Maybe the chips is not connecting to the adapter pins properly. I have just tried a near identical chip in my GQ and you can see by the screen shots it works OK.

NOTE: My chip is slightly different to yours, mine is 29LV800CT hence why chip ID is different.

Hi I had a problem with writing, but could read ok, no id,
I found the problem was with the soldering on the ZIF socket inside the programmer, use a multimeter
test all pins from the zif to the sockets that plug on to the pcb programmer pins,

No need to open up the programmer to test it, you can simply use the software...
