Thanks to both, I wil try with a wire.
@György-Farkas - by pressing the reset button duriing boot you can access a menu and choose to flash the Omega 2+ from USB even when it is bricked as I understand it.
I too now have an Omega 2+ with the Omega-0000 name. It had a regular MAC address based name until now. This happened after I upgraded with oupgrade -latest -force to 1.9 152. If I use the Omega-0000.local address the setup wizard starts.
A noob here too ) I have ordered this adapter : http://www.banggood.com/CJMCU-CP2102-USB-To-TTLSerial-Module-UART-STC-Downloader-p-970993.html
Now I notice it says RX1 and TX0 on it. Will it work for the Omega 2+?
