From the Manufacturer
The Lumia 520 ships with Windows Phone 8.0 and is now eligible for a free "Over the Air" (OTA) update to Windows Pone OS 8.1. For best results: Step 1. Your phone notifies you when an update is available for you. You can also check for updates, just tap Settings > Phone Update. Tip! Use a Wi-Fi network to download the update and avoid mobile data transmission costs. Before starting the update, connect to a charger or make sure your phone has enough battery power (at least 50%). You might also need to make enough space on your phone for the update (1.5GB free phone memory is recommended). To check for available free space, go to Settings > storage check (storage sense). Step 2. To view and to install the updates, tap the notification message, and follow the instructions shown on your phone. You can install the update immediately, or postpone the update to a more convenient time. Step 3. The update should take around 15-30 minutes, but a major update could take up to 2 hours to complete depending on your phone model. You are not able to use your phone during the update installation. Follow all the update prompts, and do not worry if your phone restarts several times during the process, that is completely normal. Additional app updates from the Store could be needed to fully enable new features for your phone. You will get the app update notification on the Store app shortly after the software update
