    Ok so I explained what error I did ( I want to mention that I don't have a nand backup).
    1. I download the files for the update (the 11.2.0-35U on 3dnus).
    2. (This is really stupid I know) I install the cia of the update with fbi.
    3. My 2ds on 11.4.0.-37 worked afer the install so it seems ok but when I restart the error appear on boot.
    Somebody could help me on this?
    I can actually access to the luma chainloader and luma config menu but I can't access the home menu.
    A big thanks for every helpers and have a good day.

    You must do a ctr transfer to 9.2 you lost all your saves

    i had the same issue

    ctr transfer to 9.2 then updateing has fixed it.

    Wait? Does CTR transfer work in 11.4 ?
    I know you probably can't give link but can I find the 9.2 version in 3ds.guide?
    Thank you so much! I'm glad that people like you take their personnal time to help other peoples.
    Do you know if a firm. app that can extract save exist or godmode9 can do that?

    safectrtransfer makes a mandatory nand backup, regardless if you want one or not. See if you still have it.

    your 3ds is kaput, its' nand is corrupted. If a nand backup was made during that transfer you can fix it. Obviously dont backup your corrupted nand.

    a guide to recover your NAND? you don't really need one. just use godmode 9. press, I think it's home, to get a list of options one of which will be backup/restore NAND.

    You dont need one. First tell me if you can find a nand.bin or something like it such as nand_min.bin anywhere on your 3ds sd card. then we'll go from there.

    Oh no that's not what I mean. I mean that I would want to follow a guide for safe ctr transfer.
    Sorry for the error I am french.
