How would you change the default Android boot animation? I am attempting to change my boot animation on a rooted Xoom with Android 3.2.

I've got the files in part0/ the desc.txt looks like

1408 880 24
p 0 0 part0


I made the images 512x256 since this is what the Honeycomb boot animation had.

After I copy the bootanimation.zip image to /system/media/ and reboot I get just a black screen. I've tried 777 and 644 permissions on this file.

Any ideas how to not get a black screen?
Looks like this was a corrupt zip problem.. from linux zip tool you must be using the -0 switch to 'store'.
