

What are the risks?
This hack installs content to your NAND using the official Nintendo update functions.
This installation is PERMANENT and can currently not be reverted, game updates can be uninstalled.
The risk is the same as installing an update normally.

How does firmware spoofing work?
The Wii U uses a binary file which has the current version and region of the system saved to it called version.bin.
In this case we install the content from the latest version title and so the system has the version.bin from the latest version.

What does work after installing the latest version title?
With just installing the latest version title you can use all online functions.

Trying to do game updates from the Wii U Menu does still prompt you to update your system first but you can workaround by installing updates by hand.
After that you can normally start the game.

The eShop implores additional checks and wants you to update your system first, there is currently no workaround (We are still looking into a solution).

To prevent people from bricking their systems the installer has a whitelist of titles you can install.
You can install any game update and the version title, as these are completly safe to install.

Tools:
NUSGrabber:
This is a special version that directly renames the files to work with the installer.
[Download]

This tool requires the: Visual C++ Redistributable for Visual Studio 2015

Requirements:
-SD card, large enough to hold whatever you want to install.
-Wii U at 5.3.2 JAP/USA/EUR (Other versions are untested and might work)
-Enough space on the Wii U NAND, this will not install to USB.
-Something to install you can either use the version title packs or download game updates from NUS.

Here is a list of title IDs for games: Title Database
To obtain an update of a title replace 00050000 with 0005000E for example for Mario Kart 8 USA: "NUSGrabber.exe 0005000E1010EC00"
If you don't supply a version NUSGrabber will download the latest version.

Installation:

PC
-Download the title you want to install using the NUSGrabber tool and put the files (*.app, *.h3, title.cert, title.tmd and title.tik)
into a folder called install on your SD card (sd:/install)
You can only install one title at a time.

Wii U
-Put the SD card into your Wii U at any time before loading the exploit.
-Start the browser and go to this site [LINK], you should be returned to home menu,
-Start the browser AGAIN using the same URL, you will be returned to the home menu again.
-Exit to the Wii U menu, the installation is done in the background and usually takes about 5-10 minutes depending on the size of your title and speed of your SD card.
The version title install is instant.
-Reboot your system and check if it installed correctly in the data management, or system settings when you installed the version title.

If you get any kind of error hold power for 4 seconds and try again.
