Just try with the below steps to hardreset your phone:-

6.Then use vol- key to move the cursor to " yes-delete all user data" , press menu key to select it.
7.Then choose reboot system now ,you phone will reboot itself.

What I have found through researching the problem is that you will need to reset your phone.

First go here and download the Android SDK

http://developer.android.com/sdk/index.html


Unzip the android-sdk-windows folder and place it on the root of your C: drive.

Then open up a blank command prompt window

(in windows 7 Open the Start Menu.Click on All Programs, Accessories, and on Command Prompt., or


To open a Microsoft MS-DOS command prompt shell window, click the Windows Start menu (located at the very lower-left corner of your computer's desktop) and select "Run...".


Then if you are using Windows XP or Vista or Windows 7, type cmd into the Run box and click "OK". You could also type cmd.exe

Otherwise, if you are using an older version of Windows, type command into the Run box and click "OK". You could also type command.exe

Once your command promt window is open

type cd\android-sdk-windows.

Then type cd tools.

Now boot up your phone into usb fastboot mode by starting with it powered off,

hold volume up, end, trackball and power all together.

You should see some text on the screen with "USB Fastboot Mode" at the top of the screen.

Plug it into your computer using the USB cable.

Now back at the command prompt window type fastboot -w.

This will erase the user data and cache partitions and your phone will be factory reset.

Once that is done it will give you a success message.
type reboot into the command prompt window and you will be good to go.

Hope this helps
