How to Unbrick Your LG Optimus L3 E400 -Stock Firmware

You might have bricked your LG L3 during Cyanogen or other ROM installations or during Rooting process . Here is the method to Unbrick your precious LG L3 and bring it to stock. 

Note: This method can also be used by non-bricked people who wishes to to return to stock firmware. For them, just enable USB debugging on your device, Turn it off afterwards and continue with the steps as mentioned.


  • Download and install LG PC Suite & USB Driver--Link
  • Download Stock Firmware according to your country --Link ( if you didnt get the file, please refresh again and again. I had to do it for about 7 or 8 times )
  • Download KDZ updater--Link
  • Install msxml file found in the KDZ updater folder. The Restart Your PC. ( This will solve the wparam 100 and lparam 6 issue)

Let's Begin:

  • Get your device into emergency mode --->remove the battery and put is back again and then press vol UP + vol DOWN + power button at once.Then wait for a vibration. Now you will see a emergency mode written on yellow background.
  • Connect your LG L3 to your PC using USB cable.
  • Next open KDZ updater (Run as Administrator only) and select >>  Type: 3GQCT -- PhoneMode:DIAG 

  • Select the .kdz firmware file that you have downloaded in the KDZ file section.
  • We are ready to start the process. Click on the "Launch software update" , it will take some time to finish. If everything goes okay, then you will see a "Finished" message in log. Now your phone has been switched off from Emergency mode.
  • Next ,turn it on. This will also take some time. Don't worry, its normal the first time.
