I know there is already one official black bootanimation by mexxxico (thanks to him) on this thread : http://forum.xda-developers.com/show....php?t=1555280
but rendering is gray, no black... mine is really black as you can see on the screenshot below !
On the left the bootanimation by mexxxico and on the right mine.
I also made the downanimation.
This is not a complicated job but I had to modify pngs one by one on photoshop (60 for the bootanimation and 60 for the downanimation)
I also modified the splashscreen as ardax asked (the right on screenshot) :
(zip made with touch of jobo's splashscreen generator), thanks to him.
