If it were only this easy to make more android users. Currently working on ss 4.8 that I'm using but should work on all others. As always I am not responsible for any damage that may occur to your phone.
root installation-(all minus quotes)
1. put bootanimation.zip on the root of your card.
2. open up console emulator and type "su"
3. then type "cp /sdcard/bootanimation.zip /data/local/"
4. type "reboot"
if all was done correctly your phone should restart with your new boot animation!
