Technical Details (optional)

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.

Compatibility Notes

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.

Qué necesitas

  • The latest release of MSET9
  • 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.

Instrucciones

On this page, you will use the MSET9 script, which is used to trigger MSET9. While the script is in progress, user data will temporarily disappear but will return upon the completion of this page. If you get an error when running the script, the solution to that error can most likely be found on the troubleshooting page.

Sección I - Preparativos

In this section, you will prepare the MSET9 exploit by temporarily creating a new HOME Menu profile with no user data, and then setting up that profile with only the minimum data required for MSET9 to trigger. Your existing user data will disappear, but will come back when you are finished with this page.

  1. Inserta tu tarjeta SD en tu computadora

  2. Copy everything from the MSET9 .zip to the root of your SD card, overwriting any existing files

  3. Run the MSET9 script:

    • Windows: Double-click MSET9-Windows.bat
    • macOS: Double-click MSET9-macOS.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

    • Ensure that the correct console model and version is displayed
  5. Type 1, then press Enter to begin the process of creating the MSET9 ID1
  6. After reviewing the disclaimer, type 1 again and press Enter to accept it
  7. If you see the message “Created hacked ID1.”, press Enter to close the MSET9 script
    • Your 3DS will appear to have no data / no user-installed apps on HOME Menu. This is expected. Your data will come back at a later step
  8. Reinsert your SD card into your console
  9. Power on your console
  10. Open Mii Maker
  11. Wait for your console to reach the Welcome to Mii Maker screen, then exit Mii Maker and return to the HOME Menu
    • You may see this screen, which indicates the necessary data has been created
    • If you just reach the normal Mii Maker screen, then the data already exists. Exit Mii Maker and return to the HOME Menu
  12. Launch System Settings and navigate to Data Management -> Nintendo 3DS -> Software -> Reset (image)
    • This will not wipe any of your data
  13. Power off your console by pressing the power button then tapping Power Off on the lower screen

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

  1. Power on your console, ensuring System Settings is selected
    • If System Settings is not selected, hover over the System Settings icon using the D-Pad, power your console off, then back on
  2. Press (A) to launch System Settings
  3. Navigate to Data Management -> Nintendo 3DS -> Extra Data (image)
  4. Do not press any buttons or touch the screen
  5. 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
  6. Inserta tu tarjeta SD en tu computadora

  7. Run the MSET9 script:

  11. Reinsert your SD card into your console without pressing any buttons or touching the screen
  12. Si el exploit ha funcionado, habrás iniciado SafeB9SInstaller
    • If you get a red screen or the console gets stuck on a loading screen, follow the troubleshooting guide

Sección III - Instalar boot9strap

En esta sección, instalarás custom firmware en tu consola.

  1. Cuando se te pida, introduce la combinación de botones mostrada para instalar boot9strap
  2. Una vez completado, pulsa (A) para reiniciar tu consola
  3. Tu consola debería haber iniciado en el menú de configuración de Luma3DS
    • En el menú de configuración de Luma3DS están los ajustes para el custom firmware Luma3DS. La mayoría de estos ajustes son para customizar o para debugging
    • Para los fines de esta guía, deja estas opciones en los valores por defecto (no marques ni desmarques nada)
    • Si la consola se apaga cuando intentas encenderla, asegúrate de que copiaste boot.firm desde el archivo .zip de Luma3DS a la raíz de tu tarjeta SD
  4. Presiona (Start) para guardar y reiniciar

Section IV - Removing MSET9

In this section, you will remove MSET9 to prevent further issues and to restore your user data (games, themes, etc). (This will not remove the custom firmware that you have 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. Apaga tu consola
  2. Inserta tu tarjeta SD en tu computadora

  3. Run the MSET9 script:

    • Windows: Double-click MSET9-Windows.bat
    • macOS: Double-click MSET9-macOS.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
    • The current state should display Injected
    • If you have already removed the trigger file (or never injected in the first place), the current state will show Ready, skip to Step 6
  5. Type 4, then press Enter to remove the trigger file
    • You should see “Removed trigger file.”
  6. Type 5, then press Enter to remove MSET9
    • You should see “Successfully removed MSET9!”
  7. Press Enter to close the MSET9 script

En este punto, tu consola arrancará en Luma3DS por defecto.

  • Luma3DS no se ve distinto del Menú HOME normal. Si tu consola ha encendido y muestra el Menú HOME, está ejecutando custom firmware.
  • En la siguiente página, instalarás aplicaciones útiles de homebrew para completar la instalación.
