If for some reason you can't perform one the options (missing NAND Backup, etc...) or don't wan't to, use one of the other ones in that Category.
If you need to find out the TitleID for an IOS look here under 00000007 and 000700xx: Virtual Wii titles.

vWii NAND Restorer

I have now released vWii NAND Restorer!
This is probably the easiest way to fix any vWii Brick if you have a NAND Backup!
If you don't have a NAND Backup check out vWii Decaffeinator! vWii Decaffeinator allows you to restore any IOS by downloading the IOS with a forced System Update.

Extract your NAND Backup

Some of the steps require your vWii NAND backup (SLCCMPT) and keys.bin/keys.txt/otp.bin.
Follow the steps below if you have a NAND Backup and need it for one of the steps.

DumpMiiNand Nand dumps don't work for me. I get an error when trying to extract them.
If you want to backup your vWii NAND properly use Wii U Nanddumper to dump your SLCCMPT and xyzzy to backup your keys.

1. Download the latest release of Wii U Nand Extractor. Linux or Mac users may be able to use WINE here.
   Extract the NAND Extractor.exe to a Folder on your PC.
2. Copy your nand.bin/slccmpt.bin and your keys.bin/keys.txt to this folder.
3. Open the NAND Extractor.exe.
4. Click on File > Open and select your backup.
   Your keys should be read automatically if they're called keys.bin/keys.txt.
   If not, go to File > Enter NAND Key and enter your NAND Key.
5. Go to File > Extract All and your nand gets extracted to a folder named like your backup file.

Setup FTPiiU Everywhere

Some of the steps require FTPiiU Everywhere.
Follow the steps below if you haven't set up FTPiiU Everywhere already and need it for one of the steps.

1. Download ftpiiu everywhere.
   Mocha users should use this version. Extract the .zip to the root of your SD Card.
   Haxchi/CBHC users this version. Rename the ftpiiu.elf to ftpiiu_everywhere.elf and place it on your SD Card under "/wiiu/apps/ftpiiu_everywhere/".
2. Run CFW on your Wii U and go to the Homebrew Launcher.
3. Start FTPiiU_Everywhere.
   Your IP should be displayed there.
4. On your PC start a FTP Client like FileZilla.
5. Enter your IP only up to the colon in the "Host:" field. And the two numbers after it in the "Port:" field.
   Leave everything else blank and press "Quickconnect".
6. You should see your Wii Us Nand. Do not modify anything here or you can brick!

IOS Brick

If you have a corrupted IOS (for example when you tried to install Wii cIOS) follow one of the options below.

vWii still working
If your vWii still works but one of the IOS is broken follow one of the options below.
The steps below require a clean .wad of the corrupted IOS on your SD Card. You can dump it from another console using Yet Another BlueDump Mod.

Homebrew Channel working
If your HBC works (you still have IOS58), run a wad manager (for example Some YAWMM Mod) to reinstall the broken IOS.

Homebrew Channel not working
If HBC doesn't work, is missing or can't be reinstalled using hackmii installer, BUT you have IOS58 and forwarder channel (forwarder for USBloaderGX, Wiiflow or any other homebrew) follow the steps below.

1. On your PC replace the target's boot.dol with the wad manager's boot.dol (for example Some YAWMM Mod)
   
   
2. Install the clean vWii IOS using the wad manager.

If HBC doesn't work, is missing or can't be reinstalled using hackmii installer, and you don't have IOS58 or any forwarder channel installed follow the steps below.

If you have vWii cIOS 236:

1. Perform a game exploit or use wuphax to launch SD:/boot.elf.
   Replace Hackmii installer's boot.elf with the boot.elf of this wad manager.
2. Your wad manager should start.
3. Reload to cIOS236, which gives IOS installation permission, and install the needed clean vWii IOS.

If you have vWii d2x cIOS:

1. Perform a game exploit or use wuphax to launch SD:/boot.elf.
   Replace Hackmii installer's boot.elf with the boot.elf of this .7z.
   Place the V58i.wad on your SD Card.
2. Your wad manager should start.
3. Choose any d2x cIOS slot, which only has permission for non system WADs.
4. Install the special channel (V58i.wad).
5. Return to vWii system menu and launch the newly added channel.
   That channel contains a wad manager which can now install IOS files thanks to granted AHB access.

vWii not working
If your vWii is not working but one of the IOS is broken follow one of the options below.

No NAND Backup required
The steps below create a WiiU WiiVC channel with a vWii Wad Manager to install clean versions of the vWii IOS. Credits: @Cyan
The steps below require a clean .wad of the corrupted IOS on your SD Card. You can dump it from another console using Yet Another BlueDump Mod.

