Before starting it would help if you had a flat head
screwdriver or a key. To disassemble your Cube place your finger on one of
the edge pieces of the top face and pull it up a little bit, just enough to
fit your screw driver or key under. Now take the screwdriver, or key, and pry
it under one the edge piece. Gently pry out the piece with the
screwdriver or key. Once one of the edges is out you can easily disassemble
the entire face. I wouldn't suggest taking apart the whole cube as it is very
hard to keep the centers lined up on reassembly. I would suggest only
disassembling the faces that need the corner, edge piece, or center that was
in an illegal position fixed. To reassemble your cube you need to put it back
together solved so each piece you add in make sure it is in its solved
position. First put the center pieces back in the tracks of that center ball
thing, then add a corner on one side, the adjacent edge piece to that corner
on one of the sides, and then the corner on the other side of the edge piece.
Now add the other edge pieces next to the two corners. To solve the last 4
pieces can be tricky. First put in the two corners, then one of the edge
pieces. To solve the last edge piece place one side of it in the "track" or
whole that it needs to fit in and gently snap it into place. Just
remember that the more you disassemble your cube the looser the pieces get so
try not to disassemble it very often.
