u/Altruistic-Walrus-90

I bought a year ago a wii u second hand but it did not have the gamepad, i tested when i got home and boot with no issues i could not play due to obvious reasons but yesterday i got a gamepad after wiring everything and turning on the console I got the Wii U logo flickering for a second and then just stuck in the logo.

I Tried following this guide https://www.youtube.com/watch?v=14n5r1rRB9s

But on the repo it shows steps for setting up with a steam deck since I don't have a pi pico but no luck.

From what I been reading it is fixable because it makes double sound of the disc reader

But im looking for some help and if anyones had some luck fixing their console.
