Can't update W10M from build 10166 to 10512.

Hi,
why on my Lumia 920 can't update Windows 10 Mobile Insider Preview from build 10166 to build 10512? When I open updates in setting I get message Your device is up to date. But in about I see that my OS version is 10.0.10166.0. I am using fast ring.

Have you tried running the insider app and choosing the fast ring again? This might be a simple suggestion but a lot of people forget to do that after doing a hard reset.

I did that but I couldnt update to the next build. I running insider app and choosing the fast ring after that the update was available but when I clicked on that my phone didnt update.
What should I do?
