    I need some support from developers about this question.

    Is possible to make a fake nand backup vía hex coding?

    We will suppose that we have a bunch (3 or more, each from a diferent sysnand fw) of nand backups from a only old3ds and extract the hex code from every nand and analyze his differences to get the sign of the 3ds.

    Then, we have another old 3ds, but this one has a 9.3+ fw and we don't have a backup of this 3ds.

    The question is search the hex code that makes your 3ds nand authentically and merge that code on a 9.2 (or another fw) to make the fake nand backups.

    I'll wait for your answers and opinions :)

    Every 3ds has its own encryption. You would need an astronomical amount of near identical nand backups and thousands of computers working hundreds of years to get the encryption for just one ds unit. It's unrealistic.

    Also modifying any data within the dump breaks the encryption and makes the file useless. You cant just copy and paste pieces. The entire file needs to be untouched from the moment the 3ds created it.

    How can I begin? Jesus christ, it just doesn't work like that. Even a single byte will make drastic changes on hexadecimal values. The 9.3 backup won't be the same thing as a 9.2 backup. You can't simply "HEX HAX" it. You won't get the "signature" out of that, you'll just get the difference in bytes. That won't do anything.

    So...
    Is impossible to make a fake nand with those resourses?

    Impossible. If you view an encrypted file in hex, all you going to see is a mess of encrypted data in hex format. You will never be able to determine what any values correspond to because theyre, well, encrypted.

    Yeahh.... That's not happening until we crack the encryption, which is extremely unlikely will ever happen anytime during the time for 3DS homebrew to even matter.

    But possible if someone get a decrypter/encrypter. Right?

    That's... not how it works at all.
    You'd need Nintendo's encryption key, which I assure you is not easy to find.
    I don't know what kind of encryption is used by the 3DS NAND, but you could easily spend years trying to crack it using a top-of-the-line supercomputer and you'd still have a hard time finding it.

    you would need the impossible to get encryption keys in order to make one ;)

    Not only that, but it's unique to every 3DS, so cracking one wouldn't result in some other one being compromised, too.

    The wii has something similar, it needs both nand backup and keys to make the other nand work on another wii. Yeah still need the keys

    Wonder why the current hombrew and cfw can't get those per console key.

    It's not accessible by normal means. It's built into the chip at manufacturing.

    Nintendo has really stepped up their security game, learning from the Wii. So that's why we can't do it anymore.

    Isn't this the same guy who told us to stop asking for a 9.3+ exploid? Why would you want something like this? Oh, did you update?:P

    This isn't a debate it's an educational slaughter.
