The controller is a CTB16pcG3 - v5
Everything I've read and watched says I need to change the firmware to 4.20 or higher. So I went to LOR and got what was offered When I try to download it into the controller it says (Load failed, Not correct firware). The only one I can get to load is CTB16PG2-v1_06.LHX. Is this the right one?
