Windows 10 Mobile Build 10586.11 is here now, available for Windows Insiders in Fast Ring. Now, while a reboot loop issue had delayed its flight seems there is still a reboot loop issue if you upgrade from Build 10581 and you have done a hard reset while being on Build 10581.
If you have done a hard reset while on Build 10581, better use Windows Device Recovery Tool to roll back to Windows Phone 8.1 and then upgrade directly to Build 10586.11. You can read our recovery tutorial for step by step roll-back instructions. In case you have already upgraded and stuck into reboot loop, you can use our reset tutorial for recovering your phone using hardware keys.
Build 10586.11 Known issues:
- 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.
