yes every download needs a valid ticket to be usable, even if its encrypted for the correct console.......think of how eshop downloads show in sysnand but are unusable.....they are encrypted correctly, so they show up, but the license to use them is missing from the nand......in this situation it would be stored in the 9.x nand

Ahh! Now I get. Even if I have a 8.1 emuNAND based on my own console, the "license" isn't there.

Thx for the explanation.

Now I have another discussion still in the same topic the OP posted.

What if I try to use the discussed method some posts below, which works flawlessly, but instead of using a ROM from the US region I try to use a ROM from EUR or JP?
Assuming the game even loads, because as far as I understood, the GW run the enuNAND without any FW modification and for that reason the game should not even load, will the method still work?
And more, will it be possible for my console end up with another region NAND?

doesn't work :lol:

just says something along the lines of "this software cannot be used"
 
I have a better question:

Now that we have tools from 3DS ctr decryptor void that allows us to decrypt and re-encrypt ROMs, including the sections containing the firmware updates, would it be possible to use this feature to install custom .cia files inserted using the recent encryption tools?

guys. wanna ask similar question. i have gateway which can run mario kart and kirby without a problem even without emunand. however my clone card failed to load mario kart and freeze in title menu while playing kirby. i guess i need to update emunand using this method?.

MIND = BLOWN

now if only makerom allowed repacking multiple partitions... we're gonna have to edit things manually to attempt this
 
The problem is that it has 7.x encryption. Currently very few people know how to decrypt it and it probably won't be revealed anytime soon.

What if you just use an older rom with a previous firmware update?

That is exactly what I had in mind! As for 7.x (and now 9.x) encryption, who says that decrypting newer ROMs is the only way?

If it is possible to install custom .cia files this way (such as firmware ones modified to enable full kernel mode), then it should make it possible to decrypt and unpack NAND dumps. Once that is possible, then we can extract the .cia files for the latest firmwares (received from SpotPass, but not installed) directly from the NAND dumps, modify them, and install them!

We can then use the encryption key to decrypt and extract the data from the latest firmware, find the file(s) containing whatever new keys Nintendo throws our way, and use them to make the current tools compatible with any new keys.

The process can then be repeated with each new firmware update!

Wouldn't really help us at this moment, as no game (nor ROM) has released with the 9.0 firmware update, and I imagine it would take quite a while to figure out how to convert e-shop downloaded firmware updates to be attachable to ROM code.

An interesting thought none the less, I hope somebody follows through with this or something similar.

yeah,
1. pick format emunand from the gateway menu
2. boot up emunand, go to system settings and make sure you set it up correctly, it will say GW3D, in front of the system version (if it says Ver. 4.x go back and actually do step 1)
3. shutdown the console
4. boot back up into emunand and hold UP when triggering the DS profile exploit, this time DO NOT enter system settings press select and choose a game with the required FW version from your region, and do the prompted update

Bonus step between steps 2 and 3, you can move some stuff around on the homescreen and use that as a visual indicator as to which nand your in, like having a folder named "Emu" on emunand and "Sys" on system nand

you cant use a EU rom to update a US console etc, and you cant use super trimmed roms as they have the update partition removed

worked :D
thanks man

D-pad Up disable update spoofing? I didn't know that, and never saw it explained anywhere before.

Do you know which firmware added this option? I'll add it to wiki.

I tried it on the latest gateway omega and it worked :)
Updated using Super Smash bros rom as I dont have that game at the moment lol.

i think it was added in 2.2....i think XD

but yeah it never got a PSA, either someone found it by accident or it was told to someone by gateway support email iirc

Adding to my previous post, you might need a custom header.
I used my own header and updating worked.

Someone correct me if I am wrong :)
