Selective decoder readout in Q Programmer


With some of my OEM Q2FX LS and DO (7021, 7022 hardware) decoders I can readout CV values using Q programmer without issue
With others of the same version I cannot retrieve the data and get the 'cannot read I.D.' error.

Is there some workaround I can perform on those that error to at least overwrite the firmware with a new file? Is it possible (or probable) the programmer has an intermittent malfunction?
