In order to exploit the SAFE_MODE firmware of our system, we need to inject an exploited WiFi profile.

To accomplish this, we can use the Download Play functionality of the game Mario Kart 7, using a 3DS with custom firmware already installed along with a custom game plugin.

This custom plugin will send a hacked payload to an unhacked console, which then exploits the system in order to inject the exploited WiFi profile into your connections list.

Once the WiFi profile has been injected, we will use SAFE_MODE, which is a recovery feature present on all 3DS consoles, to activate the exploited WiFi profile.

For a more technical explanation, see the following links for information on the kartdlphax and unSAFE_MODE exploits: [kartdlphax](https://github.com/PabloMK7/kartdlphax), [unSAFE_MODE](https://github.com/zoogie/unSAFE_MODE/).

### Compatibility Notes

如果你想通過此方法安裝自製韌體，則你需要：

- A second 3DS with custom firmware (the **source 3DS**) that is the same region as the 3DS you are trying to modify (the **target 3DS**)
  - The consoles must be USA, JPN, or EUR region consoles
- 一份與兩台主機同區的馬利歐賽車 7 (實體或數位版皆可)
- 兩張 SD 卡

If the (Right/Left Shoulder), (D-Pad Up), or (A) buttons on the **target 3DS** do not work, you will not be able to follow these instructions. For further assistance with this matter, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.

#### 第一步 – 準備工作(目標 3DS)

In this section, you will set up your source 3DS (the 3DS with custom firmware) for delivery of the exploit data to the target 3DS.

1. Insert the SD card of your **source 3DS** in your computer
1. Copy Luma 3GX Loader Edition's `boot.firm` to the root of the **source 3DS**'s SD card, replacing any existing file
  + 「SD 卡的根目錄」指的是你的 SD 卡含有 Nintendo 3DS 資料夾的目錄，而非該資料夾內部
1. Copy kartdlphax's `plugin.3gx` to the following directory on the **source 3DS**'s SD card, depending on the **region of your copy of Mario Kart 7**:
  - 美版： `luma/plugins/0004000000030800`
  - 歐版： `luma/plugins/0004000000030700`
  - 日版： `luma/plugins/0004000000030600`
  - Create the `plugins` and `00040000...` folders if they do not already exist
1. Eject the SD card and put it in the **source 3DS**

#### 第二步 – 準備工作(目標 3DS)

In this section, you will copy the files needed to trigger the unSAFE_MODE exploit onto your target 3DS (the 3DS that you are trying to modify)'s SD card.

1. Insert the SD card of your **target 3DS** in your computer
1. 解壓 Luma3DS `.zip` 內的 `boot.firm` 及 `boot.3dsx` 到 SD 卡的根目錄底下
1. 在 SD 卡的根目錄底下建立一個新的資料夾 `boot9strap`
1. 解壓 boot9strap `.zip` 的 `boot9strap.firm` 及 `boot9strap.firm.sha` 檔案至 SD 卡的 `/boot9strap/` 資料夾中
1. 將 SafeB9SInstaller `.zip` 中的 `SafeB9SInstaller.bin` 複製到 SD 卡的根目錄
1. Copy `usm.bin` from the unSAFE_MODE `.zip` to the root of your SD card
1. Create a folder called `3ds` on the root of your SD card
1. Copy the `slotTool` folder from the unSAFE_MODE `.zip` to the `3ds` folder on your SD card
1. Eject the SD card and put it in the **target 3DS**

#### 第三節 — kartdlphax

In this section, you will use Download Play to transfer the exploit data from the source 3DS to the target 3DS, which can be used to overwrite your Wi-Fi slots with hacked data. Your Wi-Fi connection settings will be temporarily overwritten while the exploit is active.

