You will also need a RP2040 pico ZERO, some wires and a sd card up to 2gb, non-SDHC.

The amazing De_Fuse is created by shinyquagsire23 and it is open source:
https://github.com/shinyquagsire23/wii_u_modchip

It can dump OTP, dump and write seeprom and SLC. And more.
It is an esential tool for fixing bricked or full bricked consoles.

I can't offer any support regarding the software side.

QSB Installation:
1. Solder the connector to the QSB. Align the QSB with TP48-TP54 on the console motherboard. Scrape the solder mask where whe GND pad is. Solder the test points and GND pad. It is a good idea to check for shorts.
2. Solder wires from the QSB to TP101 and TP176. See the pictures for more details. They are routed in S shape so they won't get squashed.
3. Solder wires from the QSB to TP144 and TP122. There's no need to solder to TP164, because the gnd is already connected.
4. Connect the flex cable.
That would be all on the console side. If you want to keep the cable inside the console even after it has been fixed, you can route it to the top part. But you'll have to trim the bottom and top metal plates. Also the console motherboard. And at last the top right leg that hold the drive. I've included a pic to see what I mean.

PICO PCB:
1. Program the pico as per the github instructions. Prepare the sd card.
2. Solder the connector to the adapter.
3. On the back of the ZERO there are 4 pads that needs to be bridged (marked in red in the picture) and connect them to the pad on the back of the adapter.
4. SOlder the rest of the ZERO pads to the adapter.

If everything went ok, now when you power on the console, the led will turn purple and you will see a menu on HDMI.
Back up everything!!
