    Do not update past 5.2.0/5.3.0 if you can help it. Unknown if kernel exploit is fixed.
    Currently, we have a userspace exploit that can be compiled and run via the Internet Browser. It currently works on versions 4.0.0 to 5.1.0. This isn't very useful at all for anyone who isn't a developer. All it allows is basic access to reading and writing certain parts of memory (assuming it isn't protected) and basic library functions. We can't access the filesystem or likewise install or change anything on it. You have to run the exploit every time you want to do something. You can find the exploit here.

    Frequently Asked Questions
    Q: How do I install the Homebrew Channel?
    A: Wrong place to be looking, you're thinking of the sandboxed vWii (virtual Wii). For more info go here and here.

    Q: What is this?
    A: As mentioned before, it's an exploit that uses a bug in the (very old) version of WebKit that Nintendo is using for the Internet Browser.

    Q: Why doesn't it work on anything after 5.1.0?
    A: We only ever found and developed one bug, and (I assume) Nintendo caught wind of the bug and patched it in 5.1.1. We would have to find another one that would lead to being able to manipulate the memory to be able to do anything more.

    Q: What's the latest version the exploit works on?
    A: See above answer, it works on 4.0.0 through 5.1.0, and there are 3 separate versions for 4.0.X 4.1.0 and 5.X. It was first made for 4.1.0 and then later back-ported to 4.0.X, since some addresses had changed. Later, the update that added the Quick Boot Menu (5.0.0) changed the code structure enough that we had to blindly find our addresses again and rebuild the ROP chain to get code execution again.

    Q: I don't want to miss out on potential homebrew, how should I update to a safe version?
    A: The recommended way is to use the disc version of Mario Kart 8 which comes with 4.1.0. Make sure your Wii U can't access the internet and then run the game and have it update with the data on the disc.

    Q: I want to update to the latest version but I don't want to miss out, am I safe in doing so?
    A: NO. Do not update past 5.3.0 if you can help it.

    Q: I haven't heard anything in a while, when can we expect to see progress?
    A: Everybody who has the ability to work on the kernel exploit or find and exploit a new bug is busy with school, so progress has been slow. Nothing has been cancelled, only that nobody's had any time to work on it. As for when you might hear something, probably sometime in December, since most of us get "Winter Break" to transition between semesters.

    Q: Since the exploit is broken in the latest version, what are you going to do now?
    A: Finish it, of course. Just because it doesn't work on the latest version doesn't mean we're going to give up. It's still useful and usable on quite a few versions. We finish what we start.

    I thought that was just for the eShop, I believe you need to block a range of actual IP addresses...?

    Nah, like I've said before, nus is nintendo's update service, it has nothing to do with the eShop, AFAIK that IP block is all of the IPs that that URL can use.

    If it's anything like the Wii Shop Channel, then all the digital titles are also stored on NUS.

    but if I remember correctly, someone actually found an url or ip recently, that prevents the wiiu from finding any updates..... the beforementioned url only prevents the download, but what he found actually prevented the update check... was just recently either in 5.0 update tread or 4.1 exploit leak or the hacking discussion thread... lol cant remember where, but it was a couple of days ago

    I don't know how to block URLs on my router, so I'll just turn off Standby download for now.

    Hi!, A little question, It would be possible to make a offline exploit in the future? Some user tell me I need to update my router with a firmware to block all the Nintendo adresses to make the Wii U don't update, but I've bricked it, so I don't have online for the web browser exploit, are some dev planning to do a non-internet exploit?

    Yeah, I know they don't have the kernel or all system access, but I'm only asking, something similar like BannerBomb with Wii, but they need to hack the Wii U Filesystem format for that...

    There aren't really any other entry points besides the browser. The browser is the only component of the system which is based on open-source code, giving us a great advantage in finding bugs. It's also one of the only places where we can feed untrusted input, since external storage is now encrypted. There is no way to "hack" it, since storage is encrypted with a per-console key. A game-based exploit is a possibility, if there are some games that access external storage without encryption, but it's highly unlikely that such a thing will surface.

    Sorry, but can anyone help me do this on dd-wrt? I already tried blocking addresses and IPs before and it didn't work.
