6. Train Cortana

Once the phone has restarted with the correct English (United States) language you can go back to Settings > Extras > Hey Cortana and begin to train Cortana again to use your voice when the display is off.

if you are a UK users and cannot use Hey Cortana even though you have the feature, you will need to reverse Steps 2 and 3.

We did confirm this worked on our Lumia 1520, so it should work on your phone as well.
