I have the factory image. but I don't know how to reflash(?) it.

I'm using rooted nexus 4(the original ver. 4.3). Actually I don't remember how I rooted it. Several errors occurred during it rooted(It didn't boot also at that time). Anyway, I have a problem with battery issue after rooting(Android OS is always 30~40% usage). So I want to know how to go back...
