  • Users make sure they have installed USB drivers on the PC, or else your phone (Samsung Galaxy S5) smartphone will not be recognised by the computer.
  • Make sure your device has more than 80% battery, or else there is chance of smartphone getting temporarily bricked if the installation process is interrupted mid-way.
