I got a 7975G that was interupted during a firmware upgrade. Therefore, the screen is disabled and I cannot see to get it to come back on or upgrade. It will get an ip address from the TFTP but it does not appear to try to download anything from the TFTP. And even though it has an ip address I cannot get to the phone's web page. Can anyone help me figure out how to get the screen back on and get this phone back up and working?
Did you try to perform factory reset procedure?
After that you can try to upload the firmware through a tftp in a windows or linux machine.
Let me know

Yes, I have tried the factory reset procedure several times. Since I can't see anything on the screen I can't see if there are any prompts for me to do. Yes I have tried a TFTP server on my windows pc and pointed the option 150 to that ip address. According to the logs in the tftp the phone is not trying to download anything.
No, I'm not sure if it is getting the TFTP because I can't see the screen or the web page of the phone. I'm using a 871 router for the DHCP and then using TFTPd64 for the TFTP on my pc. I plug the pc into the same 871 and it gets an ip address and can ping the phone.
Thanks for helping Brian,
Again, I am not using the DHCP on the TFTPD64 but I'm using the Cisco 871 router for the DHCP. It is currently defined as option 150 ip x.x.x.x. I am using the TFTPd64 only as the TFTP server to try to get this phone up. I have the firmware files downloaded and set as the base folder for the TFTP. Do you think I need to set option 66 on the DHCP on the 871? Any other suggestions?
