<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.

### Instructions

#### Section I - Prep Work

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**
1. Open Mii Maker
1. Wait for your console to reach the "Welcome to Mii Maker" screen, then exit Mii Maker
    + You may see [this screen](/images/screenshots/mset9/mii-extdata.png), 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
1. Power off your console
1. Insert your SD card into your phone/tablet/computer
1. Copy everything from the Release `.zip` to the root of your SD card, overwriting any existing files:
    + Open ZArchiver
    + If prompted, [allow ZArchiver to access files on your SD card](/images/screenshots/mset9/zarchiver-allow.png)
    + Navigate to where the downloaded MSET9 Release `.zip` is located ([likely in the Downloads folder](/images/screenshots/mset9/zarchiver-zip-location.png))
    + Select the Release `.zip`, then select "Extract..." ([image](/images/screenshots/mset9/zarchiver-extract-1.png))
    + Navigate to your SD card, then tap the blue 'down arrow' icon to extract the files to the root of your SD card ([image](/images/screenshots/mset9/zarchiver-extract-2.png))

1. If "Setup MSET9" is [highlighted](/images/screenshots/mset9/setup-mset9-highlighted.png), MSET9 is ready to be injected. Close the MSET9 Installer for now
    + If "Check Again" is highlighted, there is a problem that you need to resolve before you can use MSET9. Refer to the [troubleshooting](troubleshooting#installing-boot9strap-mset9)
1. Reinsert your SD card into your console
1. 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!
