Simple guide to install d2x cIOS on vWii + backup NAND and keys
Last update: April 29th 2016
Still a valid hacking procedure as of September 2016.
(see Changelog at the bottom of the post)​

What does it do?:
This guide shows you how to install cIOS into vWii (aka the Wii-mode of Wii U) and backup vWiis keys and NAND.
cIOS is needed to use backuplaunchers like Wiiflow and USB-Loader GX.
This does not enable any hacks in Wii U-mode!

Note: You already need to have Homebrew Channel installed on vWii to use this guide (use one of these exploits)!
​

Lets go:
Download the following package:
www.mediafire.com/?n2zl8v5kn288j9d
(Mirror at the bottom of the post)
All files are up-to-date (as of april 29th 2016)!
Note: To avoid errors, only use the files provided in this archive!
Don´t mix with other d2x-installer versions, meta.xml files etc.
Don´t worry, everything is up-to-date and the latest and greatest version.

It contains:
- Dump Mii NAND v1.2
- d2x-v10-beta53-alt-vWii
- d2x-v10-beta52-vWii
- FIX94s d2x cIOS Installer 2.2 mod

First we make a backup of your vWii NAND and keys:

1.) Extract the contents of vWii_cIOS_apps_20131218.zip to the root folder of your SD card.
Note: Make sure that you don´t have any original Wii system files (like wads) on your SD Card!
d2x installer could accidentally use them for installation and brick your vWii!
Also make sure that you have at least 528MB of free space on the SD Card for the NAND dump.

3.) Launch Dump Mii NAND from the Homebrew Channel.

4.) The NAND and keys dumping will start automatically (the NAND dump will be stored in sd:/nand.bin, the keys in sd:/keys.bin).
Note: DON´t use this dump on an original Wii!

5.) When finished (depends on the speed of your SD Card), the Wii U will reboot.

5a.) (Optional, but recommended step.)
Dump your IOS one-by-one to wad files for possible semi-brick fix (for more info read this thread):
I.) Download YetAnotherBlueDumpMod from here.
II.) Copy the files to your SD card sd:/apps/YetAnotherBlueDumpMod and launch the app from the Homebrew Channel.
II.) Go to System Titles and dump each IOS individually to a wad.
When prompted to fakesign the ticket or TMD, say No to both.

It's a tedious process, but it could save you a lot of trouble in the future.

If you don't have CLEAN (non fakesigned) IOS, you won't be able to fix semi-bricked vWii.
You can't create non fakesigned wads from a NAND dump or from using ShowMiiWads. You NEED to use YetAnotherBlueDumpMod.


Now we install d2x cIOS:

6.) Launch d2x cIOS installer from the Homebrew Channel.

7.) Choose which d2x cIOS version you want to install, beta52 or beta53-alt.
If you don´t plan to use EmuNAND, i recommend beta53-alt.
Note: For info about the differences between beta52 & beta53-alt click here.

8.) Select cIOS : <d2x-v10-beta53-alt-vWii> (Alternative: beta52)
Select cIOS base : <56>
Select cIOS slot : <249>

9.) Press A to install and wait for installation to finish.

10.) Press A to continue.

11.) Select cIOS : <d2x-v10-beta53-alt-vWii> (Alternative: beta52)
Select cIOS base : <57>
Select cIOS slot : <250>

12.) Press A to install and wait for installation to finish.

13.) Press A to continue.

14.) Select cIOS : <d2x-v10-beta53-alt-vWii> (Alternative: beta52)
Select cIOS base : <58>
Select cIOS slot : <251>

15.) Press A to install and wait for installation to finish.

16.) Press B to Exit.

17.) Launch newest Wiiflow or USB-Loader GX or CFG USB Loader MOD from the Homebrew Channel.
Note: To copy game images from PC to your external HDD with the correct folder structure, use Wii Backup Manager.
To fix the 4:3 aspect ratio bug of the Homebrew Channel, see FAQ & Troubleshooting section.

18.) Read the FAQ & Troubleshooting section carefully!

19.) Happy gaming!

