    Hi. First off, I'd like to say that I will never be involved in any business involving 3DS hacking. I do this for fun. I enjoy reversing and finding exploits on consoles, although, this is the first exploit I have found that proves useful.

    To those who have extracted the data from the patch (decrypting is the hard part, but some people already know how to do this) - you may notice a function that will override signature checks by calling it with a key stored in the decrypted package. I guess Nintendo has a whitelist for certain keys? I haven't yet looked into the signature checking function yet but could not find the decrypted key anywhere in the 3DS RAM, so it's obviously somewhat encrypted. The decrypted key is 8 bytes long.

    This allows us to sign our own packages using the same key and override function. I already have a 3D "Hello world" application running! There is no good reason I can think of for Nintendo doing this, I believe that they used it for eShop debugging and forgot to remove it. A simple mistake. But be quick to look because I am sure they will remove it in a new firmware sooner or later.

    Sorry for any bad English :)

    Wut?

    If it's real does it still works with the yesterday update (it's maybe why they released such a small update that fast, they discovered their mistake) ?

    Video?

    Sorry but we get people claiming they hacked the 3ds every week.
    If you want people to take you seriously can you please upload some evidence?

    I think he thinks he knows what he is doing...
    The "hello world" app you have running.... is running in DSi mode. This is not 3DS hack.

    You also say the keys are encrypted and/or you still do not have them. So you still can't hack anything.
    "could not find the decrypted key anywhere in the 3DS RAM, so it's obviously somewhat encrypted. The decrypted key is 8 bytes long"



    "This allows us to sign our own packages using the same key and override function. I already have a 3D "Hello world" application running! There is no good reason I can think of for Nintendo doing this, I believe that they used it for eShop debugging and forgot to remove it."

    How does this allow you to do anything?

    First post too.

    Can you post proof?

    Also I added an "a" in hex editor in the app file, and the nintendo 3ds screen just kept going on and on, so I went to the home menu and it said error and told me to turn off the 3ds.

    Besides the obvious BS here, I would like to point out that is no possible way the key size is only 8 bytes (64 bits). That would make the 3DS ridiculously insecure and open to simple bruteforcing.

    How cute and original.
    I love the "I have no intent to hack the 3ds, but here's how I did it."

    If you don't post proof (i.e. videos or pictures), this thread will burn to the ground.
