Homebrew Smealum, Creator of Portal DS/Aperture Science, has hacked the 3DS

All of my games are digital, though. Anyways, are you sure formatting brings the firmware back to the first version? I'm fairly sure it doesn't.

That's not what he implied - what he said was that formatting your system will make the update message go away and not going online will keep it away for good.

Nothing new here at all basically, then? Same ds profile mset exploit. What's the novelty exactly?

I'm amazed that now 3DS downgrader is available yet. That means that either there's lack of documentation and/or knowledge of the NAND (is that the correct type of chip storing the 3DS firmware?) or lack of interest by coders to do so. Possibly a lack of interest could be all encompassing of a high disregard for computer piracy by the homebrew scene which is very understandable for obvious reasons.

Conversely, if there were devices that were only purposed for homebrewn unsigned code or such then we would be seeing a lot of interesting things happening now. Personally I'm not at all interested in pirating 3DS games which is why I do not own a Gateway 3ds. I don't feel that purchasing the games was a waste of money and plus there's tons of good deals on factory sealed games out there.

No, but you were asking how to get rid of the update message, and formatting removes the downloaded update (or you could remove it manually from the SD, it's in /extdata/ or something).

Just the NAND is encrypted and per-3DS, so you can't use somebody else's dump. You can downgrade if you dumped yourself on an earlier firmware.

Or if we can get keys with help of known kernel exploit.

You can't. Keys never leave the chip.

her u have them... no kidding IMO its easier to break a diamond with your bare hands then hacking the nintendo private key

Haha, yeah, exactly.

NAND encryption is different from executable signing. Asymmetric key encryption is too slow for nand encryption. It's likely symmetric key AES.
I believe there is a Wii tool for making clean NAND with keys: http://wiibrew.org/wiki/Ohneschwanzenegger

 

[Rydian]

Ah, thought you did indeed mean the executable/signature stuff (like most people do when suggesting that).

that's pretty useful. I guess you could dump your nand, go on the shop and get new goodies, then downgrade. Looks like a very easy mod and I guess the software is easy to find to dump with. Looks like it is a good idea to make a backup to keep.

Well, as far as I know, the licenses are kept in the 3DS's internal storage, not the SD, so when you downgrade you're removing the license info and the stuff you downloaded from the eshop won't run.

but what if you backup nand on 4.5 ,update to 6.xx ,buy from eshop ,downgrade back to 4.5 ,then go back up to 6.xx ?will eshop games still work ,or they only dont work when on lower fw?

I'm not entirely sure, I don't think anybody's tried that since the 3DS eshop is tied to the system and not an account, it might not remember your purchase and you may have wasted the money and need to rebuy it again.

Because nobody's going to call Nintendo and be all "Yeah I bought a game and then I was voiding the warranty by flashing the NAND and I lost the license info can you reactivate it for me?"

Downgrading removes all tickets of the contents in NAND, which doesn't exist at the time, at which the dump was made. The 3DS deletes all titles without a genuine ticket!

And btw. I read everywhere "custom firmware". This should be clear: It's not possible without a bootrom exploit, because of signature checking. No one knows, if NAND emulation is possible in the future. It should be stickyed to avoid these dreamers.

No chance of a soft reboot into hacked firmware/dash/loader/kernel/menu?

well you wouldnt have to call nintendo to find out, someone could just DL the cheapest eshop title and then experiment and see what happens

I just downloaded MK7 from the eshop and flashed back to 4.4 then back to 6.3 and MK 7 is still there. Of course the game didn't show up under 4.5 but it wasn't deleted from the sd card.
