What is this for?

If you are encountering Error Code 160-0103 "There is a Problem with the system memory" or your Wii U is freezing at bootup or during Factory Reset it is likely that the eMMC Chip is failing.
This tutorial goes into fixing this Error 160-0103, by using the SD card in the front slot as replacement for the failing eMMC.
In this tutorial we will rebuild the MLC, which means it is empty, whithout your data. In the end I show how to salvage savegames from the failing eMMC.

Please note there are other possible causes for the 160-0103 error (like a CBHC brick). Also there are other possible solutions to this problem. To see if this Tutorial is right for you, check out the Ultimate Wii U Troubleshooting Guide

What this will do

We will first install ISFShax, which is an early exploit that runs before the operating system loads. This allows us to patch the OS to redirects the reads and writes, that normally go to the eMMC, to a partition on the SD card. So you will need to have the SD card in the Wii U to use it, as that is now it's new internal memory.
Also you need to keep the standby servcies (and with that the Quickstart menu) disabled as they don't work with ISFShax. (Your Wii U will hang once you turn it off till you remove power if standby services are enabled).
In this tutorial we are only redirecting the MLC. If you plan to try some dangerous things in the future, you can still mess up your system SLC and SLCCMPT. If you want to use this for such experiments consider using full redNAND, where all 3 devices get redirected.

Update

28.01.2024 - Wii VC games (from he eShop or VC Injects) now works from the redNAND internal memory. Keep in mind that Wii VC is more picky about the SD card. So far Sandisk cards worked for me, but Samsung cards didn't. If the card is incompatible, it will hang on a black screen after the silver Wii logo.

Choosing an SD card

I highly recommend to use an SD card, which is designed to sustain lots of writes, like Sandisk Max Endurance or at least High Endurance or Samsung Endurance. The absolute minimum size is 8GB using, 1,5GB for the FAT32 partition and the rest for the MLC partition, but it is recommend for the the card should have at least 16GB, so you can have at least 8GB for the MLC partition. The Maximum size of SD you can use is 2TB.

Spoiler: Tipps for sizeing the SD card

Since the Wii U Discs suffering from Disc rot and also for convenience, you probably want to dump all your Game Discs and install the Games from these Dumps You find detailed instructions on how to do that here: https://wiiu.hacks.guide/#/dump-games (do it after you completed this guide)
Later in that guidel you will create a second partition, which replaces the Internal Memory. You won't be able to resize that partition, without rebuilding again, so you better size everythng properly the first time.
The first partition is where all the Homebrew goes to and also where the dumps of the Wii U games go to. So this partition needs to have at least enough space to store your largest Wii U game with some extra space. If you want to use a USB Loader with vWii, you can also store the (OG) Wii games on the FAT32 partition.
The second partition (the MLC partition, which you format initally with NTFS) is where you install all your Wii U games (eShop and dumped Disc games, updates, DLC, saves...) to, including the VC Injectes. Also 5GB are used up by the Wii U system.
Make sure the the SD card can fi both these partitions.

Installing ISFShax

For installing ISFShax follow this tutorial: https://gbatemp.net/threads/how-to-set-up-isfshax.642258 but skip the "Autoboot" part for now.

Optional: Backing up savegames

If your Wii U can still run Tiramisu or Aroma: https://wiiu.hacks.guide/#/ you can use SaveMii to back up your save games.
If it can't you then you probably already used UDPIH to install ISFShax. Launch the recovery again using UDPIH and then use the Dump SLC + MLC option. Your SD card needs to have at least 64GB for that (for a 32GB console). You then need to merge mlc.bin.part files in the right order and can then extract the savegames using wfs-extract.
TODO: add more details

Spoiler: transfering the NNID without password

If you lost the password to your NNID and can't recover it because the email doesn't exist anymore, you can transfer it. This is only a last resort option. If you still have the email address, it would be better to use the "Forgot Password" option now, as you won't have it on the new system.
There is also the option to use a password reset option on the PC. For that you need to create a Nintendo Account and then link the NNID to it. When linking it will ask for the password and give a reset option using the email.

Keep in mind this transfer only works on the same console and only if you don't do a Factory Reset.
To transfer the NNID It's enough to copy the account.dat file over.
You can use ftpiiu everywhere to save it to the PC for now. Just copy the whole /storage_mlc/usr/save/system/act/ folder to the PC. In that folder you find one subfolder for each user and in that subfolder you find an account.dat (it's a plain text file, you can open it with notepad). The folders are numbered in the order the users were created.

