How to bypass the pattern lockscreen of any android phone

To remove the pattern lock of the android devices, you gonna need a computer running any linux distro, as of my case ubuntu 13.04. Just follow the following steps

1. Open the linux terminal and type
    $sudo apt-get install android-tools-adb
   and let it install

2. When it is installed, connect the android device to the computer.

3. Type
    $adb devices
   a will device will be shown and if not then make sure that USB Debugging is switched ON, on the android devices, probably located in the developer options inside the settings(on device on or after android 4.0)

4. Now the device is shown, then type
    $adb shell
    $su
    #cd data/system
    #rm *.key;
    #exit
    $adb reboot

5. Now your device will be rebooted.

6. Now try any pattern, the device will open.

If after the step, $su, the $ doesnot changed to #, or a error pops up, it means that your device is not rooted. Fortunately, methods are there which can unlock the phone, even if the device is not rooted, that I will write about next time.
