[Q] HTC Endeavoru One X Bootloader help

Hi Guys, I have this old HTC OneX with following details. I am trying to load the latest Cyanogen ROM, and able to unlock, put a latest recovery ROM, but when I attempt to upgrade, I get an error message which means the HBOOT on the device needs to be atleast v1.28 or higher. Can anyone help me to upgrade the HBOOT. I also have stock v3.??? ROM for this device, but even that will not successfully upgrade, for some strange reason.
