<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.

### 必要なもの

* 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 [unSAFE_MODE](https://github.com/zoogie/unSAFE_MODE/releases/download/v1.3/RELEASE_v1.3.zip) (direct download)

#### セクション I - 準備

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

1. パソコンにSDカードを入れます
1. `boot9strap`という名前のフォルダをSDカードのルート上に作成します。
1. Copy `boot9strap.firm` and `boot9strap.firm.sha` from the RELEASE `.zip` to the `/boot9strap/` folder on your SD card
1. SDカードの直下に`3ds`フォルダがない場合、そのフォルダを作成します
    + This folder stores homebrew applications and data; it is different from the `Nintendo 3DS` folder that the console automatically generates
1. Copy the `slotTool` folder from the RELEASE `.zip` to the `/3ds/` folder on your SD card
1. Copy `usm.bin` from the RELEASE `.zip` to the root folder on your SD card
1. SafeB9SInstaller `.zip` から`SafeB9SInstaller.bin`をSDカードのルートへコピーします
1. Reinsert your SD card into your console
1. Power on your console
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
