Yes, thank you very much!

I'm not exactly sure what you mean by this, but does that mean that the issue is solved then?

I've used:

nrfutil dfu ble -pkg dfu.zip -ic NRF52 -p /dev/ttyACM0 -a MAC -f

I've also found out why it appeared in the first place: the target device's proxy was turned off. I'm not sure which connectivity firmware I was using, possibly 1.2.0 with 115200 kB/s baudrate.

Error code 8 means NRF_ERROR_INVALID_STATE. As a return code from ble_gap_scan_stop, this means that the code try to stop scanning without scanning being started.

What command are you using for performing DFU? Have you erased the board before running nrfutil, to make sure you get the correct connectivity firmware?
