Prerequisites

  • Before you start, it is always advisable to take a back up of your phone’s data. Backing up your contacts is easy and you can back up all your contacts to your phone’s SD Card.
  • To back up your applications, I recommend you to use ASTRO File Manager which also allows cloud storage.
  • Make sure your phone’s batter has a minimum of 60% charge.
  • Enable USB Debugging. To do this, go to Settings>Applications>Development and make sure USB Debugging is checked.
  • Latest Samsung drivers (can be located via Google easily)
