The LG Optimus Black P970 is receiving official ICS update though it is too late for LG to roll out this update. It has been reported that these updates are rolling out in a few countries now and there is no idea about when this update will be available in your region. To check if it is currently available for your region, go to Settings > About phone and tap “Check for updates”. If an update is available for your device, you should see it as a notification. Just download the update and install it via WiFi. Installation of these updates will wipe all data on your device so please make sure that you backup everything to your external memory.
In case you do not receive any notification of the OTA (Over The Air) update, we’ll let you know how to install this update on your phone using a KDZ updater, thanks to the folks at XDA for providing a flashable KDZ file and a zip file for this update.


  • Back up all apps using ASTRO File Manager. You can get the APK files using ASTRO and later restore it. Rooted users can use Titanium Backup which also backs up data along with the apps.
  • Back up all contacts to SD card.
  • Backup SMS on Android.
  • Backup call log on Android.
  • Have minimum 60% charge on your phone else you might get stuck while the update process is running on your device.
  • Remove any security or Anti-virus app if you have them installed.
  • Enable USB Debugging. This can be don by Settings>Applications>Development and making sure that USB Debugging is checked.
