I don't have any machijnes runnijng Linix atm so I'm not ablle to look through it there. As far as on the build, I noticed that they stuck the bootanimation in /system/bin for some reason so lemme take a look through there.
Edit: Or is that where the default bootanimation has always been lol. I'm going to grab something to eat.
Thought it was usually in system media?
Yes --> \system\media\bootanimation.zip
True, but if you delete whatever is in there, the system falls back to the default animation which is just the word "Android". This is the one I was talking about. This build doesn't have any custom boot animations so it uses what's in /system/bin.
