How To Add Custom Boot Animations To Any Samsung Android Device

Step 1: Using a root-level file explorer on your Android, mount the system as read-write and navigate to /system partition.
Step 2: Copy the bootanimation.zip file that you wish to use at this location in your device:
/system/media/bootanimation.zip
Step 3: Now, put the hack ZIP file at the root of your device’s internal memory, reboot into recovery and flash the ZIP file (which will invoke the updater script in turn and enable the boot animation).
Step 4: Reboot the device. You should now see the new boot animation that you placed in system/media partition, as opposed to whatever you had earlier.
