Camera not launching after denim update-L720

[Gautham V kunnath]

I have updated my Lumia 720 with denim update and since then camera is not working.
When I launch the camera app, it says my phone doesn't have a camera!!
Strange!
How do I downgrade my phone now?
Both my primary and secondary camera stopped working after update and I even tried doing hard reset, still it dint work out!
I have tried using Nokia recovery software to downgrade, it says downgrade to denim available, when I'm already on denim!!
Plz help!!!

Reinstall Denim using Lumia Recovery. It should be a problem with the files you downloaded

I have tried this process too..
It shows available version to downgrade as denim!!
Basically I want to downgrade to cyan!!
I have not updated any of the early release software (dev preview) on this 720.
It had Cyan earlier
I want back cyan...

I have the same issue with mine. Have tried reinstalling software via recovery tool and hard resets. Some bright spark will be by shortly to say it must be a hardware issue and take it into a care centre. It isn't though, its too coincidental. Googling reveals we are not the only ones.
