By now, all 4 bottom corners are in the bottom layer. There are only 8 corner pieces, and the first 4 are already on the top, forcing the last 4 to the bottom. The first step is to arrange them in the correct positions:
Turn the bottom layer |
Now rotate the entire |

Repeat this |

What the move does: |
You may have to repeat the sequence twice to fix the front bottom corners in place.
For you experts, there are variations to the prior sequence that yield powerful results. There is no need to memorize these, but if you want to save a few moves, here they are:
Sequence: |
Result: |
B- R- B+ L- B- R+ B+ L+ B2 |
The same 3 corners are swapped counter-clockwise. |
B2 R- B+ L- B- R+ B+ L+ |
The (bottom) right 2 corner cubes are swapped. |
B+ R- B+ L- B- R+ B+ L+ B+ |
The (bottom) back 2 corner cubes are swapped. |
The two front (bottom corner) cubes should now be in place. The back ones may also be in place; but if they are not, swap them with the following move:
B+ R- B+ L-
| ||
Swap the lower back corners |
You only have to do the sequence once to swap the rear bottom corners in place.
All 4 bottom corner cubes are now in place. The next step is to rotate each corner so that their bottom sides are the correct color. In the worst-case scenario, no corner cube has a bottom side with the correct color. In this case, do the following move:
R- B- R+ B-
|
You only have to do this once. Now there is at least ONE corner cube is finished, with the right color on the bottom side.
Rotate the entire |
Repeat the move: |
...until both front | ||
R- B- R+ B- |

You may have to repeat the sequence twice to finish all four corners.
It is now time to solve the Bottom Edges.
