2: Preparing & Running the Kernel Exploit - FlimFlam69/WiiUTutorial GitHub Wiki

This is where the fun begins! In this section, we'll be setting up the SD card so we can run the kernel exploit. There are a couple way to go about doing this and we'll explore some of those options.

If you have already gone through the Starter Pack set-up, you're already set up to run the kernel exploit. You can skip the 'Kernel Exploit Prep Work: Setting up Your SD Card' section.

Kernel Exploit Prep Work: Setting up Your SD Card

Step 1) Format your SD card to FAT32. If the linked method doesn't work for your OS (or if FAT32 isn't listed as an option), you need additional software. /u/LightPrism suggests fat32format. If you're using a MAC, you might need something like this.

Note: Windows 10 has a... funny way of formatting devices. If you're on Windows 10, just use fat32format to prevent future problems.
Note 2: If you can, use 64kb clusters. If that ends up not working, try 32kb clusters. I've gotten them both working on Wii U, but people have been saying they have better luck with one or the other.
Note 3: If you have to name your SD card, do not name it "wiiu". It's been reported that this will not work for whatever reason. (Thanks /u/unfortunate_timing, I should've added this tidbit a while ago!)

Step 2) Download Homebrew Launcher 1.4.

Step 3) Extract the contents of the .zip file to the root of your SD Card (It should only be the one 'wiiu' folder).

Running the Kernel Exploit: The Easy Way

Step 1) Put the SD card into the SD Card slot in your Wii U

Step 2) Turn on your Wii U, and go to the Web Browser.

Step 3) Go into your internet settings and Reset your Data. (If this isn't your first time running the exploit, you can probably get a way with just Deleting Cookies.)

Step 4) Back out of internet settings and type this into the address bar: http://loadiine.ovh/

Optional: Bookmark this address so you don't have to type this in every time you want to run this particular exploit in the future.

Step 5) Ensure that the displayed drop down box is displaying "Homebrew Launcher..." and press the Submit button.

Step 6) Presto! It should have worked, and you should be seeing the Homebrew Launcher menu within seconds. If it freezes on a white screen, then just do a hard reset and go back to Step 2.

Note: A hard reset means that you need to hold down the Wii U's power button until it turns off. The Wii U tablet will say it lost it's connection to the Wii U, but all you have to do at this point is hold down the power button on the tablet until it turns off.

At this point, you can stop and move on. However, if you wanted to look into your other options for loading the exploit, keep reading!

Running the Kernel Exploit: The Self-Hosting Way

This guide is written for Windows Operating Systems.

With this method, you will be self-hosting the Wii U exploit, rather than going to loadiine.ovh every time you want to get into Homebrew Launcher. This is literally using the same payload http:/loadiine.ovh uses to exploit your console online, so you should be getting close to a 100% success rate with this.

I have made a package for everyone to download that includes instructions on how to do everything. I've made it as simple and noob friendly as possible, though the guide assumes you have followed the "Kernel Exploit Prep Work: Setting up Your SD Card" guide from above. You can download the package below.

Note: This is a modified version of Kafluke's all-in-one package from GBATemp. Special thanks to Cybernatus (From GBATemp and loadiine.ovh) for making this payload public.

Running the Kernel Exploit: Self-Hosting and Taking Your Wii U Offline

This guide is written for Windows Operating Systems.

With this method, your Wii U will be completely offline and still be able to access the exploit. This is literally using the same payload loadiine.ovh uses to exploit your console online, so you should be getting close to a 100% success rate with this. It will be impossible for Nintendo to update your console, but you will obviously lose the ability to browse the eShop and play games online.

Note: This is a modified version of Kafluke's all-in-one package from GBATemp with incorporating Seita's idea to use Connectify in order to take your Wii U offline completely. Special thanks to Cybernatus (From GBATemp and loadiine.ovh) for making this payload public.
