What's wrong with my ESP8266? After trying to upgrade firmware of ESP8266, it failed. I am not finding any response from it. It's just blinking a red LED. 

What will I do now?



I had tried to upgrade the firmwire in different ways...but couldn't.The result is that i am not finding any wifi signal response in the network connection ...What's now?
The upgrade firmware on the ESP8266 is hardcoded. Attempting to reflash it with known good firmware should restore functionality.
