### Lectura requerida

The file `boot.firm` is what is launched by boot9strap itself after it finishes loading off of NAND. In this case, we are using Luma3DS by [LumaTeam](https://github.com/LumaTeam/) to patch the device, allowing it to run homebrew software.

On this page, we will make critical system file backups and install the following homebrew programs:

+  **FBI** *(installs CIA formatted applications)*
+ **Anemone3DS** *(instala temas personalizados)*
+ **Checkpoint** *(permite respaldar y restaurar archivos de guardado de juegos de 3DS y DS)*
+  **Universal-Updater** *(a homebrew app store for downloading homebrew from the 3DS over Wi-Fi)*
+  **GodMode9** *(herramienta multipropósito que puede realizar funciones sobre la NAND y cartridges)*
+ **Homebrew Launcher Loader** *(inicia el Homebrew Launcher)*

It is not recommended to skip downloading any of these applications, as many of them will be used later on this page. At the end of this page, your SD card will be cleaned up by removing unnecessary installation files.

### Compatibility Notes

If your **New 3DS** was on version 2.1.0 before following this guide, you should [restore your NAND backup](godmode9-usage#restoring-a-nand-backup) before continuing. This likely doesn't apply to you unless you were following this guide in 2017.
{: .notice--warning}

If your previous CFW setup was EmuNAND-based and you wish to move the contents of your EmuNAND/RedNAND to SysNAND, follow [Move EmuNAND](move-emunand) before following this page. If you don't know what an EmuNAND is, this doesn't apply to you.

### Instrucciones

#### Sección I - Preparativos

In this section, you will copy the files necessary to follow the rest of the instructions on this page.

1. Apaga tu consola
1. Inserta tu tarjeta SD en tu computadora
1. Crea una carpeta llamada `cias` en la raíz de tu tarjeta SD, si aún no existe
1. Copy all of the CIA files (`Anemone3DS.cia`, `Checkpoint.cia`, `FBI.cia`, `Homebrew_Launcher.cia`, and `Universal-Updater.cia`) to the `/cias/` folder on your SD card
1. Crea una carpeta llamada `3ds` en la raíz de tu tarjeta SD, si aún no existe
    + Esta carpeta almacena aplicaciones homebrew y datos relacionados; es distinta de la carpeta `Nintendo 3DS` que genera la consola automáticamente
1. Copia `FBI.3dsx` a la carpeta `/3ds/` de tu tarjeta SD
1. Crea una carpeta llamada `payloads` dentro de la carpeta `luma` en tu tarjeta SD si aún no existe
1. Copia el archivo `GodMode9.firm` desde el `.zip` de GodMode9 a la carpeta `/luma/payloads/` en tu tarjeta SD
1. Copia la carpeta `gm9`contenida en el `.zip`de GodMode9 al directorio raíz de tu tarjeta SD
1. Reinserta tu tarjeta SD en tu consola
1. Enciende tu consola

The screenshots below indicate the minimum SD card layout that is required to follow this page. You may have extra files or folders on your SD card, depending on your previous setup or the method that you followed.

#### Section II - CFW Check

As an additional safety measure, we will perform an additional check for custom firmware. If custom firmware is not installed by this point for any reason, the next section may render your console unable to be hacked without external hardware.

1. Apaga tu consola
1. Mantén pulsado el botón (Select)
1. Enciende la consola mientras mantienes presionado (Select)
1. If the check was successful, your device should have booted into the Luma3DS configuration menu
1. Presiona (Start) para guardar y reiniciar
1. Apaga tu consola

If you do NOT boot into the Luma3DS configuration menu, custom firmware was not installed on your device. Join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.

#### Section III - Updating the System

In this section, you will update your system to the latest version, which is safe to do with custom firmware.

{% include_relative include/sysupdate.txt cfw="true" %}

In this section, you will temporarily replace Download Play with Homebrew Launcher (which we need to launch FBI). Download Play will automatically go back to normal once you reboot your device.

{% include_relative include/launch-hbl-dlp.txt %}

#### Section V - RTC and DSP Setup

In this section, you will sync your 3DS internal clock with the actual time and dump the sound firmware (which is necesssary for some homebrew software to use sound properly).

1. Apaga tu consola
1. Presiona y mantén el botón (Start), y mientras lo mantienes presionado, enciende tu consola. Esto abrirá GodMode9
  + Si GodMode9 no inicia, asegúrate de que `GodMode9.firm` esté en `/luma/payloads/` y que `payloads` esté escrito correctamente
1. Si se te pide crear copias de seguridad de archivos esenciales, presiona (A) para hacerlo y luego presiona (A) para continuar una vez que haya terminado

  + Estos respaldos podrán prevenir que se inutilice la consola y/o ayudarte a recuperar archivos de la memoria de tu consola si algo sale mal en el futuro
1. Delete `<date>_<serialnumber>_sysnand_##.bin` and `<date>_<serialnumber>_sysnand_##.bin.sha` from the `/gm9/out/` folder on your SD card after copying it

### Information and Notes

{% capture notice-6 %}
Here are some key combos that you should know:

- Holding (Select) on boot will launch the Luma3DS configuration menu.
- Holding (Start) on boot will launch GodMode9, or if you have multiple payloads in `/luma/payloads/`, the Luma3DS chainloader.
- By default, pressing (Left Shoulder) + (Down D-Pad) + (Select) while in 3DS mode will open the Rosalina menu, where you can check system information, take screenshots, enable cheats, and more. This can be changed from the Rosalina menu.
- Holding (Start) + (Select) + (X) on boot will make the notification LED show a color for debug purposes. See the [changelog](https://github.com/SciresM/boot9strap/releases/tag/1.4) for a list.