1. Download the WiiU VC injector script (requires .NET framework). Linux or Mac users may be able to use WINE here.
2. Download this (v)Wii Wad manager.
3. Download WupInstaller_gx2 and copy the contents to the root of your sd card.
4. If you need to reinstall IOS58, you need the clean vWii IOS58 v6432.wad
   if you need to reinstall any other IOS, you also need a clean vWii IOS wad for it.
   copy the wad to "SD:/wad/".
5. Launch the TeconMoon's WiiVC Injector.exe.
6. Select "Wii Homebrew Injection" mode.
7. Click on the "Game..." button, and select the "boot.dol" you got in step 2.
8. You'll have to select some banners/icon that will be used for your created channel. They will be displayed on your WiiU system menu.
   I updated the ones provided by @antnida. You can download them here. Or you can download the original ones by antnida here.
   Or if you want your own pictures, you'll have to choose 2 different tga pictures with the right size (the script will convert to correct tga format automatically).
   You can find more samples here.
9. On the "Game Pad/Meta Options" tab,
   You'll have to choose a name for your created channel, so let's call it "vWii wad manager" or "YAWMM".
   It should generate a random titleID for you (this is good, don't try to change it).
10. Go to "Build Title" tab
    Fill in the text fields the WiiU common key (google) and the "Rhythm Heaven Fever" USA game key (wiiu key website, google it too), and when all requirements are displayed in green, click on the "Build" button to build the channel.
11. Put the generated files into your SD:
    SD:/install/wiiWadmanager/<Put.appAndOtherFilesHere> .
12. Launch your WiiU in CFW mode (CBHC, haxchi, or anything else which is NOT redNAND, like sigpatcher2sysmenu or sigpatcher2hbl).
13. Launch WUP installer GX2 from Homebrew launcher and install the generated channel to your WiiU.
14. Still with CFW enabled, launch the installed channel.
    Your WiiU will boot in vWii mode, with the WAD manager from step 2 launched automatically without going through the vWii Homebrew Channel nor even requiring IOS58.

Install the clean vWii IOS with the WAD manager.
Done!

Spoiler: FAQ

• Problem with the injector script ?
If you have issue using the injector script program, please report your problem here :

CRC32 : 68aa72fd


• How to be sure you found the correct key?
The injector will change the color of the field from red to green.
it will not let you create the channel with a bad key.


• Why use the script injector? can't someone else who already created the channel share it for others to use?
No, sorry. you need to build the channel yourself as you can't share ready to install channels here.
WiiU WiiVC contains nintendo's copyrighted code and files.

NAND Backup required
The Paths below are for IOS80 if you installed a different IOS you need to find the Path for it here under 00000007 and 000700xx: Virtual Wii titles or overwrite the whole "\slccmpt01\title\00000001\" folder with your backup which will replace all your titles with the backup.
For the second Part of the Id look at the Region column.

1. In FileZilla locate to "\slccmpt01\title\00000001\00000050\".
   Go to the same path in your extracted NAND folder.
2. Replace the content folder with the clean one from your backup.

vWii System Menu Brick

If you have a System Menu Brick (for example when you tried to install Priiloader) follow the steps below.
The steps below require a extracted NAND Backup, if you dont have one follow these steps.
The Paths below are for my EUR Console you need to find the Path for your Region here under 00000007 and 000700xx: Virtual Wii titles.
The 00000007 may be US, my European one only has 00000001.

1. In FileZilla locate to "\slccmpt01\title\00000001\00000002\content\".
   Go to the same path in your extracted NAND folder.
2. Replace 00000022.app and 00000023.app with the clean ones from your backup folder.

Brick from corrupted Channel

If you have a corrupted Channel (for example when you tried to install Wii Channels) follow the steps below.

1. In FileZilla locate to "\slccmpt01\title\00000001\<TitleID>\" without the <>.
2. Delete the folder

Replace SLCCMPT

If the steps above didn't helped you or you're just lazy there is a quick and dirty way of replacing your SLCCMPT.
The steps below require a extracted NAND Backup, if you dont have one follow these steps.

1. In FileZilla locate to "\slccmpt01\".
2. Delete every folder in it.
3. Copy every folder of your NAND Backup in there.
   You now need to set the right permissions for the folders.
   You can do this by simply running slccmpt fixer. More information here: https://gbatemp.net/threads/slccmpt...ctly-from-your-console-testers-needed.560506/
   If this does not work for you follow the steps below:
   
