Switch off your phone and Do a restart- Get your data cable and connect to the PC- Suddenly you will see the "Mass Storage Mode" Selection page.- Then you may able to go the upper task menu and you may able to activate Wi-Fi or Data.Thereafter you can unlock the phone using the Google credentials.This was worked for me several times.
I had the same problem. I bought two new batteries before I figured it out. The three brass connections on the phone that normally touch the battery tend to curl up after several battery pulls like a finger curls up into a fist. After you remove the battery, gently scrape the brass leads on the phone with your fingernail until they extend out onto the chrome area beneath. If it doesn't work then try again. The charging leads are not making the connection to the battery because they are bent or curled up into the phone.If it still doesn't work then there's something else wrong.
Hi,
Welcome to Fixya. Unlocking Phone to be used to other network can cost you due to the special software that they're using even the phone is not connected to a computer to flash it. All you need to provide is the IMEI of the phone and after a few minutes you will have the code.
You can try to check the link below for unlocking of you phone.

Cell Phone Keeps Shutting Off Vibrations on dirty battery contacts could be the cause of this problem. Remove the battery and clean the battery contacts with methylated spirits and the battery contacts in the cell phone.
