Solved the Rubik's Cube

After a half's days effort today, i have been successful in solving the Rubik's puzzle. It is really not that hard to solve the puzzle, although it looks like it is. just that you will need to have a step b step approach and use some simple algorithms to have the output. you will also need loads and loads of patience to get it done.



Steps


Step #1 : getting the first row right.

I have no clue of what algorithm to use here. i did it on my own so it should be simple.
Finnish off one side right and place it in the bottom so the completed side faces the bottom. Now we will do completion towards up.

Step #2 : getting the second row right.


Two algorithms here, left one and the right one

Left one: Ui Li U L U F Ui Fi
Right one: U R Ui Ri Ui Fi U F


Step #3: Now you should have completed the bottom 2 layers
Creating a cross on top, either from a center piece, or from a L or from a line

===> F R U Ri Ui Fi

L should face towards North West



Step #4: Aligning the cross Elements to relevant center pieces

When you complete the cross which has 'four center pieces', at least two of them will be aligned to the center pieces of the the four sides, if the aligned pieces are adjacent to each other place one aligned side on your opposite and one on right and do this algorithm, if they are opposite to each other try this algorithm to get adjacent pieces and then repeat the step as detailed.

===> R U Ri U R U U Ri


Step #5: Aligning the aligning edge elements to their positions

===> U R Ui Li U Ri Ui L

up , away from you (r) , up inverted , away from you (l), up , towards you (r) , up inverted , towards you (l),


Step #6: Super rotation

===> Ri Di R D

Note: nothing will go wrong in step 6,don't be afraid, if you repeat step 6 - 6 times, the cube will come back to its original position. also when you align one corner piece on the topside, rotate the topside anticlockwise to get a new corner to be aligned, don't rotate the whole cube when you align one corner price in step 6

After a few attempts you are done. See the completed version of my cube here.
