Hacking Contenthax - a Vulnerability in Wii U File System Verification

[TheCyberQuake]

The final thing I want to try to achieve for my custom redNAND launcher is a modified cfwboot.elf that will instead load from /wiiu/boot/fw.img instead, if that is even possible. The main reason being I want to be able to use the redNAND launcher to launch redNAND, but still have access to booting sysNAND WUPServer from HBL without needing to change fw.img files

Guys how do you open a command prompt on your wupclient? I have the folder called wupserver in my C folder but I cannot open it to put the command in?

Shift + right click in the wupclient folder

open the folder it is in, shift+right click in window, click something like "open command prompt here", then use the command "python -i wupclient.py"

Thanks for the help. I just keep getting "python is not recognixed as an internal or external command..." I have my wuphax folder in my main C drive.

Did you install python?

After moving to python 3.5 from 2.7.12 my upload speed went up significantly and it is no longer crashing when uploading files around 3mb, maybe it should be put in OP to make sure to use 3.5 since a lot of people still use 2.7 for compatibility and such?

Here is the Brainage with CFWbooter like you want. Load it from /wiiu/boot/fw.img https://mega.nz/#!NIswBArQ!xv1jF-NH662-R4VpSLOHx3lcl6xim2-sywECU0xkLW8

Can you give me your Logo + Meta.xml for Rednand on Brainnage For a US console Please

Thanks guys it worked! Actually it was that quick, lol I was sitting here at my pc waiting for it to finish uploading when I then realized it already had with the 0. Also I had to install the new 3.5 Python package to get it working, it would not work on version 2.7. Also can you only install over 1 copy cause I have noticed a Rednand app but would that go over the homebrew launcher.

Firstly I'm the one that created the custom rom.zip that boots /wiiu/boot/cfwboot.elf, which is the file you gave me a link to.
I meant I wanted to modify the cfwboot.elf file so that instead of reading from root it reads from /wiiu/boot instead. I already modfied and compile, I just have to test it real quick to see if it works. Thanks to @Maschell for linking to a github commit that helped me figure out what to edit.
I already uploaded my meta files and linked them about a page back

I also need the HBC logo and XMl for Kirby USA Thanks

This includes my meta files (meta.xml is for brain age US) and my modified rom.zip files that directly boot /wiiu/boot/cfwboot.elf for all three currently-exploited games. Currently I've only tested brain age US though.

You sure these weren't damaged when uploading? I cant view them in TGA viewer + they error with ??? when uploaded to WiiU. Im using the .tga files with Yoshi EUR/PAL, Maybe thats the problem?

BTW, The redNAND rom works just fine with Yoshi. Thanks.

How do you upload the meta files to go over brain age img? I was going to use the guys imgs from a few pages back it looked good.

I'll have to look into it, something may have happened between me using them and uploading them.

I'll dump the working ones from my wii u in a bit.

Is there any method to upload multiply files with wupserver? It's such pain in ass copying any file manually, by editing commands for each file.

you can upload a whole folder if you want its something like w.updir

 

[Reecey]

@BIFFTAZ Do you just put the meta files along with the rom etc.. into the rom.zip folder to upload them?

 

[BIFFTAZ]

Do you just put the meta files into the rom folder to upload them?

No, Meta files go in titleid/meta/. Only the rom goes in content.

Like this for brain age..

w.up("iconTex.tga", "/vol/storage_usb01/usr/title/00050000/10179C00/meta/iconTex.tga")

well I successfully changed cfwboot.elf to instead load fw.img from /wiiu/boot. /wiiu/boot is now where both cfwboot.elf and fw.img are contained for my custom redNAND launcher. I'll be uploading the modified cfwboot.elf and reuploading the working meta files in a bit (I have to download the working .tga images from my wii u). Once I do that I'll try looking into creating a github and then figuring out how to use it to show the small modifications I made to everything I modified so people don't complain about not showing source.
