Update AT&T LG G2 to Android 4.4.2 KitKat without Losing Root

The AT&T LG G2 D800 has been receiving the Android 4.4.2 KitKat update via OTA for quite some time now. Many users have already received the OTA but their are still many who could not update their AT&T LG G2 because they have rooted their device. Then, there is another sect of people who want to take the KitKat update but they won’t update their phone because they are afraid of losing root access and custom recovery.

Just about a week ago we came up with a guide to update the AT&T LG G2 to Android 4.4.2 KitKat without losing root. Today, we have come up with another tutorial for the users of the phone. XDA member garyd9 has compiled a ROM for the AT&T LG G2 D800 that is based on the D80020c KitKat build.

Since the latest bootloader that comes with Android 4.4.2 update does not allow replace itself with a custom recovery, garyd9 made an intelligent move so that you can install CWM or TWRP recovery on your AT&T LG G2. He removed the new bootloader from his ROM so that when you install his KitKat ROM, your device still remains on the old D80010d bootloader that allows a custom recovery.
