Homebrew 3DS Recovery Tool - A tool for backing up/restoring/wiping sensitive data.

[Deleted User]

Alright now that I'm getting a lot of requests on the name, I guess I'll change this to '3DS Recovery Tool' instead.

(Even though that other 3dstool thing isn't even a 3DS app)

On the 3dshacks reddit there were some people who thought of 3DSensitive or something

I noticed and I didn't like it so I'll just stick with this. 'Sensitive' is a broad term and could pertain to anything. Just the name 'Recovery Tool' should give the user at least somewhat of an idea on what the app is about.

Anyways let's leave the whole name changing thing behind now please.

thanks for this @Joel16, im the guy from reddit who had problems with qr code, anyway grabbed the .cia, and as expected great little useful app, wiping parental controls is great feature, why everyone getting hung up on what to rename it idk, but im happy as is, thanks again.

edit: @Joel16 when trying the back up local friend seed, im getting failed with err 0xc8804478, everything else backs up fine just this, is it something im doing wrong?, ive tried with sm and fs patched and unpatched if that makes a difference using .cia of tool

Sorry, when I liked your post your edit wasn't there.
Can you confirm by going to ctrnand/rw/sys/ on FBI or 3DShell and confirm there's a LocalFriendCodeSeed_B file?
Because err C8804478 means Title/object not found? (fs) (120).

hi @Joel16 right thats probably the problem mine says localfriendcodeseed A, im clueless regarding friend seeds, i guessing mines private and b seeds are public?, im probably wrong, either way, if you have the time could you explain, and thanks for the reply

Ah just found out that some consoles have LocalFriendCodeSeed_A instead of B, and some have SecureInfo_B instead of SecureInfo_A.
Also there's a SecureInfo_C (according to Aiko), looks like I'm going to have to update this tool to account for all changes. Probably by tonight.

you're like the king of 3DS utility at this point with all these applications, thanks Joel16

anyway, quick question. when i backup my locakfriendcodeseed i noticed that its in /3ds/etc/blah/. hypothetically, can i backup my seed from my older 3ds and then bring that seed to my newer 2ds xl model and 'restore' it to essentially swap out the 2ds's seed?

The thing is the 'restore' function doesn't inject any LFCS. All it does is deletes the LFCS in nand, then uses the data stored in memory to re-create the LCFS file, basically restoring it to its 'factory state'. If you want to inject stuff from one console to another you'll have to use decrypt9 or godmode9.

Version 1.2 is up.

• Added option to dump original LocalFriendCodeSeed_X from memory. This option can be found under the misc sub-menu. The dump is stored in /3ds/data/3dstool/dums/LocalFriendCodeSeed. (Note this is different from backing up your current LFCS, as this dumps the one that is located in memory, not in NAND.)

Just for clarification did you get banned during the Pokemon sun/moon ban-wave? Well whatever it is you got banned for, seems like it was temporary. Also you could've just used the "Restore Original LocalFriendCodeSeed" option and it would've restored the original one for you without having to dump anything .

Anyways, I decided on cleaning this up a bit and put up a new release.

3DS Recovery Tool v1.3

• Major changes with file handling. Cleaned it up so that it can properly access both archives. (i.e smdc and nand archives)
• Used more explicit names for options.
• Added option to restore LocalFriendCodeSeed_X and SecureInfo_X from backup. This option restores the backups you made within the app.
• Fixed dark theme mode being unreachable since the previous version (v1.2).

Works great but it would be nice to have an option to display both the original and current LocalFriendCodeSeed either in this app or in 3dsident (or both).

I'll probably get that done for 3DSident.

Looks like I spoke too soon, the restore original seed function isn't working. After using it my seed remains the same as before and when I check /rw/sys/ I see there is a localfriendcodeseed_B.invalid and a localfriendcodeseed_A rather than just localfriendcodeseed_B which is what is normally there.

What option did you use exactly? "Restore original LocalFriendCodeSeed", because this is a single function call provided by Nintendo.
