技术细节（选看）

In order to install custom firmware on our console, we need to get Homebrew Launcher access.

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 menuhax67, which will allow us to get Homebrew Launcher access.

Once we have Homebrew Launcher access, we can run nimdsphax to install boot9strap.

See here for information about kartdlphax, here for information about menuhax67, and here for information about nimdsphax.

兼容性注意

如果你想通过此方法安装自制固件，则你需要：

  • 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
    • The source 3DS can be region changed to match the target 3DS if necessary
  • A physical or digital copy of Mario Kart 7 that is the same region as both consoles
  • An SD card for both consoles

你需要准备点啥？

Section I - 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
  2. 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
  3. 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：
    • USA: luma/plugins/0004000000030800
    • EUR: luma/plugins/0004000000030700
    • JPN: luma/plugins/0004000000030600
    • Create the plugins and 00040000... folders if they do not already exist
  4. 弹出 SD 卡并将其插回源 3DS

Section II - Prep Work (target 3DS)

In this section, you will set up the files that the target 3DS will need to install custom firmware.

  1. 在你的电脑中插入你的目标 3DS 的 SD 卡
  2. Copy boot.firm and boot.3dsx from the Luma3DS .zip to the root of the target 3DS’s SD card
  3. 在 SD 卡根目录创建一个名为 boot9strap 的文件夹
  4. 从boot9strap .zip 文件中复制 boot9strap.firm 和 boot9strap.firm.sha 到你SD卡的 /boot9strap/ 文件夹中
  5. 从 SafeB9SInstaller .zip 压缩包中复制 SafeB9SInstaller.bin 到 SD 卡根目录下
  6. 检查 SD 卡的根目录是否存在一个名为 3ds 的文件夹，如果没有则手动新建一个
    • This folder stores homebrew applications and data; it is different from the Nintendo 3DS folder that the console automatically generates
  7. Copy the nimdsphax folder from the nimdsphax .zip to the /3ds/ folder on your SD card
  8. Copy menuhax67_installer.3dsx from the menuhax .zip to the /3ds/ folder on your SD card
  9. Copy Launcher.dat from the folder for your model and region inside the menuhax .zip to the root of your SD card
  10. 取下 SD 卡并将其插回目标 3DS

Section III - 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 install menuhax67, a Homebrew Launcher entrypoint. Your HOME Menu settings will be temporarily inaccessible on the target 3DS while this exploit is active.

  1. 启动 **源 3DS **
    • If you are prompted to set up Luma3DS, just press START to save the configuration
  2. 进入主菜单后，同时按下 “L” + “↓” + “Select” 键调出 Rosalina 菜单
  3. 选择 “Enable plugin loader”
  4. 按 “B” 键退出 Rosalina 菜单
  5. 启动马里奥赛车 7
    • Ensure that wireless connectivity is enabled
  6. 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
    • If you have launched kartdlphax previously, the last selected settings will be loaded. 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。
  7. Select your target 3DS console type (Old 3DS family or New 3DS family)
  8. Select the following exploit type depending on your system version:
    • 11.16.0: select xPloitInjector (11.16)
    • 11.17.0: select xPloitInjector (11.17)
  9. 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
    • If the settings are not correct, press Change settings and modify them accordingly
  10. 选择 Create Group
  11. 启动**目标 3DS **
    • Ensure that wireless connectivity is enabled
  12. 在目标 3DS上，打开下载通信（Download Play）应用 ()，然后选择 “Nintendo 3DS”
  13. 加入由源 3DS 创建的群组
  14. 待源 3DS 检测到目标 3DS 后，点击“开始”
  15. 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
  16. 稍等一会儿（百分比应该会显示在源 3DS 上）
  17. 如果漏洞执行成功，目标 3DS 将会启动 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

Section IV - Installing menuhax67

  1. Press (Y) + (D-Pad Down) to install menuhax67
    • The console will automatically power off
  2. Power on your console
  3. Tap on the small HOME Menu settings icon in the top left of the bottom screen ()
    • If the console freezes for a while and then crashes, make sure you have Launcher.dat on the root of your SD card
  4. If the exploit was successful, your console will have booted into the Homebrew Launcher
  5. Launch nimdsphax from the list of homebrew
  6. 如果一切成功的话，你将自动进入 SafeB9SInstaller
    • If your console freezes on a red screen, hold the POWER button until it turns off, then try running menuhax again by powering on your console and tapping on the HOME Menu settings icon

第五步 – 安装 boot9strap

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

  1. When prompted, input the key combo given on the top screen to install boot9strap
  2. Once it is complete, press (A) to reboot your console
  3. 你的主机应该会在开机后进入 Luma3DS 配置菜单
    • Luma3DS 配置菜单用于设置 Luma3DS 自制固件的可选功能 其中有许多功能可用于个性化或调试
    • 对于本手册的目的而言，请不要修改默认设置（不要选中或者取消选中任何东西）
    • 如果你的主机在你尝试开机后直接自动关机了，请确认你已经从 Luma3DS .zip 中复制了 boot.firm 文件到你的 SD 卡根目录中
  4. 按下 “Start” 键保存设置并重启

At this point, your console will boot to Luma3DS by default.

  • Luma3DS does not look any different from the normal HOME Menu. If your console has booted into the HOME Menu, it is running custom firmware.
  • On the next page, you will install useful homebrew applications to complete your setup.

Section VI - Removing menuhax67

In this section, you will use the Homebrew Launcher to remove menuhax67, which will let you access the HOME Menu Settings option normally.
