I am on the latest CM11 on the i9082. Over the past week I tried changing the bootanimation to a custom one of resolution 800x480. However each time, I got a black screen. The phone did boot normally, albeit without any animation. Upon further inspection, the bootanimation.zip in system/media has .jpg format files where as most bootanimations have .png format files. Is this why no custom bootanimation would not work?Thanks in advance.
