 _It appears that [SonOTA](https://github.com/mirko/SonOTA) may work again [with Sonoff firmware v2.0.1 or greater](https://github.com/mirko/SonOTA/wiki#known-working-configurations). This needs to be verified for this specific device._ To get it working you can simply plug it to mains, once it's powered up, press and hold the button that's closer to the Wi-Fi logo (you'll hear a beep sound). Keep holding it until you hear that beep for the second time. Now let go. The Wi-Fi light should blink in pairs of 3. Now repeat the procedure (Press and hold until you hear the beep 2 times). Now you should be seeing the Wi-Fi logo flashing rapidly. You can proceed to try and flash with [SonOTA](https://github.com/mirko/SonOTA) now.
