Restoring original volumes in service menu

I have been receiving emails from people who have entered their service menu and changed some values. Some have changed values by mistake and others just want the original values. I have uploaded the 4 files that contain the ear,spk,rcv, and bluetooth original values. These four files can be used in 2 ways. The first is for reference in case you messed up and want to know what the original values were or they can be re-written using TKFileExplorer over the original ones in  your phone to restore volume settings back to the way it was originally.

They are located in the phone at SystemFS\Drivers. These are the original unchanged files.
