I picked up one recently for really cheap, but I struggled to get the LG 360 CAM Manager app to connect to the camera. Turns out that a certain range of app versions work with a certain range of firmware versions. I suspect that it has something to do with the latest app expecting that the camera to support 3D/spatial audio recording which mine didn't. To fix the issue I had to install "LG Bridge" on the PC and connect the camera though USB to the PC. Then through the application I initiated a camera firmware update. Luckily LG still had the latest firmware on their servers. You can uninstall "LG Bridge" after the update. After the update you can follow the steps in the original guide and the latest app should be able to connect to the camera.
