You can find more information about the Debug in/out port here and here.

Note that if you have done any modification to the solder bridges, you should restore them to default state.

Have you tried a different USB cable? Faulty cables are surprisingly often the issue.
Can you measure the supply voltage on the nRF Device? The error indicates that the debugger is not able to detect the device, and is normally shown when there is a mechanical issue with the wiring or connectors (a contact issue).
Can you try this guide? devzone.nordicsemi.com/.../

Thanks for your continued efforts.

I tried the bootloader.

Unfortunately there was no difference.

Just checking I am doing it right:

Hold BOOT RESET
Connect USB to External Supply (not nRF USB)
File Explorer displays Bootloader folder
Drag bootloader .bin file onto drive.
Once file is copied Bootloader folder disappears and LED on dev board flashes.
LED continues to flash until USB cycled
Board appears as JLINK drive on PC

At this point I would expect to be able to erase the device using nrfjprog -e or program it by dragging the ble_app_att_mtu_throughput_pca10056_s140.hex file onto the drive and cycling the USB. Neither works.

I have pasted the latest log outputs much further below.

Question

Can you please point me towards where I can find more information about how to copy from one device to another?

I've found P19 and P18 and can get a cable made up.

Not sure what the process is.

Try to use version 170724 of the nRF5x-OB-JLink-IF found here.

If it's still not working, you can try a different computer.

You can also try to program the kit that have the issue, with the kit that is working. If you have 10-pin cable, you can connect the cable to debug out(P19) on the kit that is working, and connect the other end of the cable to Debug in(P18) on the kit that have the issue, and see if you are able to recover the board.

Try with nrfjprog.exe --recover -f nrf52 --log , and see if that makes any difference.

This worked " 4.Have you tried to press the IF BOOT/RESET button while power cycling the kit? It should then show up as a Removable Storage Device named "BOOTLOADER". Then you can drag-and-drop this file onto the storage device to reprogram the JLINK firmware. "

I can now see the device. But ... I get errors when trying to use nRFgo or command line. Here's the output from log.log

Hi,

Try the steps desrcibed in this post to recover the board.
