Technische 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.

Kompatibilitätshinweise

Diese Anleitung funktioniert mit den folgenden Konsolenregionen: USA, Europa, Japan und Korea. Diese werden mit den Buchstaben U, E, J oder K nach der Systemversion angezeigt.

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.

Was du brauchst

  • Die neueste Version vom SafeB9SInstaller (Direkter Download)
  • Die neueste Version von boot9strap (Direkter Download)
  • Die neueste Version von Luma3DS (die Luma3DS .zip Datei)
  • usm.bin (direct download)

Abschnitt I - Vorbereitungen

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. Copy boot.firm and boot.3dsx from the Luma3DS .zip to the root of your SD card
    • The root of the SD card refers to the initial directory on your SD card where you can see the Nintendo 3DS folder, but are not inside of it
  4. Erstelle einen Ordner namens boot9strap im Stammverzeichnis deiner SD-Karte
  5. Kopiere boot9strap.firm und boot9strap.firm.sha aus der boot9strap .zip in den /boot9strap/-Ordner auf deiner SD-Karte
  6. Copy SafeB9SInstaller.bin from the SafeB9SInstaller .zip to the root of your SD card

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. Stecke deine SD-Karte nun wieder in deinen 3DS
  2. Schalte deine Konsole an
  3. Launch System Settings on your device
  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”
    • Your device will automatically power off

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. Press “OK” to accept the update
    • There is no update. This is part of the exploit
  3. Press “I accept” to accept the terms and conditions
  4. The update will eventually fail, with the error code 003-1099. This is intended behaviour
  5. When asked “Would you like to configure Internet settings?”, select “Yes”
  6. On the following menu, navigate to Connection 1 -> Change Settings -> Next Page (right arrow) -> Proxy Settings -> Detailed Setup (image)
  7. If the exploit was successful, your device will have booted into 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. When prompted, input the key combo given on the top screen to install boot9strap
    • If the top screen is blank, power off your device and re-do Section III
  2. Sobald dies abgeschlossen ist, drücke (A) um das Gerät neuzustarten
  3. Dein Gerät sollte neu starten und die Luma3DS Konfiguration anzeigen
    • 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. Drücke (Start) zum Speichern und neustarten

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. Launch System Settings on your device
  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. Schalte deinen 3DS aus
  5. Stecke deine SD-Karte in deinen Computer
  6. Navigiere zu Nintendo 3DS -> <ID0> -> <ID1> -> Nintendo DSiWare auf deiner SD-Karte
  7. Delete F00D43D5.bin from your Nintendo DSiWare folder and from your computer. This file will not be needed anymore
