It’s hard to say what exactly the issue is since the -1 and -102 are generic error codes returned by the JLinkARM dll for which Segger's documentation offers no specific explanation other than that an error has occurred.

Somethings you can try:

Try this command before you flash your firmware: nrfjprog.exe -f nrf52 --recover --log
Can you measure the supply voltage on the nRF Device? The error could indicate that the debugger is not able to detect the device, and that there is some mechanical issue with the wiring or connectors (a contact issue).
Can you try this guide? devzone.nordicsemi.com/.../
