USB Descriptor Parsing Is Hard (UDPIH)
An exploit for the Wii U's USB Host Stack. Pronounced like "mud pie" without the M.The write-up can be found here!
What does this mean?
Since the USB Stack is running before anything on the PPC side of the Wii U is booted, this allows unbricking things like CBHC bricks without any soldering!Supported devices:
- Raspberry Pi Pico
- Raspberry Pi Zero (W) / A / A+ / Zero 2 W / 4 / 5
- Steam Deck
- Nintendo Switch capable of running udpih_nxpayload
Instructions
Device Setup
Follow the setup guide for the device you want to use below:Booting the recovery_menu
Important notes for this to work:
- Make sure no other USB devices are attached to the console.
- Only use USB ports on the front of the console, the back ports will not work.
- If your console has standby mode enabled, pull the power plug and turn it on from a full coldboot state.
- Copy the latest release of the recovery_menu to the root of your FAT32 formatted SD Card.
- Insert the SD Card into the console and power it on.
- As soon as you see the "Wii U" logo on the TV or Gamepad plug in your prepared UDPIH device.
This timing is important. If you're already in the menu, the exploit won't work.
Depending on the device, you might have to plug it in sooner or later. This might take several attempts.
If you get no video output or a distorted screen, your timing was most likely wrong. - After a few seconds you should be in the recovery menu.
