    Default I cannot update to 4.4 signature verification failure

    Can someone please help me here.. I'm totally brand new to all this Android business I'm pretty generally good a tech but all this DROID terminology is boggling.. Basically I bought a s4 it's running on google and I have the update pop up to 4.4 but when I click install everything is fine for 1 minute until it then says are you sure you want to install from an untrusted source and then failure signature verification

    Can anyone please explain in a very layman terms what I need to do to update to 4.4 I don't really know what root and flashing and device and all that means, also I tried connecting to kies but it doesn't work even after trying the fix methods

    Thanks in advance
