    Have 2 N3DS units in this state: (Both a9hl)

    Both when you power them on they get the blue screen with:

    Bootrom 8046
    Errcode: 00F800FE
    00000000 00000000
    00000400 00000000

    They are both hardmodded with a USB port, if I connect them to a computer and power them on (like I would normally do if I wanted to back the NAND up or reflash)

    I get:

    Bootrom 8046
    Errcode: 00F800FE
    00000000 00000000
    00000400 00000000

    And Windows does NOT pop up a box asking me if I want to format the drive, like it normally does. And Win32DiskImager does NOT recognize it. (for BOTH of these N3DS units)

    One of my kids somehow got both of these into this state, not exactly sure how. They said they were playing a certain game (same game) on both right before it happened, this game they have used many other times before.

    I have 3rd working N3DS here that is hard modded, and when I plug in the same USB cable and connect to windows and boot it, it gives the

    Bootrom 8046
    Errcode: 00F800FE
    00000000 00000000
    00000400 00000000

    But is accessible with Win32DiskImager (can read and write the nand), so I know my hardmod setup for the PC side is fine still.

    Any idea what I can do with these 2 in this state to recover them, or what could be going on here?

    Thanks

    Did your kid plug in higher voltage power supply into the 3DS, 3DS use 4.6V and 0.9A, anything higher than that might have damaged the eMMC controller that control Nand and SD card Adapter.

    My kid just told me they plugged a USB cable into the USB charger into my micro usb hardmod port on both N3DS units.

    Would that do it.

    So the question now, is when a hardmodded N3ds that has a micro USB port wired to the N3ds, if you plug it into a USB charger, is the N3ds toast at this point? I assume the MMC or whatever it is called is gone now.

    And that is why it is NOT detectable.

    If voltage was apply on the hardmod port then it means that it most likely fried the eMMC controller onboard, that why you get the bootrom 8046, I also have a hardmod 3ds but I only get 8046 if I connect the adapter and plug in the SD Adapter into the computer.

    Thanks guys, I guess I am screwed then. I can't believe they did to both units.. Dar,n guess I should not have used a micro usb port for the hardmod.

    Im just rather curious as to why you thought that you needed to have usb ports on a 3ds system

    Curious why you say I should never of hard modded? This was when the N3DS units were new, and I actually used the hardmod a few times over these two units lifetimes. Where I re-flashed the original nand back, or reflashed a backup while I was messing around with something that did not go right. They actually came in handy several times. (the hardmod)

    I would assume familiarity and convenience.

    Too bad about the voltage thing though :ninja:

    For the hardmod, the micro USB port was used for ease of use and was connected to the nand on the N3ds, I had a micro sd adapter with a male micro usb cable that I could then plug into it to reflash or copy the nand.

    I never considered the fact that someone might come along and plug a USB cable into the port, and plug it into a USB charger directly. Short sighted on my part I guess.

    So are there still N3DS units out on the shelves out there that are still fully hackable like these 2 that got killed, or we at a point where they are hard to come by? I guess I need to do new research :(

    Well they are little kids, at least you modded it yourself, so it doesn't cost yourself too much as opposed to hiring someone to mod it for you. Wouldn't be too bad if you had case blocking the modded port.

    If you are familiar with the ntrboot method. Then all consoles are vulnerable to it. Unless nintendo was to make new consoles with a new bootrom. There is not a way to patch that on any firmware they make.

    Thanks that is good to know, I will learn about that then and at least I can replace these then and get back to the same level of being hacked. I was a little worried we were at a point that there was no window. Guess I have to rearch ntrboot then.

    Thanks

    There is also seedminer that you can look at aswell if ntrboot doesnt suit your fancy. https://gbatemp.net/threads/seedminer-single-system-dsiware-injection.495685/

    Just take a look at https://3ds.hacks.guide for all your options.
    That's the only guide you should be looking at, don't trust any others. Especially youtube vids.
