I have been trying to make Cortana work on my Lumia 520. I have followed the guidelines provided by Microsoft:
- I have updated the phone to Windows Phone 8.1
- Language is set to English (India)
- Region is set to India and regional format is "match phone language"
- Finally, speech is set to English (United Kingdom)
I restarted the phone but when I press the search button for a while, it still opens the old Bing app. If I search "Cortana Settings", the Cortana settings page appears, but Cortana is off and I cannot turn it on. It says "Not available in this region".
