Lava stopped rolling out any further update after Android 4.4 Kitkat for Lava Iris 504Q. Now, as we are in era of all new Android 5.0 Lollipop with several new features, new animations and new UI called Material Design. Can Iris 504Q users get the taste of Lollipop? Yes, of course. Here is the Lollipop 5.0 based Custom ROM for Lava Iris 504Q.
It is very light ROM, consuming just about 300 MB of your system, that is even less than the original factory rom. Performance is smooth and you get new look of the device. You can check the Performance in this video. Installation consists of three steps, i.e Rooting, Custom Recovery, and ROM installation. You can check the step by step installation guide here having the video tutorial as well. In this post, i am attaching all required files for this process. Have Fun !
