Take your chances

Purchased waited a month to receive it, everything looked nice well packaged laptop booted up as intended however it won’t interface with any of the cat machines we have it says no ecm found. So does it work? No idea, maybe I did something wrong? The people who sell these don’t make it easy to get ahold of them.
