I'm developing a simple app on a LG webOS smart TV. Since I had no luck running my app from the usb drive, I'm trying to use the developer mode from Eclipse IDE. The thing is: I've added a new target configuration, pointing to the physical TV ip. When I try to connect, a passphrase is required. I've tried something like 123456 A pop up appears: "Please verify the properties on the target and also make sure the key server in Developer mode app is ON in TV"
How do I enable Developer Mode on these TV?
With webOS 2 only some specific TVs where enable to debug and run apps on 22 January 2016 WebOS 3.0 released.
Now you can create an account and then install from LG Content Store the developer mode then when you connect your IDE or Cli the tv will give you the passphrase.

If you are connected with same network you can do remote deployment from webOS TV IDE. First you need to create a developer account from https://webostv.developer.lge.com/login
