### 必讀事項

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}

您將無法遊玩任何已安裝且未簽證(盜版)的遊戲，請在開始本頁之前至系統設定的資料管理中將它們刪除。 建議您先使用[存檔管理器](https://github.com/FlagBrew/Checkpoint/releases/latest)將您較在乎的遊戲存檔備份起來。

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

請注意，如果您在 SD 卡中的 `/luma/payloads/` 資料夾中放有除了 `GodMode9.firm` 的 payload 檔案，在開機時按住『Start』鍵將會顯示一個『加載選單』，從那裏您得透過方向鍵及按鈕『A』選擇『GodMode9』。 

### 必備項目

* The latest release of [GodMode9](https://github.com/d0k3/GodMode9/releases/latest)
* The latest release of [DSiWare Uninstaller](https://github.com/MechanicalDragon0687/DSiWare-Uninstaller/releases/latest)
* [safety_test.gm9]({{ base_path }}/gm9_scripts/safety_test.gm9)

### 操作說明

#### 第一節 — 準備工作
1. 關閉您的主機
1. 將 SD 卡插入至電腦中
1. 解壓 GodMode9 `.zip` 中的 `GodMode9.firm` 檔案到 SD 卡的 `/luma/payloads/` 資料夾中
1. 解壓 GodMode9 `.zip` 中的 `gm9` 資料夾到 SD 卡的根目錄底下
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. 將 SD 卡插回主機中

#### 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. 啟動您的主機
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. 關閉您的主機

##### DS Download Play Test
1. 啟動您的主機
1. 啟動『下載通信(Download Play)』程式 (![]({{ "/images/download-play-icon.png" | absolute_url }}){: height="24px" width="24px"})
1. 選擇『任天堂 DS (Nintendo DS)』
1. 如果您的裝置可正常進入 DS『下載通信(Download Play)』程式則代表測試成功
  + If your console displays the Japanese version of Flipnote Studio, a black screen, or an error message, the test has failed
1. 關閉您的主機

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-after-completing-the-guide) before continuing.

  + If you do not boot into the regular 3DS home menu (black screen, error screen, etc.), uninstalling CFW **WILL BRICK YOUR DEVICE!** 
1. Launch the System Settings Application
	+ If the console crashes at this point, the test has failed
1. Select "Other Settings"
1. Select "Profile"
1. Select "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. 關閉您的主機

If you do NOT boot into the regular 3DS Home Menu, or System Settings / your keyboard is inaccessible, **DO NOT continue with these instructions**! Join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask (in English) for someone there to assist you.
