Cyan update not downloading although it's available...
You have a WP device. You installed WP 8.1 via the developer preview app.Now that
the official Cyan update is available for your model as confirmed by Nokia and/or your network, it still doesn't show up...
What to do?
Some sources suggest you restore to WP8 via Nokia's recovery tool.
But oops, people still don't get the available update after they have done that.
So, what to do?
Microsoft/Nokia are aware of the issue. It IS not intentional.
It's a flaw/bug, and they are working on a solution...
Meanwhile, using the recovery tool may actually make things worse.
And hey: GDR1 is around the corner, so you may as well wait for that...
