User:KittyCatGabbi/Recovering save data

This page is a guide on how to salvage save data from SD cards that didn't go through Finalizing Setup and have no homebrew applications installed, or to those that have found their SD card to be corrupted. Two common signs of corruption are HOME Menu applications disappearing after the SD card was interacted with, and issues with applications, such as broken banners or icons in the HOME Menu, Luma ErrDisps stating the SD card was removed, as well as unknown applications displaying in Data Management.

What You Need

• The v3.7.4 release of Checkpoint (the .3dsx file)

Prep Work

1. Power off your console
2. Insert your SD card into your computer
3. Copy Checkpoint.3dsx to the /3ds folder of your SD card (not Nintendo 3DS)
4. Reinsert your SD card into your console

Section I - Recovering

1. Power on your console
2. Follow the instructions to manually enter Homebrew Launcher
3. Launch Checkpoint
4. Hold B to refresh games list
5. Hold Y to select all games
6. Press Left Shoulder to backup all saves
7. Press X to switch to extdata
8. Hold B to refresh game list
9. Hold Y to select all game extdata
10. Press Left Shoulder to backup all game extdata

If your SD card was showing corruption signs, it is extremely advised to format your SD card, test it for errors and restore Luma on an empty SD card before proceeding to restore your save data. Do NOT restore your Nintendo 3DS folder to the new setup, or errors and further corruption are likely to keep happening.
