Before starting this guide, we will see if custom firmware is already installed and check the current system version of your console.
#### 第一步 – 检查自制固件
1. Power off your console
1. 按住 “Select” 键
1. Power on your console while still holding the (Select) button
1. If you do not see a custom menu (your console just boots to the HOME Menu), you may proceed to the next section
If you see the Luma3DS configuration screen or any other custom menu (e.g. GodMode9, Decrypt9WIP), STOP - you already have custom firmware! [点这里继续](checking-for-cfw#what-to-do-next)。

#### 第二步 — 检查系统版本
1. Launch System Settings on your console
1. 你主机当前的系统版本将会显示在上屏的右下角(例如 “Ver. 11.17.0-50U")
#### 第三步 – 选一个方法
To find the correct method for your console, please select the model of your console and the system version you found in Section II.
{% capture noneSelected %}
System model is required.
{% endcapture %}
{% capture invalidVersion %}
This doesn't seem to be a valid system version.
{% capture methodUnavailable %}
You currently cannot hack your 3DS on this version using the main methods. If you want to hack your console, you may have to use ntrboot.
{% include consoleVersionSelect.html noneSelected=noneSelected invalidVersion=invalidVersion methodUnavailable=methodUnavailable %}
#### 其他方法
If possible, you should follow the method given by the prompt above.
以下方法需要一些外设才能进行:
1. [kartdlphax](installing-boot9strap-(kartdlphax)) - 需要另一部已破解的 3DS 并已安装了《马里奥 赛车 7》(Mario Kart 7)
1. [ntrboot](ntrboot) - 需要兼容的 DS 烧录卡
1. [安装 boot9strap(通过硬件修改)](installing-boot9strap-(hardmod)) - 需要焊接工具
