Nexus 4 users who have already updated their device to Android 4.3 Jelly Bean and currently looking for a root may follow our step-by-step guide. The tutorial uses CF-Auto-Root file by recognise XDA developer Chainfire. The CF-Auto-Root, as claimed by the developer, is meant to be used in combination with stock firmwares and is the quickest and safest way for first root. Besides, the root package contains SuperSU binary and APK. The root package supports Android 4.3 and future firmwares as well. Head over to the development thread to learn more about the root release.

IBTimes UK reminds its readers that it will not be held responsible for any damage to the device. Users are also advised to verify that their devices meet following requirements.

Pre-requisites

1) Install USB Driver for Nexus 4 to transfer files between the Android device and the computer.

2) Enable USB Debugging Mode on the phone to connect the Android device with the computer and use the Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option and then check the USB Debugging Mode.]

3) As the tutorial might wipe out all data of the phone, create a backup. If the device is having any custom recoveries such as CWM/TWRP already installed then back up data using the recovery.

4) The Nexus 4 should have above 80% battery charge.

5) The phone should be factory unlocked and not locked to a particular carrier.

6) The CF-Auto-Root file is compatible only with Nexus 4. As applying this to any incorrect variant is likely to brick the device, verify the model number of the Nexus device by navigating to Settings>> About phone>> Model number.

7) Rooting the device will void it of its manufacturer's warranty. Users can reclaim the warranty back by unrooting it later.

Note: If the device has not been unlocked before, then this procedure is likely to wipe out all data.
