Vxdiag Nano GM OpelGDS2 firmware checksum is incorrect. I will include pictures below. My guess is that VXManager is doing a 64-bit checksum but expects the result to be from a 32-bit checksum.

Problem description:

I have one concern remaining. On the Diagnostics screen in VXmanager, I select Passthru as one of MyApps and it shows a screen that says "Please install”. When I click the Install button, it says "Failed, Retry!”. It does the same thing when I try to Install the "GM GDS2/T2W”. I know thatTech2Winis working correctly because I have already used it for important work. I will have no need to use GM SPS for some time (and my belief is that is what "Passthru” is needed for) so I don’t know if it will fail later when I try to use it.

I do know that during the VxManager install it showed that it correctly installed "VCX Passthru Driver (SAE-J2534-2)” so perhaps the "Install” button in VxManager is not expected to work? I am attaching a picture of the failure screen.

Finally solved!!!
