The Wii U Hacking Guide
Each section is complete with requirements, download links, and a FAQ section to answer your questions before you can even think of them.
Disclaimer: I’m not responsible for anyone being updated past an exploitable firmware, bricking their console, crashing their PC, etc. Follow these instructions at your own risk. Your mileage may vary based on your operating system and computer specifications.

No, the “System Update” you see in the download log with a red X on it does NOT mean there is a new update out. That only means you are correctly blocking updates.
