Here we go, JSTypeHax is out !

https://github.com/WiiUTest/JsTypeHax

Currently in development, it's still not perfect. You may have to change delta in the code.

It loads HBL, I successfully haxchied a 5.5.2 ;)

UPDATE 05/21/2018

100% Working version, plus this is fast ! This can be used as a main entry point !
Enjoy !




BIG THANKS to @jam1garner @hedgeberg



How to use


Currently in beta test, you can follow this guide to use it:

  1. Prepare the needed files

    - prepare your FAT32 SD card with Homebrew launcher, and preferably Haxchi installer to get a persistent and more stable entry point for homebrew.
    Extract the homebrew launcher 1.4 on your SD card.
    sd:/wiiu/apps/homebrew_launcher/homebrew_launcher.elf

    - If you plan to install Haxchi, be sure you already have a compatible NDS game installed on NAND.

    - Prepare any other homebrew you want to use, for example Homebrew App Store.

  2. Find a web host or create your own
    Visit a website hosting it, like http://dlae.life/, http://wiiu.insanenutter.com, http://www.wiiubru.com/x or http://u.drg.li/
    or host the sources on your computer.
    If it's on your computer, you need python installed, and launch "startServer.bat" on windows, or use any other webserver you want.

  3. Run the browser hack on WiiU
    Clear your browser's data, launch the browser again.
    Open the server's URL in your browser, or your computer's IP if you are hosting it yourself.
    select Exploit
    If it freezes, shutdown and try this step again. It can be quick if you are lucky, or taking hours of retries...

    If it works, use that opportunity to install haxchi, it will be more stable.

    Note: As it is still in beta test phase, http://u.drg.li/ is hosting different versions of that exploit. You should prefer it over other currently available web hosts, and select exploits from delta 0 to 4 until one works (2 seems to be the one is working the most).

  4. If your screen goes grey-white but your console freezes, that's the correct delta, so keep trying that exploit number.

  5. Update the hack
    It's currently in development for stability, you might already have an outdated version. Check the "commits" number to know if it has been updated since your last check.
    Maybe the website you are using or your own files hosted on your computer are old. Try another website or update your files.

Real deal?

I am going to confirm that this is very much real, but honestly this really should be used for setting up Haxchi on 5.5.2, due to its lower success rate.

@JmpCallPoo awesome work! It's great to see more people working on exploits in this scene.

Lol, what do you expect? The first post by a random French guy. Plus, it says:
Code:
Tested on 5.5.1

"Successfully haxchied a 5.5.2" why don't you actually try it before dismissing something someone made just because he's French and hasn't posted something before.

That might as well be a lie and I can't test it when I'm on 5.5.1. It just looked weird with all the fakes lately.

So further reiterate this has been worked on with @jam1garner and @hedgeberg as well, both respected Nintendo hacking community members. This is not a fake.

Tagging @Cybernatus so he can update loadiine.ovh just in case he hasn't seen yet

Maybe we should hold off on that. This has a *very* low success rate. Again, like I've said before, I still think this should be only used for installing Haxchi until the exploit rates improve.

Well it won't be hard to say something like "very low success rate. Experimental to be used for HaxChi install only. Not daily use". If he doesn't update I'll add a section to loadiine.ovh/kafluke so people won't have to figure out how to self host.

My Wii U on 5.5.2 froze when loading this through Khan Academy, gonna try selfhosting
Edit: Will I need to edit the HTML file to add a payload or will everything work as-is?

selfhosting always had better compatibility for me with previous browser hacks.
seeing the sources and who did it, I'm sure it's real. though, it would be nice to get some comments to what has been done and were necessary to make it work with 5.5.2. (not everybody understand ASM code)

Thank you for your work.

edit:
what is wiiuhaxx_loader.bin?
I guess it's commented out, not used.
