Nordic Board is stuck in reset

Question

On a MCU PCA10040 v2.0.0, I ran the command: 
 .
rfjprog.exe -f NRF52 --program .\final_image.hex --verify --reset 
 
 Which subsequently caused the board to go into a reset state where the LEDs are constantly flashing. 
 
 How can I recover from this please?

I looked at the problem a little further and observed the following: Using the latest SEGGER ( v7.60g) and nrfjprog( 10.15.1 external ), I am unable to program the v2.0.0 Nordic Boards. These were put into the 'reset' state using the command discussed above. 
 
 When I remove the SEGGER probe and external supply, and then plug in a USB cable, the green light (next to the MCU) is on and the four LEDs are very faintly on but I am still unable to program the board with the SEGGER and nrfjprog. 
 
 If I use v2.1.0 Nordic boards, I have no problems and can program them via the USB cable using nrfjprog.

So the problem is that it may not be the hex file but I need some help to program the older v2.0.0 boards?
