Xiaomi Gateway v3 cannot connect to WiFi after update

I have Xiaomi Gateway v3 (ZNDMWG03LM) with the following issue: recently updated at the last firmware 1.4.6_0012. After that GW didn’t start, I followed the connection procedure on the serial port (described on the forum for V2) and from the logs during boot I came to the conclusion that the WiFi connection does not start, the message is: br0: port 2(wlan0) entered forwarding state.

How can I start the WiFi interface?, physically it works, if I run the wifi_start.sh script from /usr /app/ bin/, it starts in AP mode.

-ifconfig wlan0 up responds with #br0: port 2(wlan0) entered forwarding state

Thank you.
