[Galaxy Tab 4 General] AndyPhreak:
I am also having nothing but trouble with Kies and the Samsung Mobile drivers, but I have a Windows 8.1 system with USB 3.0 ports and expect that might be part of the problem. I finally ended up installing AirDroid a few minutes ago to get the file onto my PC where I could fiddle with it.

As I suspected, Samsung haS given this update file an improper extension. After changing it from .zip to .tar I had no problems opening it with 7-Zip (though it did report a few minor errors). The tarball includes \system\CSCVersion.txt which contains a single string "T330NUXAR1ANK1", and \META-INF\com\google\android\updater-script which includes the following instructions (edited for brevity to meet the posting limit here):
