Android is the greatest ecosystem for mobile devices but among things of “WOW” there is a great disparity of distribution that is certainly not a good thing. Android is the only OS with multiple OEMs who theme and customize it with their own flavor. This variety is probably the greatest reason behind the time-gap between the pure AOSP updates released by Google in Nexus devices and the customized updates for device from other brands. It has been more than four months since the time Android 4.4 KitKat was released but the new flavor of Android made its way to device from OEMs like HTC, Samsung, Sony and LG after months. As a flagship phone, the KitKat update turned its face to the LG G2 rather late. Anyway, the Android 4.4.2 update is finally out for the device. Following the Open LG G2 and AT&T G2, the T-Mobile variant started receiving the official KitKat. If you own the awesome G2 and have rooted and install TWRP/CWM recovery on it, you’ll not be able to receive and install the OTA. For users with a custom recovery, downloading the KitKat firmware using LG Mobile Support Tool and installing it manually might be the only way to get the new update working on their device. However, flashing the official firmware with .kdz or .tot extension will remove the root and custom recovery both. The bad news is that there is no working method to root the LG G2 on the Android 4.4.2 KitKat firmware. And, the good news is that, if you own any of the following models of LG G2 with root and TWRP/CWM recovery, there is still a way to preserve root on the device.
- AT&T G2 D800
- T-Mobile G2 D801
- Open LG G2 D802
- LG G2 D800/D801/D802
- Root access and TWRP Recovery version 184.108.40.206 or higher.
Note:If your LG G2 does not have root access and a custom recovery, you can install the Android 4.2.2 KitKat firmware manually by following this tutorial.
