krazyates use the solution that i posted. will fix your problem
One thing I would add is links to other topics on this forum to things like, how to root, using adb, how to install busybox if needed, how to install metamorph if needed, things like that. =) Also let people know that if they want to change just the bootanimation they dont need to have root and how to do it if they dont.
Boot Animation WITHOUT ROOT, but assuming you know basic knowledge of ADB:
1. Grab your BA and drop it in your ADB Tools folder, wherever it may be.
2. Open cmd.exe(type cmd in run if your on xp, on Vista and 7 type cmd in search)
3. cd to your ADB Tools folder. (example: my path is cd c:\adb\tools, yours is probably different)
4. Type "adb push bootanimation.zip /data/local"
5. Type "adb reboot" to reboot your phone.
6. Enjoy your new BA.
