Cisco SOS Recovery Process #
If your Cisco handset experiences an interruption of power during a firmware upgrade then the firmware could be unusable. If this happens then the handset will display “SOS phone in recovery mode”.
The handset will automatically try to get a valid image from the last source that it can remember. You can however manually recover a handset from this stage using this recovery utility supported by Cisco.
This is Cisco software and Gamma has no input into this.
When the handset attempts to access the “last upgrade URL”, it will be unable to handle a recovery request from the PC. When the handset gives up, it will allow you to use the recovery utility successfully.
Step 1
Make sure the default TFTP port (69) is not occupied on the computer. For example, if you have a TFTP server such as Pumpkin or Solar Winds running, shut the TFTP service down.
Step 2
You might have to disable the firewall or other security measures on the PC to allow TFTP to function properly.
Step 3
Run the recovery utility and enter the handset’s serial number when prompted. You can use “FFFFFFFFFFFF” (12 ‘F’s) instead of the handset’s serial number.

Step 4
The recovery utility should find the handset in recovery mode. Follow the instructions on screen to start the recovery process.
Once the handset has recovered and rebooted, you can upgrade to the desired version of firmware.
