    2. From list of options, choose Flashmode, Fastboot and Xperia V drivers to install.
  5. Have your phone charged so it has at least over 60 percent of its charge. This is to make sure your phone doesn’t run out of power before the process is through.

  7. Enable USB debugging mode on your phone through one of these two methods.
    1. Go to Settings>Developer Options>USB debugging.

Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device.  Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers.  Be responsible and keep these in mind before you decide to proceed on your own responsibility.  In case a mishap occurs we or the device manufacturers should never be held responsible.