FAQ & Troubleshooting:
- there is currently no Bootmii for vWii, so we use Dump Mii NAND.
- there is no Hermes cIOS 222/223 for vWii (don´t install the Wii version!).
- connect your HDD to the upper back USB-Port.
- you need a Y-USB-Cable for some 2.5" HDDs to properly work (even when they worked on the original Wii), because the Wii U USB-ports have a lower power supply.
- if HDD gets detected but no games load or HDD "clicks" you need a Y-USB-Cable
- to prevent the HDD format message on bootup, use U-Stealth.
- some HDDs don´t work with cIOS 249(base 56), so change the cIOS to 250(base 57) or 251(base 58) in your USB-Loader.
- to fix the 4:3 aspect ratio bug of the Homebrew Channel use JoostinOnlines HBC Forwarder or tueidjs aspect ratio fixer (tueidjs fixer doesn't require installing a wad to the console, it's a homebrew to launch from Homebrew Channel before launching other homebrew).
- to (un)install wads i recommend YAWMM_EN 0.5e (english Version) or YAWMM DE 0.5e (german version).
- if you want to start installed wads like VC/Wiiware from SD card, you need to patch IOS80 (system menu), use this thread for guidance.
Note: This is dangerous! If you f*** up IOS80, you will get a brick!
Only use the patch if you know what you are doing!

- don´t install Priiloader, it will brick your vWii!
- don´t install original Wii Channel Forwarder, they will freeze on startup! Use the ones from this thread. (For WiiFlow you can use the official Channel Installer)

Many tools/installers/wads etc. that worked on the original Wii will brick vWii!
So be very cautious on what you install!

[JoostinOnline]

I'm (slowly) translating YAWMM DE to English, if anyone wants to help.

 

[[Truth]]

Changelog:
01. June 2013: Added YAWMM_EN (english version) to General FAQ (thx JoostinOnline and Fix94).

 

[Warlord698]

I can't help but wonder why CFG USB Loader isn't included in the last step, i have yet to have any problems loading games using the latest version on vWii and has no problems reading from a NTFS formatted partition instead of a WBFS

 

[[Truth]]

Simple, i never used it.
Post me a link to the latest Rev and i will add it to the first post.

 

[jjuanml2]

Before I get started you state" You must have homebrew use one of the exploits". When I go to try letterbomb I'm kind of stuck at getting the mac address. On Vwii I don't see the internet options? Would you mind guiding me just a bit at possibly even though this is the easiest part?

You can't use LetterBomb on the vWii.

 

[jjuanml2]

The smash exploit worked. Cool, now I can begin. Ok everything is done, Now I just need to find out how to install wads. Does anyone mind giving me a quick link on some tutorial about wad managers, if you have time? Thanks.

 

[JoostinOnline]

There is a wad manager in the General FAQ at the bottom of the post.

 

[panmusic]

I do not know if my question has been answered before.

I followed this guide and managed to obtain the nand keys with xyzzy 1.2.2 and dump the nand filesystem with FS-Toolbox 0.4d.

The question is how can I restore vWii if something goes wrong in the future?Is there a way for this?

No, at this point you can NOT.
If you have a full brick, you are fucked.

So please: read before you install any wads in vWii, it´s dangerous!
Read my guide to the end and understand it!
There is a link for wad manager and a link for forwarder channel that work in vWii.

But as i said in the other thread:
If you continue to just install everything you find without having a clue what it does and if it´s compatible with vWii, you will have a brick sooner or later.

Thanks for your answer!

I have not installed anything and thank God I do not have a full brick. (The only wad I am temted to install is the LostWinds wad because this game can not be transfered normally.But even that,I am afraid to try it!)
But,as the Wii U scene evolves I want to know if there is a way to restore the nand if something goes wrong in the future.

I really hope that someone finds a way for this!

Whoops, i´m sorry, i thought i was replying to jjuanml2.
Everything after the first two sentences was directed to him.

 

[Vegeta Prince Sayan]

Can I install any VC and Wiiware game wads using YAWMM_EN on my vWii, or the wads have to be especial for vWii like the Channel Forwarders? tks!!

You can use the normal ones, but some will not work.

sometimes I just want to slap people...

 

[kp_centi]

Why isn't this stickied?

 

[Thundernad]

Is there a mirror site for http://bootmii.org/download/ ?? It's been down for several days and I need to install the homebrew channel.

 

[Warlord698]

i completely forgot

http://gbatemp.net/threads/configurable-usb-loader.147638/
it is one of the stickied threads in the Wii - Backup Loaders sub forum

 

[lucasgc]

Hi all,
Could I install a cios 223 Hermes using this method? I wanna play rock band with my drums but it isn't being recognizing and I know that if use this cios on wii works fine.
Thanks

 

[Brandts]

What a great clear guide. I stepped through your guide without any problems and everything is working perfect. I just have a question about USB Loader GX. From my Wii I was used to run USB loader GX from a channel. For the version you posted, I always need an SD-card. Is it still possible to install it as a channel or will this brick my WiiU?
