I tried it and it didn't work. The problem is that when I do the first two steps, I have a white cross and the other sides are not done which makes it impossible to solve it just using your instructions. The proper way to solve a rubiks cube would be to start with the white side, then fill in the second layer, then do a yellow cross on the top that lines up with the middle of the colors on the sides, then to fill in the proper corners.
