In this Tutorial 1, you will learn on how to flash Ai-Thinker firmware (3rd party manufacture) which is the built-in firmware.
You can refer Tutorial 2 if you want to flash firmware using the latest Espressif SDK firmware (Original designer of ESP8266 chip). Espressif firmware is the most frequent update. Refer link below.
