I received some valuable guide to root my phone and I have some questions about this. In the guide it says I have to install certain Android drivers before going for root. Please let me know whether I have to install these drivers to my PC or my Phone? Also let me know the specific drivers to be installed. Secondly, I have another question. Suppose, if by chance my phone cannot root according to the guide, will I be able to restore my phone to the original status? I am expecting an early reply.
