#### 步骤概览
{% capture notice-2 %}
The file `boot.firm` is what is launched by boot9strap itself after it finishes loading off of NAND, and can be any valid arm9 payload in the FIRM format. This file can be replaced at any time, although Luma3DS allows for the launch of other arm9 payloads in the FIRM format using the Luma3DS chainloader.
+ Delete both of these files after updating your device later in these instructions
1. Reinsert your SD card into your device
##### Section II - Configuring Luma3DS
1. Boot your device to enter the Luma3DS configuration menu
+ If you get a black screen, [follow this troubleshooting guide](troubleshooting#ts_sys_b9s)
1. 使用方向键和A键来启用以下设置：
+ **"Show NAND or user string in System Settings"**
1. 按下(Start)键保存设置并重启
+ 如果出现黑屏，请照常进行接下来的教程
##### Section III - Updating the System
If, before following this guide, you already had an EmuNAND setup and would like to move the contents of your previous EmuNAND to your new SysNAND CFW, now is the time to [follow Move EmuNAND](move-emunand) instead of doing the first nine steps in this section.
{: .notice--info}
1. Update your device by going to System Settings, then "Other Settings", then going all the way to the right and using "System Update"
+ Updates while using B9S + Luma (what you have) are safe
如果这一步出错，则将DNS设置改为”auto”（自动）
+ If this still gives you an error and your NAND is below 9.2.0, [follow 9.2.0 CTRTransfer](9.2.0-ctrtransfer), then try updating again
##### Section IV - Injecting FBI
1. Reboot holding (Start) during boot to launch the Luma3DS chainloader menu
1. Launch GodMode9 by pressing (A)
1. Navigate to `[0:] SDCARD` -> `cias`
1. Press (A) on `FBI.cia` to select it, then select "CIA image options...", then select "Mount image to drive"
1. Press (A) on the `.app` file, then select "NCCH image options", then select "Inject to H&S"
1. Press (A) to unlock SysNAND (lvl1) writing, then input the key combo given
You can now hold (Start) on boot to launch the Luma3DS chainloader menu (note that the Luma3DS chainloader menu is only displayed if there is more than one payload detected).
You can now hold (Start) + (Select) + (X) on boot to dump the ARM11 bootrom (`boot11.bin`), the ARM9 bootrom (`boot9.bin`), and your console unique OTP (`OTP.bin`) to the `/boot9strap/` folder on your SD card (note that this will not have any kind of prompt or message).
