All in One printer problem, Can anyone help

I have hp all in one 3050 printer, I had some issues with the scanning software, so, I tried to update the firmware but after about 50% the printer stopped responding and the status through the usb cable is NOT Ready state, and the printer panel shows only HP and not responding to any keypress by the way there is an ethernet connection for this printer but i didn’t try to use it for updating the firmware. Can anyone help in this issue.
