Discovered boot exploit for software-disabled Wii U consoles through recovery of Nintendo's damaged and discarded SD cards; team shares 'paid the fin' exploit on Github
In a groundbreaking discovery, a group of tinkerers has unearthed an exploit that can recover almost any Wii U console that has suffered from a software brick. The exploit, named "paid the beak," was discovered by analysing discarded SD cards from Nintendo's factory setup.
These SD cards, it turns out, contained a boot image called SDBoot1, which was used during the factory setup of Wii U consoles. After recovering 14 such SD cards from the factory's e-waste, a member of the group, Rairii, found a vulnerability in the SDBoot1 image, leading to the creation of the exploit.
The exploit's significance lies in the fact that SDBoot1 runs even on consoles with empty flash memory, making it a critical component for recovering bricked Wii U consoles. However, to use this exploit, one needs a rare Nintendo jig or a microcontroller like a Raspberry Pi Pico to trigger the UNSTBL_PWR flag on the console, allowing it to boot from an SD card.
The process involves flashing an SD card with the exploit and using a jig or microcontroller to boot the console from the card. If successful, the console should display specific signs, such as a blinking blue power LED, indicating that the exploit is working as intended.
It's important to note that Seeprom issues or actual hardware failure are the only cases where SDBoot1 cannot save devices. In such cases, another mod chip, called de_Fuse, can recover Seeprom failures but requires more advanced skills.
This discovery not only opens up new possibilities for Wii U hardware experimentation but also makes it more accessible without the need for disassembly and specialized soldering skills. The "paid the beak" exploit, now available on GitHub, is a valuable tool for Wii U owners who have encountered software issues and are looking for a solution.

Rairii, the group member who discovered the vulnerability, employed the rare Nintendo jig or Raspberry Pi Pico to create the "paid the beak" exploit, functioning on smartphones like smartphones, along with other gadgets, to recover bricked Wii U consoles. The exploit's success is indicated by a blinking blue power LED, making it a valuable tool for those experiencing software issues on their Wii U gaming device.
