LG Optimus L5 E610/612 Android 4.1.2: How to Root and Install Custom Recovery

Updated with Video Guide. It is indeed a bad news to LG Optimus L5 users as we are hardly seen continuous development on this device. Android 4.1.2 Jelly Bean firmware has been released on Optimus L5 for quite a long period but yet we fail to find some workable rooting method from 3rd party development platform. We have been trying on every single root tool in the web such as unlock root, Framaroot, one click root etc but none of these root tools gain access to the latest Android version on Optimus L5.

Nevertheless, dev-DaT Senior member of XDA forums throws some light on Optimus L5 development where he manage to root Optimus L5 on the latest Android 4.1.2 Jelly Bean stock firmware. This is rather easier than rooting Optimus L5 running Ice Cream Sandwich (ICS) as you only need to flash a pre-rooted firmware with KDZ updater. In the same time, ClockWorkMod recovery will be installed along with the installation of the pre-rooted firmware package. This root method is applicable to LG Optimus L5 E610 & E612. After flashing this root package, your device will now recognized as E610.

LG Optimus L5 E615 is officially unveiled in September 2012 and it is the mid range smartphone in LG Optimus series. LG Optimus L5 is equipped with 800MHz dual core Qualcomm Snapdragon processor and 512MB RAM, 4GB internal storage with expandable microSD card slot up to 32GB. It comes with Android 4.0.3 Ice Cream Sandwich firmware.
