I just purchased the 129 and I am trying to update the software and I am getting the "download failed" error when I try to update the card files. I was able to perform a restore and then it worked in the scanner but I cannot update the files for firmware. Also, I purchased it so I can scan SRS codes and it will not connect to the SRS system on a 2007 Hyundai Sonata with a 3.3L. PLEASE HELP!
I had same problem with update. Now I just click on just a few updates I need and it has been working OK.
Did you try scanning the SRS with just key on engine off? I know that I cannot scan Honda SRS with it running for some reason. But I can scan it with KOEO.
You can always contact tech support also. I've already contacted Launch many times. I have told them about GM incorrect sensor data and the guy told me that new GM update is coming soon.
support@launchtechusa.com is a good way to contact them.
