The latest Android 4.4.3 KitKat software update with build number KTU84L is now rolling out for Google's Nexus 7 2013 model (Wi-Fi variant). A similar update for the LTE variant should be coming soon. Along with performance improvements, the update brings several bug fixes for the Nexus tablet.
Those who have already installed Android 4.4.3 KTU84L KitKat on their Nexus 7 2013 and are currently looking for a root method may follow the step-by-step guide below.
The method below uses SuperSU package for rooting the tablet. Besides, it explains how to install the latest version of custom recovery. There are two custom recoveries; CWM and TWRP. Users may flash either of the recoveries.
IBTimes UK reminds its readers that it will not be held responsible for any damage to the device. Users are also advised to verify their devices meet the following requirements.
- Install USB Driver for Nexus 7 to transfer files between the Android device and the computer.
- As the tutorial might wipe all data of the tablet, create a backup. If the device has any custom recoveries such as CWM/TWRP installed then back up data using the recovery.
- If the Android device powers off due to lack of battery during the process, it could damage the device. Therefore, the Nexus 7 should have above 80% battery charge.
- The SuperSU root file and the custom recoveries used in the tutorial are compatible with Nexus 7 Wi-Fi 2013. As applying these on any incorrect variant is likely to brick the device, verify the model number of Nexus 7 by navigating to Settings>> About tablet>> Model number.
- The tablet should be on Android 4.4.3 KTU84L stock firmware.
- Rooting the device will void manufacturer's warranty. Users can reclaim the warranty back by unrooting it later.
