I've recenlty came across a problem, basically i was receiving a message on the display of the phone "ethernet disconnected", i've change cable, i've changed port on the switch with no luck. Searching the web i found a combination to factory reset the phone. After resetting the phone, the phone doesn't display anything. As soon as i plug the power cord the red and green led blinks and can't see anything on the display.
I think i've erased everything on the phone. I've tried also some suggestions on the internet to reinstall the firmware using tftp also with no luck.
Could you please assist me step by step how to bring this phone back to life
