3DS Recovery Tool is a homebrew application for dumping, restoring, and backing-up unique data on the Nintendo 3DS.

It's somewhat similar to a recovery menu, and allows you to format/wipe various files. Also worth mentioning this is an expansion of the author's previous tool, RestoreLFCS.

Features

  • Back up LocalFriendCodeSeed, SecureInfo, movable.sed, HWCAL0.dat and HWCAL1.dat.
  • Dump original LocalFriendCodeSeed from data (not the same as copying the seed from nand).
  • Dump original SecureInfo from data (different from copying the SecureInfo from nand).
  • Restore LocalFriendCodeSeed and SecureInfo from memory.
  • Restore LocalFriendCodeSeed and SecureInfo from backup.
  • Verify LocalFriendCodeSeed and SecureInfo.
  • Wipe temporary titles, expired titles, TWL titles, pending titles, demo launch infos, config, parental controls and CTRNAND.
  • Format (delete) SMDC root and NAND ext savedata.

User guide

FAQ

Q. What's the benefit in this?

Some people might be using a different friend code seed or SecureInfo from what their device originally came with. These people may not have ever made backups of their original files.

This app, counters that by re-creating the original files using the data stored in memory.

Q. I get err 0xd9004676 when trying to make a backup using 3DSX version?

Enable "Patch ARM9 access" in Luma's config.

Q. I get err 0xd8e007f7 when trying to do anything using 3DSX version?

Enable SM/FS patches under Rosalina's process patches menu.

Q. How does this restore your original secureInfo/LocalFriendCodeSeed?

This deletes the NAND SecureInfo/LocalFriendCodeSeed file, then re-creates it using the SecureInfo data stored in memory.

The SecureInfo and LocalFriendCodeSeed data is stored in memory initialized by the bootrom.

Q. Does this unban me?

No, and it'll never do anything like that.

Q. Will this mess me up?

Not really, the worst thing that could happen is wiping your config - which would delete all data for WiFi slots and other info in settings.

This also brings up the system setup on the next boot.

Q. Where are my backups stored?

/3ds/data/3DSRecoveryTool/backups/nand/.

Q. Where is my LFCS/SecureInfo dump stored?

/3ds/data/3DSRecoveryTool/dumps/.

  • New data path (/3ds/3dstool -> /3ds/3DSRecoveryTool).

  • Added option to dump original LocalFriendCodeSeed_X from memory. This option can be found under the misc submenu.
