Might be picking up a rooted N4 that has a custom rom....

How easy is it to return it back to the stock rom? I don't necessarily want to un-root it, just want to put the stock rom on it..

Probably easiest and best to flash the factory images. All you have to do to regain root after that is flash a custom recovery and flash a supersu zip
