Following up on FFU not properly signed error

Hi everyone, I'm getting the "The FFU file is not correctly signed or not signed for this device" error. My Lumia 625 RM-942, originally used product code 059T780. After using the HEX file from ATF I succesfully came into the red NOKIA screen. I've not been able to proceed from there.

I'm willing to try out anything you tell me to.

This is what I've already tried and fails;

The only things I'm able to do is to power off the device via the command:

thor2 -mode rnd -power_off

The following is the error I'll receive when tryingto flash any FFU;
