Try using towel root, look it up on Google very easy one click no reboot method. I have NE1 and rooted using this method.
Go to the website, click on the image and it'll download the towelroot apk, make sure you have the install from unknown sources checked in developers options. Install the towelroot then use an app like root checker to see if it rooted successfully. Also for better results use the stock browser instead of Firefox or anything, some of them won't download the file but instead open it as text.
