Install Android 2.1 UI on Nokia S60v5 mobile

I was searching for a solution to run android on my Nokia 5230. I found some YouTube videos with tag Android and Nokia. After a long search I found some solution to tweak the user interface of Nokia with an Android. Here are the steps to change Nokia UI to an Android UI on Symbian 60V5. Remember this will change only the User interface. You can always uninstall.
