Installing boot9strap (Fredtool)

若需英語支援,請於 Discord 上的 Nintendo Homebrew 伺服器發問。

Technical Details (optional)

This method of using Seedminer for further exploitation uses your movable.sed file to decrypt any DSiWare title for the purposes of injecting an exploitable DSiWare title into the DS Internet Settings application.

This is a currently working implementation of the “FIRM partitions known-plaintext” exploit detailed here.


  • 您自 Seedminer 步驟中所取得的 movable.sed 檔案
  • The latest release of Frogminer_save (
  • The latest release of b9sTool (boot.nds)
  • The latest release of Luma3DS (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).

  1. 關閉您的主機
  2. 按住「Select」鍵
  3. 在開機時按住「Select」鍵
  4. 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。
  5. 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 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
  2. 啟動您的主機
  3. 於您主機上啟動系統設定 (System Settings)
  4. Navigate to Data Management -> DSiWare-> SD Card (image)
  5. Use the D-Pad to navigate and press the (A) button to select “Dump DSiWare”
    • Your device will automatically reboot
  6. 關閉您的主機

第五節 — Flipnote 漏洞


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
  2. 選擇觸控螢幕左方的『メモを見る』並選擇『SD カード』

  7. 選擇第三項含有字母『A』的選項
  8. 選擇第一個底片 (1/3)
  9. 選擇第四項含有字母『A』的選項
  10. 如果漏洞成功執行,您的主機將自動載入 b9sTool
  11. 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 6 of Section IV
  12. 按下『A』,然後同時按下 START 鍵和 SELECT 鍵
  13. 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
