    Hi, I try to install A9HL in a O3DS but when i try to downgrade for install it, appear the next error:

    A9LH note detected, checking FIRM0...
    FIRM section2 hash mismatch
    Not running from A9LH, but FIRM0 corrupted
    Fix your FIRM0 or run from A9LH
    Auto CTRNAND Transfer: failed!


    I try with 3 SD Cards and all give me the same error. The files is in the correct folders, Can anybody help me? Thank you so much.

    Does this occur on 2.1 CTRtransfer?
    Weird, I never saw a case that FIRM0 corrupted before installing A9LH before.
    Does the conolse got hacked before?

    Yes, the actual firm of the console is 11.2.0.35E and I like to downgrade to install A9LH. In this step is when the console give me the error. I think not hacked before but i cant confirm that because the console is second hand.

    Did you have any files that got replace while doing A9LH?
    Did you have luma\config.bin?

    I had the saaaaame problem with a customer's 3DS.
    And It would not open fast/safe hax, just after a dozen of tries.
    Nothing would work, neither hardmod with nfirm downgrade, so I decided to use DSIWare method to downgrade the Firm and...

    It Bricked! :(

    The only way I can think of to fix a corrupt firm0 would be to downgrade to 9.2 using sysupdater. However that would require you to go the old route of using the dsiware downgrade first.

    Disclaimer: I'm not an expert but I do read a lot.

    EDIT - I just so the post above. Don't do that.

    No, but it may signify that your console had CFW (and hence likely A9LH) installed previously, and its uninstallation prior to you having bought it may have caused your corrupt FIRM0, which prevents you from performing a CTRtransfer. I'm not sure if there's any way around this, to be honest.

    Sorry I havent this file. Have any other form to install A9LH? Or LUMA with emunand? The 3DS is for a child.

    Don't think there's another way, unless someone does a app to replace firm0(are those universal? Or is Firm0 console specific?)

    i had 3 or more 3ds like that
    i can access decrypt9 with safehax, but the result
    A9LH note detected, checking FIRM0...
    FIRM section2 hash mismatch
    Not running from A9LH, but FIRM0 corrupted
    Fix your FIRM0 or run from A9LH

    i think its because u already hack the 3ds change region but dont get a9lh, because i check with decrpt9 there is no a9lh
    i dont know how to solve this problem yet
    *icant do dsiwarehax because cannot access eshop
    (sorry my english not good)

    everything in any firm is encrypted with a console specific key (this particular key is in the movable.sed file for ctrnand, but I think firm0/firm1 use something different...? OTP related?) but firm0/firm1 get updated with a firmware install, don't they? I would think forcing an install of native_firm would sort out the corruption issue, but on 11.2 I don't know if that can be done. If you can launch LUMA3DS on your system and then HBL on top of that, I might try launching fasthax from there, and then FBI to see if you can't force a native_firm install.

    3dbrew will tell you exactly what the filename is for native_firm for your system, but you'll probably need to search around (the iso place maybe) for that file...

    I think the FIRM0 corrupted is in the 3DS.
    Thank you so much @urherenow, but what is the programm I need to install a native_firm? Sysupdater? I can enter on homebrew launcher with fasthax

    Maybe the previous user installed A9LH and never Uninstalled it, just cleared the SD card. Have you tried running a payload?
