Microsoft Releases Windows 10 Mobile 14977 with Possible Installation Errors – No Build for PC
Microsoft has released a new update to Windows 10 Mobile Insiders on the Fast ring. It's been a couple of weeks since the company released any preview build. PC Insiders won't be getting any new build this week, as the software maker said there is a "blocking bug that could result in broken apps after updating to a new build."
While PC users will have to wait longer, finally there is something for Windows 10 Mobile Insiders to be happy about. The new Windows 10 Mobile Preview build 14977 brings support for EPUB books in Microsoft Edge, along with the ability for third-party Alarm apps to break-through Quiet Hours. The rumored Reset App hasn't made the cut in today's release. Following are more details of today's Preview build.

Known issues with Windows 10 Mobile Preview 14977
There are a few known issues with today's build, including a possible installation error 0x800700b7 for Lumia 550. Here are the details (emphasis is ours).
- Please avoid attempting to install new languages, keyboards, and speech packs on your phone. There is a chance these downloads may get stuck and not finish downloading. If you have existing languages, keyboards, and speech packs installed – they will carry over when you update to new builds. You can use Windows Device Recovery Tool to go back to Windows Phone 8.1 or Windows 10 Mobile, install any languages, keyboards, and speech packs you need and then update to the latest build in the Fast ring as a workaround.
- Windows 10 phones with 8GB of internal storage such as the Lumia 550 will likely receive an 0x800700b7 error when attempting to update to this build.
- System related notification toasts (e.g. Bluetooth, USB/Autoplay, etc.) do not work.
