you can copy/paste files to the phone in the followingstructure:-
first 4 files are to do with boot animation, next 2 are the boot and shutdown sounds and the last 2 are shutdown animation.
once you copy them accross, you msut set permisions on all files to rw-r--r--
an example of a flashable zip is attached, and this just saves the bother of doing it all manually. just flash it from custom recovery (and maybe need to wipe dalvik and cache, I've heard that changes to system files on odex roms require this?)
p.s. the attached file is the s5 boot animations and sounds. i didn't make it....can't remember where i got it, so apologies to the creator
