Technical Details (optional)

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

We can do this using an existing exploit, BannerBomb3.

To accomplish this, we use your system's encryption key (movable.sed) to build a DSiWare backup that 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 BannerBomb3 and unSAFE_MODE exploits: BannerBomb3, unSAFE_MODE.

{: .notice--info} ### Compatibility Notes 这些操作可在美、欧、日、韩版的主机上工作,你可通过系统版本号末尾的 U,E,J,K 字符来区分主机版本。 If your (Right/Left Shoulder), (D-Pad Up), or (A) buttons do not work, you will need to follow [an alternate branch of Seedminer](installing-boot9strap-(fredtool)). 如需帮助,请加入 [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) 并使用英文求助。(请注意,如果你身处中国大陆,访问 Discord 可能需要科学上网),你也可以到译者的 [QQ 群](https://stray-soul.site/index.php/qqgroup)寻求帮助,群号为 942052497。 {: .notice--warning} ### 你需要准备点啥? * 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 [boot9strap](https://github.com/SciresM/boot9strap/releases/download/1.4/boot9strap-1.4.zip)(直链) * 最新版本的 [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest)(下载 Luma3DS `.zip` 文件) * [usm.bin](https://github.com/zoogie/unSAFE_MODE/releases/download/v1.3/usm.bin) (direct download) #### 第一步 – 准备工作 In this section, you will copy the files needed to trigger the unSAFE_MODE exploit onto your device's SD card. 1. Your SD card should be inserted in your computer 1. Copy `usm.bin` to the root of your SD card 1. 解压 Luma3DS `.zip` 里的 `boot.firm` 和 `boot.3dsx` 到你 SD 卡的根目录 + 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. 在 SD 卡根目录创建一个名为 `boot9strap` 的文件夹 1. 从boot9strap `.zip` 文件中复制 `boot9strap.firm` 和 `boot9strap.firm.sha` 到你SD卡的 `/boot9strap/` 文件夹中 1. 从 SafeB9SInstaller `.zip` 压缩包中复制 `SafeB9SInstaller.bin` 到 SD 卡根目录下 ![]({{ "/images/screenshots/usm/usm-root-layout.png" | absolute_url }}) {: .notice--info} ![]({{ "/images/screenshots/boot9strap-folder.png" | absolute_url }}) {: .notice--info} #### 第二步 – BannerBomb3 In this section, you will trigger the BannerBomb3 exploit using the DSiWare Management menu, 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. 将SD卡重新插入你的主机 1. 启动你的主机 1. 启动你主机上的 “系统设置(System settings)” 1. Navigate to `Data Management` -> `DSiWare`-> `SD Card` ([image](/images/screenshots/bb3/dsiware-management.png)) + Your device should show the BB3 multihax menu + If this step causes your device to crash, [follow this troubleshooting guide](troubleshooting#dsiware-management-menu-crashes-without-showing-bb3-multihax-menu) 1. Use the D-Pad to navigate and press the (A) button to select "Install unSAFE_MODE" + 主机将会自动关机 #### 第三步 – 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. 将你的主机置于关机状态,按住 L + R + ↑ + A 四个按键,然后按下电源键 + Keep holding the buttons until the device boots into Safe Mode (a "system update" menu) + 如果你试了很多次依然无法进入安全模式,则也许这四个按键中有一个按错了,或是坏掉了。 If this is the case, you will need to follow [an alternate branch of BannerBomb3](installing-boot9strap-(fredtool)). 如需帮助,请加入 [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) 并使用英文求助。(请注意,如果你身处中国大陆,访问 Discord 可能需要科学上网),你也可以到译者的 [QQ 群](https://stray-soul.site/index.php/qqgroup)寻求帮助,群号为 942052497。 1. 点击 “OK” 来允许更新 + 这个步骤实际上不存在更新。 这只是触发漏洞的一部分 1. 点击 “I accept(我同意/同意する)” 1. 更新最终将失败,然后报出 `003-1099` 的错误。 这是剧本中的一部分 1. 当系统问你“你想要配置互联网设置吗?(Would you like to configure Internet settings?)”时,点击 “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. 如果漏洞执行成功,你的主机将会进入到 SafeB9SInstaller + If your device instead shows a red screen, you are missing `usm.bin` from the root of your SD card #### 第四步 – 安装 boot9strap In this section, you will install custom firmware onto your device. 1. 出现提示时,按照上屏的提示输入按键组合来安装 boot9strap + 如果上屏白屏,则请强制关机然后重做第三步 1. 安装完成后,按下 “A” 键重启主机 1. 你的主机将会在重启后进入至 Luma3DS 配置菜单中 + 如果你的主机在你尝试开机后自动关机了,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 1. 按下 “Start” 键保存设置并重启 这时,你的主机默认将会自动启动 Luma3DS。 + Luma3DS 不会给正常的主菜单增添任何看上去十分特别的东西。 如果你的主机现在已经启动到主菜单了,说明自制固件已经在运行了。 + 在下一页中,我们将会教你安装一些有用的自制程序来完成安装步骤。 #### 第五步 – 还原 WiFi 配置文件 In this section, you will trigger the BannerBomb3 exploit a second time so that you can restore the Wi-Fi connection slots that were overwritten in Section II. 1. 启动你主机上的 “系统设置(System settings)” 1. Navigate to `Data Management` -> `DSiWare`-> `SD Card` ([image](/images/screenshots/bb3/dsiware-management.png)) 1. Use the D-Pad to navigate and press the (A) button to select "Uninstall unSAFE_MODE" + 主机将会自动重启 1. 将主机关机 1. 将你的 SD 卡插入到电脑 1. 打开内存卡的 `Nintendo 3DS` -> `` -> `` -> `Nintendo DSiWare` 文件夹 1. Delete `F00D43D5.bin` from your Nintendo DSiWare folder and from your computer. 此文件之后不再需要使用 ___ ### 继续至[完成安装](finalizing-setup) {: .notice--primary}
