    Thanks for the tutorial. Before trying this method, I would like to know if
    1. This method will factory reset the phone?
    2. Lock the boot loader again?

    Thanks

      1. No, its just root your phone, your data save..
      2. Its automatically lock the bootloader again after your phone rooted, reboot and turn on prperly
