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/).

### 相容性資訊

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.
{: .notice--warning}

### 必備項目

On the **source 3DS** (the 3DS with custom firmware):

* The latest release of [kartdlphax](https://github.com/PabloMK7/kartdlphax/releases/latest) (`plugin.3gx`)
* The latest release of [Luma3DS 3GX Loader Edition](https://github.com/Nanquitas/Luma3DS/releases/latest) (`boot.firm`)

On the **target 3DS** (the 3DS that you are trying to modify):

* The latest release of [SafeB9SInstaller](https://github.com/d0k3/SafeB9SInstaller/releases/download/v0.0.7/SafeB9SInstaller-20170605-122940.zip) (direct download)
* The latest release of [boot9strap](https://github.com/SciresM/boot9strap/releases/download/1.4/boot9strap-1.4.zip) (direct download)
* The latest release of [standard Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest) (the Luma3DS `.zip` file)
* 最新版的 [unSAFE_MODE](https://github.com/zoogie/unSAFE_MODE/releases/latest) (選擇 RELEASE `.zip` 檔案)

#### 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**.
