build 10536

The Windows 10 Mobile Build 10536.1004 is out for Insiders in Fast Ring and you can read the official changelog here. Now the build has a lengthy and bit tricky installation process, which we are now experiencing first hand. You need to install Build 10514 and Build 10536.1000 before installing Build 10536.1004. If this sounds too lengthy and time taking, then you are right. Else you can use WPRT to go back to Windows Phone 8.1 and then update to Build 10536.1004 in one go, which is still tricky. (

In a nutshell here are the installation options,

Users on 8.1:

– You will jump directly to the new build.  8.1 -> 10.0.10536.1004

Users on Win10 Build 10536.1003:

– A very small group of users received the .1003 build we didn’t officially release last Friday.  This build was pulled back because of an update bug that prevents users from installing newer builds.  If you are on this build and your device scans for the .1004 build, you will see error 8018830f on your device.  Unfortunately, you will need to use the Windows Phone Recovery Tool (WPRT)) and flash back to 8.1.

Users on Win10 Build 10512:

– You will see two hops to get to build 10.0.10536.1004.

First update screen will show two interim builds coming down (10514 and 10536.1000).

Once that portion of the install completes, you’ll get a second install showing build 10536.1004.  This is the “landing” build and when this portion of the install is finished, you’ll be on the newest build.

There are some known issues with Build 10536.1004 that you may like to know before upgrading.

Build 10536.1004 known issues:

  • After rebooting your phone, you won’t see notifications, such as new messages, until you unlock your phone. After that, you should see notifications for new messages just fine.
  • “zStorage” appears in the Settings app under System and clicking on it causes the Settings app to crash.
  • Camera upload to OneDrive may not be enabled based on prior settings. To fix this, make sure you are running the latest version of OneDrive by opening the top left navigation bar, then settings on the right to verify that camera upload is turned on and you have the latest app (version 17.2).
  • Insiders will not be able to move from Slow to Fast rings temporarily; we are working on a fix but in the interim to move a device from Slow to Fast you will need to use the Windows Phone Recovery Tool to first start on Windows Phone 8.1 and opt directly into the Fast ring.
  • Additional languages for speech and keyboards won’t be available until tomorrow (9/15) and will error if you try to download. If you already have languages for speech and keyboards downloaded to your phone prior to upgrading, they will remain and available to use.
