Wow, ninja'd. Just when I was putting the finishing touches
I'm gonna post this anyway just cause I typed so much. No offense
@gutoblauth
Make sure your Wii U is on the latest firmware, as of this writing, version 5.5.1. All the cool kids use it now.
Plus, as far as I'm aware, there is no benefit to being on older firmwares, someone correct me if I'm wrong.
Don't blame me if 5.5.X magically comes out and your updated to it.
Read all threads and thank the makers.
Block future updates using this

There are two side-effects when blocking updates:
1) You also block your ability to use the Eshop.
2) The system will ALWAYS say it failed to download an update, even when there is no update, so don't panic.
You CAN play online while blocking updates.
There are a few ways to launch the Homebrew Launcher but first you need to set up your SD card.
Grab the Homebrew Launcher from here.
https://github.com/dimok789/homebrew_launcher/releases
All your homebrew apps including the Homebrew Launcher will go in
SD:/wiiu/apps/
Grab more apps from the Temp or here
http://www.wiiubru.com/appstore/#/
If your looking to play Smash Wii U mods grab this app especially.
http://www.wiiubru.com/appstore/#/app/SDcafiine
With all that set up we can move on to launch methods.
Here are three that I know about.
1) Easiest
Go to loadiine.ovh/ on your Wii U
Follow the sites instructions.
2) Use your Android phone or tablet
There are two apps for hosting exploits. Follow their instructions.

3) Use Haxchi. Requires purchasing a specific DS game.

If you followed all of the above you should be able to launch Homebrew. Congrats. Now go figure everything else out, cause I haven't.

You probably already did, but read gutoblath's post. They explain some stuff I didn't
