Click Load Firmware [Online] unless you are loading a custom firmware.
If you are loading a custom firmware, click Load Firmware [Local] and browse to the .hex file.
Once you have loaded the firmware the Flash Firmware button will become available.
Click Flash Firmware
The flash process will go through several phases taking around 20-30 seconds. Once it completes, you will be kicked out of Boot Loader mode, unless you had to hard solder your boot button.
You are done flashing, restore your BetaFlight configuration.
The video below shows this process.
The reason I was forced back into DFU/Boot loader mode at the end of this video after flashing was due to me having to solder the boot “pins” due to flashing the wrong firmware. I had to desolder my boot pin in order to boot into BetaFlight on the right firmware.
