One of the best operating systems to come out on Android has been KitKat 4.4.2 and the majority of phone makers have sent out the update for handsets.
Now it is looking as though Verizon and the LG G2 could get more as owners of the G2 can get KitKat OTA. However is an unofficial build and you will have to know something about ADB.
So to start you do have to get hold of the flash stock build with number VS98012B. Your handset will need to be rooted with AutoPrime too. When you have done this you should download the bin file and rename this and then put it in a folder on your device. You then need to type in the ADB commands.
If you do everything right your LG G2 will reboot and you will have KitKat 4.4.2 installed. If you have experience in rooting your handset this will not give you any issues.
