Before starting this guide, we will see if custom firmware is already installed and check the current system version of your device.

#### Sección I - Verificación de CFW

1. Apaga tu consola
1. Mantén pulsado el botón (Select)
1. Enciende la consola mientras mantienes presionado (Select)
1. If you do not see an unusual menu (e.g. "Luma3DS Configuration"), you may proceed to the next section

If you see an unusual menu, STOP - you already have custom firmware! Continue from [here](checking-for-cfw#what-to-do-next).
{: .notice--warning}

#### Section II - System Version Check

1. Ve a Configuración de la Consola
1. Your system version will be displayed on the bottom right of the top screen (e.g. "Ver. 11.15.0-47U")

#### Section III - Select a Method

Use the version table below to select a method. A few things to note:
  + The version table below is *inclusive*. For example, "from 11.4.0 to 11.14.0" includes 11.4.0, 11.14.0, and all versions in between.
  + Software versions do not work the same as decimals. Versions 11.10.0 and above are newer than 11.3.0, and are therefore not compatible with Soundhax.
  + The number and letter after the system version are not important.
  + No matter the method you follow, the end result is the same (boot9strap+Luma3DS custom firmware setup on the latest firmware).