   Spoiler: Using wupserver

   [*]Download MochaCFW and this config file for it (Right Click > Save As...).
   [*]Copy the contents of the mocha.zip to the root of your SD card and the config.ini to the /wiiu/apps/mocha/ folder on your SD card.
   [*]Download Python (If the latest version doesn't work try using Python 2.7) and save the wupclient.py on a folder on your PC (Right Click > Save As...).
   [*]Open wupclient.py with some kind of text editor and replace 192.168.0.197 in line 30 with your Wii Us IP and leave the port as it is.
   [*]On your wii u start the Homebrew Launcher (CBHC Users have to press the Home button while boot and start the Homebrew Launcher from there).
   [*]Run MochaCFW and you should return to the Homebrew Launcher. You're running now wupserver in the background.
   [*]On your PC run Command Prompt and type "cd <PathToFolderContainingWupclient.py>" without the <>. Press Enter to continue.
   [*]Type py -i wupclient.py and press Enter again.
   [*]Enter the Command below:
   

   mount_sd()
   mount_slccmpt01()
   def do_folder(path):
       results = w.ls(path, return_data = True)
       for result in results:
           w.chmod(path + '/' + result['name'], 0x666)
           if not result['is_file']:
               do_folder(path + '/' + result['name'])
   
   do_folder('/vol/storage_slccmpt01')
   unmount_slccmpt01()
   unmount_sd()

This will set the correct permissions for the folders.

Info

This is still WIP and I will try to keep it up-to-date.
If I did something wrong or missed something please let me know! Hope that it will help someone.

I think I've heard of that as well. cbhc is up to 1.6 iirc, and I think the person was updating from 1.3. also, @FIX94 said that there's a rare chance that cbhc might not install. it usually doesn't brick in that even though.

[godreborn]

I don't think he was able to pinpoint the cause, but I'm pretty sure he said just try again. I guess it's possible it could brick then, but I dunno. never happened to me in the two times I've installed cbhc and even uninstalling it no issues.

--------------------- MERGED ---------------------------

even uninstalling, then deleting the game posed no issues. I was originally using yoshi's island with cbhc, but I changed it to brain age. I tried making my own meta.xml for brain age, because I forgot to ftp it like I did yoshi's island. I used yoshi's island's as a template.

 

[Flump]

I am talking about vWii Decaffeinator it's dangerous to update especially if you're on 5.5.2 cbhc or 5.5.1

This is the funniest thing I have read in ages.

Decaffeinator literally fixes the SLCCMPT which is completely separate from the SLC.

As for WiiU updates concerning CBHC the major thing that will happen is the xml will be reset so that instead of auto booting CBHC any more it will revert back to system menu and CBHC will have to be reinstalled even tho CBHC is still technically installed, just to replace the xml.

This has nothing at all to do with the SLCCMPT which Decaffeinator is fixing. As for testing with CBHC, been there and not only wore the T-Shirt but probably produced the T-Shirt

[christianacqua]

a question, is it possible to enter the vWii with a bricked Wii U

 

[godreborn]

not likely. you can load the vwii with cbhc, but it would have to have some sort of functionality.

 

[christianacqua]

if you can enter vWii whit CBHC can you also enter the homebrew launcher? If you are using the homebrew launcher you could try to unbrick the Wiiu via FTPIIU

 

[GaryOderNichts]

if you can enter vWii whit CBHC can you also enter the homebrew launcher? If you are using the homebrew launcher you could try to unbrick the Wiiu via FTPIIU

Depends on how the Wii U got bricked.

[Alexander1970]

Good Morning.

vWii not working
after i done everything i get a code error 160-2793 can anyone help?

Please can you be so kind and tell us
"I done everything"
a little more detailed please.


Your Error Code could be maybe the Result of an "bad" VC Injected Wii Game for Example....

Thank you for your Help.

Hi, my vwii is getting the black screen of death after installing wads to fix usb loader gx (it wasn't detecting my usb). I still could play wii and gamecube games on the Wii U through Wup installer with no problem but I don't have access to the Wii menu. It's there a way to delete the wads that bricked my vwii or should I just let it be and continue using Wup installer to play wii/gc games?

 

[zenaro147]

Did someone know how to solve this vwii issue?
I can boot the vWii using the channel icon or holding B

But the console turns off right after the health and safety screen

I tried to run decaffeinator on Light and Agressive mode (and updating right after the program asked), but the issue persist
I also tried to replace my slccmpt but didn't work

Is my vWii was bricked forever?

(just to mentioned the past things, It was working before I format factory my console .. it has only tiramisu and aroma... I don't think it have some other method before. According to the seller, this is the first mod on this console )

-------- EDIT ---------
I noticed on Syslog a lot of messages like "MCP: rear usb error"

I tried to boot on vWii, and after the console shut down, I turned on and enter on Recovery Menu.... than I noticed these messages, apparently during the vWii boot... this could be the cause?

And yes, one of the rear USB is not working... actually seems a short circuit

I used a multimiter to check the continuity, and seems that the 5v line have some kind of short

There is almost to resistance between 5v and GND (it beeps, but not full 0)... and I got some low resistence between the data lines and GND (shows 500)

In a working port, I don't get continuity between 5v and GND or between 5v and the data lines

Hello, I have a question about the wii u nand extractor. How do I find my nand key?
