As stated in the first post, I have only tested this on a Verizon TP2, the file names could be different on the Sprint.

I can try to help figure it out though.

During startup and shutdown are you seeing both of the sculls (Startup and Shutdown) but just not animated?
If that's the case then Sprint may use a different type of animation file.

If you don't see either of them then I'm gussing that the file names are different on the Sprint phone.
