<summary><em>Technical Details (optional)</em></summary>

In order to exploit the SAFE_MODE firmware of our system, we need to inject an exploited WiFi profile.

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 the exploited WiFi profile into your connections list.

Once the WiFi profile has been injected, we will use SAFE_MODE, which is a recovery feature present on all 3DS consoles, to activate the exploited WiFi profile.

For a more technical explanation, see the following links for information on the kartdlphax and unSAFE_MODE exploits: [kartdlphax](https://github.com/PabloMK7/kartdlphax), [unSAFE_MODE](https://github.com/zoogie/unSAFE_MODE/).

### Compatibility Notes

Para seguir estas instrucciones, necesitarás lo siguiente:

- Una segunda 3DS con custom firmware (la **3DS de origen**) que sea de la misma región que la 3DS que estás intentando modificar (la **3DS de destino**)
    - The consoles must be USA, JPN, or EUR region consoles
    - The source 3DS can be [region changed](region-changing) to match the target 3DS if necessary
- Una copia física o digital de Mario Kart 7 de la misma región que ambas consolas
- An SD card for both consoles

### Qué necesitas

* The latest release of [kartdlphax](https://github.com/PabloMK7/kartdlphax/releases/latest) (`plugin.3gx`)
* The latest release of [SafeB9SInstaller](https://github.com/d0k3/SafeB9SInstaller/releases/download/v0.0.7/SafeB9SInstaller-20170605-122940.zip) (direct download)
* The latest release of [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest) (the Luma3DS `.zip` file)
* The latest release of [unSAFE_MODE](https://github.com/zoogie/unSAFE_MODE/releases/latest) (the RELEASE `.zip` file)

#### Section I - Hardware Button Check (target 3DS)

If the camera does not open, you cannot follow this method. If this is the case, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.

#### Section II - 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. Inserta la tarjeta SD de la **3DS de origen** en tu computadora
1. Copy `boot.firm` from the Luma3DS `.zip` to the root of the **source 3DS**'s SD card, replacing any existing file
    + La raíz de tu tarjeta SD se refiere al primer directorio de la tarjeta, donde puedes ver la carpeta Nintendo 3DS pero no estás dentro de ella
1. Copia el archivo `plugin.3gx` de kartdlphax al siguiente directorio en la tarjeta SD de la **3DS de origen**, dependiendo de la **región de tu copia de Mario Kart 7**:
    - USA: `luma/plugins/0004000000030800`
    - EUR: `luma/plugins/0004000000030700`
    - JPN: `luma/plugins/0004000000030600`
    - Crea las carpetas `plugins` y `00040000...` si no existen
1. Saca la tarjeta SD de la computadora y ponla en la **3DS de origen**

#### Section III - Prep Work (target 3DS)

In this section, you will copy the files needed to trigger the unSAFE_MODE exploit onto your target 3DS (the 3DS that you are trying to modify)'s SD card.

1. Inserta la tarjeta SD de la **3DS de destino** en tu computadora
1. Copy `boot.firm` and `boot.3dsx` from the Luma3DS `.zip` to the root of the **target 3DS's** SD card
1. Crea una carpeta llamada `boot9strap` en la raíz de tu tarjeta SD
1. Copy `boot9strap.firm` and `boot9strap.firm.sha` from the RELEASE `.zip` to the `/boot9strap/` folder on your SD card
1. Copia `SafeB9SInstaller.bin` desde el `.zip` de SafeB9SInstaller a la raíz de tu tarjeta SD
1. Copy `usm.bin` from the RELEASE `.zip` to the root of your SD card
1. Create a folder called `3ds` on the root of your SD card
1. Copy `slotTool.3dsx` from the `slotTool` folder inside the RELEASE `.zip` to the `/3ds/` folder on your SD card
1. Saca la tarjeta SD de la computadora y ponla en la **3DS de destino**

#### Section IV - kartdlphax

In this section, you will use Download Play to transfer the exploit data from the source 3DS to the target 3DS, which can be used to overwrite your Wi-Fi slots with hacked data. Your Wi-Fi connection settings will be temporarily overwritten while the exploit is active.

1. Enciende la **3DS de origen**
    - Si te le pide que configures Luma3DS, pulsa START para guardar la configuración
1. Once in the HOME Menu, press (Left Shoulder) + (Down D-Pad) + (Select) to bring up the Rosalina menu
1. Selecciona "Enable plugin loader"
1. Presiona (B) para salir del menú de Rosalina
1. Inicia Mario Kart 7
    - Asegúrate de que la conectividad inalámbrica está habilitada
1. Navigate to `Local Multiplayer`. A menu should pop up
    - If the screen freezes, hold the power button for fifteen seconds to force power off your console, then try again
    - If you have launched kartdlphax previously, the last selected settings will be loaded. If they are correct, select `Use settings` and skip the next 3 steps. If they are incorrect, select `Change settings` and proceed.
1. Select your **target 3DS** console type (Old 3DS family or New 3DS family)
1. Select the following exploit type depending on your system version:
    - 11.16.0: select `xPloitInjector (11.16)`
    - 11.17.0: select `xPloitInjector (11.17)`
1. A confirmation menu will show up. If the settings shown on the top screen are correct, select `Use settings`
    - If the settings are not correct, press `Change settings` and modify them accordingly
1. Select `Create Group`
    - If the source 3DS freezes at this point and you are using a cartridge, try [installing the cartridge to the system](dumping-titles-and-game-cartridges#installing-a-game-cartridge-directly-to-the-system)
1. Enciende la **3DS de destino**
    - Asegúrate de que la conectividad inalámbrica está habilitada
1. En la **3DS de destino**, abre la aplicación de Modo Descarga (![]({{ "/images/download-play-icon.png" | absolute_url }}){: height="24px" width="24px"}), luego selecciona "Nintendo 3DS"
1. Entra al grupo creado por la **3DS de origen**
1. Selecciona "Start" en la **3DS de origen** una vez detectada la **3DS de destino**
1. Once multiplayer has loaded, navigate to `Grand Prix` -> `50cc` -> (any driver) -> `Mushroom Cup` -> `OK`
1. Espera un rato (se debería mostrar un porcentaje en la **3DS de origen**)
1. If the exploit was successful, the **target 3DS** will have booted into the 3DS ROP xPloit Injector
    - If the exploit was not successful, power off the **source 3DS** and **target 3DS** and start again from the beginning of `Section III - kartdlphax`
1. Press (X) to inject unSAFE_MODE
1. If the injection was successful, the screen will turn green and the **target 3DS** will automatically power off
    + If the screen turns red, power off the target 3DS and start again from the beginning of `Section III - kartdlphax`. If this doesn't work, ask for help at [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp))

You will **not** need to use your **source 3DS** to complete any further steps on this guide. Any further steps should only be completed on the **target 3DS**.