On the new rebuild mlc the numbering will start again with 80000001. If the user with the NNID had a larger number just create new users on the new system until you reach that number. Then you can copy the account.dat back and reboot.
After that you should be able to access the eShop and download the games again.

Partitioning the SD card

On Windows you need to use a third party tool like Minitool Partition Wizard or easeus, on Linux you can use gparted.
You need to have two primary partitions on the card:

1. FAT32 - (in gparted set lba flag). This is what the PC will see and all your homebrew goes
2. NTFS - This partition will be the MLC replacement, it should have at least 8GB. (don't assign a drive letter)

Shrink the existing FAT32 partition to make room and then create the NTFS partition after it. It's recommended to align the Partitions on 64MiB boundaries and use a multiple of 64MiB for the size. The MLC (NTFS) partition should be at least 8GB but other than that you can choose whatever sizes you like.

Configuring redNAND

Create a file minute/rednand.ini on the sdcard with the following content:

[partitions]
slccmpt=false
slc=false
mlc=true

[scfm]
disable=true
allow_sys=false

Rebuilding the MLC

1. Download all the mlc system titles for your region from NUS. This can be done conveniently with MLCRestorerDownloader by @Xpl0itU. To use the MLCRestoreDownloader, you need to extract it and then copy the otp.bin from the SD card to it's directory. Then start the Downloader and select mlc and then your consoles region.
   You will get the output/MLC/{region} directory, which contains a directory for each title. In total there should be 52 titles totaling ~1.1GiB.
   If your console has an older firmware it might also be necessary to get the latest SLC titles.
   
   
2. On the root of your SD card create a folder wafel_install. Then copy all 52 titles to the wafel_install folder, so it now contains the 52 subfolders, one for each title. If you want to reinstall / update SLC titles, you would also put them there.
   
   
3. Put the wafel_setup_mlc.ipx on the SD card in /wiiu/ios_plugins.
   
   
4. Select Patch (sd) and Boot ios redNAND in minute to start the setup of your fresh MLC.
   During the setup you won't see anything on the screen. You have to go by the power led.
   The power LED will flash blue, while it is installing the titles.
   if something goes wrong the LED will turn orange, but it will continue as long as it is blinking.
   The LED will become static once it finished. You can now power off the console.
   If the led is blinking red, something fatal happend. Ask for help.
   During the setup a short log gets written to the SD: wafel_setup_mlc.log.
   In the end it will enable the inital setup on the next boot.
   
   
5. Remove the wafel_setup_mlc.ipx from /wiiu/ios_plugins on the SD.
   
   
6. Select Patch (sd) and Boot ios redNAND again. If everything worked, the initial setup should launch.
   (no longer required with latest minute)
   
   
7. Follow through with the initial setup. After the "settings" part of the setup, it will drop you back into minute, just select Patch (sd) and Boot redNAND again.

Setting up autoboot

To automatically boot into redNAND create the file sd:/minute/minute.ini with the following content:

[boot]
autoboot=2
autoboot_timeout=1

Installing minute to SLC

If you haven't already installed minute (fw.img) to the SLC, you should do that now so In case the SD get's lost the Wii U displays at least the minute menu. Follow the "Booting without SD" section from the ISFShax tutorial for that. You only need to install the fw.img and can skip the ios_plugins part as you probably don't want to to boot the eMMC anyway.

Is it recommended for everyone to have this prepared to use "just in case" ?

No. Even if your Wii U breaks you can launch minute through de_fuse and install ISFSHax from there. I would even advise to not do this when not needed as the method is relative new, so there might be uncovered bugs in the process. In other words: Installing ISFSHax could brick your console! Chances are low but the longer you wait / the more other users tested it before you, the lower the chance of something bad happening.

Also why prepare for something that affects just a small userbase anyway? That's like purchasing NAND-AIDs to prepare for a console having a Toshiba eMMC.

tl;dr: Just think positive: When your Wii U works now chances are high it will just continue to work like that but even if the eMMC fails sometimes in the future you can fix this without beeing prepared.

What's the best way to back up the newly created rednand?

 

[SDIO]

What's the best way to back up the newly created rednand?

