How to update Lumia 930 to Windows Phone 8.1 Update

Step-1: The Lumia 930 will notify users when the new update is available. You can manually check for the update from Settings>> Phone Update

Note: Users are advised to use Wi-Fi network to download the update and thereby avoid mobile data transmission cost. Also, before installing the update, ensure that the handset has above 80% battery charge. Ensure that the device has enough space for the update -- at least 1.5GB free phone memory. To check the available free space navigate to Settings>> Storage check (storage sense).

Step-2: To view and install the update, tap the notification message, and follow the on-screen instructions. You may opt to install the update immediately or postpone the update to a more convenient time.

Step-3: The update should take about 15-20 minutes, but in case of major updates it could take up to two hours. You are not allowed to use the phone during the update. Follow the on-screen prompts and do not worry if the phone restarts several times during the installation process.

The Lumia 930 should now be running Windows Phone 8.1 Update 1 build 8.10.14157.200.
