Hacking [Guide] Change emuNAND Region

[DarkFlare69]

You don't need it, you only need sysupdater and Decrypt9 now.

So I'm assuming we download a different regions cia files and install them with sysupdater? Or what?

That's basically how it works ^o^

I have changed my emunand region from 9.1J to 9.1U and then updated to 10.4U. Everything works fine except eshop of course but that a SecureInfo_A issue.

@Nazosan and I were working on this a week or so ago. You can't just install 9.1U over 9.1J. Too many things are missing and your emunand will be incomplete causing most of the errors you see(keyboard and things). Here's what you need to do.

1. Get all of the updates for the system region you want to switch to starting from the lowest you can find (4.2) to whatever your emunand is now (9.2). If you are using a N3DS get the O3DS updates up to 8.1 and then get the N3DS updates from 9.0 and up.

2. Merge all of the update cia's into a single folder overwriting older versions with newer versions (add 4.2 cia's to the folder then 4.5 cia's then 5.0 etc..) when you are done there should be around 170 files.

3. Delete all cia's starting with 0004001B, 0004800F, 00048005, 00040130, 00040138, and 00048005. These will prevent the emunand from loading.

4. Place all of these cia's in a folder named updates on the root of your sd card.

5. Use FBI to uninstall the main system titles from your emunand (system settings, mii maker, miiverse, camera, etc...). If you region change before deleting the system titles it will cause your emunand to freeze randomly and block you from entering the system settings app.

6. Use sysupdater in emunand to install all of the cia's in your update folder. When this is done your system will reset.

7. Use decrypt9 or rxtools to inject the SecureInfo_A for your new region into emunand. My system was weird in that I had a SecureInfo_B instead of A so rxtools would not work but decrypt9 did.

8. Congrats!! You have a region changed system. Now format it and update however you like. I updated with a cart to 9.4U first and then updated through system settings to 10.4U.

The eshop will not work unless you had a SecureInfo_A from a system that never connected to the internet.

Were you able to get it working?

Am I missing anything?

1. Download other region CIA firmware files
2. Put them in "updates" on SD Card
3. Go to emuNAND
4. Install them using sysUpdater
5. Emunand region changed?

Is that all? What's decrpyt9 used for?

You need it to inject the SecureInfo_A file from region you are changing to. Read what I posted a couple minutes ago.

Ok, so inject secureinfo_a and then install the appropriate CIAs?

There is a step by step guide three posts up. Read it.

How can I run sysUpdater within emuNAND?
(Preferably without accessing the homebrew launcher, since for some reason I cannot launch it within emuNAND)

Install it as a cia and run it from the home screen. Make sure you are using sysupdater and not safesysupdater. Safesysupdater is for downgrading to 9.2 only.

Can you pm me that CIA? I can't seem to find it anywhere. Thanks!

Update: I can confirm that Bu2d85's method of changing the emunand region actually works!

@Nazosan came up with the idea of merging all of the previous updates. The rest came from searching through the forums.

There's about 150 CIAs on my emuNAND classified as "system" cias. Do I really have to uninstall all those?

No just system menu titles like mii maker, miiverses, camera, etc..

Each system region has different menu titles. If you do not delete the old ones you will have duplicates on you home screen. When I had these duplicates it kept causing my system to freeze. You can find the title ID's at 3dbrew.org.

It doesn't say the names, it says the code.

There's ones called XXXXbuilder, ones called (N/A) and ones called CTR-N-XXXX. So I delete all the CTR-N ones?

 

[Supster131]

Any way to get the eShop working? Even if we have to go through shady means

Not all of the CTR-N ones. There are only about 8 that have to be deleted. The top screen you should see a string of number that look something like 020000200 or 000400e7 (not these exactly, these are made up for demonstration purposes). That string of numbers is the title ID. Every region is different so I can't tell you what they are. You have to look them up.

That's actually why I have been on these forums all day. As far as I can tell there is no way unless you have a SecureInfo_A from a system that was never connected to the internet.

There are some steps in this guide you can try. It did not work for me but it might for you. There is a section specifically for eshop.
