How to solve a Rubik's cube - Step 4

Step 4.

In the beginning of this stage you should have 2 created layers. Rotate the cube like in the figure.

In the end of the stage the squares of the cross should be on their place. At the same time their colors can be reversed.

You need to rotate center pieces of the up face till they will be in their place. It's not important how they are turned!
