emuNAND Setup Edit
- Switch off the 3DS and mount the SD card in your computer. Open the 'Nintendo 3DS' folder, open the folder inside it, then open again the one inside that one. You should see the 'extdata' folder. Create another one inside the folder containing 'extdata' and rename it 'dbs'. If it already exists, and there is two files ('titles.db' and 'import.db') you do not need to do anything. If they don't exist, you need to create them from an empty file.
- Download the latest version of Gateway Ultra and put the 'Launcher.dat' file in the root of the SD card.
- Put the SD card in the 3DS and boot it. Go into System - Data management - Software. It'll ask you to reset or repair the Software management information on the SD card, allow it to do so. Don't do it if you already had those files.
- Open the web browser and go to http://go.gateway-3ds.com/.
- Navigate to 'Backup System Nand' and select it. When it finishes, switch off the 3DS and put the SD back in the computer, then backup all of the contents, especially the 'Nintendo 3DS' folder and the 'Nand.bin' file. The latter is your Nand backup, so keep it safe.
- Boot up the 3DS again and go to http://go.gateway-3ds.com/ again. Navigate to 'Format emuNAND' and wait it to finish.
- Turn of the 3DS and restore the SD card backup.
- The emuNAND created with Gateway will work fine on rxTools.
Cubic Ninja Users:
- Do as before until point #5.
- Install Ninjhax following the site's instructions (install Ninjhax 1, the second version will not work).
- Download FBI CIA Installer and put the 3ds folder and FBI.cia in the root of the SD card.
- Setup Pasta CFW following the instructions on the website. Download latest .zip and put the 3ds folder in the SD card.
- Insert Cubic Ninja and start Ninjhax. Open Pasta CFW.
- Once into Pasta, open Ninjhax again and start FBI. Select 'FBI.cia' and make sure that in the top screen it says 'destination: SD' and 'mode: Install CIA'. It will install FBI in your Sysnand.
- Start Gateway Launcher and format emuNAND. Now you can restore the SD backup, except for Nand.bin.
- Download rxTools and Python 2.7.
- Put 'rxtools' folder in the SD card.
- Run 'cdn_firm.py' in the 'Tools' folder.
- Put the generated 'firmware.bin' in the 'rxtools/sys' folder on the SD card.
- Get 'slot0x25KeyX.bin' (from Google, in a certain YouTube video description) and put it in the root of tehe SD card.
- Delete the 'rxtools' folder from the SD card, then follow steps 2-5 above.
- Copy the 'rxtools' folder in the 'ninjhax' folder along with your other homebrew applications.
