Solving the top layer’s corner pieces

When you have finished orienting the top layer it will appear to be in one of the below given patterns.

Whatever the pattern you get, just hold the rubik cube's top layer as in the picture above. Do the given move. Say, You got the second pattern with six yellow facelets on the top just hold it like in the second pattern and do the given move. If you again get pattern four, carefully watch how it's kept. Hold the cube the same way and do the same move again. This is done until you get all the nine yellow facelets on the top. Maximum within four time you will get all the nine facelets on top. In this move consider green center as the front.

Finally if you have done correctly as above said, will get the top layer with a single color. The cube will look like something which might similar to the below given picture. Don't worry about the corner colors. We can orient them in the next step.
