Install Stable Android L on LG Optimus G E975

LG-Optimus-G-Android-L

Android L is still in testing phase but that doesn’t mean that you can’t already use it on your Android device. Of course I am talking about installing compatible custom ROMs that can bring a preview version of the Android L platform ahead of its official roll out, right on your Android smartphone or tablet. For now we have ported firmware for several Nexus devices and for the HTC One M7, while recently the LG Optimus G also received the Android L treatment.

Until now there wasn’t a stable firmware based on Android L available for the Optimus G, so we couldn’t bring a proper guide for you. But now, thanks to those of xda-developers you can safely install a ported version of Android L on your LG Optimus G as a stable and smooth variant of the software has been released for your smartphone. Therefore, in case you want to take a look over what’s new in the highly expected Android major update, don’t hesitate and apply the guidelines from below – the update operation will be similar with what you apply for any other custom ROM based on Android OS so you have nothing to worry about.

This Android L OS can be safely installed for a daily use as almost all its features are perfectly working for the LG Optimus G. Those who have already flashed Android L on Optimus G reported minor issues with the following: the camera is a little bit buggy, NFC isn’t working at all and there are some heat issues. All the other apps and features are working without any problems and the Android L will smoothly run on your Optimus G E975 – the firmware runs without lags or force close errors and there aren’t any boot loop or screen freeze issues reported.

Of course this is not an official update released by Google for your smartphone; you are facing with a custom ROM developed by third party devs that is only based on Android L firmware. Therefore, this guide is unveiling an unofficial update operation that will void the warranty of your LG Optimus G. Unfortunately, you can’t install Android L on your phone without losing the warranty so if you think that you can brick your device while applying the guidelines from below, maybe the best will be to stop right here. Anyway, if you stick to the info that is described here your handset will be in safe hands.

But for being able to flash Android L, first you will have to root your LG Optimus G. By gaining root access you will remove the factory and default restrictions from your device and you will ensure that the custom ROM will have permission to access in built features and programs. So, gaining root access is a must in our case; moreover, a must is also a custom recovery image. In that matter you should flash the latest version of CWM or TWRP recovery on your phone – the custom recovery will link the internal system of your device with its UI, thus you will be able to flash the .zip file with ease and without using other custom or complex tools.

At the same time it is more than recommended to backup your data before doing anything else since all that’s saved on the internal storage memory of your phone will be erased during the update operation. Thus, take your time and use backup and restore tools for saving what you might need afterwards, including contacts list, call logs, market apps, internet settings and personal data, info and accounts. Since Android L is still on testing phase the best will be to make a Nandroid backup for saving your current ROM – you will be able to easily restore the same if Android L will be buggy or if you will not like the new Android firmware on your LG Optimus G.

Now just ensure that you can use a computer as on the same you will have to download some files – in order to safely perform the download operation, first deactivate (only temporarily) the security protection that runs on your computer. A connection between your devices will have to be established, so your phone’s USB cable must be near you. It is important to charge your device especially if its battery level shows less than 50% power left (your smartphone might get bricked if it gets turned off). From “menu – settings – developer options” you should check the USB debugging option on your phone or else you might not be able to properly connect it with your computer.

Android L update file which is provided during the following steps is compatible only with the LG Optimus G model number E975; don’t apply this guide if you have a similar or different Android device as you can end up in damaging its internal system.
