### Required Reading

Different device models and versions will require different steps to achieve the end goal of boot9strap Custom Firmware. 下面的一系列页面将会帮助你针对你的设备找到适合的开始方案。

请点击对应你设备的图片，进入相应的教程页面。 图片中机器的颜色可能会不同，但是请特别关注按键的布局和每台机器的特点，确保你选择了正确的机型。

如果你已经破解过你的3DS，并安装了基于EmuNAND的自制系统，请在SysNAND上进行本教程的所有操作。 Replace any files that already exist. Your data will be transferred from EmuNAND to your new B9S install at the end. If you use menuhax, you should [clear Home Menu's extdata](troubleshooting#clear-home-menu-extdata) to remove it before beginning.

This page is for instructions on how to install boot9strap to a *stock* 3DS or 2DS. If you already have arm9loaderhax installed and are looking to update to boot9strap, follow [A9LH to B9S](a9lh-to-b9s).

There have been reports of a wave of bans being handed out to CFW users by Nintendo. To protect yourself, please do the following steps before starting this guide:

1. Go to System Settings, then "Internet Settings", then "SpotPass", then "Sending of System Information"

1. Exit the System Settings
1. Go to your Friend List (the [orange Face Icon]({{ "/images/friend-list-icon.png" | absolute_url }}) in the top row of your Home Menu)
  + If you receive an error and are kicked out of the menu, the Friend List setting is either already disabled or your console cannot connect to Nintendo's servers (due to a ban or connection issues)
