Re: Problem Update and install local Pack in UC520

Hi Jean Paul,

Firstly please follow the below instructions, if still failing please respond back.

  1. Disable or turn of any Firewalls or Antivirus programs
  2. Make sure that you are directly connected to the UC
  3. Turn of any TFTP/FTP clients/server running in your system if you do have any
  4. Make sure the UC is not connected to any network or switch, I.E keep it naked
  5. Before you start the upgrade process make sure the UC has fully loaded, look down the bottom left hand corner of CCA and make sure that it has stopped loading the voice data and any other information

If possible try and do this on a Windows XP machine that has nothing installed, basically a very basic thin XP install, this what I call a staging machine and is ideal for all CCA based builds.

Hope this helps you
