3DS:Troubleshooting/multiple ID0

Required Reading

This page will assist with finding the correct IDO 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 your the 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 (which is currently BACKUP_Nintendo 3DS )
7. Delete the Nintendo 3DS folder
8. Delete the incorrect ID0 in BACKUP_Nintendo 3DS that doesn't match the one you wrote down
9. Rename BACKUP_Nintendo 3DS to Nintendo 3DS
