On this page you can reflash or update our products to the latest factory firmware using ESP Web Tools — directly in your browser. Requirements: Google Chrome or Microsoft Edge over HTTPS.
Flashing from this page writes the factory firmware image to your device. All current settings, Wi‑Fi credentials, and local configurations on the device will be erased. Make sure you have any required credentials at hand to reconfigure after flashing.
