<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.

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](https://github.com/zoogie/Bannerbomb3), [unSAFE_MODE](https://github.com/zoogie/unSAFE_MODE/).

### 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](installing-boot9strap-(fredtool)). For assistance with this matter, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.

### 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 [boot9strap](https://github.com/SciresM/boot9strap/releases/download/1.4/boot9strap-1.4.zip) (direct download)
* The latest release of [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest) (the Luma3DS `.zip` file)
* [usm.bin](https://github.com/zoogie/unSAFE_MODE/releases/download/v1.3/usm.bin) (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 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. `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

#### 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 overwritten 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 BB3 multihax menu
  + If this step causes your device to crash, [follow this troubleshooting guide](troubleshooting#bannerbomb3)
  + If the BB3 multihax menu says "cfw installed already", you already have custom firmware and should continue from [here](checking-for-cfw)
1. Use the D-Pad to navigate and press the (A) button to select "Install unSAFE_MODE"
  + 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 BannerBomb3](installing-boot9strap-(fredtool)). 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/usm/safemode_highlighted.png))
1. If the exploit was successful, your device will have booted into SafeB9SInstaller
  + If your device instead shows a red screen, you are missing `usm.bin` from the root of your SD card

#### 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
  + Luma3DS configuration menu are settings for the Luma3DS custom firmware. Many of these settings may be useful for customization or debugging
  + For the purpose of this guide, these settings will be left on default settings
  + 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))
1. Use the D-Pad to navigate and press the (A) button to select "Uninstall unSAFE_MODE"
  + 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。
