PS:

Tip to recover ESP8266 board if it can not be loaded.
I just use luftdaten-tool_windows_amd64.exe loader - and prepare breadboard with ESP and D8+D7 connected to +3.3V pins. Then start downloading - loader will waits for respons for more than 10 seconds and duringthat time I just unplug wires from D8 and D7. Miracle - it loads and starts to work fine!
