by mistake I deleted the flash memory I reinstalled the IOS in order to install the software package UC520-7.0.3.zip
the problem is when I attempt to upgrade using the Cisco configuration asistant application in the 49 per cent of the ipgrade proccess the installation failded indicating the following error:
Backup of CUE configuration and data failed.
Software upgrade for CUE module failed.
any help will be good
You may have an FTP server running because of which CCA is not able to backup the configuration. Can you capture the complete application log for upgrade?
Make sure you meet all these prerequisites and starting point for CCA connection...
