Official Android 4.0 Ice Cream Sandwich for LG Optimus Black P970 now available [How to]

The official LG Optimus Black P970 Android 4.0 Ice Cream Sandwich update, dubbed as Android 4.0 V30B, is now available to most of the users in European countries. While third-party developers have been developing custom ROMs for this device and have released several firmware based on Android 4.0, many would still want to use the official firmware especially the ones who are not into taking greater risks in flashing unofficial ROMs.

It will, for sure, be made available to other regions as the roll out has already been started. However, LG didn’t release a roadmap as what country is going to receive the update next and when. For owners who can’t possibly wait for it, there is a manual way to update LG Optimus Black P970 with the official Android 4.0 Ice Cream Sandwich. Continue reading below as we will walk you through every step of the way.


  1. It is strongly advised you backup all your data including your contacts, internet settings, SMS messages, videos, files, etc. We have our separate guide on how to backup an Android device.
  2. Disable your antivirus and other security apps installed in your device to prevent interference from them.
  3. Enable USB Debugging in your device: Settings => Applications => Development => USB Debugging.

Step-by-step Tutorial

Step 1: You will need to download KDZ file to start with the process. This is an executable file that contains all necessary files needed for this update. Depending on your connection, the download may take a little more time because it reaches up to 333MB in size.

Step 2: Open the application and set Type and Phone Mode to choose the correct .kdz file in your computer.

Step 3: After the software is launched, you just have to wait until the update process is completed. It may take, at least, 5 minutes to have the update installed.

Step 4: Once the process is completed, check the version of your device’s firmware to confirm whether it was successful or not: Settings => About Phone.

There are two most common issues reported by owners who recently updated: the device doesn’t boot up or doesn’t show the home screen. The common workaround is to take the battery out and re-insert it then reboot. It should work this time.

For now, there is no information whether or not LG Optimus Black will receive Android 4.1/4.2 Jelly Bean updates. So while this update is ICS only, it is not bad at all.
