    IS IT OUT?! (( No )) -- Updated 2/1/2016 12:16AM MT (UTC -7)

    Also, check here: http://gbatemp.net/members/hykem.349530/

    If you accidentally updated to 5.5.1, it appears that Yellows8's .mp4 exploit has NOT been patched (confirmed by Crediar).

    Hykem say's 5.5.1 is OK (But update at your own risk !)

    Just what is this thing, exactly?!

    Hykem has developed an exploit that can be launched through the Wii-U web browser that can take full control of the system's iosu. From there, we can gain control of the kernel as well and have unrestricted access to the entire system!

    What do I need?
    - A WiiU on any firmware up to 5.5 (Any unit in any store will have this)
    - An SD Card
    - A WiFi connection for the WiiU to connect to
    - *A compatible External Hard Drive (*Optional)


    Phase 1: Setting up TubeHax DNS (Thanks Smea!)
    TubeHax DNS!

    Phase 2: Loading the Exploit (Coming Soon!)
    Exploits! Yay!




    So, should I update to 5.5 ?
    Warning: Spoilers inside!
    TL;DR -- No, don't update. Stay where you are.


    What can this hack do?

    I SET UP TUBEHAX AND GOT THIS SYMBOL! DOES THIS MEAN A NEW FIRMWARE IS OUT?! OMG EVERYONE PANIC!!!

    [​IMG]

    Calm down, it just means that the WiiU tried it's periodic check for an update file and failed because you have TubeHax DNS set up PROPERLY.

    Hykem isn't currently accepting donations, but he wishes for you to donate to the developers that follow up with this exploit and their efforts!

    I have a few questions about this:

    - What can IOSU exploit do?
    - Is Kernel exploit needed or can it do stuff Kernel can and more?

    Thoughts appreciated :)

    Even if it's buried. I believe the author of the exploit should be the one posting a thread about his own exploit.

    Ok, from what I read, it does not need Kernel exploit. I am still confused what IOSU can do? What is it for and what can happen/become of it?

    Sorry guys, I have another 13 hours of a car ride before I get to my new place and this stupid Verizon tether isn't working on my Note, I'll answer questions when I arrive if nobody answers before I do. The forums work like butt with the Android browser and not at all with mobile firefox lol.:)

    Well he didn't, and it wasn't on the front page, so the general populace doesn't know about it. So I figured I would make a post. What are you the gbatemp.net police or something? Chill out.

    I hope 5.4 is the priority behind 5.5. I gave up on waiting for a 5.4 kernel exploit so this is probably as good as it'll get.

    The general people do not have to know about it as it will just attract unwanted attention and a flood of threads asking stupid questions. @SonyUSA

    I honestly did not mean to make a fuss, but based on your reply, you seem quite the emotional type.

    Yeah I'm on my period. What's your excuse? The gbatemp.net owners are more than happy to take the added user base because that means more revenue. If I was worried about stupid questions I wouldn't write guides and answer those questions that I prompt because of my actions.

    I teach the first wave of people, then they teach the wave after them when they repeat the same questions. It works itself out quite nicely.

    It will be ported to the 5.2-5.5 range by first release I'm sure since that's where almost everyone is sitting. The rest can come later, depending on how he feels about porting and adding the obfuscation.

    iosu is responsible for cert/app signing and security, so possibly anything -you- may want to do could be done with this exploit (read: warez).

    "
    Alright, for those of us not familiar with Wii U hacking, IOSU is basicallly the operating system of the Wii U when it runs in Wii U mode. It’s what we could compare to the “native” world on the PS Vita per opposition to the PSP Emu. In particular, IOSU is responsible for security checks on the Wii U, verifying that you’re not trying to run unsigned code, etc.

    So yep, having compromised IOSU is a big deal."

    This may have already been posted, but in the middle of a stormed out thread that a lot of users don't even look through. So thanks OP for posting this as a topic. This is really good news for a lot of people, so we can get ready for this by blocking updates and planning ahead for it.

    I was actually thinking of posting this as an individual thread myself.

    I mean... don't read too much into this, but I'm keeping my fingers crossed for Emunand ;D

    Immediate uses: RPX size restriction won't be a thing anymore, so expect that very soon.

    Reading Hykem's post it seems like he wants to release on Christmas, but it isn't likely given all the stuff he still has to do (and software development is always fraught with delays).
    Still, I approve of this hype thread because we haven't had one in a long while. ^^

    Sorry for being "that guy", but would it be alright to update my 5.4.0 to 5.5.0 or do you guys recommend I keep 5.4.0 for kernel/other reasons?
