The update is of 244.2MB and can be installed on a pure Stock device using the Adb Sideload or you can give it a try to any device with Custom rom installed.

The methods involved in flashing custom recoveries, roms and rooting your phone are highly custom and may result in bricking your device, and has nothing to do with Google or the device manufacturer that is HTC in our case. Also rooting your device will void its warranty and you will be no longer eligible for any kind of free device services by the manufacturers/warranty providers. In case of any mishap we may not be held responsible.
