These are the official Google Pixel boot animation files, from Android Pie. To install them you'll need to have root access on your devices, as well as a root file explorer.
•Download the zip of your choice
•Change the name of that zip you had downloaded to "bootanimation"
•Go to /system/media
•Replace the bootanimation.zip in there with yours
•Reboot your device
Soon i'll bring the Pixel boot logo too. It will require flashing it with TWRP. Also i'm working on another custom boot animation, so stay tuned!
