My Solution

By default, Android powered HTC Smartphones comes with Locked Bootloader and default Recovery firmware which is not so much useful and handy. ClockWorkMod recovery is a very simple and feature rich recovery software which gives many features like Backup and Restore, Mount as USB etc which are mostly not available on stock Firmware or recovery software.

           To install CWM Recovery, you first have to Unlock your devices bootlaoder and then Root your phone.
