Hi I had this problem on a gq-4x, it could read but it would stop writing at 6% and would not id,
I had this problem from new, it was not the adaptor or ic pins, so I opened up the unit and tested the zif socket and found no contact on pin 11, the soldering all looked good but I de-solderd pin 11 and resolderd using some added flux and now it has made good contact and is now working reading and writing,
So check all pins with a multimeter of the zif socket to pcb of the programer
Thanks Dave

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