How to use the Device Unlock App for a LG model

How does it work?

Instead of entering an unlocking code to unlock the phone, your device will be unlocked directly by the network. There's no code to enter.

When ready, we will notify you by email that your LG device has been unlocked.

You then need to do the following:

  1. Connect your LG phone to WiFi
  2. Open the 'Device Unlock App' from your phone
  3. Select 'Permanent Unlock' option
  4. Next, the device will check it's status on the remote server.
  5. Finally, select re-start, after it will be unlocked

Below is a simple video guide showing this:
