<summary><em>Technical Details (optional)</em></summary>

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

As we already have Homebrew access, we can use slotTool to do this.

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 [here](https://github.com/zoogie/unSAFE_MODE/) for information about the unSAFE_MODE exploit.

#### 第一節 — 準備工作

In this section, you will use Homebrew Launcher to launch slotTool, which will overwrite your Wi-Fi slots with hacked data. Then, you will copy the files needed to trigger the unSAFE_MODE exploit onto your device's SD card. Your Wi-Fi connection settings will be temporarily overwritten while the exploit is active.

1. 啟動您的主機
1. Open the Homebrew Launcher through your method of choice (likely the Internet Browser)
1. Launch slotTool from the list of homebrew
  + If you get stuck on a red screen, forcefully power off the console by holding the power button for fifteen seconds, then retry this section
1. Select the "INSTALL exploit to wifi slots 1,2,3 & shutdown" option
  + You will see some on-screen text and then your system will shut down
1. Remove your SD card from your console and connect it to your computer
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` to the root of your SD card
1. Put your SD card back into your console
