Make sure DFU driver has been installed. Check out “Install DFU Drivers” in this page

Connect the Receiver USB to computer while holding the boot button in.

Select USB
USB1 and click Refresh
Connect
select “Erasing & Programming”
Tick all sectors and click “erase selected sectors”
Browse firmware (hex or bin file) related to the hardware.
Click “Start Programming”
After programming, unplug USB and plug USB back in. If red LED blinks at 2Hz, the receiver is waiting for connecting with transmitter.

*** You can also flash it via INAV or BetaFlight configurator, load firmware local, just like flashing a flight crontroller.
