I noticed that I had a bunch of connectors stuck the first time I tried to diconnect. Turn out I had thin layers of grit/dirt whateves under the tabs you need to press down on to release the latching. goy an new long dry long bristle toothbrush scrubbed vigorously an hit with compressed air. now I could feel the latch release..but stll to tight. got a plastic spudger and wedged it between the socket and connector while press the latch...POPPED right off.
