    Tutorial: How to region change an original, Japanese N3DS' emuNAND to USA/EUR
    WARNING: I am not responsible for any damage to your system. Follow each step carefully and don't cut corners.

    Also, this may remove all installed applications on your emuNAND.
    Requirments
    • A Japanese non XL/LL N3DS (obviously) running <= 9.2 sysNAND.
    • A computer.
    • An emuNAND running 9.2 - 10.4 with CFW that disables signature checks.
    • A donor SecureInfo_A from any 3DS (Old, new, xl/ll, non xl/ll) running the target region (US/EUR) on your SD card. *Note online games and such may not work properly on the donor console and/or your console if the donor has connected to the internet using the same SecureInfo_A
    • A CIA version of a CIA installer installed on your emuNAND.
    • 3DSNUS on your computer.
    • A way of running .3dsx preferably menuhax on your sysNAND.
    • Decrypt9WIP by d0k3 installed as a 3dsx.
    • The update/downgrade CIAs for your same emuNAND firmware and for your target region from that ISO site. Hint: It's the ones everyone has been using to downgrade their sysNAND. Extract the updates folder to the root of your SD card.
    Step A: Backing up your emuNAND if something goes wrong
    1. Start up Decrypt9WIP through the Homebrew Launcher and select "EmuNAND Options".
    2. Select "EmuNAND Backup" and choose the name for it to be stored under.
    3. Grab a snack and wait about 10 - 20 minutes.
    4. After the backup process, power off your console.
    5. You have completed step A.
    Step B: Installing the update/downgrade CIAs for your target region

    1. Boot into your emuNAND with a CFW. Preferably Cakes.
    2. Start your CIA installer that features batch folder install. Preferably FBI.
    3. Go to the updates folder you extracted and install all the CIAs. If you are using FBI, press X while in the updates folder.
    4. Do some exercise and burn off that snack you just ate for 5 - 10 minutes. :P
    5. If all CIAs installed successfully, power off your system.
    6. You have completed step B.
    Step C: Injecting a target region SecureInfo_A into your emuNAND

    1. Power on your system.
    2. Start the Homebrew Launcher with your preferred exploit.
    3. Start Decrypt9WIP
    4. Go to "EmuNAND Options" -> "File Inject..." -> "Inject SecureInfo_A"
    5. Follow the safety check displayed on your screen.
    6. Choose the file name of the donor SecureInfo_A and press A.
    7. It should finish in about 5 seconds.
    8. If the Inject succeeded, power off your console.
    9. You have finished step C.

    Step D: Cleaning up

    1. Boot your emuNAND.
    2. Wait for 2 - 3 minutes until it boots. Note: You may be missing some system applications, don't panic as this is normal. Go to Step E (after finishing this step) if they are.
    3. After it finishes booting, open System Settings and format your system.
    4. After the format finishes, reboot into emuNAND and finish the setup.
    5. Note: If your CIA manager is gone, don't panic. You can follow this https://gbatemp.net/threads/release-inject-any-app-into-health-safety-o3ds-n3ds-cfw-only.402236/ guide to inject your CIA manager into your health and safety application.
    6. Now, on your computer download a csv title list from yls8.mtheall.com/reports.php for your previous fw region/version and for your new fw region/version.
    7. Use this https://gbatemp.net/threads/release...is-safe-to-delete-after-region-change.383796/ awesome tool by cearp and get all the safe title IDs you can delete.
    8. After getting a list of title ids, something similar to " ['0004001000020000', '0004001000020100', '0004001000020400', '0004001000020900', '0004001000020A00', '000400100002BF00', '0004001020020300', '0004001020020D00', '0004001020023100', '000400102002C800', '000400102002C900', '000400102002CA00', '000400102002CB00', '0004003000008202', '0004003000008302', '0004003000008402', '0004003000008602', '0004003000008702', '0004003000008D02', '0004003000008E02', '0004003000009502', '000400300000BC02', '000400300000C002', '000400300000C102', '000400300000C302', '000400300000C402', '000400300000C602', '0004003020008802', '000400302000C003', '0004009B00012202', '000400DB00017202', '000400DB20016202'] " use your CIA manager and go through the installed CIAs on your NAND. Whenever you get to a title ID to delete, uninstall it. FBI works well for this.
    9. Use the home button and close your CIA manager. Note: If you get "An error has occurred" just restart your emuNAND. This has happened to me.
    10. You have finished step D.
    Optional: Step E: Restoring lost system titles
    1. Go to yls8.mtheall.com/reports.php and find the title IDs for the lost titles make sure they are for your new region. Some titles may not be under New3DS reports, in this case, find the latest Old3DS report.
    2. Download the missing titles with 3DSNUS and pack them as CIAs.
    3. Move the CIAs to your SD card and install to emuNAND with your CIA manager.
    4. They may not show at first, restart your emuNAND.
    5. You have finished step E.
    Optional: Step F: Something F'ed up and now you need to restore your emuNAND.
    1. Power off your device and boot to sysNAND.
    2. Use your preferred exploit to enter the Homebrew Launcher and run Decrypt9WIP.
    3. Go to "EmuNAND Options" -> "EmuNAND Restore".
    4. Follow the safety check shown.
    5. Select the same file name you used in Step A.
    6. Grab a snack and wait 10 - 20 minutes.
    7. When finished, exit and reboot.
    8. All changes you've made in this tutorial have been reverted.
    9. You have finished step F.

