Here’s what you need to do get the ‘Google Evolved’ boot animation onto your device:
Step 1: Install a root file explorer to your phone if you don’t already have one. Free options like ES File Explorer can be downloaded from the Play Store.
Step 2: Launch the file explorer app and navigate to the /system/media directory. Copy the ‘bootanimation.zip’ file inside and paste it to another folder. This is optional, but it’s always worth having a backup just in case the worst was to happen.
Step 3: Download the ‘Google Evolved’ bootanimation.zip to your phone.
Step 4: Copy the downloaded file from the Downloads folder, paste it to /system/media, allowing the file explorer to overwrite the existing file. Remember, this directory isn’t the same for all devices. You might have to look up where your device’s bootanimation directory is.
Step 5: Once the file is copied over, make sure that its permissions are set to 0644. Note that copying to root directories requires root access. If your device isn’t rooted, and you have the Android SDK set up on your computer, you can use ADB to push the bootanimation.zip file from your computer to the /system/local directory.
Step 6: Reboot your device and you’re set!
