Purple side? What is this, a virtual Eastsheen?

Do r2 R2 U2 r2 R2 u2 r2 R2 u2 U2 and then you have a T or F perm.

If you don't know them, just do regular 2 look PLL. I assume you know how to do that, otherwise I have no idea why you did OLL...

You should be able to solve it now, if you haven't already. After the parity fix, the 4x4 is now in a legal 3x3 position.

You would have to do a y' before the T perm. (Counterclockwise rotation on the Y-axis, the unsolved corners will be on the right)

It's not a permutation... lol.

It's a rotation. As in, you literally, rotate the cube. After the rotation is complete, blue will be on the right.

When i do u2r2U2(r2R2')U2r2u2 i hold the cube like in the posted picture from the first thread. After the algorithm it is more mixed than before. When i after this do the Y' rotation, so that the blue side is on the right and then do the RUR'U'R'FR2U'R'U'RUR'F' it doesn't work. What do i wrong?

If it looks scrambled after the first algorithm, then you did it wrong. Only the top layer should be incorrect, but it should be completely oriented like it was before. Watch Lucas's java applet, it shows exactly what to do, and even highlights the moves while it's doing them.
