Windows 10 Mobile Build 10549 released but you will need to roll back to 8.1 to install it

Microsoft have released build 10549 for Windows 10 Mobile for Windows Insiders, but installing it comes with a warning. Due to an upgrade bug Microsoft have made the build only install from Windows Phone 8.1 so you have going to have to roll back to Windows Phone 8.1 via the Windows Device Recovery Tool, install the Windows Insiders app and then do the install.

Steps from Microsoft:

Go back to Windows 8.1 first using the Windows Device Recovery Tool.

Once you’re on Windows Phone 8.1, install the Windows Insider app, choose the Fast ring, and reboot your phone.

After that – this build should download and install on your phone.

So what is new in this build? Well there is Cortana for Japan, Australia and Canada. The Messaging app has been improved with improved text entry and more emoji!

If you are a Lumia 1020 user, you may want to skip this release as Lumia Camera no longer works with Windows 10 Mobile so you will use many of the special camera features (it should be back later this year).

The issues with this release are:

•After upgrade, you might be missing a few apps. If you experience this, the workaround is to reset your phone.

•After rebooting your phone, you won’t see notifications, such as new messages, until you unlock your phone for the first time. After that, you should see notifications for new messages just fine. This bug is fixed in a later build.

•You will be unable to make calls with Skype for Business, WhatsApp and other apps after upgrading to this build. The workaround is to uninstall and reinstall these apps from the Store

You can read the full post on the Microsoft Blog and if you want to try the new build you better get the Windows Devices tool up and running.
