You can obtain one of the following pictures: all corner pieces of the up face are turned incorrectly or

a) 2 adjacent pieces are turned wrongly

After repeating this procedure few times, everything will return to their places. Before doing this, locate the second "wrong" piece to the right corner. Depending on the case, you should rotate upper face necessary amount of times to locate "wrong" piece on the right corner.
