Détails techniques (facultatif)

MSET9 is an exploit for the System Settings application developed by zoogie. It exploits a flaw where the ID1 (the second 32-character folder name inside of the Nintendo 3DS folder, inside of the ID0) can be any name as long as it is 32 characters. Performing a specific sequence of actions results in the console executing the instructions that are encoded into the ID1 folder name, which can be used to grant full control over the 3DS.

Notes de compatibilité

This page requires a computer running Windows, Linux, or macOS. If you have an Android phone/tablet or a Chromebook, follow Installing boot9strap (MSET9 Play Store) instead. If you do not have access to any of these devices, you will need to use an alternate exploit.

Ce dont vous avez besoin

  • The latest release of MSET9 (the Release .zip file)
  • Any 3.x version of Python installed on your computer
    • If you are on Linux or macOS, you may already have Python 3. Check by opening a Terminal window and entering python3 -V. If this returns a version number, it will work for this guide.

Instructions

On this page, you will use the MSET9 script, which is used to trigger MSET9. If you get a numbered error (e.g. Error 01) when running the script, the solution to that error can most likely be found on the troubleshooting page.

Section I - Préparatifs

In this section, you will prepare the SD card data necessary for the MSET9 exploit to trigger.

  1. Power on your console with your SD card inserted
  2. Open Mii Maker
  3. Wait for your console to reach the “Welcome to Mii Maker” screen, then exit Mii Maker
    • You may see this screen, which indicates the necessary data has been created
    • If you just reach the normal Mii Maker screen, exit Mii Maker and continue to the next step
  4. Éteignez votre console
  5. Insérez votre carte SD dans votre ordinateur

  6. Copy everything from the Release .zip to the root of your SD card, overwriting any existing files

    • Windows: Double-click mset9.bat
    • macOS: Double-click mset9.command and enter your password if prompted
    • Linux: open a Terminal window, cd to the root of your SD card, then type python3 mset9.py and press Enter

  8. Type the number corresponding to your console model and version, then press Enter
    • The window should change to this:

    • Ensure that the correct console model and version is displayed
  9. Type 1, then press Enter to ensure your console is prepared for MSET9
    • If you get an error, check the troubleshooting, then try again
    • If you get “Error 10: Database(s) malformed or missing!”, follow the instructions here, then go back to Step 7 of this section
  10. If you see the message “Everything appears to be functional!”, press Enter to close the MSET9 script
  11. Réinsérez votre carte SD dans votre console
  12. Power on your console

Section II - MSET9

In this section, you will trigger MSET9 to launch SafeB9SInstaller (the custom firmware installer).

These instructions must be followed EXACTLY, so double-check EVERYTHING you are doing to avoid errors!

  1. Hover over the System Settings icon using the D-Pad (do not select it yet)
  2. Power off, then power on your console
  3. Press (A) to launch System Settings
  4. Navigate to Data Management -> Nintendo 3DS -> Extra Data (image)
  5. Do not press any buttons or touch the screen
  6. With the console STILL ON, and without pressing any buttons or touching the screen, remove your SD card from your console
    • The menu will refresh and say that no SD card is inserted, which is expected
  7. Insérez votre carte SD dans votre ordinateur
  8. Run the MSET9 script:
    • Windows: Double-click mset9.bat
    • macOS: Double-click mset9.command and enter your password if prompted
    • Linux: open a Terminal window, cd to the root of your SD card, then type python3 mset9.py and press Enter
  9. Type the number corresponding to your console model and version, then press Enter
  10. In the MSET9 window, type 2, then press Enter to inject MSET9
    • You should see “MSET9 successfully injected!”
  11. Press Enter to close the MSET9 script
  12. Reinsert your SD card into your console without pressing any buttons or touching the screen
  13. Si l’exploit a réussit, vous devriez avoir démarré dans SafeB9SInstaller
    • If you get a red screen or the console gets stuck on a loading screen, follow the troubleshooting guide

Section III - Installation de boot9strap

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

  1. Lorsque vous y êtes invité, entrez la combinaison de touches indiquée sur l’écran supérieur pour installer boot9strap
    • Si une étape sur l’écran du bas a du texte rouge, et que vous n’êtes pas invité à entrer une combinaison de touches, suivez ce guide de dépannage
  2. Once it is complete, press (A) to reboot your console
  3. Your console should have booted into the Luma3DS configuration menu
    • Le menu de configuration de Luma3DS sert à régler les paramètres du custom firmware Luma3DS. Beaucoup de ces paramètres peuvent être utiles pour la personnalisation ou le débogage
    • Pour les besoins de ce guide, laissez ces options sur les paramètres par défaut (ne cochez ni ne décochez rien)
    • If your console 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

Section IV - Removing MSET9

In this section, you will remove MSET9 to prevent further issues. (This will not remove the custom firmware that you just installed.)

Do NOT skip this section! If you skip it, applications may crash unexpectedly and you will encounter errors on the next page!

  1. Éteignez votre console
  2. Insérez votre carte SD dans votre ordinateur
  3. Run the MSET9 script:
    • Windows: Double-click mset9.bat
    • macOS: Double-click mset9.command and enter your password if prompted
    • Linux: open a Terminal window, cd to the root of your SD card, then type python3 mset9.py and press Enter
  4. Type the number corresponding to your console model and version, then press Enter
  5. In the MSET9 window, type 3, then press Enter to remove MSET9
    • You should see “Successfully removed MSET9!”
  6. Press Enter to close the MSET9 script

À partir d’ici, votre console démarrera sur Luma3DS par défaut.

  • Luma3DS ne présente aucune différence visuelle avec le menu HOME normal. Si votre console a démarré dans le menu HOME, elle exécute un custom firmware.
  • Sur la page suivante, vous installerez des applications homebrew utiles pour compléter votre configuration.
