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?

The upgrade firmware on the ESP8266 is hardcoded. Attempting to reflash it with known good firmware should restore functionality.

Make sure you have the correct firmware depending on the version of the board you have, the family seems quite big: esp8266 wiki

There's nothing stopping you from experimenting and flashing different versions until you find the one that works.

Make sure that GPIO0 is not shorted to ground. Otherwise, try to reflash the firmware and when finished, leave GPIO0 floating to get out of firmware upgrading mode.
