Homebrew Official [Download] Decrypt9 - Open Source Decryption Tools (WIP)

[key1340]

Test version is coming later today, with most of the important functionality already working. Stay tuned...

In the meantime, I have a question to A9LH users running Decrypt9WIP. ..I understand that, if run from SysNAND A9LH, most decryption related stuff will not work. Now, if you start Decrypt9WIP from SysNAND A9LH, and, without running any other features first, try to dump the SysNAND CTRNAND (I know, it will not work), what is the exact output in the debug console? A screenshot, photo or the relevant part of the Decrypt9.log would help a lot.

It would help even more if you repeated the process with Decrypt9WIP running via some other means (A9LH EmuNAND, f.e.) and also provide the output.

Decrypt9 works fine if you load 9.2 a9lh sysnand or emunand with the 3dsx.

It's when you load Decrypt9 from an arm9loaderhax.bin that it can't decrypt anything.

Of course you can't because no keys are loaded yet...

I know that.

It seems that @d0k3 thought it didn't work even in sysnand.

CTRNAND isn't set at all. And IIRC, the CTRNAND keys aren't set either.

There's another method of getting the IV (also called NAND CTR), which might work. If the keys are not set, though, it isn't even worth trying.

I know that.

I knew that, just didn't know the name of th arm9loaderhax binary .

Question is: is it even worth it getting stuff to work on arm9loaderhax.bin? If you can't load 3DSX or CIA, your first concern, even with A9LH, should be restoring your SysNAND to working order, not fooling around with some other stuff. I might do a dumbed down / simplified SysNAND restorer later. Maybe hold a button to load it, otherwise move on to CFW? Will think about that later.

I imagine that it's mainly people who swapped over to sysnand who want full crypto abilities in D9 at boot. That way they don't need to have a separate 9.2 emunand to boot into whenever they want to fully utilize D9. Though I guess even people on a more traditional 9.2 sysnand/updated emunand setup might like it too just because getting into D9 at boot is hella fast.

Ultimately I would think that getting full crypto for D9 at boot would be a nice-to-have and not a need-to-have. Not utterly necessary but it would be cool to see how far the limits of things can be pushed.

Well, I think that if we can't access decrypted CTRNAND, we can't get GodMode9 to work with arm9loaderhax... Am I wrong ?
I would love to have access to my CTRNAND, so I won't have to reflash everything and I could unbrick easily (because no FIRM/TWL/whatever partition restoring)

Sizewise (and that means the time requirement, too), TWL/FIRM etc... don't matter much. And yup, we need the keys for TWL and CTRNAND set and we need the NAND CTR for GodMode9 to work on arm9loaderhax.

There needs to be a feature to abort a dump. If I accidentally click the wrong thing I don't want to wait a half hour to use my system again.

Changelog:
Battery Removal - Take out the battery to abort any function

Thank you.
I wasn't sure if behind the scene stuff would write to whatever I'm dumping for whatever reason and corrupt it.
Even if you were joking, I already took it out. It's fine.

Dumping will never corrupt anything except the thing you dump nand or something, then you just delete that file frome the SD.

Thinking about that, but aborting stuff might be not as simple as you think, cause for any buttons to be responsive I'd need small buffers, which would lead to slow copying.

And yes, taking out the battery or a force shutdown is perfectly okay. Not if your injecting anything to the NAND, though, but that should be clear.

"Accidentally took out the battery while restoring NAND.bin"
How do I fix this without a hardmod? My system won't turn on but is there any software based programs I can use to revive it?
It's a joke btw

OOh also it will reset your 3DS clock.

Does restoring emunand to sysnand delete everything at once?

--------------------- MERGED ---------------------------

My emunand is being written over my 2.1 sysnand and wonder when if at all I can abort it.
By the way, I used the browser exploit to launch Decrypt9 and the screen went black after saying to restore my nand.

I wonder if that is a joke again. You don't have a hardmod? You need to wait, otherwise you'll be bricked!

 

[Halvorsen]

No, I'm fine. Haha, my screen is bad so I thought I was restoring to emunand.
It's just a little tedious. xD

 

[d0k3]

Question to everyone, a while ago someone put together the Decrypt9WIP CIA.... Now I don't find it anymore, and the forum search function doesn't accept three letter words, oh well... Can anyone point me to the correct post?

So you restored your NAND (to get back to 9.2) and now the screen is black? If I understand the situation correctly, you need to delete the extdata that's currently on the SD card and restore the files that you backed up at the beginning of the guide.

No, I am restor(ing?) by 10.5 emunand to sysnand but when it started the screens went black. I don't know if it finished or halted.
