my nokia lumia got down graded I want denim back?

When my phone told me there was a upgrade available I pushed upgrade but 15 minutes later it had backgraded me from Lumia denim to lumia black! How do I get denim back?

The cyan update would be the first step, then just wait for the denim update or flash the phone (ROM), but be careful with this process.

Did you try soft -and then hard resetting the phone to check if it isn't just a glitch?
