How to update and upgrade Win10 Mobile 10572? Need to roll back to WP 8.1

  

Based on feedback from Windows Insiders users, Microsoft pushed Windows 10 Mobile Build 10572 to Fast Windows Insider members.

This new version includes some new features, fixes a lot of bugs, and improves battery life and performance. However, if you want to upgrade this version, you need to roll back to Windows Phone 8.1. Microsoft Gabe Aul said on Twitter today that there is no fix bug in build 10572, so it can't be upgraded from Win10 Mobile version (10166, 10536, 10549) to 10572. If you don't want to roll back WP8.1, you can wait for the next version of Windows 10 Mobile build 10575, which can be upgraded directly from the current Win10 Mobile versions 10166, 10536, 10549. Microsoft is expected to push the 10575 version next Tuesday.

Microsoft has finally accelerated the progress of the push, we also hope that the next version can get better and better, looking forward to the official version of Win10 Mobile.
