### Lectura requerida

This will completely remove CFW from your device, including boot9strap and Luma3DS, for the purpose of restoring the device to stock.

This is never the solution to fix any issues you may be encountering with your CFW installation. A better idea would be to ask (in English) for help at [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp).
{: .notice--danger}

Cualquier juego sin firmar (ilegítimo) se volverá inutilizable y debe ser eliminado manualmente antes de comenzar este proceso yendo a la sección Gestión de datos en la Configuración de la consola. Utiliza un [gestor de datos de guardado](https://github.com/FlagBrew/Checkpoint/releases/latest) para respaldar los datos de guardado de cualquier juego sin firmar (ilegítimo) que te sea de importancia conservar.

If you have modified critical system software (such as editing the home menu, unbanning your console, region changing, etc.), uninstalling CFW WILL BRICK your device! Ensure that you follow all sections of this page.
{: .notice--danger}

These instructions will only work on devices with a Luma3DS version of 8.0 or higher. If you have an older version of Luma, you must upgrade your setup before following these instructions. Follow [this page](checking-for-cfw) to find your upgrade instructions.

##### DS Connection Settings Test
1. Enciende tu consola
1. Launch the System Settings Application
1. Navigate to `Internet Settings` -> `Nintendo DS Connection Settings`, then click OK

If either of these tests has failed, DS mode, DS Download Play, and/or DS Connection Settings may be inaccessible once CFW is uninstalled! You should [fix DS mode](troubleshooting#dsi--ds-functionality-is-broken-or-has-been-replaced-with-flipnote-studio) before continuing.
