Quote from: mpatl on Aug 28, 2025, 11:22 PMOh, that is all?  I had assummed that the mlc was 32gb in size.  I thought the mlc was the size of the system memory.

I'll track down a 2GB SD card.  I will post the crash log file shortly.

My apologies. I meant 32GB SD Card. You are absolutely correct when you said the MLC is 32GB in size. That was a typo and I didn't even notice it. Even so its incorrect because you need extra space to hold the necessary tools to dump the MLC so you would have to use something larger than 32GB. I use a 64GB SD Card.

00:00:11:269: FSA: ### MEDIA ERROR ###, dev:mlc01, err:-2228230, cmd:11, path:(null) is found in your log file, which indicates the eMMC is bad and the console needs a NAND-AID. 

So that's what I don't understand.  How do you use a 64gb sd card with defuse when the sd card has to be 1gb.

Is it the format redNAND option?

I would like to try and save the MLC if I can.  Mostly for the kids Miis.  They created them as small children and played them all the way to teens without modifying them.  They made ones for my wife and I as well.  They are nostalgic.

No its not the format redNAND Option. redNAND is a different recovery method. Its similar to the NAND-AID but redirects reading/writing to an SD Card in the front of the Wii U and uses that as a replacement eMMC. 

Well since you want to recover data than you would have to get ISFShax installed and use that to dump the MLC.

I have been very busy and responding to your posts late at night and again I have to apologize because it appears I misread your post about isfshax will not install from defuse.  It hangs at the GO GO GO. It sounds like you selected the option to rebuild the MLC, which means the data on there might be destroyed. Do you have the 52 Titles on the SD Card you are using with defuse?

You are not selecting the correct options if you are seeing this. ISFShax should look like this, check out my video.  https://youtu.be/XgN_S1PgbGU?t=588

You need to select Boot ios.img, which should start ISFShax installation then just follow the onscreen prompt to get it installed.

The option that I tried first was:
Patch Isfshax and boot IOS (slc). 
It hung at GO GO GO

I then tried the following after watching your video (I had watched three about defuse before contacting you again for help).
Boot ios.img

I got the error message
ancast: failed to open ios.img (2).
Failed to load 'ios.img'!

I was worried that perhaps I had wiped out info, but my console will still start the quick start menu on the gamepad and I can still see the Miis for selection



I do have the 52+5 titles from MLSRestorerDownloader with this console's otp.bin

It appears you are missing the ios.img file or its not located in the correct directory on the SD Card you setup.

Did you download the ISFShax zip from their website? If not download it.

Extract the contents and move everything inside the "sd" folder to the root of your SD Card. If you are asked if you want to merge/replace existing files select yes.

Then go back and try installing ISFShax again. I have attached a picture of what your SD Card should look like, kindly make sure the files in the picture are in the root directory of your SD Card. Also if there are extra files for Defuse, leave them on the SD. They will not show up in the picture below as I am only showing the files that are included with ISFShax. 

I did have the directory structure wrong.  Unfortunately that was not the problem.



Is redNAND an option to get a image of the MLC if isfshax won't install?  I noticed in a response in one of your guides that SDIO says there are 3 ways to image the MLC and number 2) was with redNAND.

I suppose I can give up on the MLC.  I believe all the eshop games were stored on the USB SSD drive that we had attached to the system which as far as I know is still healthy.

Based on your picture it doesn't look like an error at all. After the IOS GO GO GO the Wii U should output on the display the ISFShax Installer. You won't see this on the serial console.

Do you have your Wii U plugged into a monitor or tv? As a reminder minute only outputs over HDMI at 1080P. 

If you have no output lets try to blindly load ISFShax. So to do this you want to select the boot ios.img option and then once you see IOS GO GO GO in the serial console lets wait a few seconds and then push Eject 3 times followed by Power Button 1 time, then Eject 3 more times. If done successfully the console should turn off.

With ISFShax installed. The Wii U should start with the minute menu without defuse and the power LED on the console will be purple.

To answer your other questions. Yes the redNAND can be used to get an image of the MLC depending on the state of the console. I don't know the specific instructions to make this happen off the top of my head, so I recommend you ask SDIO how to do that.

As for the eshop games. All the consoles I repaired had no issue downloading games that were previously purchased on them, so getting those back isn't a problem. I don't think that has changed in the last couple of months.

Sweet.

I remember you clearly saying that isfshax only outputs on HDMI.  I had gotten so used to putty that I didn't even have the monitor on.

MLC is dumping now.
