How do you rollback from TWL_FIRM (or restore a TMD) ?

    I finally decide to move from emunand launched with Menuhax to A9LH mainly because I want to run my M3 DS Real on my 3DS, so a few month ago I deleted the blacklist title id (0004013800000102) from the nand then I realised that my linker wasn't compatible with this method. Now, I tried with A9LH and the M3 DS Real specific patch ApacheThunder but first I need to dump my OTD.bin but since I don't have the twd on my sysNand I always get a "validation stage 1 failed" because the twd is missing. So what do I do now ?

    I already format my sysNand with the stock formating tool in the settings but it doesn't change the result.

    The error:

    Reinstall the title key, which you can find on 3DNUS.

    I just tried it, but when I try to install the title key with FBI in SysNand it tells me that it's already installed (even if I don't find it while browsing the NAND)

    Use Sysupdater to install the cia.
    https://github.com/profi200/sysUpdater/releases/tag/0.4.2
    (place the cia into the "updates" folder, at the root of the sd card)

    • Make sure you use the correct one for your console, ;)

    I just launched sysUpdater in SysNand (via devmode with an old RxTools) but i have a brick warning, should I do it ?
    EDIT 1 launched it via the Homebrew Laucher instead and I get
    "main.cpp:154: Result: 0xD900182F
    Failed to get CIA file info".
    EDIT 2 I tried to delete the "0004013800000102.cia" from the update folder, the DS gave me a crash screen before the beginning of the Downgrade
    EDIT 3: I installed the cia with sysUpdater via Rx Tools Dev Menu, it said installed. I launch OTD Helper and still got the same error.

    The only thing I plan to do is reflash the sysNand, but since it's not an update and not an upgrade I don't even know where to start.

    If you have A9LH, make a SysNAND backup and uninstall the title and then install the new one.

    I don't have it, the point of all this thread is dumping my OTD to install A9LH

    Alright, I'm not sure so I would wait for other people to respond, but I would uninstall it in FBI and install the new one.

    I was using the last l33t version, I just install to 2.4.2 in the devmode and the installation of 0004013800000102.cia worked (it was diplayed in the title list), so I downgraded my Emunand to 2.4.0 but when I launch OTDHelper it stills tell me that my the title 0004013800000102 was not found, i'm gonna install TWL_FIRM with the latest FBI and see if it works that way

    EDIT:
    Still got the same error in OTDHelper when flashing TWL_FIRM.cia, i'm kinda out of solution right now

    TL;DR It's Fixed

    Forget everything upper than this post, I hope a moderator will edit the header/title to something like "How to remove TWL_Firm modifications to install A9LH"
    Since almost everything about A9LH is repertoried into the phailec guide you i'm pretty don't have the solution for this issue anywhere else than here, so I decided to do a tutorial (sorry for my gramatical errors btw, English isn't my primary language)

    For o3DS (I thin it's the same for new3DS but with another file)
    You need
    • The newest version of FBI (not the terminal like one), it doesn't necesserly need to be injected inside of health and safety you can install it anywhere on the SysNand via devmenu/minipasta
    • 3DNUS
    In 3DNUS enter 0004013800000102 in title ID and 8817 in version
    3DNUS sould generate the file "0004013800000102.cia" into is folder, it's the unpatched TWL_FIRM (for o3DS)
    Copy the file in your SD card and boot FBI from sysNand
    Go into titles
    Find "0004013800000102" in the bottom, press A, select "Delete Title And Ticket"
    Return to FBI main menu, go to sd and install 0004013800000102.cia
    Then the One Click Setup from OTDHelper should work properly.
