When I learned how to solve my 4x4x4 Rubiks cube, I learned from the booklet that came with my cube. I prefer solving it that way because I have never had a problem with parity errors EVER!!! And it has been a long while since I solved it and I seem to have forgotten the last couple of algorithms. However, it does not matter how many times I google it, people seem to only know how to solve it by solving the middles, then the edges and then like a 3x3x3. When I try to solve it like that, I constantly have some kind of parity error. I would REALLY love it if someone could give me the algorithms to solve it ther iriginal way that I learned it. Please and thank you to anyone willing to try and help me!
