Position the cube as shown in Figure 4 such that Side 2 is facing you. Perform Move 2, then return to the start of step 3.

Move 2: U-1 F2 U F   U-1 F U F2

In words, rotate the upper side (red here) one quarter turn counter-clockwise, then the front side (white here) two quarter turns (half-way around), then the upper side 1/4 turn clockwise, etc.

Position the cube as shown in Figure 5. Perform Move 2, then return to the start of step 3 only if the four corner pieces of side 2 are not oriented correctly. If they are correct, as shown in Figure 8, go to step 4.

Position the cube as shown in Figure 6. Perform Move 2, then return to the start of step 3.

It is not possible to have 7 corners oriented correctly while just one is incorrect. If your cube is in fact like this then it has been disassembled in the past and incorrectly reassembled. You will have to disassemble it again and reassemble correctly.

Step 3 may need to be repeated numerous times. Also, the move directly before all four corner pieces are oriented correctly will have just one piece oriented correctly, as shown in Figure 5 (step 3b)

• This does not mean, however, that you will always achieve Figure 8 when just one piece is oriented correctly. Again, just keep repeating step 3 until Figure 8 is achieved. It will happen, trust me. Move 2 is sort of a black magic move, but it works.
• If you end up performing Move 2 over 10 times, either some of the corners on side 1 (the blue side) are incorrectly twisted or you're not setting up the cube as shown in the figures.

NOTE: To achieve the image shown in Figure 8, the slice containing middle-center pieces 3, 4, 5, and 6 may need to be rotated. Side 2 may also need to be rotated.
