was able to follow the problem until following addition to Texture.cpp:

// GLES doesn't cope with internal formats of 1,2,3 and 4 so map them to
the appropriate equivilants.

if (_internalFormat==1) _internalFormat = GL_ALPHA;
if (_internalFormat==2) _internalFormat = GL_LUMINANCE_ALPHA;
if (_internalFormat==3) _internalFormat = GL_RGB;
if (_internalFormat==4) _internalFormat = GL_RGBA;


The problem is that internal format "1" corresponds to GL_LUMINANCE, not
GL_ALPHA. I double checked this from the Red Book. Fixed version is
attached to the email."
