Don’t Brick Your WalkSnail Moonlight | Easy Firmware Update Guide
Updating the WalkSnail Moonlight Pro firmware doesn’t need to be complicated. In this video, I walk through the full Caddx Avatar VTX firmware update process, including how to download the latest release, format the SD card correctly, bridge the Moonlight boards, and safely flash the VTX without bricking it.
We also cover the 8-second link button method, why the green and red status LEDs matter, and the biggest mistake to avoid during the update: disconnecting power too early. Recent Moonlight-specific releases even added a VTX-only upgrade path, making the process cleaner for Moonlight hardware.
If you’re running WalkSnail Avatar, Moonlight Pro, Avatar HD VTX, or compatible goggles, this guide will help you keep your FPV system updated, stable, and ready for your next flight.
If this helped, drop a comment below and let me know what firmware version you’re running.
