Unable to install Denim update in Lumia 520

When i try to update my 520 to get denim update it says "The update was downloaded but couldn't be opened. (80070003). I did a factory reset two times and but did not get any luck. Any ideas?

This failure code is strange some people got it but it was when they downloaded music.
I would suggest to use Lumia software recover tool. See below link.
