I have a 7971G-GE that locked up in the middle of a firmware upgrade. When I plug in the power brick the "Headset", "Mute", and "Speaker" buttons light in sequence and the "Speaker" light stays lit but the phone does not attempt to get an IP address from my DHCP server or talk to the network in any way. I have verified this with a sniffer, and I have other phones working so I know my network is configured properly. I have attempted to do a factory reset by holding down the # button and powering up the phone with a power brick but the line lights never flash, even after holding the # button for 10 minutes. I connected to the phone with a serial cable and pasted below the output I captured during boot. It appears to me that the file system has become corrupted. Can anyone verify this and point me in the direction of correcting the problem. Thanks in advance.
