According to OpenGL ES spec: Only two combinations of format and type are accepted. The first is format RGBA and type UNSIGNED BYTE. The second is an implementation-chosen format. The values of format and type for this format may be determined by calling GetIntegerv with the symbolic constants IMPLEMENTATION COLOR READ FORMAT OES and IMPLEMENTATION COLOR READ TYPE OES, respectively.
The second supported format for emulator and G1 is GL_RGB, GL_UNSIGNED_SHORT_5_6_5. And make sure you specify correct dimensions.
