I got DFU working again. Thanks.

PS: If you others have the same problem, they should make sure that they do not have an old version nrfjprog.exe. Download the newest version of nrf-command-line-tools.exe and the give it a go.

Probably because nRF Go Studio is ancient - so was never designed to work with the nRF52840 ?

If the debugger happens to be a JLink, you can use nrfjprog.exe directly from the command line. This program is in the command line tools download.

I have some trouble getting my nRFgo Studio to work correctly with NRF52840 and JLink programmers - the command line tools work just fine.
