downgraded to an old version of flash how to trace what changes were made by installer

Wed Mar 23 20:47:00 UTC 2011

I was having some problem with flash player version 10.2 so I had to
downgrade it.
Based on instructions here
http://www.webupd8.org/2011/03/fix-pinkred-youtube-videos-bug-using.html#more
for 64 bit
before doing above I had taken a backup
sudo cp /usr/lib/flashplugin-installer/libflashplayer.so
/usr/lib/flashplugin-installer/libflashplayer.so.old

Now I did
wget http://archive.ubuntu.com/ubuntu/pool/multiverse/f/flashplugin-nonfree/flashplugin-installer_10.1.85.3ubuntu1_amd64.deb
sudo dpkg -i flashplugin-installer_10.1.85.3ubuntu1_amd64.deb

I am not able to find out what changes had the above dpkg thing made
to my system i.e. what additional things were downloaded and which
files it added to my system?How can I trace these changes?
I looked /var/log/apt/history.log and /var/log/apt/term.log
but to my surprise there was no information about this downgrade of
Adobe Flash player to an older version.

here is the screen output when I downgraded to an old version
dpkg: warning: downgrading flashplugin-installer from

So it appears it surely downloaded some thing but what and where that
is not clear to me.
