Error when updating from android 5.0 to 5.0.1

I got error message when i update my nexus 5 to 5.0.1, my nexus downloading the update and restart, after that in the middle of the process, it suddenly says error

Probably it have something to do with i root my nexus 5, so how do i fix this?

I'm using Nexus Toolkit to root so can i use the Toolkit to unroot without losing data?
after that will i be able to update OTA?


Thanks


Update: I use Toolkit to Flash stock + unroot and it worked and i didn't lose any data (Must go to option and check unwipe data). I first unroot using supersu but that didn't work, just want to share it

It definitely has to do with root. Since you can do things when rooted that would cause the update to brick the phone, a phone that shows signs of being rooted, or having been rooted, won't update. The update process checks for that, and the stock ROM, before it does an actual update, and fails if it finds either rooting or a different ROM.

If you're running SuperSU, go to settings in the app and you can completely unroot and have root survive. I don't know if Superuser has the same ability, since I use SuperSU.
