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

### 必備項目

* 您自 [Seedminer](seedminer) 步驟中所取得的 `movable.sed` 檔案
* 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)

#### 第一節 — 檢查自製韌體

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. 關閉您的主機
1. 按住「Select」鍵
1. 在開機時按住「Select」鍵
1. 如果您能正常開機至 HOME 主選單的話，則代表檢查通過，您能放心地繼續遵循以下步驟。
1. 關閉您的主機

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! 前往至 [檢查是否已安裝自製韌體](checking-for-cfw) 以更新您現有的自製韌體。

#### 第二節 — 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. 將 SD 卡插回主機中
1. 啟動您的主機
1. 於您主機上啟動系統設定 (System Settings)
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#dsiware-management-menu-crashes-without-showing-bb3-multihax-menu)
1. Use the D-Pad to navigate and press the (A) button to select "Dump DSiWare"
  + Your device will automatically reboot
1. 關閉您的主機
  
#### 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. 將 SD 卡插入至電腦中
1. 在電腦上開啟 [DSIHaxInjector_new](https://jenkins.nelthorya.net/job/DSIHaxInjector_new/build?delay=0sec)

  + `<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. 解壓 Luma3DS `.zip` 內的 `boot.firm` 及 `boot.3dsx` 到 SD 卡的根目錄底下
  + 「SD 卡的根目錄」指的是你的 SD 卡含有 Nintendo 3DS 資料夾的目錄，而非該資料夾內部
1. 將 `boot.nds` (B9STool) 複製到 SD 卡根目錄中
1. 解壓 Frogminer_save `.zip` 中的 `private` 資料夾到 SD 卡的根目錄底下
1. 將 SD 卡插回主機中
1. 啟動您的主機

    ![]({{ "/images/screenshots/fredtool/fredtool-root-layout.png" | absolute_url }})

#### 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. 於您主機上啟動系統設定 (System Settings)
1. Navigate to `Data Management` -> `DSiWare`-> `SD Card` ([image](/images/screenshots/bb3/dsiware-management.png))
1. Select the "Haxxxxxxxxx!" title
1. 選擇『複製 (Copy)』並選擇『OK』
1. 回到系統設定主選單
1. Navigate to `Internet Settings` -> `Nintendo DS Connections`, then select "OK" ([image](/images/screenshots/fredtool/dsconnection.png))
1. 如果漏洞成功執行，您的主機將自動啟動『うごくメモ帳 (Flipnote Studio)』

##### 第五節 — Flipnote 漏洞

如果您需要圖片幫助請見[此](https://zoogie.github.io/web/flipnote_directions/)。
{: .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. 完成遊戲的初始設定直到出現遊戲主選單為止
  + 在設定過程中出現提示時，選擇左方的『いらない』選項
1. 選擇觸控螢幕左方的『メモを見る』並選擇『SD カード』
1. 在載入選單後，請選擇螢幕上的臉型圖示並選擇右下角的按鈕以繼續
1. 依上方螢幕所顯示的選項，透過「X」或「上」按鈕進行選擇
1. 選擇觸控螢幕上方的底片按鈕
1. 選擇最後一個底片 (3/3)
1. 選擇第三項含有字母『A』的選項
1. 選擇第一個底片 (1/3)
1. 選擇第四項含有字母『A』的選項
1. 如果漏洞成功執行，您的主機將自動載入 b9sTool
1. 使用方向鍵移動至『Install boot9starp』
  + 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 IV
1. 按下『A』，然後同時按下 START 鍵和 SELECT 鍵
1. 一旦下方螢幕提示『done.』，那麼就已經完成了，退出 b9stool 並關閉主機
  + 您可能得按住電源紐強制關機
  + 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. 關閉您的主機
1. 將 SD 卡插入至電腦中
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 不會特別在 HOME 主選單中新增任何特別的東西。 如果你的主機已經啟動到了 HOME 主選單，這代表自製韌體已經在運行了。
  + 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. 於您的 SD 卡中，移動至 `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `Nintendo DSiWare`
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. 將 SD 卡插回主機中
1. 啟動您的主機
1. 於您主機上啟動系統設定 (System Settings)
1. Navigate to `Data Management` -> `DSiWare`-> `SD Card` ([image](/images/screenshots/bb3/dsiware-management.png))
1. Select the "Nintendo DSi™" title
1. 選擇『複製 (Copy)』並選擇『OK』
