Hardware Would a N3DS nand dump be wise?

[atkfromabove]

I am getting the US N3DS this Friday and wanted to know if hard wire dumping the NAND right when I get it would be beneficial? I am planning on updating to the 9.5 firmware for SKY3DS but want to have a backup of my original NAND in case later on down the road there is a exploit (GW) on the earlier firmware found.

Would I be able to downgrade and flash back the original NAND if this happens?

Also to save some time tracing the points myself is there a pinout image for the N3DS NAND?

If it comes with 9.2, then I believe you would be able to use Gateway to backup your sysnand.

GW does NOT work on the N3DS yet.

Ha I was wanting to save myself from buying the gateway preemptively just incase support takes a while since spending $90 on Sky was not cheap. I am comfortable doing a hardware dump for the NAND if possible for the N3DS.

Edit: To clarify I want to dump the NAND without the use of Gateway. I want to dump it with a hard wire install.

Guess it would be a good idea to back it up, but also wouldn't rush updating the n3ds afterwards, I don't think I've seen anything about successful nand restore on n3ds yet.

Is there any type of pinout image for the N3DS NAND? I tried searching for it but couldn't find anything for the N3DS just the regular 3DS.

the mobo is missing a pinout so dumping nand is not possible right now.

Really? That sucks but thanks for the info that helps my decision. Are there any N3DS teardown threads that have internal technical information that you know about? I am excited to see the N3DS internals.

The pins are most likely there, we just don't know them yet. Various members of this forum have posted pictures or their consoles boards, e.g.

The NAND data is encrypted with a per 3ds key, you need to decrypt the nand (either stream its content or get its xorpad) before it becomes of any use, good luck doing that without running your own code on the device.

We don't need unencrypted NAND. A neat side-effect of having access to the NAND chips is that you can write back your own backup anytime you want. With hw NAND access we've been switching between FW versions long before Gateway made downgrading possible.

Well that's good news I think I'll try and find a way to dump it for a backup if I need one in the future! Only a couple more days.

It looks like there has been others looking into the pin-out already. I found this post in one of the thread links posted by enarky:

They are saying that the NAND is 4GB this time that's pretty big to dump! Thanks for all the links to the threads!

I wouldn't mess around with NAND dumps and what not until the missing pin is found for doing NAND mods. Currently if you brick your n3DS, you are completely ***ked, because the pin out for the missing solder point hasn't been found yet, so you can't even do a NAND mod yet.

So this seems to work for me, check here for some more info on the N3DS NAND dump

Wow thanks! That is exactly what I was looking for! This should help me a ton.

I'm gonna try to hook up my nand-x and dump the NAND once my N3DS arrives so that I have a stock NAND backup in case Gateway has a release for the earlier firmwares!
