1. Complete the initial setup process for the launched game until you reach the main menu
    + Select the left option whenever prompted during the setup process
    + If you encounter an issue while doing this section, [check this troubleshooting guide](troubleshooting#installing-boot9strap-fredtool) for your issue
1. Using the touch-screen, select the large left box, then select the box with an SD card icon
1. Once the menu loads, select the face icon, then the bottom right icon to continue
1. Press (X) or (UP) on the D-Pad depending on which is shown on the top screen
1. Select the second button along the top with a film-reel icon
1. Scroll right until reel "3/3" is selected
1. Tap the third box with the letter "A" in it
1. Scroll left until reel "1/3" is selected

{%- if include.method == "dsinternet" %}
    + If you miss this step, the system will exit to HOME Menu instead of installing boot9strap and you will need to open Nintendo DS Connections and start over from the beginning of this section
{%- elsif include.method == "dsdlp" %}

1. Press (A), then press START and SELECT at the same time to begin the process
1. Once completed and the bottom screen says "done.", exit b9sTool, then power off your console
    + You may have to force power off by holding the power button
    + 如果你的主机在你尝试开机后直接自动关机了，请确认你已经从 Luma3DS `.zip` 中复制了 `boot.firm` 文件到你的 SD 卡根目录中
