I was able to change the boot animation before Froyu using the procedure at http://androidforums.com/tips-tricks-evo-4g/109120-how-install-new-boot-animation-without-root.html . After Froyo, I've tried to push the zip file as VZW_bootanimation.zip and bootanimation.zip to both /data/local and /system/customize/resource (I can't write to that location, I think it's for rooted phones only). None of these four options worked. What am I missing? That native boot animation is nasty. Thanks in advance.
