Finishing Off

By now you should have all pieces in the right locations, but some may need rotating around. This is where you may pay if you ever took apart your cube. The cube can be made impossible to solve (without taking it apart), simply by taking one cubelet out and rotating it!

Edges

Edges that need to be flipped always come in twos. eg 2 need flipping, or 4. The first step is to get the cube so that one of the edges you want to flip is on the right hand side of the final layer. Then hold it so the final layer is at the top of the cube eg:

Now do this:
rightdown topleft bottomleft leftup leftup topleft topleft bottomleft bottomleft rightup

Now rotate the top side until there is another edge that needs rotating in the right side of the final layer. Now we just reverse everything you just did. ie:
rightdown bottomleft bottomleft topleft topleft leftup leftup bottomright topright rightup

Now rotate the top layer until it is in the correct position. Now repeat if you have any other edges that need flipping.

Corners

Again, we do corners in pairs. You can have 2, 3 or 4 corners that require rotatiing. Now there are two ways the corners can be rotated- clockwise and anti-clockwise. eg:

cube3-9 cube3-10
Clockwise Anti-clockwise

 

If you have 3, they will all be clockwise or all anti-clockwise, but after you have done this section once there will be on corner set and the other two in different directions. Now get a corner piece that needs to be rotated clockwise into the front right corner. Eg: cube3-11

Then do this:
rightdown bottomright rightup frontCW bottomright frontCCW

Now rotate the top layer so that a corner piece that needs to be rotated anti-clockwise is in the front right corner. Eg: cube3-12

Then reverse the last lot of moves:
frontCW bottomleft frontCCW rightdown bottomleft rightup

Now rotate the top layer until it is in the correct position. Now repeat if you have any other corners that need rotating.

FINISHED!!

You should now have a fully completed cube. Congratulations.
