A member of XDA Developers, Junior Passos, has created an exclusive and very innovative bootlogo and boot animation for Motorola Moto X (2014). After watching the video of the boot animation, I was not able to resist myself from trying it in my Moto X (2014).
To have this boot animation, you need to have a rooted device with TWRP installed. Then you can download the zip file from the link provided at the bottom and can flash it via TWRP. It is quite simple. After the reboot you will be able to see this eye candy and creative bootlogo and boot animation.
Before proceeding we recommend you to have a complete backup of your ROM via TWRP, so in case of any error you can restore your ROM. I tried it in my Moto X (2014) with stock rooted Android 5.0 Lollipop and it worked great.
In case, you want to revert back to the original boot logo and animation, then you can flash this zip file via TWRP.
