Roll back cable box update?

Is there a way to roll back the update to the cable box software which took place a couple of months ago?  The new guide search feature is very frustrating.  Before the update, when a program was highlighted on the guide, you could press guide again and that show would be filled into the search by default, thus making it easy to see what other times and channels  that program would be on.  Now it defaults to a blank search field where you have to enter the whole program name to see what other times it will be on.  An "update" should make something more user friendly, not more of a pain.
