      Checked with two diffirent boards of each, I have 2 mini and 2 1LC boards, always status led flashing on red....

      Checked with new set of wires also

      Can´t figure it out, to set it working.

      Powered up with 2 buttons pressed, but no change. No comm, can´t upload fw either

        dont know if its solve your problem but you have the 120 Ohm terminating Resisitor twice. Once you have the extra Resistor on the CAN Plug ( only used with 1.1 Boards without distribution boards) and then you closed the Solder brigde on the Board( 1.2 boards and later. Remove the Cable resistorand leave the cables open. At least your CAN should connect then.
