Before rooting, make a backup of your device data such as SMS, internet setting, contacts music files etc because the below procedure may wipe data, you can sync your contacts with Gmail account and for messages use SMS apps, lastly use file expert app to backup apps. USB drivers must be installed on your computer, you can download drivers from here, unzip the downloaded drivers file and install them. Disable all system tools such as antivirus, firewall program. On your Optimus 4X HD, turn the USB Debugging on, to do so just tap Menu> Settings> Application> Development. You also need to enable Unknown sources, you can enable it from Settings>Security.
DISCLAIMER: Please proceed the below guide at your own risk, Android Egis will not be held responsible if your device lost data or get damaged following this guide.

Step #2: Unzip the downloaded onxr.zip into a folder on computer.
