Microsoft has just pushed out a new build of Windows 10 Mobile to Windows Insiders today, coming in at build number 10586. The new build brings a number of bug fixes to the table, but of course, there are some known issues lingering around. Here's the breakdown of the known issues in the latest build.
- After we released Build 10581 to Windows Insiders in the Fast ring, we discovered a bug in the build that will cause the filesystem to become partially corrupted after doing a factory reset. For those of you who did a factory reset of your phone, you most likely did not notice this issue on Build 10581. Due to this bug however, upgrading to Build 10586 will cause your phone to go into a reboot loop after the upgrade completes – rebooting at the Windows or operator logo. To recover your phone, you can use the hardware key combination to reset your phone which will then put it at the OOBE experience on Build 10586. We highly recommend that you make sure you do a backup your phone before upgrading to Build 10586 due to this bug. Additionally, you can also recover your phone by using the Windows Device Recovery Tool to go back to Windows Phone 8.1 and then upgrade to Build 10586.
- Deploying Silverlight apps through Visual Studio to your phone still won't work in this build. This issue will be fixed with the release of Visual Studio 2015 Update 1 on Nov. 30th. You can deploy UWP apps to your phone without any issues.
- There is a known issue where the tile for Insider Hub still remains under All apps but doesn't open. Insider Hub isn't included in this build. There isn't a way to get it back unfortunately. However, it'll return in a future flight! In the meantime, use Insider Hub on the PC as a workaround.
And there you have it. As noted, make sure to do a backup of your phone before upgrading to the latest build in case you run into the reboot loop issue.
