7960 was giving error "Load Authentication Failure" when starting on CCME 4.0 system. So we tried a reset (hold # key down when cycling power then 123456789*0#) but now it hangs with lines keys flashing green. I can't get it to boot at all! No screen, no messages - nothing. Even tried factory reset (hold #, power on then 1673492850*#) lights flash red but then go back to green. Any ideas?
Other phones (7960 and 7940) are ok on the same system.
If this is happening with only one single phone and all others are working fine, I'd suggest opening a TAC case for this. It could even be that the phone is faulty or ur trying to load unsigned load (3.x and below) on a phone which would only take signed loads (5.x and above)
Our phones are setup on a CallManager Express system using 2 vlans (1 for data and 1 for voice). It would appear that when phone got stuck in this reboot cycle that it was obtaining an ip address from data vlan and not from voice vlan as it normally would. Thus it could not find tftp server on voice network. We put a tftp settings into the dhcp server on data network and phone found new firmware and completed reboot!
