I purchased the MD802 last year. I finally decided to update it today. After using the update tool, my scan tool no longer works! If I take the memory card out then plug in my scan tool, it just tells me to insert the memory card. I safely removed the memory card from the PC after updating it, and plugged it into my scan tool. I then connected it to the OBD2 port on my car, and the scan tool doesn't boot up at all, the screen stays black. I uninstalled all the updates that I did today, but that didn't work at all.
By the looks of it, the scanner itself is ok, but the memory card and the software isn't. Is there any way to reset it back to factory settings? If I throw in a new blank memory card, perform the update on that, and then throw that into the scan tool, would that work?
