Technical Details (optional)

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

To accomplish this, we can use the Download Play functionality of the game Mario Kart 7, using a 3DS with custom firmware already installed along with a custom game plugin.

This custom plugin will send a hacked payload to an unhacked console, which then 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 kartdlphax and unSAFE_MODE exploits: kartdlphax, unSAFE_MODE.

Compatibility Notes

Om deze instructies te volgen, heb je het volgende nodig:

  • Een tweede 3DS met custom firmware (de bron 3DS) die dezelfde regio is als de 3DS die je probeert te veranderen (de doel 3DS)
    • The consoles must be USA, JPN, or EUR region consoles
  • Een fysieke of digitale kopie van Mario Kart 7 dat dezelfde regio heeft als beide consoles
  • Een SD-kaart voor beide apparaten

Wat je nodig hebt

Op de source 3DS (de 3DS met custom firmware):

Op de target 3DS (de 3DS die je probeert te wijzigen):

Section I - Hardware Button Check (target 3DS)

  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 to a system update screen (this is Safe Mode)
  2. If you see the system update screen, press Cancel
    • Your device will power off
    • If the device boots to the HOME Menu, just power off your device

If you do not boot into Safe Mode, the system update menu after multiple attempts, you cannot follow this method. If this is the case, join Nintendo Homebrew on Discord and ask, in English, for help.

Section II - Prep Work (source 3DS)

In this section, you will set up your source 3DS (the 3DS with custom firmware) for delivery of the exploit data to the target 3DS.

  1. Plaats de SD-kaart van je bron 3DS in je computer
  2. Kopieer Luma 3GX Loader Edition’s boot.firm naar de hoofdmap van de bron 3DS’s SD-kaart, die elk bestaand bestand vervangt
    • De hoofdmap van de SD-kaart verwijst naar de bovenste map van de SD-kaart, waarin je alle mappen op de SD-kaart kunt zien, waaronder de Nintendo 3DS map, zonder je in de Nintendo 3DS map te bevinden
  3. Kopieer kartdlphax’s plugin.3gx naar de volgende map op de bron 3DS’s SD-kaart, afhankelijk van de regio van je kopie van Mario Kart 7:
    • USA: luma/plugins/0004000000030800
    • EUR: luma/plugins/0004000000030700
    • JPN: luma/plugins/0004000000030600
    • Maak de plugins en 00040000... mappen aan als ze nog niet bestaan
  4. Haal de SD-kaart uit en stop deze in de bron 3DS

Section III - Prep Work (target 3DS)

In this section, you will copy the files needed to trigger the unSAFE_MODE exploit onto your target 3DS (the 3DS that you are trying to modify)’s SD card.

  1. Plaats de SD-kaart van je doel 3DS in je computer
  2. Kopieer boot.firm en boot.3dsx van de standaard Luma3DS .zip naar de hoofdmap van je SD-kaart
  3. Maak een map genaamd boot9strap op de hoofdmap van je SD-kaart
  4. Kopieer boot9strap.firm en boot9strap.firm.sha van de boot9strap .zip naar de /boot9strap/ map op je SD-kaart
  5. Kopieer SafeB9SInstaller.bin van de SafeB9SInstaller .zip naar de hoofdmap van je SD-kaart
  6. Copy usm.bin from the unSAFE_MODE .zip to the root of your SD card
  7. Create a folder called 3ds on the root of your SD card
  8. Copy the slotTool folder from the unSAFE_MODE .zip to the 3ds folder on your SD card
  9. Haal de SD-kaart uit en stop deze in de doel 3DS

Section IV - kartdlphax

In this section, you will use Download Play to transfer the exploit data from the source 3DS to the target 3DS, 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. Zet de bron 3DS aan
    • Als je gevraagd wordt om Luma3DS in te stellen, druk gewoon op START om de configuratie op te slaan
  2. Eenmaal in het HOME Menu, druk op (Left Shoulder) + (Down D-Pad) + (Select) om het Rosalina menu te tonen
  3. Selecteer “Enable plugin loader”
  4. Druk op (B) om het Rosalina menu af te sluiten
  5. Start Mario Kart 7
    • Zorg ervoor dat draadloze verbinding is ingeschakeld
  6. Navigate to Local Multiplayer. A menu should pop up
    • If the screen freezes, hold the power button for fifteen seconds to force power off your device, then try again
    • If you have launched kartdlphax previously, the last selected settings will be loaded. If they are correct, select Use settings and skip the next 3 steps. If they are incorrect, select Change settings and proceed.
  7. Select your target 3DS device type (Old 3DS family or New 3DS family)
  8. Select the exploit type 3DS ROP xPloit Injector
  9. A confirmation menu will show up. If the settings shown on the top screen are correct, select Use settings
    • If the settings are not correct, press Change settings and modify them accordingly
  10. Select Create Group
  11. Zet de doel 3DS aan
    • Zorg ervoor dat draadloze verbinding is ingeschakeld
  12. Op de doel 3DS, open de Download Play applicatie (), selecteer dan “Nintendo 3DS”
  13. Word lid van de groep gemaakt door de bron 3DS
  14. Selecteer “Start” op de bron 3DS zodra de doel 3DS is gedetecteerd
  15. Zodra multiplayer is geladen, navigeer naar Grand Prix -> 50cc -> (any driver) -> Mushroom Cup -> OK
  16. Wacht een tijdje (een percentage moet worden weergegeven op de bron 3DS)
  17. If the exploit was successful, the target 3DS will have booted into the 3DS ROP xPloit Injector
    • If the exploit was not successful, power off the source 3DS and target 3DS and start again from the beginning of Section III - kartdlphax
  18. Press (X) to inject unSAFE_MODE
  19. If the injection was successful, the screen will turn green and the target 3DS will automatically power off
    • If the screen turns red, power off the target 3DS and start again from the beginning of Section III - kartdlphax. If this doesn’t work, ask for help at Nintendo Homebrew on Discord)

You will not need to use your source 3DS to complete any further steps on this guide. Any further steps should only be completed on the target 3DS.

Section V - 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)
  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”