    I don't get why an N3DS XL/LL won't work. They're not that different compared to a N3DS when it comes to firmware right?:s Also additional advice: You can also back up your emunand much faster by using emunandtool on your pc & extract the emunand if you're impatient! saves SD space & time transfering it to pc later.(decrypt9 is handy for this since it let's you remove your SD by pressing select)

    Btw isn't also handy have a clean unlinked emunand, in case you want to make an new nnid for that region?:o

    Yes, I might change the entire tutorial to just region changing any emunand in general

    Follow the guide the same way it is now and ignore the Japanese n3ds requirement.

    I find it funny that I couldn't find this guide when I needed it but a day later it pops up. I would like to add that if your JPN N3DS is under 9.2 (Mine is 9.1), there is no need to update sysnand to 9.2. Unintentionally, I ended up with a 9.1 sysnand and a 9.2 emunand and everything works perfectly fine.

    Couldn't have been more straightforward.

    Jumped from 9.1 JP emunand to 9.5 emunand after installing the appropriate CIAs + injecting the right file. Looks like I'm all set.

    Guys I am a bit lost. I am currently in step Step D: Cleaning up - but Where do I find the installed CIAs on my system ? Is Cia manager a specific manager? I have Title Manager which I used to install the CIA files for the update to USA, but if I get in it does not show any installed cia files, how do I remove them?

    --edit--

    Nvm I found it w/ FBI


    ---edit2---

    This worked incredibly well. Thank you for this amazing and SIMPLE guide, others I had seen just made me want to not even read the tutorial, but this is perfect,thank you

    ---edit3----

    So far all is good, just encountered an issue. Renaming a folder crashes the 3ds...

    Hmm, I fail to install the update cias for my target region with FBI 1.4.17: first it installs some titles, then some titles obviously already exist, so I'm asked to confirm overwrite, but for some titles it fails to delete the old one (when overwriting) and finally after some titles it goes into some out_of_resource error from which it only recovers when I reboot (however after some titles are overwritten reboot of course does not work anymore and I can't complete the installation.)
    The out_of_resource error is for sure not caused by the sd-card. Some 28GB are free and in emunand some 630MBs are free when I start the update.
    Any ideas?

    Had more luck with this tutorial:
    I guess in essence the biggest difference is that it just uses sysupdater instead of FBI to install the update cias and does not need 3dsnus post-installation of missing titles as one merges the titles from previous update versions.
    Not sure about the need to format your system via system settings after update as described here, at least it's not needed in the youtube tutorial but that could be due to the fact that in the youtube tutorial one should delete some titles from emunand already before updating.
    Anyway, my US emunand is finally a EUR one :)

    You would need the right list of titles to delete, but other than that it's more or less the same process.

    You won't have eShop. No, that three EmuNAND switching trick won't work.
    Any game that uses NNID for online will also likely not work online.
