Wii U 5.5.5 fix 106-0103 or how to reinstall a clean OS.
Highly recommend making a physical Nand backup.
Cheapest option using SD card reader
Also I would recommend using SD card instead of nand. This method did not work for me, because I had suspicions that the download was coming from the boot1 or boot2 area. But after reading the nand configuration, I realized that the download is coming from the user area.
Instruction:
1. Enter the recovery menu using your Nintendo Switch or Raspberry Pi Pico.
In the recovery menu, we need an item install WUP .
Through it we will restore the file system.
2.Download Title Update
Example "000500101000400A"
NUSgrabber version dos.
Download the update from the Nintendo server.
NUSGrabber OS 5.5.5-Download OS.bat
Download the update from the Nintendo server in your region.
NUSGrabber EUR 5.5.5E - Download EUR.bat
NUSGrabber EUR 5.5.5J - Download JAP.bat
NUSGrabber EUR 5.5.5U - Download USA.bat
3.Install header update
3.1 Setting the installation folder on the SD card
3.2 Copy the contents of the sample "000500101000400A" to an empty installation folder.
3.3 Insert our card into WII U and install WUP through the recovery.
3.4 After installation turn off WII U and repeat 3.2 turn on and install TitleUpdate one by one.
4. Turn on Wii u Mode and go to Home.
If the memory in the settings is not displayed correctly, you need to do a complete removal through the settings and reconfigure the console.
