I need help with the second layer of a rubik's cube?

Question

I did the whole second layer except for one cube. The problem is, it's in the correct spot, but it's flipped so that the orange is where the green should be and the green is where the orange should be. Here's a picture in case you don't know what I'm talking about:

and btw the white face is completed on the bottom (prolly obvious but I thought I'd let you know just in case)

Answer 1

You'll need a method of swapping one of the edges on the top with the piece that is wrong. Do you have such a method? Take this piece back up to the top, turn the top through 90 degrees, then use a mirror image of that move in reverse to bring it back down to where it is supposed to be. That should do it.

Here's a swapper method, although I haven't tested it - I just did this from my head:

F U² L F L' U² F'

F = front anticlockwise
F' = Front anticlockwise
L = left face clockwise
L' = left face anticlockwise
U² = top two quarter turns

This site has a solver:

You enter the cube and it shows step by step how to solve it.
