    I have 2 3DS.

    O3DS ( 9.4 FW )
    N3DS ( 9.6 FW )


    Only options I currently have are the Sky3DS which has some games and possibly all future games blocked due to AP protection, which it seems on CFW can bypass.

    Yes, I can do homebrew, via browserhax or OooT. ( Homebrew won't allow booting a 3ds game though )

    You can downgrade via hardware ( Gateway or solder a few points with a sd adapter ) but you need to have a previous dump of your NAND from a lower FW.

    Pretty sure all this is correct from what I gathered, what I don't understand is why we can't make a dump of current NAND and patch similar to PS3.

    You can't use NAND dumps from other consoles because they're encrypted with a different key than yours. You also can't downgrade your own NAND dump because you can't decrypt and re-encrypt it.

    Op never said anything about using someone else's nand back up.

    I also told him the reason why you can't use his own backup. Just wanted to give some additional information. To be more specific though: You can't patch your own NAND because you'd have to decrypt it to change anything which can't be done without using an actual 3DS you have kernel access on. Should you somehow be able to decrypt the NAND and patch something you'd still need to sign it so that the 3DS would read it again, which, again, you cannot do without using real hardware. It's like back when people started to figure out how to decrypt savegames but couldn't really make much use of it because you couldn't inject a modified save file back into the 3DS.

    Dont waste time, it doesnt work and its been like that since the debut of 3ds.
    2 solutions, sky3ds or sell and buy firmware 9.2 3ds

    The reason it isn't like the PS3 is with the PS3, you knew the private signing keys.

    Because the encryption keys required to sign 3DS firmware haven't been leaked yet.
    You can't install legit CIAs because there is no public kernel exploit above 9.2.
    However, lots of people have been looking for one so hopefully something gets released.
    The PS3 keys were leaked, so you could sign the PS3 firmware. (As far as I know.)

    It may be a while before a kernel exploit above 9.2 is found but it's not impossible for one to get released.
    It will just take a long time™
    If you want it now, you're gonna have to wait a while..

    Yes, the PS3 keys were leaked thus making it possible to make software that would allow you to decrypt / patch / encrypt.

    So if the keys were actually leaked / found, than it would be possible to patch your NAND and rewrite in theory?

    Well since all of my consoles are 9.0 kexploitable and I only use CFW for backups of my rightfully owned cartridges then hopefully a 9.3+ kexploit is never found. If you were noob enough to update then you have no need for CFW. :)

    Yes. However the keys for the PS3 were found due to a flawed ECSDA implementation. Very unlikely you'll see private keys for any systems going forward.

    It wouldn't surprise me if newbs that updated wouldn't know how to use a CFW. lol

    Some 2/3DS bundles include 9.2> so it's not always because the user updated without doing any research.
    For me if I (for example) got a New 3DS with a firmware above 9.2 I would want to downgrade it so I can pirate and have kernel like on my O3DS.
    This can also be the case with used systems.

    Anyone who updated without doing proper research have nobody to blame but themselves.

    I think what he means is that a newb stupid enough to update wouldn't know how to use a CFW anyway.

    Hmm okay.
    I'm on 9.9 but thats only cos I didn't know about 3DS Homebrew until someone linked to Smea telling everyone to download ironfall.

    Both consoles came into my possession on a higher FW than what could be exploited. I've been around in every scene long enough to know not to update anything when a console comes in to your possession.

    Fair enough.
