Ok one of the next releases will have a "Bypass family check" or somethign in recovery. You will need to select that. Basically you flashed using a tool that shouldnt have allowed it and now my tool is tryign to prevent you doing the same (even though your going back). So a ahrd bypass on recovery will be an option with an additional verification that it can really brick you if you check it (like going from UD02 to UD04 in your case
) but it should get you back to UD02 from a UD04. So there are benefits and reasons on recovery to ignoring the family hardware check.
