I had to reset this 7970 phone and reload the firmware using TFTP server on the notebook and the phone start working again when connected to the network. The problem is; the only firmware that I can loaded to this phone is the old firmware (8.0) and always fail when it try to upgrade to the current firmware that is in UC (9.1). I tried to upgrade using the TFTP server again on the notebook but never work. Any advise?
You need an intermediate firmware like 8-5-2S before upgrading to a 9.x version. As you are on an 8.0 version so even getting to 8-5-2S may require another intermediate version like 8.3. So, it will be a two or three step upgrade to 9.x firmware.
