So today i enrolled in the insider program for phones to try out the build 10166 as I've seen in reviews that it is now stable enough to be used as daily driver.

I am currently on official Lumia Denim aka WP 8.1 Update 1

I enrolled as Fast Ring insider and the phone restarted. After that got an update notification for build 10166. So I started the download. Took a whole lot of time to reach around 60% then it reported that it could not install the update.

Tried around 3-4 times but did the same.

At a point it reached 83% but again failed. Eventually ended up clearing some of phone memory to around 3.55 GB and now it is downloading again.

Any reason as to why this might be happening??? I'm eager to try out this build. Any help is much appreciated.
