I have trouble with that edge. Please give algorithm or images for solutions for turning it up so that I can form a cross.

The algorithm is

$r \ U^2$ - X - $r \ U^2 \ r\ U^2 \ r' \ U^2\ l \ U^2 \ r' \ U^2\ r \ U^2\ r' \ U^2\ r'$

Where $r$ means you have to turn two layers from the right upwards and $r'$ means downwards, $l$ means you have to turn two layers from the left downwards. and x means you have to turn the whole cube one face upwards.

Initial

$rU^2$

enter image description here

$\times$ one face up

enter image description here

$rU^2$

enter image description here

$rU^2$

enter image description here

$r'U^2$

enter image description here

$lU^2$ remember left down!

enter image description here

$r'U^2$

enter image description here

$rU^2$

enter image description here

$r'U^2$

enter image description here

$r'$

enter image description here

Now you can solve the top layer.
