Recently brought a new DA02 for my car, got it professionally fitted to my car and all worked fine including the apps, but i then updated the firmware to 4.16 and since then, the apps have not worked since? it comes up with a parking brake message saying it needs to be on then off then on? no matter what i cannot get past that message which means i cannot use my apps? Is there anyway i can go back down to 4.14 or a older firmware? i've tried everything but i cannot find a older firmware?
