Recently after reading about the new Windows 8.1 Update, I couldn't wait for it to be released and so I downloaded the preview for developers app etc. in order to install it early. For several months it has been working absolutely fine until recently I tried to update the phone and after taking a while to install I got the message:
'this update was downloaded, but couldn't be opened. (8007000d)
I've reset my phone but the problem is still happening. I am really keen to update the phone as I now know Cortana is available in UK for developers. What should I do?
Thanks in advance for any help!
