Why can't Lumia 710 update to 7.8?

[MariusIonut]

Hello. I have a Nokia Lumia bought by a friend from Spain. Zune tells me that there's an update for my phone, but whenever I try to update, it gives me error 80180048.
Is it about language pack? If I change to spanish, my phone isn't able to access Messages and the dial pad. Could someone tell my what is the problem and how can I update my software from 7.5 to 7.8?

P.S. Sorry for bad English.

Make sure your time and date are correct. I know that was a problem for my dads phone when I tried to update it. You cant update your phone if the date and time doesnt match Microsoft computers

Set automatically is on.
I have also tried a hard reset, but it doesn't work either.
Zune detects available update, I press "update now", phone restarts but doesn't complete the action, it starts up and tells me error 80180048.

Did you try looking up the error code?

Don't use automatic settings for time and date.. That always mucks up... Do it manually

I did, says it's about language packs, but I still don't get it. Tried to change the language on my phone to its original, spanish, but it doesn't work and can't even access the Messages or dial-pad. Guess I'll just leave it this way.

Tried that before, Zune tells me that the software is already up to date. Only in automatic settings shows me the available update.
