title: "Uninstall CFW"
---

{% include toc title="Inhoudsopgave" %}

### Verplicht te lezen

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 should be manually removed before starting this process by using the Data Management section of the System Settings. Gebruik een [save manager](https://github.com/FlagBrew/Checkpoint/releases/latest) om de saves van deze niet-gesigneerde (illegale) games te back-uppen.

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.
{: .notice--warning}

Merk op dat als je andere payload bestanden dan `GodMode9.firm` in de `/luma/payloads/` map op je SD-kaart hebt, je bij het ingedrukt houden van (Start) bij het opstarten een "chainloader menu" opent die je kan navigeren met de D-Pad en met de (A) knop "GodMode9" kaHin selecteren. Dit geld voor al deze instructies. 

### Wat je nodig hebt

* De nieuwste versie van [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest)
* De nieuwste versie van [GodMode9](https://github.com/d0k3/GodMode9/releases/latest)
* De nieuwste versie van [DSiWare Uninstaller](https://github.com/MechanicalDragon0687/DSiWare-Uninstaller/releases/latest)
* [safety_test.gm9]({{ base_path }}/gm9_scripts/safety_test.gm9)

### Instructies

#### Deel I - Voorbereiding
1. Schakel je 3DS uit
1. Plaats je SD kaart in je computer
1. Kopieer `boot.firm` en `boot.3dsx` van de Luma3DS `.zip` naar de hoofdmap van je SD-kaart
1. Kopieer `GodMode9.firm` van de GodMode9 `.zip` naar de `/luma/payloads/` map op je SD-kaart
1. Copy the `gm9` folder from the GodMode9 `.zip` to the root of your SD card
1. Copy `DSiWareUninstaller.3dsx` to the `/3ds/` folder on your SD card
1. Copy `safety_test.gm9` to the `/gm9/scripts/` folder on your SD card
1. Stop je SD kaart terug in je 3DS

#### 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. Zet je 3DS aan
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. Schakel je 3DS uit

##### DS Download Play Test
1. Zet je 3DS aan
1. Start de Download Play applicatie (![]({{ "/images/download-play-icon.png" | absolute_url }}){: height="24px" width="24px"})
1. Selecteer "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. Schakel je 3DS uit

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.
{: .notice--warning}

#### Section III - Safety Test
The purpose of this section is to verify that the console will boot and that critical system functions, like System Settings and the keyboard, will work once CFW is uninstalled. **If you skip this section, you may BRICK your device!**

1. Launch the System Settings Application
	+ If the console crashes at this point, the test has failed
1. Selecteer "Other Settings"
1. Selecteer "Profile"
1. Selecteer "User Name"
1. If you are able to enter a new user name, the test was successful
	+ If the keyboard does not appear, the screen freezes, or the console crashes, the test has failed
1. Schakel je 3DS uit

Als je NIET opstart in het normale 3DS HOME Menu, of System Setting / je toetsenbord is niet toegankelijk, **ga NIET verder met deze instructies**! Join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask (in English) for someone there to assist you.
