Section IV - safecerthax
In this section, you will enter Safe Mode (a feature available on all 3DS family consoles) where safecerthax will be triggered, which will launch you into the boot9strap (custom firmware) installer.
- With your console still powered off, hold the following buttons: (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A), and while holding these buttons together, power on your console

- If the console freezes or crashes, force power off the console, then retry this section
第五步 – 安装 boot9strap
In this section, you will install custom firmware onto your console.

- If a step on the lower screen has red-colored text, and you are not prompted to input a key combo, follow this troubleshooting guide
- Once it is complete, press (A) to reboot your console
- Your console should have booted into the Luma3DS configuration menu
- Luma3DS 配置菜单用于设置 Luma3DS 自制固件的可选功能 其中有许多功能可用于个性化或调试
- For the purpose of this guide, leave these options on the default settings (do not check or uncheck anything)
- If your console shuts down when you try to power it on, ensure that you have copied
boot.firmfrom the Luma3DS.zipto the root of your SD card
- 按下 “Start” 键保存设置并重启
At this point, your console will boot to Luma3DS by default.
- Luma3DS does not look any different from the normal HOME Menu. If your console has booted into the HOME Menu, it is running custom firmware.
