    If you own a 3DS with firmware 11.0 or 11.1, it's possible to downgrade it to 9.2 and eventually install arm9loaderhax. This involves buying a Dsiware game on a hacked 3DS, installing a custom save file, then system transferring it to the 11.0/11.1 3DS. This will remove the NNID from the target 3DS so be sure you're willing to sacrifice it along with other save data. You'll have to wait 7 days before you can system transfer back to the original 3DS (3DS #1)


    REQUIREMENTS:
    - A hacked 3DS (Preferably with Arm9loaderhax installed on it) 3DS #1
    - A 3DS on stock 11.0 or 11.1 firmware 3DS #2
    - Purchase a specific Dsiware game such as Legend of Exidia on the hacked 3DS


    Before you begin:
    On the 11.0/11.1 3DS, make a backup of all save data for all the games you care for on both 3DS. You'll need to boot into Homebrew Launcher and use JK Save manager to backup the saves one by one. You can restore them once you've finished this entire guide. You'll need an exploit game such as Cubic Ninja or Freaky Forms Deluxe to access Homebrew Launcher on this 3DS. Or a prehacked 3DS that can install an exploit on Paper Mario Sticker Star or Pokemon ORAS.




    I. Dsiware Downgrade method
    This will downgrade Native_Firm to 10.4, in which you can then run Homebrew Launcher via steelhax to downgrade to 9.2


    II. 9.2.0 Downgrade
    After adding the 9.2 update files on your SD card, Launch Steelhax from SteelDiver to get into Homebrew Launcher then run SysDowngrader and press Y to downgrade


    ----------------------------------------------------

    III. Arm9loaderhax setup
    These next steps will guide you to setup the best level of hacks, known as Arm9loaderhax. This enables CFW to load up as soon as the 3DS boots up. The steps are written by Plailect, his guide is the best you'll ever find for setting up A9LH. Start from part 1 and work your way up to part 3 of the guide. Don't be overwhelmed by all the text, you only need to follow from where it says "What you need" and "Instructions" on each part.



    Old 3DS Steps
    1) Launching Decrypt9
    2) 2.1.0 ctrtransfer
    3) Installing Arm9loaderhax


    Warning: DELETE the A9LH folder! Then add a fresh one during section I. You don't want to mixmatch the other system's OTP or else you will brick!


    New 3DS Steps

    1) Setting up Menuhax
    2) Launching Decrypt9
    3) 2.1.0 ctrtransfer
    4) Installing Arm9loaderhax


    Warning: DELETE the A9LH folder! Then add a fresh one during section I. You don't want to mixmatch the other system's OTP or else you can brick!

    *Use browserhax on section II of Installing Arm9loaderhax (Holding L+R on home menu, scanning THIS QR)




    Once you've finished, I created a starter pack you can use to get started. These are apps I highly recommend having on your 3DS. Simply drag and drop all the files from the zip onto your SD card. Install all the cia using FBI, located in SD:/Cia/Homebrew/

    Download

    Here's a list explaining what each app does: HERE

    How do you use the save manager to back up your saves on 3ds#2 if it has no CFW? I am confused on that step

    You have to use homebrew to backup the saves on 3DS 2. You'll need to buy a specific game to be used as an entrypoint such as Cubic Nina or Freaky Forms Deluxe.

    NNID is tied to each system, if this system was the original system for that NNID then yes you can log into it. If anything give it a try and see how it goes.
