Hacking Contenthax - a Vulnerability in Wii U File System Verification

[TheCyberQuake]

Hi guys!
I found a very simple way to use loadiine directly without use browser and without have Wii U connected to internet
You have to compile the IOSUhax from the @TheCyberQuake 's Haxchi Mod Custom redNAND Launch Title thread, then choose your DS game version (but only HBL version) and replace it with WUPserver
This loads the homebrew_launcher.elf from SD:/wiiu/apps/homebrew_launcher/ so then paste the .elf from loadiine GX2 and rename it to homebrew_launcher and when you open it it loads loadiine!
Bye!

I actually plan on making another custom haxchi that simply runs /wiiu/contenthax.elf, that way people can make it launch a custom app directly.

Is this something Nintendo could easily block by updating hachihachi? Or is it more to do with the Wii U firmware?

Guess what I'm really asking is, if people wait around too long to grab a compatible game is it possible they might be out of luck if there's a silent patch server side?

EDIT: Also, does installing this mean homebrew can persist even if web exploit gets patched in a new update?

They can't patch this without releasing something like 5.5.2.

Yes. But if they patch the stagefright exploit, I doubt they won't patch haxchi as well.

Okay, in the two days that I've been away from this thread it has increased like a tenfold with over 600 new posts and all, don't feel like reading through all that, can someone give me a summary about what caused this thread to blow up in these two days so quickly?

FIX94 got haxchi to load the homebrew launcher, ported it to more DS games, and people are hyped as fuck. That's your TL;DR

Is there a list of some kind to see which games it has been ported to?
In any case thank you!

To be fair, the short tutorial in OP is pretty much what we do, the only difference it the path being different depending of the game. Other than that, it's just a matter of injecting the rom.zip with wupclient.py

I was thinking about that too. Is there really nothing else that I must do beforehand?

The list of games supported can be found in the readme: https://github.com/FIX94/haxchi/blob/master/README.md

Brain Age, Yoshi's Island Ds, Kirby Squeak Squad and Wario Ware Touched for now.

You must run fix94's fw.img in order to boot in wupserver mode. Once you did, you can inject the rom with wupclient.

just pushed up some more changes to haxchi.
-fixed screen corruption when loading homebrew launcher by properly clearing the screen
-modified IOSU exploit to load from high MEM1 to not run into existing memory and crash
-updated homebrew launcher loader to follow dimoks latest commit and be ready for 1.4 .rpx loading

Also I already have a plan for selecting what to launch by holding buttons on boot and a custom config file, but this for now gives it all some more stability and faster loading times which is good.

Will there be an updated tutorial or will we need to wait a day or so for one? I think Fix94 said something was in the works? What I want to know is once we install HBL to SysNAND, do we need to run CFW every time?

Thanks you for your work! Maybe you (or dimok in HBL) can add a check to launch mimaker insead of HBL if it are running, so we can re-launch HBL from the haxchi.

There will be a tutorial, eventually. Actually, I might rework op later today, for better instructions. But like FIX94 said, it's better to wait if you are unsure of the procedure, or if you can't get it to work, for any reason.

You ARE the MASTER!!!
Thanks for all of your hard work

And the second question, once we get HBL installed, will we have to run anything to get it to run beforehand? Okay
