Hi David,
The --recover command erases the flash memory and then writes a small binary into the recovered flash memory. This binary prevents the readback protection from enabling itself again after a pin reset or power cycle.
See http://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.6.1/nrf/ug_nrf5340.html#readback-protection 
Best regards,
Marjeris
