click on settings tab in lower right hand corner, or shortcut on home screen if you made one.
on the left hand side you see a list of items, locate the last item listed, "ABOUT DEVICE"
click on that "ABOUT DEVICE" of course!
in the list to the right the first or second item listed is "SOFTWARE UPDATE", click on that.
(I found that even though I had AUTO UPDATE checked off it did not auto update nor would it check for and update unless first I unchecked that box).
So the short is, "UN-CHECK AUTO UPDATE" at least for now, you can re-check it later if you wish.
next click on the top item "UPDATE"
a message will occur asking you to select your country "UNITED STATES" for example.
the download will start
the update will be applied,
the total process of downloading the update and then applying it in the TAB took about 20 minutes, so just let it do its business until it is finished.
hope this helps
