<summary><em>Technical Details (optional)</em></summary>
<p>In order to exploit the SAFE_MODE firmware of our system, we need to inject an exploited WiFi profile.</p>
<p>We can do this using an existing exploit, BannerBomb3.</p>
<p>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.</p>
<p>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.</p>
<p>For a more technical explanation, see the following links for information on the BannerBomb3 and unSAFE_MODE exploits: <a href="https://github.com/zoogie/Bannerbomb3">BannerBomb3</a>, <a href="https://github.com/zoogie/unSAFE_MODE/">unSAFE_MODE</a>.</p>

### Compatibility Notes

これらのガイドは、システムバージョン末尾にある「U、E、J、K」にあるように、米国、欧州、日本、韓国の端末で機能します。

If your (Right/Left Shoulder), (D-Pad Up), or (A) buttons do not work, you will need to follow [an alternate branch of Seedminer](bannerbomb3). For assistance with this matter, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.

#### セクション I - 準備

In this section, you will copy the files needed to trigger the BannerBomb3 and unSAFE_MODE exploits onto your device's SD card.

1. 本体の電源が入っている場合、本体の電源を切ります
1. Open [unSAFE_MODE Exploit Injector](https://3ds.nhnarwhal.com/3dstools/unsafemode.php) on your computer
1. "ファイルを選択"から movable.sed ファイルをアップロードします。
1. 「Build and Download」をクリックしてください。
  + This will download an exploit DSiWare called `F00D43D5.bin` and a SAFE_MODE exploit data file called `usm.bin` inside of a zip archive (`unSAFE_MODE.zip`)
1. パソコンにSDカードを入れます
1. `boot.firm` と `boot.3dsx` をLuma3DSの `.zip` からSDカードのルートにコピーします
  + SDカードのルートとは、Nintendo 3DSのフォルダなどがある最初の項目のことであり、フォルダの中ではありません。
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. `boot9strap.firm`と`boot9strap.firm.sha`を boot9strap `.zip` ファイルから解凍し、SD カードのboot9strapフォルダにコピーします。
1. SafeB9SInstaller `.zip` から`SafeB9SInstaller.bin`をSDカードのルートへコピーします
1. Copy `usm.bin` from `unSAFE_MODE.zip` to the root of your SD card
    ![]({{ "/images/screenshots/bb3/usm-root-layout.png" | absolute_url }}){: .notice--info}
    ![]({{ "/images/screenshots/boot9strap-folder.png" | absolute_url }}){: .notice--info}
1. Navigate to `Nintendo 3DS` -> `<ID0>` -> `<ID1>` on your SD card
  + `<ID0>` is the 32-letter folder name that you copied in [Seedminer](seedminer)
  + `<ID1>` is a 32-letter folder inside of the `<ID0>`
  ![]({{ "/images/screenshots/bb3/dsiware-location-1.png" | absolute_url }}){: .notice--info}
1. Create a folder named `Nintendo DSiWare` inside of the `<ID1>`
  + If you already had the folder *and* there are any existing DSiWare backup files (`<8-character-id>.bin`) inside, copy them to your PC and remove them from your SD card
1. Copy the `F00D43D5.bin` file from `unSAFE_MODE.zip` to the `Nintendo DSiWare` folder

![]({{ "/images/screenshots/bb3/dsiware-location-2.png" | absolute_url }})

#### セクション II - 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 overwitten while the exploit is active.

1. 再度、SDカードを本体に挿入してください。
1. 本体の電源を入れます
1. 「本体設定」を開きます。
1. Navigate to `Data Management` -> `DSiWare`-> `SD Card` ([image](/images/screenshots/bb3/dsiware-management.png))
  + Your device should show the [Bannerbomb3 menu](/images/screenshots/bb3/usm-menu.png)
  + If this step causes your device to crash, [follow this troubleshooting guide](troubleshooting#dsiware-management-menu-crashes-without-showing-usm-menu)
1. Press (A) to select "Inject haxx"
  + Your device will automatically power off

#### セクション III - 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. With your device still powered off, hold the following buttons: (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A), and while holding these buttons together, power on your device
  + Keep holding the buttons until the device boots into Safe Mode (a "system update" menu)
  + If you're unable to get into Safe Mode after multiple attempts, one of your buttons may be failing or broken. If this is the case, you will need to follow [an alternate branch of Seedminer](bannerbomb3). For assistance with this matter, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.
1. 「OK」を押して更新を承認します
  + アップデートはありません。 そういう仕組みになっています
1. 「承諾」を押して利用規約に同意します
1. The update will eventually fail, with the error code `003-1099`. これもそうなるように仕込まれています
1. 「インターネット設定を設定しますか?」と聞かれたら、「はい」を選択します。
1. On the following menu, navigate to `Connection 1` -> `Change Settings` -> `Next Page (right arrow)` -> `Proxy Settings` -> `Detailed Setup` ([image](/images/screenshots/bb3/safemode_highlighted.png))
1. If the exploit was successful, your device will have booted into SafeB9SInstaller

#### Section IV - Installing boot9strap

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

1. When prompted, input the key combo given on the top screen to install boot9strap
  + If the top screen is blank, power off your device and re-do Section III
1. Once it is complete, press (A) to reboot your device
1. デバイスはLuma3DS設定メニューに再起動します
  + If your device shuts down when you try to power it on, ensure that you have copied `boot.firm` from the Luma3DS `.zip` to the root of your SD card
1. (Start) を押してセーブして再起動します

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 V - Restoring WiFi Configuration Profiles

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. 「本体設定」を開きます。
1. Navigate to `Data Management` -> `DSiWare`-> `SD Card` ([image](/images/screenshots/bb3/dsiware-management.png))
  + Your device should show the [Bannerbomb3 menu](/images/screenshots/bb3/usm-menu.png)
1. Use the D-Pad to navigate and press the (A) button to select "Restore slots"
  + Your device will automatically reboot
1. 本体の電源を切ります。
1. パソコンにSDカードを入れます
1. SDカードの`Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `Nintendo DSiWare`へ移動します
1. Delete `F00D43D5.bin` from your Nintendo DSiWare folder and from your computer. このファイルはもう必要ありません。
