    Hello everyone

    I downgraded from 11.2 to 2.1 with sysupdater but it gives me black screen after boot in installation it said all files were good and to hit select to reboot but emunand works any fix? My original firmware is 11.2 downgrade purposes was to reinstall a9lh

    Note: sysnand turns on but only gives black screen

    Thanks in advance

    You downgraded with sysupdayer? That method hasnt been used since like march...there's ways to downgrade now without hassle, Litterally drag n drop one file and hit transfer in decrypt9 to downgrade to 2.1....
    Head over to 3ds.Guide

    I'm still confused, You used Sysupdater to downgrade which is outdated and did the CTRTransfer while emunand still being able to boot, tell me the steps you did

    If you can boot to Decrypt9, you already have A9LH, so why are you trying to go to 2.1?

    You already have a9lh? You are using Luma3DS?

    If the answer these are yes then it's working the way that it is supposed to. Luma3DS is not capable of booting the 2.1 firmware. The only way to load that firmware is to uninstall a9lh, but that would be really stupid. Kind of like downgrading to 2.1 using sysupdater.

    Also if you have a N3DS downgrading to 2.1 with sysupdater will cause an instant brick every time without the right tools.

    Did you research any of this before starting?

    3ds.guide is all I can say. Unless I'm wrong you should be able to do a ctrtransfer, :)
