Hi,

I have a wiiu console with hynix nand. One day it stopped turning on. I decided to use redNAND. I installed redNAND and ISFShax following the instructions. Now when I go into "Patch (sd) and boot IOS redNAND" it gets stuck on the following screen. I share the logs, what could I have done wrong?

Thank you..

I am not sure I can provide help with this. I am not familiar with a redNAND. My work with Wii U consoles with failing eMMC has been strictly using NAND-AID to replace the eMMC as a permanent repair to the console.

I remember reading about redNAND years ago and I thought this was a temporary fix to the problem. Do you have a link to a guide you used for this so I can take a look at it to get a better understanding of what redNAND is?

Based on the information you have provided it would appear that redNAND has some things in common with a NAND-AID installation.


Edit: is this the guide you used?

Thank you for your concern. Yes, this is the manual I read. Actually theoretically redNAND and NAND-AID are the same. I think it's a hardware problem, but I don't know where to start. Since I don't have a nand backup, I created the MLC area with MLCRestoreDownloader. Maybe I'm wrong here. I'd like to at least see a Wii logo.

Were you ever able to boot into the Wii U Menu after installing redNAND? If so how long did it work before it stopped working? It looks like your loading minute menu and its stopping there.

I took a look at the redNAND and it looks like redNAND redirects the Wii U to a partition on the SD Card that goes in the front of the console. If its not loading the Wii U Menu then its possible the SD Card has the problem. Have you checked the SD Card in a computer? Since redNAND uses FAT32/NTFS partitions can you view it in a computer to see if there is a NTFS partition still? Based on this guide the NTFS is only initially on the card and once you rebuild the MLC it shouldn't be there. 

When I look at the sd card, the ntfs partition is deleted. The partition that Windows does not support comes back. Wii menu won't load. I inserted 2 different sd cards, one 64 and one 128 gb. But same brand. Kioxia


There is a mod called de_Fuse. I wonder if I can see errors if I do this mode

Well if the NTFS partition is missing that indicates that at the bear minimum the Wii U formatted the partition to be used for the MLC. According the wafel_setup_mlc.log you provided there was no issue rebuilding the MLC on that memory card.

A couple things to double check:
1. Did you download the correct MLC titles for your region?
2. Did you double check to make sure you followed the steps in the guide?
3. Did you make sure you have all the latest versions of the tools? 

The guide states as step 7 to select "Patch (sd) and Boot redNAND" and you stated in your first post that you select "Patch (sd) and boot IOS redNAND" and nothing happens. This stands out as a key difference, are you using an older version of minute? 

Yeah defuse could certainly help. It requires advance soldering skills and a Raspberry Pi Pico to do though. 

Yes, your observation is correct, there seems to be no problem with the MLC.

1- I downloaded EUR with the help of MLCRestorerDownloade if the barcode underneath is correct.
2- I repeated the same process 4 times.
3- Yes, I downloaded the latest version from the github site.

I think the manual is old because the option I have is the only one that comes up. I think defuse is the only option I have left.

Even if the NAND is broken, it would still work with redNAND. Is that true?

That is correct, once a redNAND is setup all data is routed to the SD Card and away from the eMMC, so it wouldn't matter if the eMMC continued to degrade or failed at that point.

Are you positive the console is EUR? Did you use the recovery menu to pull the system information?

On a side note did you grab the SLC files and include them with the 52 titles so that during the rebuild process it updates and installs the latest firmware? Might be worth a try, I had a couple NAND-AID that had older firmware and I ran into some weird issues rebuilding the MLC. However those problems were solved once I included the SLC files to update the firmware. It would be worth a try before concluding that you have to use defuse. 

It says EUR in the console. I put both mlc and slc files in the installation folder, still no results, I finally tried the de_fuse method, I got the following log file, what do you think?

Amazing soldering job!! It would appear that defuse is working. No error codes.

To me it doesn't appear to be a console hardware problem, it would seem that the issue is software.

That being said I have limited knowledge/experience with defuse, so you would be better reaching out to SDIO and asking him to look at this log file.

I think the log is indicating the OS is crashing due to corruption. I would contact SDIO. He has been here before but I don't think he has been back, so you should probably make a post at gbatemp. 


Edit: I just remembered this and I apologize. We may have jumped the gun on defuse. I recall that defuse isn't necessary if ISFShax is installed and loads. I don't know if this information is still correct, yet another question that could probably be answered by SDIO 

Thanks, I love this kind of work

I'm so glad I installed defuse. I get a detailed log. ISFShax does not produce enough logs for me.

I hope there are no hardware issues. I have contacted SDIO and we'll see how to solve this. I will keep you posted. Thanks for your efforts.

Yeah please post back on the results so that if other people out there run into the same problem they have your thread to look at. I am also interested in knowing where the problem lies. I plan on grabbing a console and working through the redNAND now because, while its similar to a NAND-AID there are differences and I want to know if that guide you used it correct/updated.
