3DS:Troubleshooting/multiple ID0

Required Reading

This page will assist with finding the correct ID0 in the case you have 2 or more. This can occur when using the same SD card on multiple consoles, or after reformatting your console without your SD card inside. This is a waste of space, as only the true ID0 can be used by your console.

Instructions

It is recommended to make a backup of your Nintendo 3DS folder before following these instructions.

1. Rename Nintendo 3DS to BACKUP_Nintendo 3DS
2. Insert your SD card into your console and power it on
3. Wait for your console to generate SD card data
   • Your applications will have disappeared. This is normal and will be resolved shortly
4. Power off the console and insert your SD card into your computer
   • You should now have a newly created Nintendo 3DS folder in addition to your existing renamed BACKUP_Nintendo 3DS folder
5. Determine the correct ID0 (32-character folder) in the newly created Nintendo 3DS folder.
6. Write down the first few characters of the folder you see
   • This is your true ID0, which we will keep in the real Nintendo 3DS folder
7. Delete the ID0 from the current Nintendo 3DS folder
8. Move the true ID0 folder from the BACKUP_Nintendo 3DS folder to the Nintendo 3DS folder
9. If it exists, move the Private folder from the BACKUP_Nintendo 3DS folder to the Nintendo 3DS folder
