Hardware Why cant i load NAND backup from someone else?

[xmetalheadx]

I have a n3ds with 10.2 on it and i have an gateway card, that i cant use. Why cant i take a NAND backup from someone else to downgrade my console? I mean, if its the same system and the same NAND chip it should be alright, or am i wrong?

You are wrong. I hope this is never possible.

Why?

No. Each console use a different encryption key, each being "burned" in its chip, and as a result only your console can read its NAND.

Why?

(Ninja'd)The encryption keys are different from console to console

Is there a way to read these encryption keys and simply replace them?(I know, it sounds too easy, bit im a noob in this category)

Well, I don't think it is. If it would, I'm pretty sure anyone would have done this by now.

I assume, you have no idea, where those keys might be located, right?

If it's possible, 3ds should stop produce now.

Why?

Less Piracy

don't assume this, assume that....
noob shouldn't doubt anything that pro said is true....

load backup, go ahead.
let's see what's gonna happen

 

[xmetalheadx]

There must be a way to find the encryption keys, for example searching for the differences and simmilarities between 2 10.2 NAND backups from 2 different systems(but those must be the same, for example 2 n3ds's with samsung NAND chip)

No, I don't, but if iirc, one key is unique to the console's chip, one other is created on system creation/reset, and I don't know if there are others, and where they are

Why do i have to stay a noob for ever? I'm currently trying to change that.

You don't have to, but really, one part of going from noob to pro is accepting that if some people found a kernel exploit and dozens of entrypoints in a highly secure system, then they probably tried something anyone can think of. And it probably turned out to be a "bad" idea, since we have NO way to use a NAND backup on another 3DS than its creator.

 

[xmetalheadx]

Alright, then i will give on that idea and stay with sysNAND 10.1... Anyway, thanks for the help ^^

Of course u can change that, but your idea is not thoughtful...

it's like asking the way to load different console's Nintendo3DS folder on a same nand

Well, I'm still a noob and this is my lack of knowledge

 

[how_do_i_do_that]

AES key is encrypted on the NAND and are loaded to the ARM CPU. The key then get decrypted and moved an isolated and seperate section of memory of the CPU unaccessible to the user, it stays there until power is turned off and that point it is erased.

The 3ds uses RSA keys in this case. If you want to understand how the boot order works etc, you can go here:
