Based on Android 6.0 Marshmallow, CyanogenMod 13 is finally available for quite a few devices and as you can see, your AT&T LG G2 is one of them as well. CM13 is an AOSP based ROM and brings near stock UI, Android 6 features, as well as CyanogenMod’s own features to your device, so I bet that you want to give it a try as well.

If you have been waiting to enjoy the latest of the team CM for a long time, here is how you can flash it on your AT&T LG G2, but note from the start that the currently CM13 is a Nightly build, so you might experience some instability, lags and bugs. Are you ok with that? Then, as always, root access and latest version of custom recovery (preferably TWRP or CWM) are both required to flash custom ROMs like CM13 on your device.

Then, you must also understand that the process will wipe off all the data stored on your LG G2. Therefore, before proceeding any further, please backup all your important data. And besides wiping your data, this process will also void your device’s warranty, but here you can find a guide that might help you with that: How to Restore the Warranty on your Android device.

Let me remind you that I won’t be liable for any damage to your AT&T LG G2 whatsoever. I won’t be held responsible if you brick your device or if something else bad happens to it while youflash the Android 6.0 CM 13 Marshmallow software, but it’s only your responsibility to assume. And even if you feel confident, it’s better to check the version of your phone and make sure that it is the d800 one. A mistake like this one could cost you more than you are imagining!
