    I was following the guide for the new CFW method, but things got too complex at getting the OTP so I just wanted to go back to the way I was booting into emunand via the DS profile exploit on 4.x sysnand. I've restored my sysnand and emunand to the backups I made, but I've lost the health and safety app to be able to inject FBI into it, even after formatting the system memory.

    Could someone please help me on getting my 3DS to being able to boot into emunand again? Thanks.

    if you have anyother entry point you just could install the fbi cia via the hb fbi version.

    You stopped at part 4? That should have been good enough!

    If you have everything you did when you started, I would suggest you follow the steps again from part 1 and stop after you've injected FBI in part 4.

    If not, I can still assist. Are you on 9.2?

    also my emunand lost its Health and Safety app, what i had to do is creating a new emunand.
    but that will be tricky if it is sysnand.

    What do you mean by entry point? I can still launch stuff via the browser. What's the hb version of FBI?

    Right now I'm on 4.x. I restored my old 4.x sysnand and my old 4.x emunand, so I'm assuming all of my games and saves are still there I just need some way of booting into it.

    FBI is the app that you will inject in the health app to install cia. But you also can launch the homwbrew launcher and start the homwbrew version of FBI to install cia, even FBI iteslef and possible the health app

    An entrypoint is basically a way to launch custom/unofficial software on the 3DS, tricking the system to launch a "payload" file such as the menuhax_ropbin, arm9loaderhax.bin, boot.3dsx, and so on. MSET ROP (System Settings DS Profile), A9LH, menuhax and browserhax, OoT3DHax, and Cubic Ninja are some examples of entrypoints.

    Are you sure you aren't interested in updating to 9.2? You can install the menuhax entrypoint so you can enter your CFW/HBL the moment you power on your system.

    Anyway, do you have a DS flashcart?

    I don't think I can even upgrade to 9.2 again because it involved injecting the health and safety app which I no longer have. I don't have a DS flashcart.

    USA doesn't have a 9.2 update. The closest you can get is 8.1U via Smash.

    Anyway, let me look for solutions for your situation. Even if you got MSET working via spider, you can't do anything without FBI...

    EDIT: Wait. Have you checked if you have FBI or Health & Safety when you run DevMode in RxTools?

    Ahh that's right! I thought that was a rare cart to find though? I wonder.

    In any case, I'd like to see if we can find a free solution to this before that. My next guess is to try to inject FBI via Decrypt9, but we need to see if this user truly doesn't have H&S.

    If I were to upgrade using this method, how would I boot into my emunand from browserhax? This method isn't idea as it would only successfully boot 75% of the time as I was following the guide for the new CFW method.

    I'll try and see if I can start DevMode.

    That's true, except if you replace a file you can kick that up to about 80%.

    if you follow the guide all the way through part 5, you'd get a 100% boot in 8 seconds, and you won't even need EmuNand anymore nor worry about future system updates. I'm willing to guide you through that if you manage to get FBI or Health & Safety back.

    The H&S app appears in DevMode, but starting it does nothing.

    Okay cool, can you download Decrypt9, put its Launcher.dat on your root, then go to go.gateway-3ds.com on your web browser?

    It should run Decrypt9. Let me know if you can select SysNand Options -> Dump Health & Safety to hs.app

    I can boot into Decrypt9WIP and I have a 9.2 NAND backup. If I restore this
    I can boot into Decrypt9 but trying to dump the H&S app just gives an error. I have a 9.2 NAND I could restore and install menuhax again, but if I do is there a way for me to boot my emunand?

    Oh yes, just restore your 9.2 NAND, set up menuhax, then set up Luma3DS and you're good to go (Luma boots into EmuNand by default)

    (For the record, if you have hs.app from earlier before you undid the process, you can actually just re-inject FBI_with_banner.app and it'll give you back FBI on SysNand... But restoring 9.2 is way easier honestly)
