How to install Windows 10 Technical Preview on AT&T Lumia 920?

[Windows Central Question]

The basic requirement to get Windows 10 preview is Lumia Denim. However, as everyone is aware AT&T has not released Denim update to 920 model (and may not even release it in the future). In such case, is there any way of installing Windows 10 preview on Lumia 920?

I believe that AT&T is not releasing the second Denim update for the 920. I may be wrong.

Have you tried downloading the Windows Insider app from the store and activating it for the Fast updates. Give this a try. think you already have Denim first release and if so, this should allow you to upgrade to the latest WP 10 release.
