The best-selling Windows Phone ever has Windows 10 preview pulled

Microsoft has been forced to temporarily cancel the Windows 10 preview for the world's most-popular Windows Phone, the Nokia Lumia 520. It follows reports from many users that their devices were bricked when trying to return to Windows Phone 8.1.

It isn't just the Lumia 520 that is affected. All of the phones in the 52x range including the 520, 525 and 526 are no longer eligible for downloading the recent Windows 10 preview release, build 10051.
This early build was only released last week after much anticipation. Many users have been waiting eagerly to run Windows 10 on their Lumia as the original build from a couple of months ago only supported a handful of devices.

The 520 is one such Lumia. Although one of the cheapest devices ever to launch in the Windows Phone world, this affordability has proven to be its greatest trait. It has attracted buyers young and old, including first-time smartphone owners, and brought in new people to the platform.
Popular in Asia and often owned by people "as a spare," Microsoft owes a lot to the 520 for actually selling in large numbers unlike its much costlier flagship devices such as the Lumia 930 or 1520.
