I need to update my Lumia 520 from Windows Phone 8.0 to 8.1, but it is not allowing me to download it over the mobile data and I don't have any wifi access.

Is there any way to manually override this so I can download the update on mobile data?

  • What firmware version are you running? Check Settings > Extras+Info and see what it reports as "Software release". If I recall correctly, the ability to download OS updates over a cellular connection was added in GDR3 (Lumia Black), so if you have an earlier version, Wi-Fi might be your only option. – Indrek May 13 '14 at 12:28
