Hacking So without getting flamed to hell for this. Regarding why the 3ds isn't kernel haxed on 11.0

[bbcali89]

TITLE EDIT: SHOULD BE why isn't there a downgrade available for 11.0

Okay, so I understand that the homebrew scene is very slim and the only way to downgrade a 11.0

is:

dsi save exploit.

Still I'm curious:


What is holding back a downgrade for 11.0?

Has svchax and memchunk in general been patched to unfixable status?

If the case is anyone developing something new for it?

I see often homebrew userland hax coming out, newest I believe is stickerhax.

Yet, a kernel hax is only on 9.2 and the downgrade only goes up to 10.7 I believe?

I guess I'm asking why is this? Can anyone with recent information come forth and help my confused mind lol.

I guess it's because nobody's found anything that can be exploited yet, or if they have then they haven't released it.

So it's as I thought, svchax and memchunkhax are completely patched now?

The problem is the arm9, which now verify with a hard-coded list the title version of the titles you want to install.

okay that better explains it. So basically nintendo didn't patch it as much as hard code minimum firm versions, effectively making downgrading impossible. Atleast until we can somehow exploit those files. Correct? then in THEORY svchax would be usable again?


So then i'm kind of curious how does the DSi exploit work?
Does that mod the needed filed in the hard code to allow a downgrade to happen?

We need an arm9 exploit, because it's the arm9 (process9) that verify the title version. So, even with a kernel 11 exploit (svchax), it's useless.

so basically dsi save exploit is a arm9 exploit?

Nope, but it's enough to write to the nand...

 

[Swiftloke]

No. The dsi exploit takes over dsi mode, which because Nintendo was lazy gives full access to the NAND. Then we can do the hardmod downgrade, because we've got NAND access.

OK, that's true, you have not really an arm9 access, but only access to the nand, which is enough to downgrade on the PC the native firm, to be able to downgrade the 3DS.
Sorry....

wait this is incorrect is it not?
You can downgrade without a hard mod.
You switch the console (system transfer) moving the dsi with the haxed save over to the new console. And then downgrading like that right?

This is correct.

The hardmod is not needed because you can dump the nand with the dsiware exploit. Then, on the PC, you downgrade the NATIVE_FIRM, and then you reinject the nand on the 3ds. Then, you can downgrade!

Seems like a complicated process. So i'm downgrading an extracted NAND (title cias I assume, essentially replacing cia files) repacking and restoring that nand to that 3ds? using dsi exploit?

How would this work though? isn't your NAND tied to your console?

I think you've misunderstood. The dsiware exploit uses the same vulnerability that the hardmod downgrade does. It's just a different way to dump the NAND.

Okay gotcha. I think i got it now. always cool to learn new things lol

Not completely true, we still don't have an arm11 exploit to even install the files to start with (otherwise we'd be able to install legit cia games on 11.0, and only be prevented from installing the system titles by the min version list).

You can just make something happen because people want it to happen. We have some of the smartest minds in the 3DS hacking community behind this and they still haven't accomplished finding another exploit, yet.
Just give them time though and they will find something.

I'm aware this was more of a WHY topic. a development of sorts and more of a general question about why 3ds development has halted pretty much.

I assume in part because of the new vita hack

Is there anything you can add that hasn't already been suggested? I am not trying to be rude, but there's reason it hasn't been made yet.
