The affected models are the Lumia 520, 525 and 526, which is a shame given that the phones are some of the most popular Windows devices Microsoft/Nokia has launched to date.
"We are seeing some reports of failures on Lumia 520/525/526 devices when trying to roll back to Windows Phone 8.1 using the Windows Phone Recovery Tool. We are pausing build availability for these devices temporarily while we investigate the issue and work with customers who have reported problems," said Microsoft.
The build in question is 10051, released last week to the Windows Insider program for 'Fast Lane' users who are willing to work with buggier operating systems get quicker updates.
Microsoft should be quickly working on a fix for the build which is an important milestone for Windows 10 thanks to the addition of the Project Spartan browser.
