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.

Qué necesitas

  • Tu archivo movable.sed proveniente de haber completado Seedminer
  • The latest release of Frogminer_save (Frogminer_save.zip)
  • The latest release of b9sTool (boot.nds)
  • The latest release of Luma3DS (the Luma3DS .zip file)

Sección I - Verificación de CFW

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. Apaga tu consola
  2. Mantén pulsado el botón (Select)
  3. Enciende la consola mientras mantienes presionado (Select)
  4. If the check was successful, you will boot to the HOME Menu and you may proceed with this guide
  5. Apaga tu consola

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 to upgrade your existing CFW.

Sección 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. Reinserta tu tarjeta SD en tu consola
  2. Enciende tu consola
  3. Entra a Configuración de la consola
  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. Apaga tu consola

Section V - Flipnote Exploit

If you would prefer a visual guide to this section, one is available here.

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. Complete the initial setup process for the launched game until you reach the main menu
    • Select the left option whenever prompted during the setup process
  2. Using the touch-screen, select the large left box, then select the box with an SD card icon
  3. Once the menu loads, select the face icon, then the bottom right icon to continue
  4. Press (X) or (UP) on the D-Pad depending on which is shown on the top screen
  5. Select the second button along the top with a film-reel icon
  6. Scroll right until reel “3/3” is selected
  7. Tap the third box with the letter “A” in it
  8. Scroll left until reel “1/3” is selected
  9. Tap the fourth box with the letter “A” in it
  10. If the exploit was successful, your device will have loaded b9sTool
  11. Using the D-Pad, move to “Install boot9strap”
    • If you miss this step, the system will exit to HOME Menu instead of installing boot9strap and you will need to open Nintendo DS Connections and start over from the beginning of this section
  12. Press (A), then press START and SELECT at the same time to begin the process
  13. Once completed and the bottom screen says “done.”, exit b9sTool, then power off your device
    • You may have to force power off by holding the power button
    • 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, power off your device and continue to the next section

Section VI - Luma3DS Configuration

  1. Press and hold (Select), and while holding (Select), power on your device. This will launch Luma3DS configuration
  2. Your device should have booted into the Luma3DS configuration menu
    • 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, leave these options on the default settings (do not check or uncheck anything)
    • 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
  3. Presiona (Start) para guardar y reiniciar

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.
