Technische Details (optional)

In order to install custom firmware on our console, we need to get Homebrew Launcher access.

To accomplish this, we can use the Download Play functionality of the game Mario Kart 7, using a 3DS with custom firmware already installed along with a custom game plugin.

This custom plugin will send a hacked payload to an unhacked console, which then exploits the system in order to inject menuhax67, which will allow us to get Homebrew Launcher access.

Once we have Homebrew Launcher access, we can run nimdsphax to install boot9strap.

See here for information about kartdlphax, here for information about menuhax67, and here for information about nimdsphax.

In order to follow these instructions, you will need the following:

  • A second 3DS with custom firmware (the source 3DS) that is the same region as the 3DS you are trying to modify (the target 3DS)
    • The consoles must be USA, JPN, or EUR region consoles

Was du brauchst

Section I - Prep Work (source 3DS)

In this section, you will set up your source 3DS (the 3DS with custom firmware) for delivery of the exploit data to the target 3DS.

  1. Insert the SD card of your source 3DS in your computer
  2. Copy boot.firm from the Luma3DS .zip to the root of the source 3DS’s SD card, replacing any existing file
    • The root of the SD card refers to the initial directory on your SD card where you can see the Nintendo 3DS folder, but are not inside of it
  3. Copy kartdlphax’s plugin.3gx to the following directory on the source 3DS’s SD card, depending on the region of your copy of Mario Kart 7:
    • USA: luma/plugins/0004000000030800
    • EUR: luma/plugins/0004000000030700
    • JPN: luma/plugins/0004000000030600
    • Create the plugins and 00040000... folders if they do not already exist
  4. Eject the SD card and put it in the source 3DS

Section II - Prep Work (target 3DS)

In this section, you will set up the files that the target 3DS will need to install custom firmware.

  1. Insert the SD card of your target 3DS in your computer
  2. Copy boot.firm and boot.3dsx from the Luma3DS .zip to the root of the target 3DS’s SD card
  3. Erstelle einen Ordner namens boot9strap im Stammverzeichnis deiner SD-Karte
  4. Kopiere boot9strap.firm und boot9strap.firm.sha aus der boot9strap .zip in den /boot9strap/-Ordner auf deiner SD-Karte
  5. Copy SafeB9SInstaller.bin from the SafeB9SInstaller .zip to the root of your SD card
  6. Erstelle einen Ordner namens 3ds im Stammverzeichnis deiner SD-Karte falls er noch nicht existiert
    • This folder stores homebrew applications and data; it is different from the Nintendo 3DS folder that the console automatically generates
  7. Copy the nimdsphax folder from the nimdsphax .zip to the /3ds/ folder on your SD card
  8. Copy menuhax67_installer.3dsx from the menuhax .zip to the /3ds/ folder on your SD card
  9. Copy Launcher.dat from the folder for your model and region inside the menuhax .zip to the root of your SD card
  10. Eject the SD card and put it in the target 3DS
