Step 1. Go to the Samsung QMG section under AndroidBootAnimation.com and download the Android boot animation you want to install.
Step 2. Install and run Root Browser app on the Play Store.I use ES File Explorer app.But make sure you enable root and also enable R/W for system directory.Do a long-press on the boot animation zip file you downloaded. and Select “Extract” to extract the actual QMG boot animation files.
Step 3. We should now have a new folder with the QMG files.
Step 4. Before you can copy and paste the QMG files, you will need to delete the existing files so go ahead and browse to /system/media directory and delete bootsamsung.qmg, bootsamsungloop.qmg, and shutdown.qmg files.
Step 5. Go back to the new QMG files you extracted earlier and copy the files.And paste them in /system/media directory.
Step 6. Do a long-press on each of the QMG files and select “Permissions. Change the permissions to “RW/R/R”.
Step 7. Reboot Your Phone and See the New Animation.
