### Required Reading

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}

Any unsigned (illegitimate) games will be rendered unusable and will be removed during this process. Use a [save manager](https://github.com/FlagBrew/Checkpoint/releases/latest) to back up any saves for these unsigned (illegitimate) games you care about.

If you have modified critical system software (such as installing a custom HOME Menu CIA, 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.
{: .notice--warning}

Note que se você tem outros arquivos de payload diferentes do `GodMode9.firm` na pasta `/luma/payloads/` do seu cartão SD, segure (Start) durante a inicialização para exibir um "menu de chainloader" onde você terá que utilizar os botões direcionais e o botão (A) para selecionar "GodMode9" para estas instruções. 

### What You Need

#### Section II - DS Mode Tests
The purpose of this section is to check whether built-in DS mode applications will continue to work once CFW is uninstalled. If you skip this section, DS mode or its functions may be inaccessible until CFW is reinstalled.

##### DS Connection Settings Test
1. Ligue o seu dispositivo
1. Launch the System Settings Application
1. Navigate to `Internet Settings` -> `Nintendo DS Connection Settings`, then click OK
1. You should boot into the Nintendo DS Connection Setup menu
  + If your console displays the Japanese version of Flipnote Studio, a black screen, or an error message, the test has failed
1. Desligue seu dispositivo

##### DS Download Play Test
1. Ligue o seu dispositivo
1. Launch the Download Play application (![]({{ "/images/download-play-icon.png" | absolute_url }}){: height="24px" width="24px"})
1. Select "Nintendo DS"
1. If your device loads into a "Download software via DS Download Play" menu, the test was successful
  + If your console displays the Japanese version of Flipnote Studio, a black screen, or an error message, the test has failed
1. Desligue seu dispositivo

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.
