If in your original theme you had changes in the header, footer, or in any other file such as functions.php, single.php, archive.php, e.t.c. You had to copy those changed files to the directory of the child theme. And yet it is not correct for you to modify so many files if you can use hooks inside functions.php. And after having done that, you could update the theme. Otherwise you would lose all the changes you made in the parent theme.
