DISCLAIMER: THIS IS AN EXTREMELY OUTDATED METHOD OF DOWNGRADING. USE PLAILCET'S GUIDE PLEASE.

PLEASE NOTE: JP N3DS Users, you'll need to remove the 000400102002CA00 title in order to not get bricked! Not sure if other regions need to do this as well.



ALSO NOTE: I AM NOT RESPONSIBLE IF YOUR 3DS BRICKS . If it does, I'm sorry, but it is NOT my fault.

TUTORIAL:

Grab the sysUpdater app from here and place it into the '3ds' folder of your SD card. Make a folder called 'updates' on the root of your SD card. Place all of the CIAs for the update you wish to downgrade to into the folder. Eject your SD card, put it into your 3DS, and boot. Open up the Homebrew Launcher in your entrypoint of choice and start the sysUpdater app. If everything goes well, you should have some options. Since we're downgrading, you can go ahead and press the Y button. Wait and DO NOT touch anything. The app will tell you when it is done. (It took me less than 5 minutes)

Once the app prompts you that it is done, wait. It will reboot automatically. Bite your fingernails in suspense. If everything goes correct... Your 3DS will be downgraded!

COMMON PROBLEMS:

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. To do this, hold A+R+L+Up as your 3DS turns on.



(please recommend any other issues and solutions to add here please!)
