This question already has an answer here:

I have recently updated my Nexus from 4.3 to 4.4 . But having an immediate requirement i would like to downgrade back to 4.2 . I originally bought it with 4.2.

Any step by step to downgrade back are highly recommended. tried factory reset but of no luck. Is rooting mandatory for this? I have read some where that factory images are helpful. Please throw some light on this and a step by step document is needed being a layman on this?
