Now that you have upgraded the firmware, make sure that you replace:
In both the XMLDefault.cnf.xml and the SEP001956A3C492.cnf.xml files otherwise it won't work. If that doesn't help, try and find the latest v8 firmware files as both the XMLDefault.cnf.xml and SEP001956A3C492.cnf.xml file structure is reported to work with that revision.

It won't let me edit the settings manually. Why not?
There is a reason why these things go so cheap on eBay! The Cisco 7970 isn't a true VoIP SIP phone, they are designed to work with a proprietary network terminal control protocol known as the Skinny Client Control Protocol (SCCP). The SIP firmware made available by Cisco doesn't convert them into a fully functional SIP phone, it simply allows them to use the SIP protocol but you still need to configure it via TFTP using XML files. Their features are limited when running SIP firmware and they cannot be configured through a web based GUI or via the device directly.
As I pointed out here
, Cisco have NOT released a detailed breakdown of the workings of the 7970 configuration (SEP<mac>.cnf.xml) file. This is because Cisco now generates the SEP files from within Call Manager (CCM). This makes it extremely difficult to configure because the exact structure of the XML files isn't known and can change from one firmware revision to the next. If the structure of the XML files isn't spot on, the phone will not apply the configuration.

Please keep in mind that the 7970 is ***EXTREMELY*** sensitive to errors in this file. If there are ***ANY*** errors in the file, then the phone will simply refuse to load it. If you have never configured this phone, it will just act like it has no settings, and will likely display "Unprovisioned" on the screen. If you have previously configured this phone, the phone will revert back to the last settings file it successfully loaded. The symptoms you will notice if this is happening is that any changes you make to the configuration will not take effect. There will also be an error in the status messages.
I don't have a Cisco 7970 and my budget doesn't allow me to purchase one so i'm unable to test further and come up with a working configuration.
