Can't flash PCA10040

Jonas0

Hi, 

I can't flash my PCA10040 dev board.

I get this when I connect with J-Link Commander:

Connecting to target via SWD
InitTarget() start
CTRL-AP indicates that the device is secured.
For debugger connection the device needs to be unsecured.
Note: Unsecuring will trigger a mass erase of the internal flash.

Executing default behavior previously saved in the registry.
Device will be unsecured now.
InitTarget() end - Took 4.11s
Connect failed. Resetting via Reset pin and trying again.

Executing default behavior previously saved in the registry.
Device will be unsecured now.
InitTarget() end - Took 4.11s

When I run nrfjprog --recover I get this:

What might the issue be? Seems like it is locked somehow.

    Could you execute "nrfutil upgrade" and then try again?
