    I have a O3DS XL, downgraded from 9.2 to 4.5 with gateway's downgrade tool

    First I'd like to say that I'm on 4.5 and I decided to move from Gateway's ancient system to a more recent Luma3DS with the help of 3ds.guide
    I have downgraded with gateway's method in the past from 9.2 to 4.5 when that first came out.

    I followed 3ds.guide and got to the end of the first page of the guide
    However, when the 3DS rebooted it greeted me with:


    I decided to ignore this as the guide said "If you get and error, just continue to the next page"

    However, I got until the end of the first section of "Finalizing setup", and it says to:
    I still get the same CTRNAND FIRM error.
    Any help?

    NOTE: I can access godmode9 when I press and hold START when the 3DS is booting up.

    UPDATE:

    I fixed the issue by using the godmode9 access I had, and restored my ancient 9.2 NAND.bin file I stored when I first used gateway.
    Now I am on 9.2 safely.

    Restore a NAND backup. There should be instructions here https://3ds.guide/godmode9-usage

    If you are new to the scene and don't have an old NAND.bin then you may have to go follow the CTR Transfer guide, essentially using someone else's public dump and modifying it to be flashable to your 3DS

    I'd say go to here
    These scripts are supposed to help with unbricking if you don't have a NAND
