    Hello !

    I made the CFW trick on my New 3DS but I saw in the guide that Luma3ds is kinda unstable on 11.4 as it is not adapted yet to it and I actually crash quite often when I try to play some games when I stop acting for like 5 minutes, it happened many times on Monster Hunter Double Cross and one time on Hyrule Warrior Legends. So I would like to know if there is a way to go on 11.3 or to at least stop all those crashes.

    Thanks per advance

    You can only downgrade if you have a NAND backup that's 11.3

    Use GodMode9 to restore the NAND backup the guide had you create. If you don't have a NAND backup, use 3DNUS to download the 11.3 firmware.

    But since I did the guide while I was on 11.3 the nand backup will be in 11.4 no ?

    No, it makes a backup of the NAND you were on before you installed A9LH and CFW which in your case is 11.3.

    Follow this to restore your NAND backup:

    Section IV - Restoring the System
    1. Boot your device while holding (Start) to enter GodMode9
    2. Navigate to SDCARD -> ctrtransfer
    3. Press (A) on <serialnumber>_nand.bin to select it, then select “NAND image options…”, then select “Restore SysNAND (safe)”
    4. Press (A) to unlock SysNAND overwriting, then input the key combo given
      • This will not overwrite your arm9loaderhax installation
    5. Input the key combo given to unlock SysNAND (lvl1) writing
      • This process will take some time
    6. Press (A) to continue once it has completed
    7. Press (Start) to reboot your device

    In 3DNUS simply out the version number in the ID and your region in the version section.

    With a program like sysdowngrader, make sure you make a NAND backup in case something messes up.

    I've been doing some research and if I'm reading everything correctly since I am already on 11.4.0-37u I'm screwed until a new exploit is found. There is no way to downgrade (since I don't have a NAND backup) relatively safely.

    You can't downgrade at all, not just that you can't 'relatively safely.'
