The standby and shutdown images and the bootanimation might be sensitive to settings.
I can't guarantee this will work but they seem to be the default locations if you have disabled KCB.
Code:
pm disable com.onyx
Code:
/system/media/bootanimation.zip
/data/local/assets/images/shutdown.png <-- This image is in landscape
/data/local/assets/images/standby-1.png <-- These are in portrait
/data/local/assets/images/standby-2.png
/data/local/assets/images/standby-3.png
