Hello!

This is a long story, but it’s probably best to get into everything that’s happened with my console. Would absolutely love some input! TDLR will be at the end.

Anyway, just at the beginning of the pandemic, I was really into Splatoon 2 and it made me want to play the original, so after many years of playing my Switch (I stopped playing my WiiU after it launched) I took it out of storage. It booted fine, however I kept encountering multiple error codes (the ones I recorded include 108-0035, 160-1710, 150-2031) and my console just kept freezing; although the more I’d shut it down and try again, the longer it’d go without freezing. At the time, I was thinking if I tried a system update, surely it’d fix the freezing, and I’m sure you could guess what happened.

At this point, I had called Nintendo customer support and they advised me to turn off my wifi and see if it would respond to it - it did not. Everything was frozen. I had no choice but to pull the plug and it was then on I would be trapped at the logo screen. They gave me the details to send in my console for repairs, but I did not have the money so I did not end up going through with it. About a year and a bit later, I tried again and I took it into a local EB games (yoo any aussies?!) to see what they could do before going to Nintendo. I got it back and they listed it as unrepairable; they listed the fault being system memory corruption caused by freezing mid-update, which was from motherboard failure (assuming from leaving it unpowered for so long).

Recent discussions of WiiU failure and unbricking has inspired me once more to get it fixed; I had seen Voultar’s video and, while I did not have those error codes, the core issue was ultimately the same - corrupted system memory. Worth a try, ya know. I don’t wanna throw my WiiU away. So I had bought a pico, which just arrived today, and I have been going through the steps. What happens though is once I insert the pico to the screen, my WiiU just instantly shuts down. I think saw a flash of the recovery boot screen before it’d do that, but otherwise I cannot progress. It still boots to the frozen WiiU screen if I don’t insert it, so the pico didn’t like kill it.

I’m really just thinking I screwed up in going to do a system update back then (honestly I really don’t know why I thought to do that), but I wanna rule out all options first.

Any thoughts from this?

TDLR; WiiU kept freezing after taking out of storage w/ codes 108-0035, 160-1710, 150-2031, froze mid system update, begun only booting to the logo screen; have been trying to go into recovery using UDIPH however inserting pico forces console to shut down.

Do you know which firmware you were on before the Update?
If the Wii u shuts down from udpih it usually means the SDcard isn't prepared correctly. Is it formatted FAT32 (not exFAT) and does it have the recovery_menu file in the root?

If you get the menu to work, the first thing you should do is dumping otp. After that you should dump the logs and send them to me with a PM for analysis.
Third thing would be to go to system information and note the manufacturer and CID of the MLC/eMMC.

What voultar showed won't help you, because it only applies to CBHC bricks.
If you go to the Coldboot menu it will show you in the top left the current coldboot title, which should already be the same as you would set it to. You can try it, it won't break anything,but I am certain it won't fix your problem.

No I don’t, sadly. I would want to take a guess as to what it would be - I did stop playing it about when the switch launched, then again I couldn’t know for certain.

I think you may have been right about the sd card. I did format it to FAT32 but I don’t think I did it properly originally, so I think I fixed that. My WiiU still went to shut down when I did it again - further attempts it didn’t shut down but still with the logo there. I could have just been missing the timing but I had realised the light was purple. I think it was doing that anyway though, I just didn’t notice it from the usual blue light. That should mean it’s being recognised, right?

I thought to try using the recovery_menu_dc_init file + renaming it and this actually made my screen change; although, it’s just a white screen and a bunch of blue/purple lines going through the middle. I guess that’s something though. I went to assume I was in recovery and tried to navigate the menu blindly for the logs - didn’t get anything from doing that though :mellow:

If you used my menu it has the options ordered differently. Try to dump otp with the original recovery

I didn’t realise you had your own repairs, but I looked and holy crap you’re INSANE!!! Thank you for your breakthroughs in the community - mad respect!!

I had been just following the steps provided by Gary for UDIPH and going from there, but with my lack of progress, I’m going to try and hardmod my WiiU - at least to a point where I can get some data to work from. Your methods and references I think could really help me. Only thing is I have no experience at all, so I’m going to start learning soldering while I try and get a better understanding of how all this works.

I’ll keep you updated on how everything goes! And thank you for all your help so far. I finally have a way forward for my console :D

It's still work in progress and the SLC dumper still has problems. it will be integrated in Garys menu once it is ready.
You should try to get OTP and SEEPROM first. without them we can't analyze a dump you did in hardware. Maybe try it blind in garys menu.

Here is a updated version of my dumper, which should give indication on the power led. After booting it just press power once. After half a minute or so the power LED should start flashing yellow.