1. Power on the **source 3DS**
  - If you are prompted to set up Luma3DS, just press START to save the configuration
1. Once in the HOME Menu, press (Left Shoulder) + (Down D-Pad) + (Select) to bring up the Rosalina menu
1. 選擇『Enable plugin loader』
1. 按『B』退出 Rosalina 選單
1. 開啟瑪莉歐賽車 7
  - 請確保您已經開啟了無線連接
1. Navigate to `Local Multiplayer`. A menu should pop up
  - If the screen freezes, hold the power button for fifteen seconds to force power off your device, then try again
  - If you have launched kartdlphax previously, the last selected settings will be loaded. If they are correct, select `Use settings` and skip the next 3 steps. If they are incorrect, select `Change settings` and proceed.
1. Select your **target 3DS** device type (Old 3DS family or New 3DS family)
1. Select the exploit type `3DS ROP xPloit Injector`
1. A confirmation menu will show up. If the settings shown on the top screen are correct, select `Use settings`
  - If the settings are not correct, press `Change settings` and modify them accordingly
1. Select `Create Group`
  - If the source 3DS freezes at this point and you are using a cartridge, try [installing the cartridge to the system](dumping-titles-and-game-cartridges#installing-a-game-cartridge-directly-to-the-system)
1. 將 **3DS 目標機** 開機
  - 請確保您已經開啟了無線連接
1. On the **target 3DS**, open the Download Play application (![]({{ "/images/download-play-icon.png" | absolute_url }}){: height="24px" width="24px"}), then select "Nintendo 3DS"
1. Join the group created by the **source 3DS**
1. Select "Start" on the **source 3DS** once it has detected the **target 3DS**
1. Once multiplayer has loaded, navigate to `Grand Prix` -> `50cc` -> (any driver) -> `Mushroom Cup` -> `OK`
1. Wait a while (a percentage should be displayed on the **source 3DS**)
1. If the exploit was successful, the **target 3DS** will have booted into the 3DS ROP xPloit Injector
  - If the exploit was not successful, power off the **source 3DS** and **target 3DS** and start again from the beginning of `Section III - kartdlphax`
1. Press (X) to inject unSAFE_MODE
1. If the injection was successful, the screen will turn green and the **target 3DS** will automatically power off
  + If the screen turns red, power off the target 3DS and start again from the beginning of `Section III - kartdlphax`. If this doesn't work, ask for help at [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp))

You will **not** need to use your **source 3DS** to complete any further steps on this guide. Any further steps should only be completed on the **target 3DS**.

#### Section IV - unSAFE_MODE

In this section, you will enter Safe Mode (a feature available on all 3DS family devices) and navigate to a menu where unSAFE_MODE will be triggered, which will launch you into the boot9strap (custom firmware) installer.

1. With your device still powered off, hold the following buttons: (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A), and while holding these buttons together, power on your device
  + Keep holding the buttons until the device boots into Safe Mode (a "system update" menu)
  + If you're unable to get into Safe Mode after multiple attempts, one of your buttons may be failing or broken. If this is the case, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.
1. 按下『OK』以允許更新
  + 此步驟將不會進行任何更新， 這只是觸發漏洞的一部分。
1. 按下「I accept(我同意/同意します)」鍵以接受聲明條款
1. The update will eventually fail, with the error code `003-1099`. 這也是觸發漏洞的一部分
1. 當系統提示您『你想要配置網路設置嗎? (Would you like to configure Internet settings?)』時，點選『Yes』
1. On the following menu, navigate to `Connection 1` -> `Change Settings` -> `Next Page (right arrow)` -> `Proxy Settings` -> `Detailed Setup` ([image](/images/screenshots/bb3/safemode_highlighted.png))
1. 如果一切成功的話，您將自動進入 SafeB9SInstaller

#### Section V - Installing boot9strap

In this section, you will install custom firmware onto your device.

1. 出現提示時，輸入上方螢幕所顯示的按鍵組合以安裝 boot9strap
  + If the top screen is blank, power off your device and re-do Section III
1. 過程結束後，按下『A』重啟主機
1. Your target 3DS should have rebooted into the Luma3DS configuration menu
  + Luma3DS configuration menu are settings for the Luma3DS custom firmware. Many of these settings may be useful for customization or debugging
  + For the purpose of this guide, these settings will be left on default settings
  + If your device shuts down when you try to power it on, ensure that you have copied `boot.firm` from the Luma3DS `.zip` to the root of your SD card
1. 按『Start』鍵以存檔並重新啟動系統

At this point, your console will boot to Luma3DS by default.
  + Luma3DS 不會特別在 HOME 主選單中新增任何特別的東西。 如果你的主機已經啟動到了 HOME 主選單，這代表自製韌體已經在運行了。
  + On the next page, you will install useful homebrew applications to complete your setup.

#### Section VI - Restoring WiFi Configuration Profiles

In this section, you will enter the Homebrew Launcher so that you can restore the Wi-Fi connection slots that were overwritten in Section III.

1. 啟動『下載通信 (Download Play)』程式
1. 等到你看到兩個按鍵
  + Do not press either of the buttons
1. 同時按下『L』+『下』+『Select』鍵以啟動 Rosalina 選單

1. 選擇『Switch the hb. title to the current app.』
1. 按『B』繼續
1. 按『B』回到 Rosalina 主選單
1. 按『B』退出 Rosalina 選單
1. 按『Home』鍵，並關閉『下載通信 (Download Play)』程式
1. Relaunch the Download Play application
1. 您的主機應該就會啟動 Homebrew Launcher 了
