You can now try out the LED notifications on Lumia Windows Phones such as Lumia 730, Lumia 830, Lumia 930 and 950s. Earlier the hack was a little bit difficult to implement. However, thanks to the developers, we can now enable LED notifications within a few minutes.

Windows Phones such as the Lumia 730/735 have the LED notifications feature. However, for some reasons, Microsoft has disabled the feature by default. You can enable it by editing the registry.

How to enable LED notifications on Lumia – Method 1

  1. Download the official and latest cab file for Lumia 730/735/830/930 from here. (It is for devices running Anniversary Update).
  2. Download the official and latest cab file for Lumia 950 from here. (It is for devices running Creators Update).
  3. Download and extract it on your PC.
  4. Create a new folder in C drive and rename it to cabs. It should be like c:\cabs
  5. Put the cab file you downloaded in the folder.
  6. Navigate to iutool extracted folder in cmd with admin rights.
  7. Connect your phone to PC using the USB cable.
  8. Type “iutool -l” to see if the device is successfully connected.
  9. After confirming that you have put the cab to a new folder like c:\cabs
  10. Then type: iutool -V -p c:\cabs
  11. It will ask the Windows phone to install the cab and start the update.
  12. You will get error 0x8024a110. You can ignore it unless until your device reboots and go to the flash mode. It might take a few minutes, please be patient.
  13. If the LED Notifications is not working, download the Interop Tools from the Windows Store.
  14. Open the Interop Tools on your Windows Phone. Choose test purpose on the welcome screen.
  15. Now click the hamburger menu.
  16. Click on Tweaks > Notifications.
  17. A new screen will appear and here you will need to click on the Bell/Notification Icon.
  18. Done, you have successfully enabled LED notifications.

    What’s the benefit of using this option, and what’s the dangers in case you failed on method setup.

  • Do this method actually works, I read on xda that if you enable this on the lumia 950 you wont be able to use windows hello, is this true?

  • Juan Carlos Gebhardt Rubí

    Does this really work on mi Lumia 930 ???, cause a I did it last time with the other Tutorial from back in November 2016 and it Never Worked !!, till now I haven’t seen a Lumia 930 Notification LED Working !!!

    I was getting the same error and was just about to give up. The biggest hurdle of this working is to be able to write the new key in the registry. I ended up using interop tool version 1.9.370. Make sure you are in developers mode.
    You need to install and follow these steps:
    1. Microsoft VCLibs, NET.Native.Framework and Runtime files.
    2. Install the InteropTools.Providers.Registry.RegistryRTProvider and
    InteropTools.Providers.Registry.NDTKProvider files
    3. Interop Unlock using the App by clicking Restore NDTKSvc
    4. Import the REG file using the Interop App. Make sure it adds the key LedAlert including the values and reset the phone to take effect.
    5. Now you should have the led option in notifications.

    Hope this works.
