Thank you buddy. It worked. I used the nordic dev zone linked which you gave. I dragged and dropped the bin file for the j-link and then used the configurator to update the FW. THank you very much.

The process is the same for usb or lan. You can either read through the segger docs to learn how to restore the j-link firmware or if you like this nordic blog discusses restoring the segger code from a nordic point of view: devzone.nordicsemi.com/.../

You didn't answer the question. Does it or not show up in the configurator? If it does not show up then follow the info on this link for restoring the segger code: forum.segger.com/index.php

THank you for the reply. I have connected my board to the PC via USB. then I opened the J-Link configurator and I am not able to see any update in the software. If you turn on the device(PCA 10056) using on-off button then the LED 5 is not blinking. But if you press the RESET/IF BOOT pin and then switch on then the LED 5 starts blinking. THe blinking interval is 1 second.

If you are using the current version of J-Link (according to their website it is 6.22d) and you have tried everything in my above comment and it still doesn't show up in nRFGo, then follow the instructions in the following post for recovering your segger: forum.segger.com/index.php

I doubt it. First try different usb cable. Then see if it shows up in Segger J-link configurator. From there you can select it and choose update firmware. Which version J-link do you have installed?

Do you think the board is dead now? As I am not ale to load the code?

I do not believe it is possible to erase (ie, brick) the segger software. Try re-installing the segger software. Just run the updater for the current version of J-Link. Also, you can try doing an uninstall/reinstall from device manager.
