Re: Can we revert back or Download 4.4.4 again?
I believe that you can; it involves reflashing the factory image. A factory reset will not work because it simply erases all user data and reverts to a "clean" install of the current firmware. I'm moving this thread to the S5 section to get more specialized help from people with that device. I can walk you through how to do it on a Nexus but I haven't owned a Samsung in quite a long time.
