Technical Details (optional)

In order to exploit the SAFE_MODE firmware of our system, we need to inject an exploited WiFi profile.

We can do this using an existing exploit, BannerBomb3.

To accomplish this, we use your system’s encryption key (movable.sed) to build a DSiWare backup that exploits the system in order to inject the exploited WiFi profile into your connections list.

Once the WiFi profile has been injected, we will use SAFE_MODE, which is a recovery feature present on all 3DS consoles, to activate the exploited WiFi profile.

For a more technical explanation, see the following links for information on the BannerBomb3 and unSAFE_MODE exploits: BannerBomb3, unSAFE_MODE.

Compatibility Notes

Ces instructions fonctionnent dans les régions USA, Europe, Japon et Corée indiquées par les lettres U, E, J ou K après le numéro de version de la console.

If your (Right/Left Shoulder), (D-Pad Up), or (A) buttons do not work, you will need to follow an alternate branch of Seedminer. For assistance with this matter, join Nintendo Homebrew on Discord and ask, in English, for help.

Ce dont vous avez besoin

Section I - Préparatifs

In this section, you will copy the files needed to trigger the unSAFE_MODE exploit onto your device’s SD card.

  1. Your SD card should be inserted in your computer
  2. Copy usm.bin to the root of your SD card
  3. Copiez boot.firm et boot.3dsx depuis Luma3DS .zipvers la racine de votre carte SD
    • La racine de la carte SD représente le répertoire initial de la carte SD où vous pouvez voir le dossier Nintendo 3DS, mais ce n’est pas à l’intérieur de ce dernier
  4. Créez un dossier à la racine de votre carte SD nommé boot9strap
  5. Copiez boot9strap.firm et boot9strap.firm.sha depuis le fichier “.zip” de boot9strap vers le dossier /boot9strap/ sur votre carte SD
  6. Copiez SafeB9SInstaller.bin depuis le fichier .zip de SafeB9SInstaller à la racine de votre carte SD

Section II - BannerBomb3

In this section, you will trigger the BannerBomb3 exploit using the DSiWare Management menu, which can be used to overwrite your Wi-Fi slots with hacked data. Your Wi-Fi connection settings will be temporarily overwritten while the exploit is active.

  1. Réinsérez votre carte SD dans votre 3DS
  2. Allumez votre console
  3. Lancez les Paramètres de la console
  4. Navigate to Data Management -> DSiWare-> SD Card (image)
    • Your device should show the BB3 multihax menu
    • If this step causes your device to crash, follow this troubleshooting guide
    • If the BB3 multihax menu says “cfw installed already”, you already have custom firmware and should continue from here
  5. Use the D-Pad to navigate and press the (A) button to select “Install unSAFE_MODE”
    • Votre console s’éteindra automatiquement

Section III - unSAFE_MODE

In this section, you will enter Safe Mode (a feature available on all 3DS family devices) and navigate to a menu where unSAFE_MODE will be triggered, which will launch you into the boot9strap (custom firmware) installer.

  1. With your device still powered off, hold the following buttons: (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A), and while holding these buttons together, power on your device
    • Keep holding the buttons until the device boots into Safe Mode (a “system update” menu)
    • If you’re unable to get into Safe Mode after multiple attempts, one of your buttons may be failing or broken. If this is the case, you will need to follow an alternate branch of BannerBomb3. For assistance with this matter, join Nintendo Homebrew on Discord and ask, in English, for help.
  2. Appuyez sur “OK” pour accepter la mise à jour
    • Aucune mise à jour nécessaire. Ceci fait partie de l’exploit
  3. Appuyez sur « J’accepte » pour accepter les termes et conditions
  4. The update will eventually fail, with the error code 003-1099. Ne vous inquiétez pas, c’est normal
  5. Lorsque votre console vous demande “Paramétrer la connexion Internet de la console ?”, sélectionnez “Paramétrer”
  6. On the following menu, navigate to Connection 1 -> Change Settings -> Next Page (right arrow) -> Proxy Settings -> Detailed Setup (image)
  7. Si l’exploit a réussi, votre console devrait avoir démarré sur SafeB9SInstaller
    • If your device instead shows a red screen, you are missing usm.bin from the root of your SD card

Section IV - Installing boot9strap

In this section, you will install custom firmware onto your device.

  1. Lorsque vous y êtes invité, entrez la combinaison de touches indiquée sur l’écran supérieur pour installer boot9strap
    • If the top screen is blank, power off your device and re-do Section III
  2. Once it is complete, press (A) to reboot your device
  3. Votre console va redémarrer dans la configuration de Luma3DS
    • 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, these settings will be left on default settings
    • 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
  4. Appuyez sur (Start) pour enregistrer les modifications et redémarrer

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 V - Restoring WiFi Configuration Profiles

In this section, you will trigger the BannerBomb3 exploit a second time so that you can restore the Wi-Fi connection slots that were overwritten in Section II.

  1. Lancez les Paramètres de la console
  2. Navigate to Data Management -> DSiWare-> SD Card (image)
  3. Use the D-Pad to navigate and press the (A) button to select “Uninstall unSAFE_MODE”
    • Your device will automatically reboot
  4. Éteignez votre 3DS
  5. Insérez votre carte SD dans votre ordinateur
  6. Naviguez vers Nintendo 3DS -> <ID0> -> <ID1> -> Nintendo DSiWare sur votre carte SD
  7. Delete F00D43D5.bin from your Nintendo DSiWare folder and from your computer. Ce fichier ne sera plus nécessaire
