An year (and more) after the release of that MP - it pops here too LOL... It's the most used MP that converts R372 to R373 with ease painless. However please note that it differs from the 42_for_all_CG7_only one, because this firmware WILL CHANGE YOUR BLUETOOTH ADDRESS. Most users might not care about that, but you need to keep that in mind. I would advise you to backup your bluetooth address seem and restore it after flash
