Yeah,but what i found it is more for zbrush,i need help for blender!

You should not be so blinkered by limiting yourself to a particular piece of software used in the tutorials. The point of tutorials is not to blindly follow them but to understand the concepts shown which you can then apply to the particular piece software you are using.

If you are incapable of doing this, you really should be going back to the beginner tutorials to understand the basics of using blender. Understand the basics to use as a foundation, then you are in a position to apply that to modelling anything

Thanks,but do you think that is better to create all the bricks or create the wall from a texture?

It is a matter of detail that you need for the screen. If the wall is close to the camera, I would represent the stones with geometry. You can do this with individual bricks or with a displacement map on a highly subdivided objrct. If the wall is some distance from the camera, I would use a bump map or normal map texture on simple geometry.
