SCN via Vediamo

Hello everyone! I’m new with vediamo and I have some questions. I’ll be glad if someone can help me.

So… the problem is that I’m trying to code open trunk with key on W218. I don’t have the option on this software so I flash a new one for this model (2189023301). The problem is when I flash the CFF the button in the trunk are not working anymore. So the main question is what should I change so everything works. I’ve save the old variant coding and the strings are all same.

This is my old SW - 2184420019 and my
HW - 2123200426

For start, flash original SW back

I did it but it’s still the same problem. Buttons doesn’t work.

That's good as it means that you forgot to save a mandatory file.

Thanks!
