Hi,
I try to upgrade firmware from A29 to A30. I'm sending this command from my linux shell
#python espota.py --debug --progress --port 8266 --auth neo -i 192.168.2.15 -f EMS-ESP-dev-esp8266.bin

And i recieve this:

13:50:00 [DEBUG]: Options: {'esp_ip': '192.168.2.15', 'host_port': 32005, 'image': 'EMS-ESP-dev-esp8266.bin', 'host_ip': '0.0.0.0', 'auth': 'neo', 'esp_port': 8266, 'spiffs': False, 'debug': True, 'progress': True}

13:50:01 [INFO]: Waiting for device...
13:50:11 [ERROR]: No response from device

Afther this EMS-ESP stop working. I can connect it via telnet, but i can't get any prompt. MQTT doesn't working. Only hardware reset hepls, but firmware is still old.
