Not sure if anyone knows this but under
/system/media
you have 3 boot animations,
bootanimation.zip
bootanimation_virgin.zip
bootanimation_boost.zip
I renamed the bootanimation.zip to something else, and changed bootanimation_virgin.zip to just bootanimation.zip and rebooted now I have a virgin mobile boot animation instead of the lg one. I'm sure you could find different ones online and use those as well. You can do it for the shutdown as well. You have to be rooted for this to work.
