    I have a Japanese 3DS.

    I just go in my Gateway 3ds. Downgraded to 4.4. Installed Emunand. Updated that Emunand. Everything was working correctly. I go into the eshop for the emunand, but I can't read Japanese so I thought it was just asking me to create my mii or Nintendo Network ID I hit ok until I see it's installing another firmware.......

    It finished installing and My 3DS is now on 9.9J. Man I want to shoot myself. I didn't even get to enjoy the Gateway....

    Your Sysnand is now on 9.9?
    Did you make a backup of your Sysnand from the Gateway Menu like you were supposed to?

    If yes to the above two questions, then you can do a hardmod / have one done & flash your 3ds back to an exploitable firmware.

    Yes, I did back up the Sysnand. How do I hardmod it? Do I have to buy something else take apart the 3DS?

    Or send it to @hundshamer and he can do it for you for a fee. Iirc he charges $50(?)

    Edit: There are other Hardmod guides that may be a bit simpler, you'll just have to google / search the forums for those. I don't have'm saved. :P

    Thanks for the links. I'm googling right now, but haven't found anything straight forward yet.

    It's pretty good. I've soldered mod chips before back on PS1 and PS2.

    I'm assuming it's not a "new" 3DS, because of the downgrade part. Is it an XL or no?

    It's an old 3DS XL.

    That's the easiest one. There are 4 points. They are DAT0, CMD, CLK, and GND( you can ignore DAT1, DAT2, and DAT3)). Solder them to an SD card's corresponding pins. Use win32diskimager to dump the 9.9 NAND twice and compare them (via MD5 or SHA hash) in case of error. Then write the 4.x backup to the NAND with win32diskimager.

    I see thanks. I made a NAND dumb of the original when it was at 5.X. Is that fine or did I really need a 4.X backup? Also, how does win32diskimager allow me to create a new NAND dump for 9.9? I thought I wouldn't be able to create any dump because I don't have Gateway access. Also, if I connect the pins how do I dumb with win32diskimager? How do I connect the SD card I mean to a USB/SD slot?

    Your 5.x dump is fine and win32diskimager has a read/write feature.

    How does the SD card connect to the PC so I can use win32diskimager? Sorry, for asking so many questions.

    You need an eMMC (or was it MMC) USB adapter for your SD card @hundshamer can tell you a specific USB reader.

    But if you entered eshop in emunand only your emunand updated to 9.9 yes? Or where you in sysnand by mistake?

    I went to emunand. Went to system settings to check the version and saw GW 9.9. Backed out by closing via the button on the menu. I'm guessing leaving that screen reverted back to my sysnand for some reason.

    Somewhere in this potatoland!
    When it all works out fine, and you downgraded to 4.4 back, make a new nand dump of your 4.4
    The more NAND dumps you have the better ;)

    Exiting from System Settings will always reset the console and it will load sysNAND :(
    I wish luck on your NAND flashing.
    Tip if you succeed to restore your NAND backup, create folders in sysnand and emunand with different 1st character or use themes on emunand, to differentiate them.

    No no...
    All you need is a micro SD adapter (to make micro SD card to normal SD card) disassemble it and solder pins with the photo mentioned above by hundshamer. Keep the wires as short as possible to avoid any read/write errors.
    And you need a SD card reader, if you have an external SD card reader or the one you have on the laptop give it a try. If there is some errors not able to get correct dumps then look for Anker SD card reader to buy (a specific model, look in topics or ask hundshamer for assistance).
