If you have LG Optimus 3D P920, then you are at the right place as it might be known to you that LG has not planned any ICS or Jellybean Update for Optimus 3D. This custom ROM will enable you to use Android Ice Cream Sandwich on your Optimus 3D with all the features working fine.

This Upgrade will not only enhance the features of your Android Phone, but also increase the battery backup of your LG Optimus 3D.

Important Note: This Firmware is taken from a very reliable developer from XDA Forum and is completely safe to install on your device.Yet we would adive you to go for this upgrade at your own risk as neither this site nor the author can be held responsible for any problem in upgradation such as bricking of Device. However, this happens only in rare cases.Also you would lose warranty of the hardware(if any) after upgrade.

To make it easier for layman users, the entire upgradation process has been divided into two easy to understand parts:

  • Pre-Upgardation Steps.
  • Final Upgradation Steps.

Please follow all the steps with extra care and donot miss even a single step.

  • Also, this upgrade can only be executed on unlocked boot loader devices, and is not for devices which have model number P920.
  • We would advice the users to first take a complete backup of the existing ROM by using Nandroid Backup and Restore App.
  • Important data such as SMSContacts etc.can also be backed-up on PC or any other device .
  • Also make sure that yourLG Optimus 3D is at-least 55% charged as the upgrade will be done on the battery power.
