Gents,
that thing drives me nuts. When going to 4.4 needed to read a certain Ford model the firmware upgrade happened and succeeded but i am now stuck with inoperable MPV1. It does not work with 4.4, randomly works when going back to 4.3 and absolutely will not work with 2.24
it is a MUST HAVE item to go back to older firmware as i MUST be able to use 2.24 for certain abroad customer which i have to support remotely.
is there a way beside buying a used MPV1 to go back to old firmware which worked just great, i have hundreds of credits on that thing
