Anyone with a Verizon LG G2 has the unofficial KitKat 4.4.2 build coming out OTA. To install it will require some experience of custom ROMs, though.
You’ll need the VS98012B stock build and it’ll have to be flashed. Then you’ll need to root the phone using AutoPrime. It’s an easy process, but tedious.
Once you’ve rooted the G2 you’ll have to download the bin file and rename it. Then transfer it to the LG G2 folder and key in commands in ADB.
If you’ve done everything right your phone will reboot and treat you to KitKat! Don’t forget that this is just for Verizon handsets.
