Welcome to Android Central! If there's an official Samsung firmware here, then you could flash it using Odin: http://forums.androidcentral.com/am...w-flash-stock-rom-via-odin-new-interface.html. Otherwise, you'll have to research how to root the phone and find a custom 4.4.4 ROM specific for your device.
