Yes, you do need to rebuild and deploy. Reimaging erases the code that was on the robot.
Looking at the
change list, there may be a few minor changes you might want to make. You should not need to start a completely new project.
For example, from item 3, if you were counting on the gyro gain being 0.0125, you would need to add the set gyro gain VI. The other item you might want to implement is to remove the gyro close (second to last item).
