KingRoot lets you root Nexus 4 (and many other phones) in no time

There are situations when you need to root* your phone in order to install for example MultiROM Manager etc. These are the steps I took with my Nexus 4:

• In Settings/About tap Build Number seven times to enable Developer mode.
• Allow Debugging in Developer settings.
• Allow External Sources in Security settings.
• Download KingRoot root tool apk-package from http://www.kingroot.net/ .
• Install KingRoot apk, fire up KingRoot, follow on-screen instructions to root your phone.
• Your phone is rooted!
