MKL43Z new chip SECURED, how to UNSECURE it?

Hello,

 

I have just assembled a custom board using MKL43Z, with a brand new chip.

 

When I connect it to the USB, it is enumerated as Kinetis bootloader.

 

However, when I run blhost get-property 17, it returns that the device is SECURED....

 

Is that correct for a brand new Chip?? What can I do to program it and/or remove the security??

 

Regards,

Thiago

 

I have tried to unsecure it via blhost with no success:

 

 

Is the new Chip lost?
