These are the steps to update the Google Nexus 10 to the Android 5.1.1 Lollipop factory image. The factory image comes with the build number LMY48M for the firmware version. A factory image is the installation you want if you plan to return the Nexus 10 back to stock firmware. Installing a factory image is useful for people who want to get rid of a custom ROM, custom firmware or any custom builds. Most commonly, that is due to builds from the Android Open Source Project.
