Some revs of the GS firmware will wait forever for a reply from a time 
server or tftp server. If the address is configured and the phone is 
attempting to contact a server which doesn't respond, the lights never 
go out. If you can operate the menu, (you may need to cycle the handset 
off-hook and then on-hook first) set the TFTP and Time server addresses 
to 0.0.0.0 and restart the phone. If the phone now works, then you 
should be OK. Also, even if you unplugged the phone during a firmware 
update, you may still be able to get the phone operational if the 
bootloader code is intact (which is not that unlikely), but you will 
need to get a TFTP server located at the address that the phone is 
attempting to access.

Hope this helps.
