Samung Carrier splash & sound remove

First of all you will need to download the new boot animation file. If you want the original Samsung Boot Animation, download it here. Go to /system/media and save the files somewhere else just in case you want to revert back.
Download the BootAnimation zip file. Since it’s a zip file, extract it.
Copy the files from the folder to /system/media. Replace the old files.
The files you have to copy are named like this:
bootsamsung.qmg
bootsamsungloop.qmg
shutdown.qmgFrom the BootAnimation zip file copy these files:
PowerOn.ogg
PowerOff.ogg
Copy them to /system/media/audio/ui by replacing the original files. Make sure you backup the old files.
