OpenGLES 2 without shaders

Probably the title of this question sounds a bit off.

I'm trying to follow this tutorial http://ogldev.atspace.co.uk/www/tutorial02/tutorial02.html it is for OpenGL 3.3 but I suppose that I can learn a lot from it. So I'm trying to translate it in OpenGLES 2.

The author, speaking about the function glEnableVertexAttribArray(0); says:

In this tutorial we are not yet using any shader but the vertex position we have loaded into the buffer is treated as vertex attribute index 0 in the fixed function pipeline (which becomes active when there is no shader bound). You must enable each vertex attribute or else the data will not be accessible by the pipeline.

This is the first time that I try to use OpenGLES 2 without shaders. It is possible?

Well, as far as I know it is not possible to neglect shaders in OpenGL ES 2.0 Applications. In contrast to OGL ES 1.1 the fixed function pipeline was removed. That is why everything (fragment/vertex processing) has to be done by custom shaders. Fur further details see: OpenGL ES Overview
