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.
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

When I run nrfjprog --recover I get this:

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

Hi, 

nRF Command Line Tools (nrfjprog) is deprecated and replaced by nRF Util. Please install nRF Util and run "nrfutil install device" to install the device command. Then, you can execute "nrfutil device recover" to recover (unlock) the device. 

Regards,
Amanda H.

Hi, 
I tried but got this:

C:\Program Files\Nordic Semiconductor\nrf-command-line-tools\bin>nrfutil device recover
 Failed to recover 1050340818, Device error: Access port is still protected after Erase and Reset Error: One or more recover tasks failed:

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

Herer is the output, I also executed "nrfutil self-upgrade":
