I did try to update my firmware on Cisco 7941, I have upgraded the phone succesfully to 8.3.1 firmware, but this firmware didn't register to my IINET Voip router.
Thats why I tried to downgrade to the 8.0.3 firmware, because I read that this is working fine.
The firmware was loaded well from the tftp-server, but now I have the problem of the upgrading screen.
I tried already to restart the phone by pressing # and 1234567890*#, also tried for factory reset but this results in the same screen after starting up.
I see the phone is getting an IP-adress, but is not getting any files from the tftp-server again
I really need to get this fixed..Does anyone have any ideas?
