If you accidentally updated to 5.5.1, it appears that Yellows8's .mp4 exploit has NOT been patched (confirmed by Crediar).
Hykem say's 5.5.1 is OK (But update at your own risk !)
Just what is this thing, exactly?!
Hykem has developed an exploit that can be launched through the Wii-U web browser that can take full control of the system's iosu. From there, we can gain control of the kernel as well and have unrestricted access to the entire system!
What do I need?
- A WiiU on any firmware up to 5.5 (Any unit in any store will have this)
- An SD Card
- A WiFi connection for the WiiU to connect to
- *A compatible External Hard Drive (*Optional)
Phase 1: Setting up TubeHax DNS (Thanks Smea!)
Phase 2: Loading the Exploit (Coming Soon!)
So, should I update to 5.5 ?
TL;DR -- No, don't update. Stay where you are.
I SET UP TUBEHAX AND GOT THIS SYMBOL! DOES THIS MEAN A NEW FIRMWARE IS OUT?! OMG EVERYONE PANIC!!!
Calm down, it just means that the WiiU tried it's periodic check for an update file and failed because you have TubeHax DNS set up PROPERLY.
Hykem isn't currently accepting donations, but he wishes for you to donate to the developers that follow up with this exploit and their efforts!

Blocking future updates is critical to retaining exploits on your system. The WiiU automatically downloads and applies updates as it receives them, even in standby mode! You will still be able to play your games online with this, as long as the GAMES THEMSELVES are updated.
Step 1: Power on your system and go to Settings > Internet > Connect to the Internet.
Step 2a: If you don't have a connection already set up, do it now but when it asks if you want DNS to be Automatic or Manual, choose Manual and follow the rest of the steps.
Step 2b: If you have an existing WiFi connection, press X or tap the button in the top right corner to view Existing Connections
Step 3: Choose your connection from the list. I recommend only having 1 at a time so that if you are roaming with your WiiU or have more than one access point it doesn't switch connections and download an update on you.
Step 4: Change Settings > Press the Scroll Arrow on the Right > DNS > Don't Auto Obtain
Step 5: Tap the Primary DNS and set it to 107.211.140.065 -- You can leave the Secondary DNS as 000.000.000.000 (Some people don't know anything about networking and think this could leave their system vulnerable to updates. If you're paranoid, just set the Seconday DNS to 107.211.140.065 as well).
Step 6: Confirm > Save > Save > Quit

Step 1: Download the starter pack from HERE and copy it to your SD card, then insert it into the WiiU. (Coming Soon)
So, should I update to 5.5 ?
That's a complicated answer. There have been no -major- library changes from 5.3.2 to 5.5 (except the in-game manual app) so the chances of a game or homebrew not working on your version are slim to none. There is a small possibility of the 5.5 webkit exploit used for this being very unstable, and -possibly- even not working at all, but Hykem says he will support 5.4/5.5. Those on lower firmware still retain the extra chance for a more robust or stable hack, AND, once iosu is fully exploited, custom firmware can be installed on the Wii-U and emuNAND can be used, so the system version won't even be an issue anymore.
"But won't emuNAND be blocked like the N3DS?" you say. The Wii-U doesn't have the extra hardware that the N3DS has that blocks getting the keys to use for emuNAND. You can select and install components individually, or someone may make a "CFW Pack" to update your emuNAND with, which (may) contains pre-patched tickets/content to keep your emuNAND pre-modded. It's possible a newer iosu may come out that can't be decrypted, but... *shrug*

Initially? Nothing at all, unless Hykem releases a tool or app with the launch of the exploit (which he may or may not have hinted at). Eventually, this could lead to many, many things. Including:
- Countless homebrew games/apps/emulators
- USB Loader
- A title installer (Like Devmenu/BBM/FBI for 3DS)
- EmuNAND
- Real-Time Cheats
- Custom SysNAND firmware
- Custom game content (Mario Kart Tracks, Smash Bros. Fighters, etc.)
- NDS ROM Injection (!)
