<summary><em>Technical Details (optional)</em></summary>
[MSET9](https://github.com/zoogie/MSET9) is an exploit for the System Settings application developed by [zoogie](https://github.com/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)](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](https://wiki.hacks.guide/wiki/3DS:Alternate_Exploits).
{: .notice--warning}

### Wat je nodig hebt

* The latest release of [MSET9](https://github.com/hacks-guide/MSET9/releases/latest)
* Any 3.x version of [Python](https://www.python.org/downloads/) **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.

### Instructies

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](troubleshooting#installing-boot9strap-mset9) page.
{: .notice--info}

#### Deel I - Voorbereiding

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. Plaats je SD kaart in je computer
1. Copy everything from the MSET9 `.zip` to the root of your SD card, overwriting any existing files

    ![MSET9 root layout](/images/screenshots/mset9/mset9-root-layout.png)
    {: .notice--info}

1. Run the MSET9 script:
{% capture mset9-chorus %}
    + **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
{% endcapture %}
    {{ mset9-chorus }}

1. Type `1`, then press Enter to begin the process of creating the MSET9 ID1
1. After reviewing the disclaimer, type `1` again and press Enter to accept it
    + If you get an error, check the [troubleshooting](troubleshooting#installing-boot9strap-mset9), then try again
1. 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

1. Open Mii Maker
1. Wait for your console to reach the [Welcome to Mii Maker](/images/screenshots/mset9/mii-welcome.png) screen, then exit Mii Maker and return to the HOME Menu

    + If you just reach the [normal](/images/screenshots/mset9/mii-existing.png) Mii Maker screen, then the data already exists. Exit Mii Maker and return to the HOME Menu
1. Launch System Settings and navigate to `Data Management` -> `Nintendo 3DS` -> `Software` -> Reset ([image](/images/screenshots/database-reset.jpg))
    + This will not wipe any of your data

    ![Image: MSET9 setup](/images/screenshots/mset9/mset9-ready.png)
    {: .notice--info}

    + If the window says [Not ready - check MSET9 status for more details](/images/screenshots/mset9/mset9-not-ready.png):
        + Type `2`, then press Enter to check the MSET9 status and follow the directions indicated
        + Once you have resolved the issue, return to Section I Step 14
        + For more information, check the [troubleshooting](troubleshooting#installing-boot9strap-mset9) page
1. Type `0`, then press Enter to close the script
1. Stop je SD-kaart terug in je console

#### Section II - MSET9
