Hacking Gateway Downgrading

[spodermen]

install the old exploit with the new launcher and the old blue card is working.

Hopefully someone will find a way to downgrade without a gateway to use CIA cfw (which allows piracy right?)

you don't need a Gateway to downgrade your 3DS. I did it and it worked well

 

[zwang1208]

it worked fine for me!

I use R4 card to replace blue card. it works

When in EMUNAND mode (on 9.4 FW) does anyone know if you can do a system transfers or will this not work in EMUNAND mode?

 

[poisonousj]

if you're someone like I was who was on 9.2 w/ game saves and eshop content you didnt want to lose, do this.
1. back up your SD card to your PC. afterwards put sd card back in the 3ds
2. boot gateway and Format Emunand. this will reformat the sd card
3. take out sd card. copy back up from PC back over to the sd card. overwrite any same-name files
4. with the sd card still out of your 3DS, reformat the 3DS and go through the initial start up steps till you're back at the dashboard. this will unlink your account.
5. turn off, put sd card back in.
6. turn on, note you have empty reformated dashboard (this is your sysnand)
7. boot into gateway mode, note you have your 'old' dashboard with all your old eshop games and stuff (this is the emunand)

you can then boot back to the reformated clean sysnand dashboard, perform the firmware downgrade from 9.2 to 4.2 and then when you boot back into Gateway mode either with the web browser exploit or the blue card, you'll be back to emunand with all your eshop content.

I'm no expert at 3DS, Gateway, or writing guides but these are the steps I took and I can still launch my eshop copy of Phoenix Wright and load my old 9.2 gamesave when I boot into Gateway mode. I recommend Googling and finding better steps then what I wrote, but just know that it is possible!

EDIT: i'm running into problems getting into the eshop with emunand! so might want to hold off... although my biggest concern was losing my saves...will update once I figure out what's going on.

Downgrade from 9.2.0-20E to 4.5.0-8E was successfully!

Spoiler

Now I want to know, is it possible to restore the SysNAND without the red Cart?

if yes, how?

Would be cool if I can install a CFW to the 3DS. If you know how it works, tell me

Yes, I have restored my Nand backup without the red cart and to do this, you have to enter into downgrade menu holding UP button

Just joined to help out and confirm that I was able to downgrade my Pokemon X/Y 3DS XL to 4.2 without any issues. I still even have all my eShop games and stuff installed.

It already possible, gw card is not needed for the dg, just the launcher.dat and the correct dg file.

After doing this can you go into eshop on emunand?

Yes and no. You can downgrade with the current exploit without the red card, but you can't install .cia unless you either have the red card or someone confirms CFW working on a downgraded console (and, as far as I can tell, the only current CFWs require the red card to install, anyway).

After doing this can you go into eshop on emunand?

Should work, yeah. In fact, you can use your blue card (only once, until you decide to run a DS/GBA mode game) instead of relying on WiFi to run the exploit.

Thanks so much! I also have a ton of legitly bought eshop games, now i can downgrade as ease

I guess the two key points are:

(1) Downgrading does not delete stuff from emunand

(2) If you have stuff on sysnand you want to keep, first move them to emunand by unlinking. Then by (1) you can downgrade without losing stuff

No you don't understand. If you separate sysnand and emunand you have to enter again NNID info on sysnand in order to be able to go into eshop on emunand. If you downgrade to 4.5 where there is no NNID how does this affect emunand NNID and the ability to go into the eshop on emunand?

 

[Xzi]

That's what needs testing - is the downgrade solid and genuine - or is it achieved by some software tricks to fool the system into thinking it's an early firmware? One good test of that would be to do an upgrade to an intermediate sysnand firmware (below 9.2) using a genuine cartridge, and not in emunand.

I don't even.

Do you know what the phrase "grasping at straws" means? Why is it so unbelievable for you that this is a feature of Gateway when there are so many other, more impressive features included already?

Once you've downgraded, the hard/risky part is over. Upgrading firmware is easy.

 

[Intronaut]

Its possible to install ds exploit through DSTWO?. I will get my GW in march, but I wanna downgrade now

 

[Adeka]

Yeah it should be

 

[Xzi]

Others in this thread have stated no, using a DSTWO will not work for installing the blue card exploit. Not sure if that's only when using this downgrade, or what.

Though, he does have a point. Gateway is known for the dangerous launcher.dat bricking, which may or may not have been removed by now, and Gateway hosting the raw 4.2 downgrade files is likely illegal anyway, so there must have been a series of file modifications to make it happen, or they're actually hosting the official updates on their site.

No you don't understand. If you separate sysnand and emunand you have to enter again NNID info on sysnand in order to be able to go into eshop on emunand. If you downgrade to 4.5 where there is no NNID how does this affect emunand NNID and the ability to go into the eshop on emunand?

I see. I'll check as soon as I downgrade and post results.

EDIT: On EmuNAND on this 4.2U (From 9.2U, this is the Zelda XL), it remembered my NNID, and I connected just fine. My download history and money are still there, too!

HOWEVER, I am getting an update nag, and I bet if I format this 4.2U, it'll forget my NNID. Dang.

Zelda 3DS XL originally on 6.1 and upgraded to 9.2 successfully brought back to 4.5E. Make sure to check the checksums after you copied the files on SD, and to keep it connected to AC just in case.
