Go to X-Term and run

apt-get -d install --reinstall -d mp-fremantle-002-pr

Replace 002 with your product number, "002" is for USA. You can find it in Settings/about the product. Answer "y" to questions and don't worry that it is "going to install" - the parameter "-d" prevents installation.

Look package ".deb" files in /var/cache/apt/archives
