NOTE: I AM NOT RESPONSIBLE IF ANYTHING HAPPENS TO YOUR SYSTEM

  1. Grab the sysUpdater app from [Click here to view this link]
  2. and place it into the '3ds' folder of your SD card.
  3. Make a folder called 'updates' on the root of your SD card.
  4. Place all of the CIAs for the update you wish to downgrade to into the folder. (Google is your friend)
  5. Insert your SD card into your 3DS
  6. Open up the Homebrew Launcher in your entrypoint of choice and start the sysUpdater app.
  7. Press "Y"
  8. Wait and don't touch anything. The app will tell you when it is done.
  9. Once the app says that is is done wait It will restart itself.
Issue: The app freezes at a certain step!
Solution: Try a different entrypoint. I was using Ironhax and got this problem, so I switched to OoT3DHax and it worked.

Issue: The prompt comes on screen, but nothing happens when I press a button!
Solution: Either wait a few moments or reboot the system and try again.

Issue: I downgraded, but my 3DS screen is completely black upon reboot!
Solution: Try removing the SD card, or you can reboot into recovery mode.

I'm downloading the 9.2.0-20U firmware with 3DNUS. Should I just put those files on the 'updates' folder?

Is there a way to back up and restore the system NAND in case something goes horribly wrong?

This is causing a lot of bricks on New 3DS systems so be very careful. Also if you're downgrading a Japanese system remove the 000400102002CA00 title otherwise you'll brick the console.
