  1. Rooting process went successful, it took 3 minutes to root the smatrphone. Hats off guys

  2. I’m new to android and smartphones but I do have a basic know how of things. I recently bought Galaxy S Duos. Can that be rooted to use the Jelly Bean 4.1.2? If yes, then how?

    • Rooting is done not to use another firmware.. Rooting allows you to install certain apps which require root permission to work.. Galaxy S Duos come with Ice Cream Sandwich i.e. Android 4.0.3 or 4.0.4 firmware.. Unless there is official update of Jelly bean available, you won’t get it..
