Hey thanks I guess I should probably be more specific in how I'm trying to solve the cube. I would like to solve the whole top layer, then complete the bottom outside layer, and then use a facelifter algorithm to solve that center. Then just use algorithms that bring edge pieces up or down to there correct positions, and finish the centers last. The two edge piece algorithms that I used on the 4x4 were Front 2x, Bottom Middle panel to left, Front 2x, BM 2x, Front 2x, BM to right Front 2x. I use this algorithm to lift flip flopped pieces that are under the place that they need to go up to in the 2nd layer. The final algorithm I use for solving the 3rd layer is turn the third layer so only one piece is oriented correctly and Back to the left, Bottom 2x, Left down, Bottom Left, Left up, BM to the left, Left down, Bottom to the right, Left up, BM to right, Bottom 2x, Back to right. I'm sorry, I'm not very good with notation, but now I have the cube where bottom and top layers are done all the centers are done, and I only need to finish all three edge layers. I went ahead and did the centers just to see if I could do it. Thanks again now I have a little hope that I can do it but still need help.
