Have no idea how to use kies to do that. Why does it not say your software is is up to date like it use too? I know its a stupid question so I will probaly get stupid answers. Im not as smart as some of u.
Sometimes, when an update is available for your device but not yet accessible in your region, you'll see errors like the one you encountered.
I could give you a write up, but there are plenty of videos on YouTube that will walk you step by step through the upgrade process via Kies. Now, if you have a problem installing Kies itself, come back and I'll run you through it.
