Settings -> Language, make sure English (US) is at the top of the list. Press and hold to move it up. Restart.
Then wait for it to be downloaded/updated (if necessary).
Still not getting Cortana.
Keyboard is English (United States)
Language is English (United States
Region is United States (English)
and Speech is English (United States)
Any other settings I'm missing?
Hard reset your phone.
Change region to USA.
Change language to USA English.
Go to phone updates.
Wait till it downloads an update to update your language.
It will restart the phone, install update.
Once you are back up, Cortana will be installed as an app.
I just did this, made a hard reset, did all the settings you provided and cortana still disnt appear on my htc 8x
