Here is a brief chronology of the TL866CS/A Minipro. Autoelectric introduced the TL866II in February 2018 as a replacement for the 866CS/A and simultaneously ceased production of that unit. At that time (February) the software version that was shipped with those units (produced before manufacture ceased in March 2018) was Vn 6.60 or lower which is the version that came with the genuine unit I purchased in February. Any later version was only available via download from their website. It was several months later that they discovered the the 866CS/A was being extensively "cloned". Autoelectric put up the first counterfeit notice on their website which simply showed the differences between a genuine and counterfeit unit.For about six months or so, one could continue to upgrade the counterfeit units from the Autoelectric website and all you got was a "clone" message (as did RickyDean) but the unit would still work. Sometime in late 2018 probably October or November, Autoelectric decided to put an effective end to the copyright infringements. They upgraded their serial # recognition on downloads, strengthened their encryption, and posted an addition to the piracy warning on their site. The result was a warning that attempting to upgrade your 866CS/A from their website would now "brick" the unit. It could be unbricked (instructions were given on how to do so) but you were now restricted to using the software version that came on disk with your counterfeit unit - no more download upgrades. That coincided roughly with the release of Vn 6.85 in October. Of course, any unit with a manufacturer other than Autoelectric (or none at all) is obviously counterfeit.
The test will be when a new version of the software appears. If it is genuine, it will upgrade. If not, it will brick the unit. Until then, compare the case with the pictures and there other tests if you want to open the unit. I posted the pics and they are on the site as well.
