Although you don’t normally see the boot animation very often, especially on a device with a pretty stable ROM, the inevitable and occasional (or perhaps frequent) reboot prompts you to sit through the whatever flashy wave, colorful pulsating icon, or even a bland Android mascot for those 10 or so seemingly “eternal” seconds. If you’re looking for an easy way to make it that much more interesting on the Moto X, you may want to check out Bootiescreen.
Developed by XDA Forum Member geeksunny, Bootiescreen does exactly what the ‘owners info’ option in Android settings does to the lock screen: inserts a custom text message into the boot animation. Because the app changes clogo, only Moto Xs that are rooted and have a locked bootloader will be able to use Bootiescreen. Unlike ‘owners info’ however, you are allowed some flexibility and customization, including:
the text font (can only be chosen from system fonts as of now)
the location of the message on the boot animation
Geeksunny has provided a simple method of personalizing a custom boot screen graphic with a message in the original post, but has plans to integrate a more direct method of installing and personalizing custom boot animations in a future update. Additionally, Bootiescreen is open source, so you can tinker with the app all you like.
