Aren’t you completely satisfied with the existing Android that runs on your International LG G2 D802? Then, there is an alternative available for your device which I think that you’ll like: I am talking about the CM 12 Android 5.0.2 Final ROM which comes with improved stability, major security fixes and not only.

You can use this tutorial only for the International LG G2 device model number D802, so before taking any other step, you must check the model number under Settings> About Phone; else the CM12 Lollipop firmware can’t be used for your smartphone.

I want to warn you that you cannot update any other devices with the files that you will find in this post or your risk damaging it. You must also root your LG G2 and you have to install the latest TWRP or CWM Recovery on your device in order to support the CM 12 Android 5.0.2 custom ROM flashing process (the choice is all yours).

Do not forget to create a complete Nandroid backup along with a complete general backup of your data as the update will erase it all and enable the USB Debugging option on your handset – to do that, you have to follow Settings>Developer Options>USB Debugging. You must also charge your device in order to make sure that it will not shut down during the update and prepare the original USB cord.

Have you installed the phone’s USB drivers on the PC? If not, it will not be recognized by the computer, so take care of this aspect now and do not forget to deactivate the antivirus which might stand in the way of this operation.

Last but not the least, understand that I will not be responsible if you damage or brick your LG G2 while updating with CM 12 Android 5.0.2 Lollipop OS. Do it at your own risk only, follow the instructions properly and be prepared to accept the consequences of your actions. Are you willing to take the risk yourself?

Also remember that the operation is not only risky, but it’s known that the warranty of your LG G2 will be voided and so it will cost you to repair your handset (learn How to Restore the Warranty on your Android device).
