Not able to root after re install of OS?

So I had to re-install my firmware/ Operating system through odin because i accidentally deleted it. it worked, and i have my phone back again, but it seems im not able to root it again, I have tried rooting it again through kingo root and it gets stuck at waiting for device and then it says it failed. Then I tried through odin and it just resets my phone. this is the changelog from odin
