I deleted saved picture album by mistake from my Lumia 820. Can I return it back with Zune app or something other ways? Btw I didn't activate the OneDrive service before deleting the album.
If you didn't back up your photos in any way (through Zune or OneDrive for example) there is not really a way to recover those without opening up the device, getting the memory chip, rendering your warranty void and propably damaging the phone. Sorry.
