Root and Install Clockwork Mod Recovery on LG Optimus 3D P920

Fortunately for all the LG Optimus 3D P920 users, a custom recovery image is now available, which brings the ability to install custom ROMs on the device. Please note that the recovery image file is also available for the LG Thrill, so you can follow this guide in order to install it.

We will now teach you to install the custom recovery image, and latest touch Clockwork Mod Recovery ( CWM ) on your LG Optimus 3D P920 Android smart phone.

Before you begin the process please note that your data might be corrupted or even lost so you have to do backups on order to recover it afterwards.

Backup your data

The most important data to be backed up are the contacts and media files including images, songs and videos. Though you might also backup your SMS messages, call logs, APN and MMS settings.

For the contacts we recommend you to sync them with your Gmail account. Read here how to sync you contacts with Gmail. We also recommend you to use the Call Logs Backup & Restore application to backup call logs and the SMS Backup & Restore application for SMS messages.

If you want to backup the APN and MMS settings, the easiest way is to note them down on a piece of paper. Images, Songs, Videos and any other files should be copied on either the internal or external SD card, because they won’t be affected during the installation.

Preparing to install custom recovery image

There are risks while installing the custom recovery image, so you have to read everything carefully and make sure not to skip anything or you might damage or even brick your LG Optimus 3D.

  • First make sure that your battery is at least 60% full, or otherwise the device might turn off during the installation.
  • Then you have to enable the USB Debugging on your device. To do it go to “Settings > Applications > Development > USB debugging” and tick “USB Debugging”.
  • Disable all security suites and any other antivirus software because they might interact with the installation software and stop it.
  • Make sure that your computer recognizes the device. If it doesn’t, find and install the latest USB Drivers for it.

If you are sure everything is ok then you can proceed to the next step.
