the goggles have 3 different hardware due to global chip shortage, before flashing the firmware, user must check their hardware version of the goggles in the system menu. 

V1 orignail

V2 60FPS DVR, if user bought the 60FPS DVR kit, the V1 goggles will upgrade to V2, and firmware also need flash to V2.

V3 new MCU due to chip shortage. due to the performance is same, we didnt name the goggles V3, only hardware is named V3.

Flashing the wrong firmare will cause the DVR not working or menu not working!!!

How to tell the hardware version

In settings-system menu-Firmware version

if FW1: Start with V1.3.9,  means  V1 hardware

If FW1: Start with V2.3.9,  means V2 hardware,
