As the title conclude, we ALL Hong Kong Lumia 1520 users don't get the OTA update for Denim, and the official tracker has showed it's available for more than one week.
I could just speak for myself, but please read this forum thread, and you will learn that I'm not lying.
If you're convinced that there is such a problem, can you please check what's wrong in the configuration of your OTA update server?
If you want to tell me the OTA update process is controlled by Mobile Operator, I should remind you, the Hong Kong Lumia 1520 is a Country Variant model, it is not attached to any Mobile Operator. Or if you do insist there is a Mobile Operator for Hong Kong Lumia 1520, please name it to us. And then we can write complaint letter to protest against their OTA treatment.
And please don't tell me to use Lumia Software Recovery Tool, we don't need to loose our phone's data. What we need is OTA update.
Hopefully you can solve this annoying problem for All Hong Kong Lumia 1520 users, including me.
