Hello, I'm having the same problem. I have a Cisco IP Phone 7962G. After I perform a Factory reset by performing the steps described mpaneers that, my phone is not displaying the screen image. Performed all the procedures you have written on this topic, but none of them worked. I tried with firmware versions: cmterm-7942_7962-sccp.9-2-1 and cmterm-7942_7962-sccp.9-3-1SR4-1, but none worked. I realized that the phone was trying to get 2 times the file "term62.default.loads" TFTP, but in no time sending was complete. I found something that struck me as odd. I did a packet capture with Wireshark at boot time the phone after doing the process of pressing the keys "123456789 * 0 #", and realized that the TFTP acknowledgment packets sent by the phone are with the value "0x00000000" in the field FCS frame layer 2. I think this may be a problem. Attached is a picture of the catch taken in Wireshark. If anyone can help, I will be very grateful. Thank you.
