    DISCLAIMER: THIS IS AN EXTREMELY OUTDATED METHOD OF DOWNGRADING.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

    Hello!
    In recent days, there have been many developments within the 3DS homebrew community, with one of them being kernel access! With this, we now have a way to downgrade 3DSs and do whatever we want with kernel on >=9.3 3DSs. What's that? You want to downgrade? Well then, here's how...

    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.


    CIA STUFF:

    Need some firmware CIAs and can't find them? Never fear. Even though I can't directly link them here, I can tell you that if you Goodle (including the quotation marks) "[MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions)" you may just find what you're looking for. ;)
    You can verify that you've gotten the right .zip file and that everything is okay by comparing the file's MD5 and SHA-1 hashes (generated on this great site) to this handy chart below.
    TUTORIAL:
    Before beginning, remove any DNSs (like Tubehax) that you may have on your 3DS. This can interfere with the downgrading process. You may also want to back up your SD card juuuust in case...
    1. Grab the sysUpdater app from here and place it into the '3ds' folder of your SD card.
    2. Make a folder called 'updates' on the root of your SD card.
    3. Place all of the CIAs for the update you wish to downgrade to into the folder.
    4. Eject your SD card, put it into your 3DS, and boot.
    5. Open up the Homebrew Launcher in your entrypoint of choice and start the sysUpdater app.
    6. If everything goes well, you should have some options. Since we're downgrading, you can go ahead and press the Y button.
    7. Wait and DO NOT touch anything. The app will tell you when it is done. (It took me less than 5 minutes)
    8. Once the app prompts you that it is done, wait. It will reboot automatically.
    9. Bite your fingernails in suspense. If everything goes correct...
    10. Your 3DS will be downgraded! :D
    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!)

    There is an optional little thing you can do here that helps collect data about the 3DS downgrade process. Do it if you feel like it. :)

    It's safe as long as you don't do anything stupid.

    Note: So far NO ONE HAS BRICKED THEIR 3DS FROM THIS. The only person who actually bricked his 3DS could have recovered it by entering safe mode, but he had the TubeHax DNS and so it didn't allowed him to update.

    You should add this to OP, @TheStoneBanana: please remove any custom DNS before downgrading.

    You should warn that Japanese users of a New 3DS must remove the title 000400102002CA00 if they don't want to get a brick.

    Please please PLEASE GUYS, I know you are itching to get recognition on this magnificent virtual space, but start to get real info before spouting nonsense, I see this everywhere, people who are not up to date and say things that aren't current anymore. This build fixed the CFW installing problems

    Please stop doing this.
    It's not safe until the developers have thoroughly tested it and confirmed it's safe.
