Switch V2 pycofly / no signal to TV

Hi, I'm having a V2 device and I can't connect it to the Tv. When I put it on dock there is no signal to the Tv. Tested the dock with a V1 device from a friend and it's working fine with that device. When I put my device it's showing that it's charging , the green led from dock it's lit and that's all. On the device at TV output settings I have only Automatic and 480p option. My friend on his modded V1 has all the Rez options including 1080p. Tried to change the Hdmi same issue. Please help me.
