Wii U failing during boot sequence

[MontyMole98]

So, I just got a parts/repair Wii U off eBay that I'm planning on, well, fixing and reselling. It came with a GamePad, which powers on fine, but it gives the "Unable to connect to the Wii U console" message when trying to boot into the Wii U Menu. If I try to turn the console on to pair it, however, the console doesn't output video through the AV port OR the HDMI port. I also have been trying to get it to boot into the UDPIH recovery menu (using a hacked switch) to dump the syslogs, but I only got the switch to even SAY that it succeeded once, even though the console's power light was still blue, not purple. The disk drive works fine, as far as I can tell, inserting games on boot will make it run (though it rejects them at any other time) and ejecting discs also works. That's one extra reason to say it didn't boot into the recovery menu when the switch thought it did - it would try to eject a disc if you pressed EJECT. Just for extra info, UDPIH gets frozen at stage 2, the last line that it prints is:

0x80 0x6 0x200 0x1 0x5390

Before giving error code 2. Any help is appreciated.

Then you probably need to defuse: https://gbatemp.net/threads/de_fuse-a-wii-u-modchip-in-development-by-shinyquagsire.630931/

From the thread you sent this seems to be in early development, how would I go about doing this?

 

[SDIO]

You need to solder a Raspberry pico, you can see the wiring here: https://github.com/jan-hofmeier/wii_u_modchip/blob/wiring-diagram/pico_defuse/README.md
Don't wire up 3V3 for now.

Get the latest release from here: https://github.com/shinyquagsire23/wii_u_modchip/releases and follow the instructions in the readme.

We should then see in the terminal what is happening and why it is crashing

Thank you, I'll hopefully get to that at some point next week.

Ok so I soldered it, the motherboard seems to be a different version, as there is no copper rim around it. How am I supposed to see the errors? Through the monitor.sh file? It won't run, just pulls up Git for a second and closes. Building it also fails. Sorry that I'm not able to figure this out now lol, any help would be appreciated.

That depends on your os on windows you need to use putty and on Linux minicom.

Modify the script to use Putty instead of Minicom? I am on Windows. So do I build and use monitor.sh? I'm a little confused.

 

[SDIO]

No, you don't need the script. The Pico should show up as a COM device, you can select in in putty. Select 115200 baud

Would you be fine sending me the build UF2 script for the Pi Pico? I can't seem to get it working.

 

[SDIO]

You need to press the button on the pico while connecting it to the PC, it will show up as a flash drive and you just copy the file there, it will disconnect and then it is ready

I get that, but I can't compile the UF2 file from the source code. I was asking for the compiled UF2 file if you've got it.

 

[SDIO]

It is in the release, you don't need to compile anything.
Just get the latest release from here: https://github.com/shinyquagsire23/wii_u_modchip/releases

Ohh I was looking at jan-hofmeier's repository which doesn't have any releases. I'll download it from ShinyQuagsire's now

 

[SDIO]

I just linkted to mine for the Picture, because shiny didn't merge it yet

Okay, I need to flash a 1 GB SD card now, so I'll have to get that too.

 

[SDIO]

Get a 2GB card, that will make installation easier as all the packages are sligltly above 1GB. 2GB is the maximum SDSC size.

Okay, will do.

Just got the card, but with the new release on ShinyQuagsire23's page should I follow the new SD method that doesn't require flashing (from what I can see) or just continue?

 

[SDIO]

Yes to have to flash the SD. And after flashing you have to format it with FAT32 and resize the partition
