How to update the EdgeTX Radio transmitter firmware

Read the release notes first — firmware changes can require re-doing your config or calibration.
Use the project's own installer where it has one: a web flasher over USB, or an over-the-air update in its web UI.

Always download firmware from the manufacturer or project itself. Firmwarely links out; it never hosts firmware.
