BluUBomb - A primary Wii U entrypoint via bluetooth

MikaDubbz · May 17, 2021

This is great, to have an entrypoint that doesn't require the internet browser means the system should be future-proof to hacking should all internet services on the Wii U one day be shut down.

Does this mean I won't have to buy a certain DS game on the eshop to hack my wii u?

Yes, this is just to get your foot in the door.

That's not really a concern, is it?

Even if all internet services on the Wii U are shut down, your browser still works.

Nice to see some WiiU love!
It's always a thrill to see stuff developed for it and how it evolves

Will keep an eye on this!

I pushed a small update, which should fix pairing on Intel Bluetooth chips.

You never had to buy a DS game to hack your Wii U.
You can just use the browser exploit without installing haxchi.
But as I already said, BlueBomb won't do any permanent modifications.

Well the Wii browser doesn't work anymore, seems feasible the Wii U browser could one day become useless as well.

Not really.
As long as you can setup a localhost that the U browser can read, you're golden.
The only way in which the U browser would "stop working" would be because most web pages get updated with new SSL encryption keys or some other new stuff security based, but that's dependant on each webpage you visit, not really the WiiU browser at fault.

Many pages don't work on WiiU anymore due to the browser not being updated to recent versions, and the SSL stuff being outdated.

you can self-host, but I don't know if post 5.5.1 requires new files. I have the 5.5.1 and below files on my computer, and you can host them with kws on an android phone or with the pc and xampp, which is where the files are now. I discovered that kws even works with android 11+, which is what I'm on.

yep, still works (this is via my android phone to the computer with kws):

I've already had to replace my left joycon analogue and only had it for 4 months aswel. And now my right joycon stick keeps saying its detached while playing in handheld mode... I don't even know what that issue could be considering i can't find anyone else having the same thing happening

Try switching the right and left joycons to see what happens.

I thought all Wii U can be soft modded without buying anything unless I was wrong?

You can use the browser, but haxchi is more reliable.

BluUBomb exploits the Wii U's bluetooth stack to gain IOSU kernel access via bluetooth.

Not to be confused with BlueBomb for the Wii and Wii Mini.

What does this mean?
This means you can get IOSU code execution by only pairing an emulated Wii Remote to the system.

This should be useful to fix a few softbricks on the Wii U side.
You don't need a working browser or Mii Maker.
if you've messed up with regionhax and can no longer access the browser, BluUBomb should be able to fix this as well.

The BluUBomb repository contains a few different kernel binaries for different purposes:
arm_kernel_loadfile
Launches a launch.rpx from the root of your SD card on the next application launch.

arm_kernel_fw_launcher
Launches a fw.img from the root of your SD card on the next OS relaunch (for example when exiting System Settings).

arm_kernel_region_free
Applies IOSU patches to temporarily remove region restrictions.
This should be helpful if you've locked yourself out of your applications due to permanent region modifications.

Check out the repository for additional instructions:

My network card seems to have a problem when running the exploit, the errors appear in the screenshot

I'm a little confused is this a new hack or just can fix your Wii U?

Its what it says, ENTRYPOINT.

basically its a new backdoor key, who knows what it can do, but we do know it can be used to fix some existing issues from fuckups.

E1ite007 · May 17, 2021

Howdy.
In the new version, this happens when trying to disable the simple pairing mode:

It doesn't deactivate, and it always stays as "Enabled".

ertaboy356b · May 17, 2021

Is this the same entry point with the Wii Mini?

Well I only mentioned it because I've seen others worry about the Wii U losing the browser entry point in the future. So I'm just saying this extra one just gives us all the more comfort moving forward, knowing that there are alternatives.

haven't read through the rest of the thread yet, but this looks like your bluubomb is not an executable file. You're on wsl? You extracted this from a .zip file? When you right-click on that .zip file and look at properties, is there a checkbox near the bottom that gives you the option to "unblock" it?

chmod +x bluubomb

EDIT: ok, I see someone got you there already.

Sadly not, you can't pair a Wii Remote on the error screen.

There is one way to pair a Wii Remote to a Wii U without the Wii U syncing working, and that is to pair it to a PC using a bluetooth adapter with a spoofed MAC address set to the MAC address of the Wii U's bluetooth module.

I softbricked my Wii Mini when i had it autoboot the homebrew channel and used my Wii Remotes on other systems. This made it so i had no way to navigate the homebrew channel and was stuck. As a last ditch effort I disassembled the Wii Mini, wrote the bluetooth adapter's MAC address down, then spoofed it using a USB bluetooth adapter.

unfortanately this does no good for CHBC bricks unless the emulated remote could have the Wii U Bluetooth MAC address manually specified vs. relying on syncing.
