[cisco-voip] Easter Egg for phone that won't boot

[Robert Kulagowski]

I saw in the Cisco forums someone asking how to recover a phone that 
won't boot and that they tried the 1234... pattern.  They also tried 
booting with the handset off the hook to try to revert to the backup image.

Revert to the backup image?

If you happen to find a 7970 where the screen will not turn on after a 
reboot, and the line lights blink green in sequence with the Headset
button illuminated, then your CTL file system is corrupt. Here are the 
steps you need to take to format the flash, recover to the default
configuration and reload the default load:

1) Power off 7970
2) Power on 7970 (with a power-brick) while holding the # key
3) The lines lamp should blink amber in sequence, let go of the # key
4) Press 123456789*0#
5) The lamps should blink green in sequence
6) The phone will obtain IP information via DHCP
7) The TERM70.default load will be loaded on the phone
8) The phone should recover the configuration file from CallManager, if
not reset with **#** and your confriguration will be restored

If you do not have a power-brick connected, while doing the 'Factory 
Restore' then this process will fail because the 7970 cannot TFTP the
TERM70.default load from itself with inline power. If you have a console 
connected you will see:

CDP: power TLV's not detected - assume low power mode - pwr src = 1
