I have a problem with my GQ-4X. I has worked from quite some time, but now, i keep getting a verify failed when burning M27C801 (or M27C322 with the 16bit adaptator).
The main problem seems to be that D7 is stuck to +5V (check image attached for a diff between written and re-read file).

Is there a way to diagnose if this is a firmware problem which could be fixed by "reflashing" the programmer (is it even possible to do so) or if there is a component which started acting weird (a quick check shown no dead component).
Data line stuck to +5V on GQ-4X
