I just updated my VCDs to 15.7.0 and received a message to update the firmware from 1.93 to 1.94. I tried and received an error message of unable to update. Now I can't scan any of my cars.

Please help.

Are you using a real windows PC, or a mac with emulated environment?

How old, how new? Does it by chance have a USB 3.0 port? If so, does it also have USB 2.0 ports? If so, please try a USB 2.0 port. Or please try a different PC.

Also what brand/model/speed/OS is your PC? Do you have the interface connected directly to the car and PC while you are trying the update? If you are using an extension cable, try removing it from the equation.

I've been using this PC for 3 years with no problems reading the ECU from several different VWs. Only after I updated version 15.7.0 of VCDS did I start to have problems. I have a Samsung laptop model NP-R540 which runs on real Windows 7.

When I tried the update the hex it was connected to my PC via the USB but not to the car as the instructions said not to connect it to the car.

Please double check the instructions. They say it MUST remain connected to a car. If you unplug from the car, it won't work.

Beg, borrow, or steal another computer to try?

Edit: Just to do the update, I mean. We've seen a number of cases where firmware won't update on persnickety computers, but VCDS otherwise works just fine on those same machines. Since your interface was shipped this spring, I doubt you've had to do a firmware update previously, right?

Are all your system drivers from Sony up-to-date?

If your laptop crashes, it really sounds like there are issues with the drivers that Sony provides for USB3...
