We don't take responsibility if you choose the incorrect software version for your car. But we are here to help you fix it!
When choosing a file, be sure to be the same SW / HW number as yours! Contact us If you're not sure!
We can’t take any responsibility if you write files with low-quality clone tools and writing will fail or you will have checksums problems!
You must also distinguish between different types of readouts like OBD, BDM, and Boot mode.
