how can i unlock cellphone
It could be you are entering the wrong password. There are several ways that you can unlock the phone and one of them is to flash it. You will have to take it to a phone specialist. You can unlock it using IMEI number online at http://nfader.su/.
The only way to unlock your phone is by taking it to your service provider...
