The first thing I wanted to do after I root my HTC Sensation was to change the boot animation from 'screaming' white to black.
So for those who want the original, but black HTC boot animation they are free to take it from here
As you wish, thread updated with matching downanimation
Adding the original boot animation & down, if someone needed
Added splash_screen (splash.img)
Flash it with adb.
(adb reboot bootloader
fastboot flash splash1 splash.img)
