Ah, we live upside down here in Oz, we dont offend easily down under. Good to see you did the firmware update
The VIN will only be registered into the GS911 after you go into maintenance functions when using either the PC App or the Cloud Services, the basic auto scan, real time logging and read/clear fault codes are unlimited VIN functions
It sounds like you may have only loaded the WiFi utility on the PC not the PC App which has the Service Reset and other detailed maintenance functions
With the GS911 WiFi look at it as 2 tools in one, when using the WiFi interface it uses it's own internal code bolstered by Cloud Services, when you connect via USB and use the PC App it is a "dumb" pass through just like the traditional GS911 with the intelligence in the PC App
