Where is my Cortana?

[zu5be]

I recently rolled back to Wp 8 for the cyan update and after all the hassle and trouble, Cortana is missing on my phone. Yes, i have kept my region to US. i am running 1520 with a UK rom.
Do you have any idea?

Cortana is only available in WP8.1. Unless you run 8.1 Preview or official 8.1, you will not have Cortana.
