Technical Details (optional)

For technical details on the exploits that you will be using on this page, see “DSiWare_Exports CTCert verification” and “FIRM partitions known-plaintext” here.

To use the magnet link for frogcert.bin on this page, you will need a torrent client like qBittorrent or Deluge.
If you are unable to install one, follow Bannerbomb3 instead.

Wat je nodig hebt

  • Your movable.sed file from completing Seedminer or nimhax on the root of your SD card
  • frogcert.bin (magnet link)
  • The latest release of Frogtool
  • The latest release of b9sTool

Deel I - CFW Controle

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. Schakel je 3DS uit
  2. Houd de (Select) knop ingedrukt
  3. Zet je 3DS aan terwijl je de (Select) knop ingedrukt houdt
  4. If the check was successful, you will boot to the HOME Menu and you may proceed with this guide
  5. Schakel je 3DS uit

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.

Deel II - Voorbereiding

  1. Schakel je 3DS uit
  2. Plaats je SD kaart in je computer
  3. Kopieer boot.firm en boot.3dsx van de Luma3DS .zip naar de hoofdmap van je SD-kaart
  4. Copy boot.nds (b9sTool) from the b9sTool release .zip to the root of your SD card
  5. Copy Frogtool.3dsx to the /3ds/ folder on your SD card
  6. Copy frogcert.bin to the root of your SD card
  7. Stop je SD kaart terug in je 3DS
  8. Zet je 3DS aan

Section III - Patching DS Download Play

  2. Launch Frogtool from the list of homebrew
  3. Select the “INJECT patched DS Download Play” option
  4. Frogtool will automatically run and inject the JPN version of Flipnote Studio into your DS Download Play
  5. Once this operation has finished, read the screens and check if the process was successful
  6. Tap the touch screen, then select “BOOT patched DS Download Play”
  7. Als de exploit successful was, zal jouw 3DS de JPN versie van Flipnote Studio hebben opgestart
    • If you get stuck on a black screen, follow this page, then try again

Section IV - 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 b9sTool, 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
    • If you encounter an issue while doing this section, check this troubleshooting guide for your issue
  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. 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
  2. Druk op (Start) om op te slaan en opnieuw op te starten

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.
