Before installing the drivers, you need to disable signature verification on your system because these drivers are not signed. To disable signature verification on your pc search google.
Two of the most popular spreadtrum cpu used in smartphones are the SC6820 and SC8810. So many phones out there run on these chips e.g Itel, MBO, Mhorse, Samsung galaxy clones{Spd} etc.
