I have a CP-7906G IP Phone.
I have hard resetted the IP Phone with this boot up sequence command
hold # 123456789*0#
I have also done a another settings which I think it's a factory default settings.
hold # 3491672850*#
After doing the second boot up sequence, my IP Phone screen went blank and I can't seem to do anything at all.
Please help me what I should do from here to load a working SCCP or SIP firmware.
