Hi
thank you hdrut
The problem of updating the firmware is automatically solved i used the same configuration .
GPIO0 --->GND
CH_PD--->VCC
i tried many times updating it but nothing happened and at one try all of sudden the firmware got updated i was using firmware(AI-v0.9.5.0 AT Firmware) and was using esp8266_flasher for flashing.So still I dont know what is the reason for it to update as everything remained same.

just checking... Have you :
- Do you have a good 3.3V input to VCC?
- CH_PD pin to VCC.
- GPIO15 to GND .
- GPIO2 to VCC .
- GPIO0 to GND.
After pulling down GPIO0 you should either reset the module or pull down CH_PD to enter bootloading mode.
Also check RX-TX connections to make sure they´re right: RX from ESP -> TX of PC, and vice versa.
Have you grounded the serial port as well?
Let me know if this helps.
greetings
