What it does

Flashes a new application image using ESP32 Update APIs—typically from a .bin on SD or a path the UI offers (OTA details depend on build).

How to use

1. Copy the correct firmware .bin for your board to SD (path per on-screen browser).
2. Full battery / stable USB power; do not bump the cable.
3. Open Update Firmware, select file, confirm.
4. Wait until success; device may reboot automatically.

Warning: Wrong image or power loss during flash can brick the device until USB serial flash recovery.
