如果你的3DS之前已经破解并安装了基于虚拟系统（EnuNAND）的自制系统（CFW），请务必注意本教程仅适用于真实系统（SysNAND），并且教程内的所有步骤都应当在你的真实系统（SysNAND）上进行。 注意EmuNAND和RedNAND是[同一概念](http://3dbrew.org/wiki/NAND_Redirection)的两种略微不同的实现。

#### 操作指南

##### Section I - OCS

1. Press (A) to begin
1. Wait for the downloads to complete
1. Wait for the exploit to run
  + This may take several tries
  + If it freezes, just force the console to power off by holding the power button, then relaunch OCS to try again
  + If you get a "PM INIT FAILED" error, try replacing the `safehax.3dsx` file in the `/3ds/` folder on your SD card with the one from the [r19 release of safehax](https://github.com/TiniVi/safehax/releases/tag/r19)
1. If the exploit was successful, you will have booted into SafeB9SInstaller

1. When prompted, input the key combo given to install boot9strap
1. Once it has completed, press (A) to reboot your device

##### 第三部分 - 设置 Luma3DS

1. Your device should have rebooted into the Luma3DS configuration menu
