I believe you need an unlocked bootloader first, if your device has an unlocked bootloader then:
If you have the Android SDK platform downloaded and installed on your PC then just download a custom recovery and place it in the platform-tools folder.
Open a command prompt: Either open one and change directory to platform-tools folder(where recovery is) or hold shift, right click in folder and then click on "open command prompt/window here".
Connect your device to your PC(You should have all HTC drivers installed, can be done with HTC sync manager).
Type: adb devices
should show you your serial number for the device then you know it picked it up.
Type: adb reboot bootloader
- Phone will then reboot into bootloader mode.
Type: fastboot boot name_of_custom_recovery.img
Custome recovery of your choice(TWRP or CWM Philz) will then boot up, flash the root program(SuperSU for example) reboot phone.
