LG Optimus L9 is an appreciated mid range Android smartphone that comes with Android Jelly Bean OS pre-installed. Now, the L9 will receive Android 4.4.2 KitKat OTA update soon, but if you want to spice things up a little bit, you can choose to skip this update, or to use something else until the mentioned OTA will be officially rolled out by LG. In that matter I recommend you to update your LG Optimus L9 with CM11 Custom ROM firmware. Therefore, if you want to install this Android 4.4.2 KitKat based software on your device, don’t hesitate and use the guidelines from below.

CM11 is one of the most popular custom ROM that can be installed on the Android system, so flashing this Android 4.4.2 update on your LG Optimus L9 is a must have especially if you are an advanced Android user who wants to obtain more power from its Android smartphone. In that matter you should know that CM11 is coming with great features, apps and capabilities that will optimize the performances and customize the looks and the Android system.

Of course, CM11 is bringing the Android 4.4.2 KitKat OS to your LG Optimus L9, which means that you will be able to enjoy the latest Android OS without waiting for the official OTA to be released. Moreover, with CM11 installed you will be able to remove bloatware from your phone, to speed it up, to improve the battery performance and to customize it by your own taste. Your device will become your new playground.

Since we are talking about a custom ROM, it should be clear for you that CM11 represents and unofficial update that is only based on stock Android 4.4.2 KitKat system. Thus this installation procedure is also unofficial, so by completing the guidelines from below you will void the Optimus L9 warranty. Also, for being able to apply CM11 on your Android smartphone, first you will have to root it. Gaining root access is also a risky operation, so use a compatible and tested tutorial when trying to unlock your Android device.

After gaining root access you need to install the latest version of CWM or TWRP recovery on your LG Optimus L9 because the CM11 custom ROM can be flashed only by using the mentioned tool. Now, as I have already pointed out, the warranty of your device will get void; don’t worry though as you can anytime choose to restore the warranty by downgrading your L9 to stock / official Android OS – a manual update operation will be required because on a rooted handset you can’t receive or flash OTA releases.

On the same time in order to succeed with this update procedure, first you have to prepare some things. In that matter you should ensure that a computer can be used and that your phone’s USB cable is near you. Now, on your computer disable the antivirus and security protection and on your smartphone enable USB debugging option by going to “menu – settings – developer options”. Furthermore, charge your L9 before installing CM11 custom ROM as if you phone gets turned off in the middle of the update operation, it might also get bricked out.

A backup is highly recommended because on the update operation a wipe will be required; thus you will lose all of your personal data, info and accounts along with internet settings, market apps and everything else from the internal storage memory of your phone. So, don’t hesitate and use compatible backup and restore apps from Google Play in order to save your data before going any further.

Finally remember that this is a dedicated step by step guide; that means you can’t use the steps from this tutorial for updating with Android 4.4.2 KitKat CM11 a different or similar Android device with the LG Optimus L9. So, be careful in what you do and try not to mess things up – just stick to the guidelines from below.
