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

This method of using Seedminer for further exploitation uses your `movable.sed` file to decrypt any DSiWare title for the purposes of injecting an exploitable DSiWare title into the DS Internet Settings application.

This is a currently working implementation of the "FIRM partitions known-plaintext" exploit detailed [here](https://www.3dbrew.org/wiki/3DS_System_Flaws).

### Qué necesitas

* Tu archivo `movable.sed` proveniente de haber completado [Seedminer](seedminer)
* The latest release of [Frogminer_save](https://github.com/zoogie/Frogminer/releases/latest) (`Frogminer_save.zip`)
* The latest release of [b9sTool](https://github.com/zoogie/b9sTool/releases/latest) (`boot.nds`)
* The latest release of [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest) (the Luma3DS `.zip` file)

#### Sección I - Verificación de CFW

As an additional safety measure, we will perform an additional check for custom firmware. This is because using this method when custom firmware is already installed has a risk of bricking the console (rendering it unusable without recovery methods like [ntrboot](ntrboot)).

1. Apaga tu consola
1. Mantén pulsado el botón (Select)
1. Enciende la consola mientras mantienes presionado (Select)
1. If the check was successful, you will boot to the HOME Menu and you may proceed with this guide
1. Apaga tu consola

If you see a configuration menu or the console immediately powers off, you already have CFW, and continuing with these instructions may BRICK your device! Sigue la sección de [Comprobación de CFW](checking-for-cfw) para actualizar tu CFW existente.

  + If you see the Luma Configuration screen, power off your device and continue to the next section

#### Section VI - Luma3DS Configuration

1. Press and hold (Select), and while holding (Select), power on your device. This will launch Luma3DS configuration
