This morning a customer contacted me because his Techstream software for MVCI Toyota prompted “unable to connect VIM”.
“I installed from both the supplied disk and the Skydrive, also tried all the different installation instructions on my Dell laptop. No problem installing Techstream. But when I applied it to a 1999 Toyota Yaris, I got the error: unable to connect to VIM.”
I also flashed my 'original' x-horse mvci with this file and now also useless. My MVCI is bricked. MVCI No brick you must change the serial number of the firmware file to that of your own,(what you see inside the update software), then upload the firmware Still no luck:/ I successfully update my MVCI from X-Horse to last firmware. Yes, Firmware its 2.0.1, I did update,but after that MVCI its not working with Techstream or Vida. Mvci Xhorse 100% original. I donwgrade it to firmware 1.4.8 but now useless, same thing not connect. I will return it to factory. A:Xhorse MINI VCI Toyota firmware version: V2.0.4,but copy MINI VCI is V1.4.0 if you want to reset immo, or make customization to cars, need at least 2.0.1 Firmware version. So with 2.0.1 FW there is change in PCB, as it support VPW, and has extra security chip.
He provide two pictures of the error message and the software interface:
The tool he bought is an original Xhorse MVCI diagnostic tool. It is highly recommended by professional Toyota mechanics. Usually the reason that the error pops up is not with the tool. So I inquired the customer and found out that he run both the Techstream and Xhorse firmware at the same time.
If you own a MVCI and are reading this article, please be aware that do not use Techstream when the firmware is in use; vice versa.
This is because the softwares will both communicate with MVCI 3 in 1hardware, and interrupt Techstream working. Here is the solution to the problem:
Solution 1:
Restart laptop.
open Techsream, click “Setup”, then “Techstream conficuration”.
2. Select “Area Selection”, get a country list and then select “Europe”.
3. Select “Default Language Selection” and choose “English”.4. Click “Ok” in the next window.
Solution 2:
Install MVCI 3 in 1 software and drive on a desktop with Windows XP system.

Run Techstream separately.
Sometimes it could be with the laptop that Techstream is installed on. If the software works, it means the laptop does not support the software.
