I am using i386 architecture of Ubuntu 12.04,I downloaded latest kernel 3.12.7 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12.7-trusty/ & installed it using dpkg -i. Installation was all good, but after 40-50 minutes it freezes. So, I would like to revert changes. How to uninstall the latest kernel 3.12.7 which I downloaded using dpkg command ?

Here's my `dpkg -l | grep "linux-[a-z]*-"

Just use apt or your favorite package manager to search and uninstall the packages.

apt-get remove packagename

Or use Software Center or Synaptic package manager and search for linux 3.12

That was simple, thanks! I have to run sudo update-grub though :) –  user236329 Jan 16 at 4:33

You could try using sudo apt-get --auto-remove purge linux-generic*3.12*. Please note that, although wildcards tend to work will with apt-get, they don't work too well with dpkg directly (at least, not as far as I can tell).
