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

为了做到这一点，我们将用一台已安装了自制固件的 3DS 安装一个插件，然后利用马里奥赛车 7 这个游戏中的下载通信功能进行一些操作。

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/).

### 兼容性注意

如果你想通过此方法安装自制固件，则你需要：

- 一台已安装自制固件的 3DS （**源 3DS**），它与你要破解的主机（**目标 3DS**）系统为同一区域
    + 必须是美版、日版或欧版机
    - The source 3DS can be [region changed](region-changing) to match the target 3DS if necessary
-  一份与两台主机同区的马里奥赛车 7 实体版或数字版
- An SD card for both consoles

### 你需要准备点啥？

* 最新版本的 [kartdlphax](https://github.com/PabloMK7/kartdlphax/releases/latest)（下载 `plugin.3gx`）
* 最新版本的 [SafeB9SInstaller](https://github.com/d0k3/SafeB9SInstaller/releases/download/v0.0.7/SafeB9SInstaller-20170605-122940.zip)（直链）
* 最新版本的 [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest)（下载 Luma3DS `.zip` 文件）
* The latest release of [unSAFE_MODE](https://github.com/zoogie/unSAFE_MODE/releases/latest) (the RELEASE `.zip` file)

#### Section I - Hardware Button Check (target 3DS)

#### Section II - Prep Work (source 3DS)

为了向目标 3DS 传输带有漏洞的数据，你将需要按照以下内容配置源 3DS（已安装了自制固件的 3DS）。

1. 在你的电脑中插入你的**源 3DS** 的 SD 卡
1. Copy `boot.firm` from the Luma3DS `.zip` to the root of the **source 3DS**'s SD card, replacing any existing file
    + 根目录指的是你点进 SD 卡看到的目录，你可以在这个目录下看到 Nintendo 3DS 文件夹，但请不要点进去
1. 复制 kartdlphax 的 `plugin.3gx` 到**源3DS** 的 SD 卡上对应你所拥有的马里奥赛车 7 区域版本的文件夹：
    - 美版： `luma/plugins/0004000000030800`
    - 欧版： `luma/plugins/0004000000030700`
    - 日版： `luma/plugins/0004000000030600`
    如果 `plugins` 和 `00040000...` 文件夹不存在，请先创建它们
1. 弹出 SD 卡并将其插回**源 3DS**

#### Section III - Prep Work (target 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. 在你的电脑中插入你的**目标 3DS** 的 SD 卡
1. Copy `boot.firm` and `boot.3dsx` from the Luma3DS `.zip` to the root of the **target 3DS's** SD card
1. 在 SD 卡根目录创建一个名为 `boot9strap` 的文件夹
1. Copy `boot9strap.firm` and `boot9strap.firm.sha` from the RELEASE `.zip` to the `/boot9strap/` folder on your SD card
1. 从 SafeB9SInstaller `.zip` 压缩包中复制 `SafeB9SInstaller.bin` 到 SD 卡根目录下
1. Copy `usm.bin` from the RELEASE `.zip` to the root of your SD card
1. Create a folder called `3ds` on the root of your SD card
1. Copy `slotTool.3dsx` from the `slotTool` folder inside the RELEASE `.zip` to the `/3ds/` folder on your SD card
1. 取下 SD 卡并将其插回**目标 3DS**

#### Section IV - 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. 启动 **源 3DS **
    - 若主机提示设置 Luma3DS，则你可以直接按下 START 键来保存配置
1. 进入主菜单后，同时按下 “L” + “↓” + “Select” 键调出 Rosalina 菜单
1. 选择 “Enable plugin loader”
1. 按 “B” 键退出 Rosalina 菜单
1. 启动马里奥赛车 7
    - 请确保你已经打开了无线连接
1. 选择 `本地多人游戏（Local Multiplayer）` 一个菜单应该会弹出来
    - If the screen freezes, hold the power button for fifteen seconds to force power off your console, then try again
    - 如果你先前已经启动过了 kartdlphax，则最后选定的设置将会被加载。 如果一切正确，请选中 `Use settings` 然后跳过接下来的 3 个小步骤。 如果不对，请选择 `Change settings` 然后继续操作。
1. Select your **target 3DS** console type (Old 3DS family or New 3DS family)
1. Select the following exploit type depending on your system version:
    - 11.16.0: select `xPloitInjector (11.16)`
    - 11.17.0: select `xPloitInjector (11.17)`
1. 确认菜单将会显示。 如果上屏显示的设置一切正确，请选中 `Use settings`
    - 如果不正确，请选择 `Change settings` 然后进行相应的修改
1. 选择 `Create Group`
    - 如果你用的是游戏卡带，且源 3DS 此时卡住了，那么请尝试 [将卡带中的游戏安装到系统中](dumping-titles-and-game-cartridges#installing-a-game-cartridge-directly-to-the-system)
1. 启动**目标 3DS **
    - 请确保你已经打开了无线连接
1. 在**目标 3DS**上，打开下载通信（Download Play）应用 (![]({{ "/images/download-play-icon.png" | absolute_url }}){: height="24px" width="24px"})，然后选择 “Nintendo 3DS”
1. 加入由**源 3DS** 创建的群组
1. 待**源 3DS** 检测到**目标 3DS** 后，点击“开始”
1. 多人游戏加载完成后，依次点击 `大奖赛` -> `50cc` ->（任何角色）-> `蘑菇杯` -> `OK`
1. 稍等一会儿（百分比应该会显示在**源 3DS** 上）
1. 如果漏洞执行成功，**目标 3DS** 将会启动 3DS ROP xPloit Injector
    - 如果漏洞没有成功触发，则请将**源 3DS** 和 **目标 3DS** 一起关机，然后从 `第三步 — kartdlphax` 重新开始
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 V - unSAFE_MODE

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

1. With your console still powered off, hold the following buttons: (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A), and while holding these buttons together, power on your console
    + Keep holding the buttons until the console boots into Safe Mode (a "system update" menu)
1. Press "OK" to accept the update
    + There is no update. This is part of the exploit
1. Press "I accept" to accept the terms and conditions
1. The update will eventually fail, with the error code `003-1099`. This is intended behaviour
1. When asked "Would you like to configure Internet settings?", select "Yes"
1. On the following menu, navigate to `Connection 1` -> `Change Settings` -> `Next Page (right arrow)` -> `Proxy Settings` -> `Detailed Setup` ([image](/images/screenshots/usm/safemode_highlighted.png))
1. If the exploit was successful, your console will have booted into SafeB9SInstaller
    + If your console instead freezes on a white screen, hold the POWER button until it turns off, then retry this section
    + If your console instead freezes on a red screen, you are missing `usm.bin` from the root of your SD card
    + If you get a different error, [follow this troubleshooting guide](troubleshooting#installing-boot9strap-usm)

{% include_relative include/launch-hbl-dlp.txt %}
1. Launch slotTool from the list of homebrew
1. Select "RESTORE original wifi slots 1,2,3"
1. Your console will then reboot
