James, thanks for the input, as I stated below l was able to get the device in DFU mode after shortening the pins (not a jumper on this version)
found the device...
was able to load it
but as I stated below, the unit boots up after power-up reset to a blank white screen
the unit cannot be reached via the VNA-QT application
note please I have another unit that CAN be reached with VNA-QT
