<p>This method of using Seedminer for further exploitation uses your <code>movable.sed</code> file to decrypt any DSiWare title for the purposes of injecting an exploitable DSiWare title into the DS Internet Settings application.</p>
<p>This is a currently working implementation of the "FIRM partitions known-plaintext" exploit detailed <a href="https://www.3dbrew.org/wiki/3DS_System_Flaws">here</a>.</p>

### 必要なもの

* [Seedminer](seedminer) より作成した、 `movable.sed` ファイル
* The latest release of [Frogminer_save](https://github.com/zoogie/Frogminer/releases/latest) (`Frogminer_save.zip`)
* The latest release of [b9sTool](https://github.com/zoogie/b9sTool/releases/latest) (`boot.nds`)
* The latest release of [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest) (the Luma3DS `.zip` file)

#### Section I - CFW Check

As an additional safety measure, we will perform an additional check for custom firmware. This is because using this method when custom firmware is already installed has a risk of bricking the console (rendering it unusable without recovery methods like [ntrboot](ntrboot)).

1. 本体の電源を切ります。
1. Hold the (Select) button
1. Power on your device while still holding the (Select) button
1. If the check was successful, you will boot to the HOME Menu and you may proceed with this guide
1. 本体の電源を切ります。

If you see a configuration menu or the console immediately powers off, you already have CFW, and continuing with these instructions may BRICK your device! Follow [Checking for CFW](checking-for-cfw) to upgrade your existing CFW.

#### セクション II - BannerBomb3

In this section, you will trigger the BannerBomb3 exploit using the DSiWare Management menu and copy the resulting file dump to your computer so that you can use it on the next section.

1. Use the D-Pad to navigate and press the (A) button to select "Dump DSiWare"
  + Your device will automatically power off
  
#### Section III - Prep Work

In this section, you will copy the files necessary to temporarily replace DS Connection Settings with Flipnote Studio, which is used to launch the boot9strap (custom firmware) installer.

1. パソコンにSDカードを入れます
1. Open the [DSIHaxInjector_new](https://jenkins.nelthorya.net/job/DSIHaxInjector_new/build?delay=0sec) website on your computer

  + `<ID0>` is the 32-letter folder name that you copied in [Seedminer](seedminer)
  + `<ID1>` is a 32-letter folder inside of the `<ID0>` 
1. Delete `F00D43D5.bin` from your Nintendo DSiWare folder
1. Copy the `42383841.bin`  file from the `hax` folder of the downloaded DSiWare archive (output_(name).zip) to the `Nintendo DSiWare` folder
  ![]({{ "/images/screenshots/bb3/dsiware-location-4.png" | absolute_url }}){: .notice--info} 
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. SDカードのルートに`boot.nds` (B9STool) をコピーします
1. Frogminer_save `.zip`から`private`フォルダをSDカードのルートにコピーします

#### Section IV - Overwriting DS Connection Settings

In this section, you will copy the hacked DS Connection Settings DSiWare to internal memory, which will temporarily replace it with Flipnote Studio.

1. デバイスの電源を入れます
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))
1. Select the "Haxxxxxxxxx!" title
1. 「コピー」を選択し、「OK」を選択します
1. システム設定のメインメニューに戻ります
1. Navigate to `Internet Settings` -> `Nintendo DS Connections`, then select "OK" ([image](/images/screenshots/fredtool/dsconnection.png))
1. 完了した場合、日本語のうごくメモ帳が開きます

#### Section V - Flipnote Exploit

このセクションのビジュアルガイドをご希望の場合は、 [このリンク](https://zoogie.github.io/web/flipnote_directions/) からご利用いただけます。
{: .notice--info}

In this section, you will perform a series of very specific steps within Flipnote Studio that, when performed correctly, will launch the boot9strap (custom firmware) installer.

1. メインメニューに到達するまで、うごくメモ帳の初期設定プロセスを完了します
  + セットアッププロセス中にプロンプトが表示されるたびに左のオプションを選択します
1. タッチスクリーンを使用して、大きな左のボックスを選択し、SDカードアイコンのあるボックスを選択します
1. メニューが読み込まれたら、顔アイコンを選択し、右下アイコンをクリックして続行します
1. 上部画面に表示されている(X) ボタンまたは(UP) 矢印を押します
1. フィルムリールアイコン付きの上部にある2番目のボタンを選択します
1. 「3/3」リールが選択されるまで右にスクロール
1. 「A」という文字が入った3番目のボックスをタップしてください
1. "1/3" リールが選択されるまで左にスクロール
1. 「A」の文字が入った4番目のボックスをタップしてください
1. エクスプロイトが成功した場合、お使いのデバイスは b9sTool をロードします。
1. 方向ボタンを使って「boot9strapのインストール(Install boot9strap)」に移動します
  + If you miss this step, the system will exit to HOME Menu instead of installing boot9strap and you will need to open System Settings, then start over from Step 7 of Section III
1. (A) を押し、同時にSTARTとSELECTを押してプロセスを開始します
1. 完了し、下の画面に「完了(done)」と表示されたら、b9sToolを終了し、デバイスの電源を切ってください
  + 電源ボタンを長押しして強制的に電源を切る必要があるかもしれません
  + 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
  + If you see the Luma Configuration screen, press (Start) to reboot, then continue with the guide

#### Section VI - Luma3DS Verification

Due to the nature of the exploit used, it is occasionally (but rarely) possible for boot9strap to not actually get installed. This section will therefore verify that boot9strap was successfully installed by seeing if some files that are normally automatically generated by Luma3DS were created.

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. Verify that a `luma` folder exists and that `config.ini` is inside of it
  + The existence of these folders and files confirms that Luma3DS is installed
  + If you do not see the `luma` folder or `config.ini`, [follow this troubleshooting guide](https://github.com/zoogie/b9sTool/blob/master/TROUBLESHOOTING.md)

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 VII - Restoring DS Connection Settings

In this section, you will restore DS Connection Settings to the way it was before it was temporarily replaced with Flipnote Studio in Section IV.

1. SDカードの`Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `Nintendo DSiWare`へ移動します
1. Copy the `42383841.bin`  file from the `clean` folder of the downloaded DSiWare archive (output_(name).zip) to the `Nintendo DSiWare` folder, replacing the existing one
1. 再度、SDカードを本体に挿入してください。
1. デバイスの電源を入れます
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))
1. Select the "Nintendo DSi™" title
1. 「コピー」を選択し、「OK」を選択します
