[Q] HTC Evo 3d Sprint can't boot/ soft or hard brick? topic

Please i have HTC Evo 3d and I've never had any problem until now. When i try to switch ON the device, it shows the HTC logo for 3 seconds then restart and keep doing the same cycle over and over again until it run out of juice. I tried accessing recovery but i had no luck.
I unlocked the bootloader at HTC dev. Below is my bootloader info.
