orboditilt updated JumpCallPop's JSTypeHax for the Wii U firmware 5.5.2, 5.5.3, 5.5.4 and 5.5.5 and made it more stable! You know, the old one worked but needed a lot of tries and this was pretty annoying. So this new payload now works better, worked for me on the first try!

If you already have Haxchi installed, this is NOT for you!


Installing Haxchi is no longer recommended! Please use Tiramisu!


Instructions

  1. Grab the Wii U Homebrew Launcher ELF and extract it to your SD card (make sure it is formatted as FAT32, not exFAT!)
  2. Grab the payload.elf file and extract it into "SD://wiiu/"
  3. OPTIONAL, but RECOMMENDED: Extract the Haxchi installer to your SD card and make sure you have a compatible haxchi game (e.g. Brain Age)
    1. Recommended: Use Tiramisu
  4. Open the Wii U internet browser and clear the browser data through the settings (recommended)
  5. Navigate to u.wiidb.de and click the big "HAXX" link
  6. The Homebrew Launcher should load! From here you should install Haxchi to make your life easier.
Troubleshooting

This can happen, just try again. Also clear your browser settings, set u.wiidb.de as a bookmark, close the browser and reopen it again. Don't do too much other stuff in the browser or it won't work!
Format your SD card in FAT32.
You are missing the payload.elf file.

Host it yourself

I recommend only using u.wiidb.de as it will always be the latest version! Ensure you have PHP installed and enabled.
  1. Grab wiiuhaxx_common and extract the files to a directory "wiiuhaxx_common"
  2. One folder above, download all three PHP files from JSTypeHax and place them in there
  3. Place code550.bin in the same directory. Compile it from here or download a precompiled one here
So you have:
Code:
| ROOT
|- code550.bin
|- index.php
|- index-hax.php
|- wiiuhaxx_common_cfg.php
|- wiiuhaxx_common/
|-- wiiu_browserhax_common.php
|-- wiiuhaxx_loader.bin
|-- wiiuhaxx_rop_sysver_532.php (not really needed)
|-- wiiuhaxx_rop_sysver_550.php
|-- wiiuhaxx_searcher.bin

I switched to this (from loadiine) and now I can no longer launch the installed homebrew app (blackscreen freeze). Mii Channel and browser still works

What do you mean by "the installed homebrew app"? To be able to start any custom installed channel, you need a CFW.

I am using mocha cfw, and everything worked before using this exploit

You're right:
Browser exploit -> mocha -> hbl channel does not work, but
Haxchi -> mocha -> hbl channel also doesn't work...

Which entry worked for you this? What do you mean by "loadiine"?
And why exactly are you using the channel version (instead of simply using the mii maker?)

Just tested the "old" version of the exploit and it indeed started the channel, while the new one doesn't.
I think the "old" one uses the (outdated) hbl 1.3 installer, that is the only difference.
I'll look into it, thanks

Until then I would suggest you to simply use the mii maker. Using the channel after the browser exploit is pointless anyway.

This thread really isn't getting enough attention. Probably the biggest news on the wiiu scene in months.

For those of you using a web exploit and not haxchi/cbhc this has a 100% success rate. Tested it 13 times myself on HB 1.3 and HB 1.4 and I've had other helpers testing it also with 100% success rate.

Great work by all involved.

Spent 4hours on it, hope it's good enough.