On Linux I would just use dd with the conv=sparse option on the mlc partition. On Windows no clue, you can probably use some third party imaging software. Maybe even Minitool or easeus can do it.
Also keep in mind some data like the tickets and settings are stored on the SLC. You can backup that with minute (like you already did)

Thanks, good to know. I just wasn't sure if those backups play well with wii partition formats

 

[SDIO]

In fact some tools will have a problem with that, if they try to back up as NTFS, but then they should just complain that the FS is damaged. You need a tool that ignores the FS and just does a 1:1 Sektor Image

 

[DrippyGoat]

This guide just saved me, I just fixed my "half bricked" Japanese Wii U. I just want to say thank you for taking the time to gather all this information and displaying it in this fool proof guide for the community.

 

[TheOneandOnly3780]

I would really appreciate if someone got the time to make a youtube tutorial about this step by step it will definitely help those who aren't native English speakers

 

[BeanBurrito]

Hi everyone, I had trouble when using "Patch (sd) and Boot redNAND" in minute. After using that option in minute it just gets stuck on "Searching for OTP store in patch... Searching for OTP store in plugins..." and nothing happens afterwards. Does anyone have a clue where I might have messed things up?

 

[SDIO]

Do you have the ipx files in the right place? What is the led doing? Did you already do the setup?

 

[BeanBurrito]

Do you have the ipx files in the right place? What is the led doing? Did you already do the setup?

Ah that was it I was missing the ipx files I accidentally deleted them! My Wii U is back from the dead thank you!

 

[Lapin]

While this works, I've been frequently having the error code 160-2203 at startup. It disappears after rebooting. I have no idea what could be wrong so I'll dump the log here of the latest crash to see if you can detect it. I'm using Aroma.

Try reinstalling the Home Button Menu (000500301001020A).
You can use nusspli for that

Hey, why does the Pretendo Miiverse have to shut down soon? Is there an alternative?

 

[DungeonS1]

Hey,
So I got a 2012/10 wiiU which I got for cheap with 6 month warranty, it’s a SK one…

I’m not really paranoid as it was factory reset and hasn’t thrown any errors. I have hacked it with Tiramisu (w/nand backup; slc.bin, slccmpt.bin, seeprom.bin, otp.bin) but was wondering what preventive measures I could possibly already take to be able to use this method if it were to fail?

 

[V10lator]

@DungeonS1 Use this to check what MLC chip you have: https://hb-app.store/wiiu/WiiUIdent

If it's not Hynix you're fine anyway. In case it is Hynix I also wouldn't do anything for as long as the Wii U doesn't show errors but you might be more paranoid than me?

 

[DungeonS1]

@V10lator
I did check already, I meant SK Hynix with “SK”, so would you recommend using this method once it starts showing it’s first error?

If it’s gonna throw a error while it’s under warranty from the seller I bought it from, I’ll just return it so I’m not really that paranoid lol.

If it throws an error after warranty I would like to use this method or buy a white console only and fix the black one with NAND-AID if I get around to it (maybe one day )

 

[Lapin]

If or maybe when you get the "160-0103" error, you should use this or the nand-aid method to make sure the console will still be usable, as the error indicates a problem that will get worse with time. Before that, don't do anything.

Hi ok is it me being stupid or what? using Pico to get to menu can do everything install network, dumps etc but cant get past the load boot1 payload sys just hangs there after selecting load, what am i missing or do i have one of those completely bricked doorstops?
as a side question is it possible to just replace the mem chip itself?

The latest stroopwafel fixes Wii VC:

Wii VC games (from he eShop or VC Injects) now works from the redNAND internal memory. Keep in mind that Wii VC is more picky about the SD card. So far Sandisk cards worked for me, but Samsung cards didn't. If the card is incompatible, it will hang on a black screen after the silver Wii logo.

I only tested one game so far, Sports Resort withe HAI IOS from Pikmin 2. Would be good to know if other games have problems and which SD cards work.

This is an awesome tutorial and solution! Thank you so much for making it. Now I can happily use my Wii U again after getting the famous error.

I have a question however! I accidentally made the partition for the MLC only 8 GB while I have a 32 GB Wii U. I wrongly assumed that I could download my already bought games to the SD card, but that's not the case. Is it possible to just increase the MLC partition size again to 32 GB or bigger using MiniTool Partition Wizard or will I then brick my Wii U again? At this moment I can't download games like Pikmin 3 anymore
