Flash the correct firmware. – Majenko Sep 24 '16 at 17:49
    
You are missing that this is the Arduino SE. You might get better answers on the EE SE which covers ESP8266 – Matt Sep 26 '16 at 12:34

AT commands are executed by the AT interpreter firmware. If you've been attempting to flash other firmware to the ESP8266 module, there is no longer any code in it that interprets AT commands. If you want to it to respond to AT commands again, you'll need to re-flash it with that firmware.

You need to reflash the "AT Firmware" you probably overwrited. Just follow the instructions in the Espressif board to get the latest one using their "Flash Download Tool".
