    So I just got a Japanese N3DS. I kind of lucked out and it shipped on sysNAND version 9.1, so no need to downgrade (wow... Particularly lucky since the N3DS is the one that has the far larger chance of soft-bricks. I wasn't relishing the thought of going through all that.) This means I also have the benefit of a completely clean sysNAND.

    Anyway, I was looking at the region swap tutorials and I think I must have originally looked at something completely different because these definitely don't look right. They both want you to use a 4.x system for starters -- and I don't feel very comfortable with the idea of downgrading a N3DS to 4.x... I've already learned the hard way that downgrading mset won't work for software like that either since it has to be updated for the newer firmwares (offsets or whatever, I don't know) and the N3DS has different offsets besides I think.

    Is there a method using newer tools? Perhaps some that can run from Homebrew Launcher or CTRBootManager?

    I too am curious about this, I have a 9.2 Japanese O3DS and would love if my emuNAND was in English.

    sure it's possible. the the exact same process no matter the fw.
    swap secureinfo file and install fw. (swap the secureinfo file last)
    remove left over stuff :)

    get rxtools, open rxtools
    generate your nand 16 xorpad via rxtools copy this file on a folder with the ff tools:
    emunand tool, secureinfo tool

    get 9.9 u (full) or 9.5u (full) n3ds on your sd inside updates folder.

    install 9.9u (full) or 9.5u (full on your emunand) use sysupdater

    extract emunand from your sd with emunand tool

    select which emunand file to use in secure info tool
    select which xorpad file to use in secure info tool
    inject secure info a of your target region with secure info tool
    inject your emunand to yoursd with emunand tool

    boot your 3ds
    delete/hide duplicate titles.

    actually with decrypt9, maybe rxtools, you can inject decureinfo there.
    no need to do decryption on the pc really

    Yes, that was the guide I was thinking of. Now I wonder why I couldn't find it when searching... (Heck, I tried just searching for "region" in thread titles. That should have made it come up surely...)

    Anyway, I'll be giving the process a shot in just a bit. Thanks.

    They were using 4.x tools though. I can't do that. Or maybe theoretically a N3DS could be made to do it, but I'm not screwing with stuff like that except in worst desperation. (At least I have a sysNAND backup already. Did that before I did ANYTHING except run BrowserHax. I still don't feel confident about attempting a hardmod though and can't afford to get someone else to do it right now. I could probably do it, but I sure don't want to try.)

    you don't need special tools. you can do this all with decrypt9 and fbi

    I see what you're saying, but what I'm saying is those other guides all pointed to those tools that require 4.x.

    How do I extract the secureinfo from a donor system btw? I think I'll sacrifice my backup 2DS system so I can have a semi-legitimate emuNAND in case since 9.6's new encryption must be cracked SOME day and I don't think anyone I really trust is going to buy this system from me anyway.

    Same concept works on 9.1 emunand. Decrypt9 will let you dump secureinfo: https://gbatemp.net/threads/download-decrypt9-open-source-decryption-tools-wip.388831/

    Use Riku's tool to inject it: https://gbatemp.net/threads/release-3ds-nand-secureinfo-tool-for-region-change.383792/

    Don't follow his guide, just use his tool.

    No need to downgrade. I can make a new tutorial later if need be, but you can use the one you posted plus the tools I posted to make your life a bit easier.

    I apologize, you're right. I thought you were talking about following that guide exactly.

    If you region change your emunand will you be able to do OTA updates afterwards?

    Example: On N3DS I region change my 9.2J to 9.5U, then later when 10.3 emunand becomes a thing can I just update through system setting or would I have to use sysupdater?

    why use the tool? does decrypt9 not allow you to inject the secureinfo file?
    test on an emunand first if you are worried.

    yes you can update fine...

    I'm having troubles getting decrypt9 to even run so far. It just blackscreens. Even using their boot.3dsx. I'll probably have to stick to the xorpads with rxtools.

    You may need to run Pastacfw first to patch sig checks

    Black screen even in "Pasta mode." Just freezes on the menu if I select it using their boot.3dsx. Do I have to run actual literal PastaCFW specifically? That could be kind of a pain to get this to run with that if so...

    I think I'll give up and do this the hard way with the xorpads and all. It's a royal hassle, but decrypt9 doesn't seem to have any desire to run on any of my systems at all.


    EDIT: rxTools has an option "Dump NAND Files" which has a SecureInfo_A option in it. Similarly it can inject.


    So now I just have to make it through the CIA installation part. Ugh. My version of DevMenu must be different, but I don't see anything specifically stating "6.22" like the tutorial specifies anywhere so far. Either way, it does not continue if there is an error despite what they claim there.

    i use homemenuhax, and decrypt9, the latest on the github, works perfectly for my n3ds 9.2
