What kind of down grade did you do from cyan + dfp to cyan.
Did you get an error during down grade.
Did you disconnect your phone during the down grade processes.
Did you try the option "my phone is not responding"
Is it possible that your battery is flat?

Use Lumia Recovery Tool. Your device might not be showing in computer, Use dead phone flash in lumia recovery tool.
Remember connect only one device to your computer.

You said battery is no problem in your above post.
If you are not sure put it on a charger or even better ask someone with a 520 if you can borrow the battery.

Sorry I don't know any other recovery tool/

There is an other way. You have to do a full flash of a new rom. Therefore you need the productnumber of your phone and download and flash the rom manualy

The tools can be downloaded from here.
