How to disable Bootanimation on Z1

Hello everyone,

there are several threads regarding this topic but non gives the right answer (most with answers are only about CHANGING the boot animation). What I want on my Z1: Disable that Animation. The more booting messages I get the better it is. But I do not want to install some fake kernel message animation. Default Android logo would be still better than the current animation.

So is there a way to disable the boot animation to get raw booting information?

Thanks!
Best,
Fresh
