Homebrew How to get saves from dead 3DS?

Deleted User · Mar 20, 2019

My old Nintendo 3DS recently died from age, and I've been a little upset. I never got to finish Phoenix Wright: Ace Attorney: Spirit of Justice. I got it working on Citra, but I'm missing my save data. I searched up how to transfer saves, but that requires the Checkpoint CIA to be installed onto my 3DS. My 3DS currently does not turn on.

Is there anything I can do to get the save data?

Thank you!

I thought that saves were stored on the SD card, I guess not.

They are on the sd card - however it's encrypted

I think OP is gonna have to decrypt his sd card somehow

How did it die, maybe it can be fixed

Non-GC saves are stored there but they're all encrypted if I remember correctly.

I'm not sure if there's any standalone tool that can decrypt them.

Edit: Ninja'd by the blue blur

I mean, I assumed that transferring data from one 3DS to another was simple, according to the Nintendo guide anyway

https://en-americas-support.nintend...ansfer-data-between-sd-cards-or-microsd-cards

Guess I was wrong. Oh well.

If you have a NAND backup + OTP from the console or movable.sed from it, you can decrypt the 3DS's SD Card content. Or if you know of another console that has it added as a friend and has custom firmware, or the owner is willing to set it up. Otherwise, the save files are likely lost forever.

I doubt it can. The screen won't turn on and no sound comes out of the 3DS. The power light turns on, but nothing (not even the splash screen) pops up. I searched it up and I don't think there are any quick solutions. I could be wrong, however.

That guide is between sd cards on one system

between systems is not possible because the sd cards are encrypted on a per console basis

So the power light turns on. Does it stay on, or does it make a noise and turn back off?

Also, were you playing the cia or from a game cart?

Well that's a real bitch to deal with.

If you have your

Friend Code: #### - #### - #### (or know of a friend who has it)
<ID0> folder

you can brute force your movable.sed with

Decrypt the saves using fuse-3ds and 3ds-save-tool guide.

I was playing from a CIA.

No noise comes on. And it doesn't turn off by itself. I have to hold the power button for a very long time before it shuts back off. It charges alright too, it just doesn't do anything.

Wow! I'm going to check with my friends to see if they have my friend code.

Make sure you check if the hardware is actually dead, since all you've said so far is "it's not turning on". Replace boot.firm on the SD card (assuming boot9strap or related exploit, if you are not using this please specify), hold buttons like SELECT at boot, and see if anything changes. It would also help if you list the files at the root of the SD card.

Just tried replacing it. I downloaded the latest version, renamed it to boot.firm, and replaced it. Now, the 3DS' light simply turns off after a couple of milliseconds of being on. I've tried holding start and select, but it didn't change anything.

Here are most of the files on the root:

There are some other minor files at the bottom. Many of the files are old as well.

To check if you have boot9strap custom firmware, rename SafeB9SInstaller.firm as boot.firm and put it on card root. If it boots, do updating B9S with SafeB9SInstaller in place. After the update, you replace boot.firm with Luma3DS v9.1 and continue with everything else.

Replace boot.firm with the firm from https://github.com/d0k3/GodMode9/releases (and rename it to boot.firm) and then try turning your console on again. Could be fixable, if changing the boot.firm makes it go on then off (that means the boot.firm is incompatible with your B9S installation).

If that results in GodMode9 appearing when you start up your console, do this: https://3ds.guide/ctrtransfer

If it doesn't help, use @TurdPooCharger 's script for GodMode9 but that may destroy your saves while saving your console.

Edit: Or also update your B9S installation as he suggests above

Doesn't your 3DS have to be functional for that, i.e. so that your lfcs can be transferred to another 3DS? That is, the first step of the brute force process is "Add the bot to your 3ds friend list".

Since you have cfw already, you probably already have a moveable.sed somewhere and don't need to contact your friends. Depending on what version of gm9 you've been using, you might have essential.exefs in gm9/out, and you can extract it from there using fuse-3DS. Or you might be able to get it from a NAND backup.

Otherwise, as suggested by @ihaveamac , not only do you need a 3DS with your Friend Code in its friends list, but you'll need to run homebrew on that 3DS. (Fortunately you can do it with just *hax; you don't have to make any persistent changes.)

I think the 12-digit Friend Code is somehow related to the first half of the KeyY. However, I could never figure out the mathematical formula how that friend code = first half. The second half is found through brute forcing using the <ID0> folder as the target answer. Once you have that exact 0x10 bytes KeyY, you can use any 3DS system with GodMode9 or on desktop with fuse-3ds to decrypt your stuff.

Sorry for the late reply.

So, everything seems to be working fine now! The menu works and everything. The only problem is that most of my games are missing.

I did everything the guide told me to do except the Finalizing Setup. Are those games lost forever?

System Settings → Data Management → Nintendo 3DS → Software

Missing tickets → faketik

***

if tickets are not missing but <ID0> folder matches with movable.sed KeyY, (ie, corrupted title.db and import.db):

I made a NAND backup awhile back, now had to recover, missing games.
