oh and by the way: it happens to me by the 4x4x4 that i cant´t do normal F2L after pairing the edges. the colours are switched so that they don´t fit in their slots... Any ideas for that?
Are your centers in the right places?
yes...and all edges are paired...
fail, your centres are wrong. get a 3x3 and compare them.
