I've dumped my NAND via hardware many times, and those dumps didn't match either. Though the dumps are 99% the same, only a few sectors are different. I suspect it is some kind of random seed that gets updated with each boot
Whats then stopping us of downgrading 3ds's that didnt make a backup? Can we make some change to the dump to fit other 3dses? Im sorry i dont know i was just wondering
It's the per console NAND key. The whole NAND FS is encrypted with a per console key, so you can't just grab another console's NAND dump and use it on yours, the same way you can't just edit your NAND because it's encrypted and you likely don't have the key unless you dumped it on an exploitable system (4.5.x or older, unless you have another exploit allowing you to run code in the kernel context on newer systems).
That clears up alot of things thank you!
Well we can only hope that someone can crack the encryption in time and then it might be possible. But i think that we'll have support for 6.3 sooner than this if that will be ever possible

What do you mean?
If you meant an exploit for 6.3 then it could be anytime.
If you meant brute forcing the key then that would take impractically long.
maybe i expressed myself wrong but if the encryption can be broken you could modify the dumps right? and then encrypt them back again using the same algorithm? please correct me if I'm wrong

Only if you can dump the key.

You can't just "crack" the encryption, it's AES based with a 256bits keyset (key + IV). Good luck with that. If you can't dump your per NAND key, you are out of luck, and if you can dump it, you don't really need to downgrade in the first place.
I get that i know its not a walk in the park. But seeing how the 3ds and the whole scene just exploded lately who knows what the future might bring

It's just not possible, not that way at least. It's like insisting that 2+2 = 5; it leads nowhere.
its possible only if hackers worked out the algorithm they used to encrypt the files then you can decrypt all nand if they use the same algorithm
that is basically how the lvl2 in ps3 was hacked they worked out simple algebra encryption method
Don't talk to me about ps3 hacking (for which you seem to know nothing about btw), for lv2 (not lvl2 btw) people had the key dumped straight off lv2ldr, it was a generic key, not a unique per system key.
On 3DS you have a per system NAND key, one that is not the same, (as in different) for every single system, you do not have that key unless you have dumped it before from YOUR system. To dump that key, you either need really, really expensive hardware to perform RAM live dumps AND specific sets of exploits + time attacks, or enough exploits to run your own code with kernel privileges and read it out of your 3DS.
Without the key, you can forget about decrypting your NAND, no matter how well you reversed the encryption algorithm (and by the way, it's been reversed...)
Do you know how many trillion years it would take for anyone to bruteforce that key ? That's with all the computering power available in the world, and it would still work only on one system.
Please don't speak about things you have no clue about.
It all depends on the hackers and what they think pays off and how long it will take them. That would be an ultimate step forward towards unlocking the 3ds
so i assume the 3ds uses a public key to access then ? how does the 3ds know how to access ?
and im only brief on ps3 hacking i have a cfw ps3 and thats about it i know somewhere along the line the ps3 had something that was decrypted with a generic algorithm
