Microsoft added it had to pause the build 10051 availability for Lumia 520 as a small number of devices experienced issues while trying to roll back to Windows Phone 8.1 through the Windows phone reset tool.

The company said: "We are seeing some reports of failures on Lumia 520 devices when trying to roll back to Windows Phone 8.1 using the windows phone reset tool. We are pausing build availability for these devices temporarily while we investigate the issue and work with customers who have reported problems."

An update has been released to Windows Phone Reset Tool that should get the issue resolved.
