UDPIH: USB Host Stack exploit + Recovery Menu

Robotron2000 · Sep 30, 2022

My system was working fine and was modded but you needed to activate the mod after boot otherwise the system was just fine. I went to use it the other day and now it just freezes at the WiiU splash screen so I tried this to dump some logs.
The only error I can see is Miiverse related and I am unsure how to fix this.

That does not seem like a complete logs folder. Was that the only file in there? Can you try copying them again?

Sorry about that, I selected a file instead of the folder.

I tinkered a bit with wupserver/client, edited the system.xml file, replaced the safe.rpx with the one from "PayloadfromRPX"... and managed to manually use Tiramisu again despite WUP installing the original Health and Safety app before this.

With this, I booted into vWii by pressing "+" at launch and tested my disc drive... it is working flawlessly, like, I played using my old Wii Sports disc and it works wonders, not a single issue... so... is it really my disc drive what is failing? I know the Cafe OS logs seem to indicate that, but since it works perfectly fine in vWii it doesn't make much sense to me.
Homebrew Launcher isn't working though, it shows a black screen when trying to launch it.
@GaryOderNichts

Okay I just realized something...
Since the recovery_menu always powers off the disc drive, ODM will always go into a fatal state on the recovery menu.
So all your logs regarding the disc drive are probably from the recovery menu itself.
This was my bad, will take a look at your logs again.

Your system fails to load the default fonts on startup due to data corruption.

Code:

00:00:08:065: FSA: ### DATA CORRUPTION ERROR ###, dev:mlc01, err:-1245211, cmd:11, path:(null)

There is also this log from a while back when launching Amiibo Settings:

Code:

This unfortunately is another broken HYNIX MLC :/

Thanks for your analyses of this. From what I have read this appears to be happening more and more.
Guess I'll box it up and maybe someday there will be a solution.

Ah, that makes sense! I watched the video you posted in the first post, and I saw that when you pushed the eject button in the recovery menu your disc drive still tried to eject discs. My disc drive doesn't do anything when I push the eject button while in the recovery menu, now I understand.

By the way, I have deleted the contents of the logs folder and now I have a few new fresh logs generated, considering the ODM thing, I did what you said about the recovery menu and yes, the ODM_STATE_FATAL error is not present anymore once I dumped them without entering the recovery menu before. I will just leave the logs here, maybe it will be easier to look at them now that there are fewer and only from the console in a non-booteable state.
Thanks a lot!

Are you familiar with https://lazr1026.github.io/tudpih/#/. It apparently suppose to install Tiramisu with UDPIH for those who can't use the browser.

Can a hardmod restore the HYNIX MLC?
This is what I have backed up.

While is true that restoring a NAND backup can fix your problem if you have data corruption, your NAND has reached the end of its lifespan as far as I can see. Gary pointed to a line in the log that says

Code:

00:00:30:623: FSA: ### MEDIA ERROR ###, dev:mlc01, err:-2228230, cmd:11, path:(null)

If I understand correctly, "MEDIA ERROR" means that your chip is damaged and can't retain the integrity of data anymore, so I don't think restoring the NAND will help.

This seems further implied when random data like amiibo settings or the fonts of Cafe OS became corrupted with no apparent reason.

So the only real solution is a new base unit or chip replacement which is not happening. It doesn't even make sense to buy a replacement unit because who knows how long that will last.

Thanks for the feedback.

i have a very big problem some time ago i went in the mlc folder and deleted the font files i dont have any autoboot cfw i only have mocha i dont know if wupserver can fix the wiiu i will attach the logs (i dont have any nand backup)

I suggested before to have a homebrew loader throught UDPIH. If it work, we could probably use RedNAND to have a MLC-bricked Wii U to sort of work again.

But that's not a real solution i would say. The console boots...somehow...but what when your rednand "dies"? Creating a new one is not possible when your real chip is already dead

Ah yeah, the disc drive only powers down since version 0.3.

Went through your new logs and your console always crashes in HBM.

Code:

Did you do any modification to the console which might cause this?

You can grab a WUP for the fonts using JNUSTool (Title ID: 0005001B10042400), place the files into the install folder, and use the "Install WUP" option to reinstall them.

If we ever have a method to properly coldboot redNAND, that would be an option for MLC-bricked Wii Us.

Thanks for checking them! Hm... Just to be sure do you mean software-wise right? Because I did not touch anything hardware related.

I was using WiiUFTPServer (not FTPiiU) before all of this because I wanted to change the Wii U Chat icon with a Custom Mocha one (Used PotatoHax to inject Haxchi there).
Long story short, I ended up corrupting Wii U chat because I didn't do things well with the .tga file, so it showed a "???" mark in the Wii U Chat slot in the menu.
Since it was corrupted I ended up deleting Wii U Chat using WiiUFTPServer and I also saw that there was the Nintendo TVii folder, so I removed that as well since it wasn't being used in the menu anyway.
I was confident about this since I had deleted a lot of stuff in the past, even Parental Controls... and my Wii U didn't brick, the icons just dissapeared and that's all. I ended up restoring those apps later on because my console would crash when creating new users.
But, aside of that, I didn't do anything more, that's why I'm a bit shocked that after removing those folder my console stopped working, because I have done the same thing in the past and nothing happened.

EDIT: The only difference this time was that instead of using FTPiiU I was using WiiUFTPServer. And used FIleZilla instead of WinSCP, since I couldn't get WinSCP to work with WiiUFTPServer, but that's all.

EDIT2: https://github.com/Laf111/WiiUFtpServer/issues/26 It seems that deleting files using WiiUFTPServer with FileZilla corrupts the file system.... uh.... not sure if that issue there is accurate, but maybe is related to my problem? After all, I have deleted files using FileZilla and WiiUFTPServer, the only diffence being that I did it on my MLC and not SDCard.
This did not happen when I used FTPiiU with WinSCP.

EDIT3: I Found this error in my logs:

Code:

00:00:22:283: FSA: *WARNING!* Data buffer for read request from pid 0xc is not aligned on a 64-byte boundary.
FSA: It should be 64-byte aligned for file system performance.00:00:22:303: FSA: *WARNING!* Data buffer for read request from pid 0xc is not aligned on a 64-byte boundary.

Seems file-system related... I'm starting to think that my problem could be related to the issue above.

Another thing is that I haven't done any HBM modification whatsoever, in fact, I don't have a clue what HBM is, but that's all I did to my console, I had not messed around with fonts or other stuff.

gary you are amazing - perfect timing for me as I redid coldboot after the 5.5.6 update and the file was corrupted on my sd card and it bricked - super quick fix much appreciated

Post automatically merged: Oct 6, 2022

Also a buddy has a Wii u console that keeps trying to reformat upon startup but failing, could this work for that also?

Reformat? An hdd or what?

Sorry he just wrote “Console turns on but starts a memory format that never completes”. Apologize should have got more details before asking
