name it bootanimation.zip and place it in the system/media folder. should run fine
edit: no luck. after extracting the zip, i noticed another the first file is named bootanimation as well. extracted those contents and rezipped them/named it bootanimation.zip. therefore once you open the bootanimation, it goes straight into the desc and the part0 folder. still no luck. ill dig around and see whats going on. no promises as i am no good at coding but we'll figure it out. stock boot ani sucks lol.
