Can you send me vdash_u.exe?

Addendum: Thanks prometey for IDB. x86 is where I shine at, I have to use good ol' Olly or x64dbg.

Ok. VDASH software has protocols and some SBLs inside their communication layer. This layer downloads during car communication. So it can be dissasembled and reversed for protocols not only Volcano which is known but also for UDS and newer. The code of vdash_u.exe is very alful. For example 8000 lines of code inside the main function is very funny. Also many copy-pasting about sending data to j2534 channel and reading of messages in place instead of HAL layer. So from developers point of view Pavel (vdash developer) is junior developer. But he is very enthusiast of Volvo. Eight year ago I tryed to dissabled vdash code. And there was an message from him about russian hackers that we assholes on something like this. But he is russian too. In current vdash code only message with job offer. So I have a dilemma. I don't want to ruin all the work of all the people who helped me with Volvo flashing (not the fucking vdash and fucking сzechs) and understanding of this process. But also I want to made some benefit to community.

Is this pavel the same one who has something to do with orange 5 calculators and scripts?

I don't know(

I identify Pavel by this comment:

He is unnamed now but Olaf answered to him by Pavel.

Also his nickname is ok2ucx
Empty github page https://github.com/ok2ucx
Looks like he uses github as place for private repos.

I wonder if he is the dev that has somthing to do with the cem synchro software that isn't available anymore...

[prometey1982]

I have some CEM synchro software for prefacelit p2 and p1 cars.

I have some CEM synchro software for prefacelit p2 and p1 cars.

There quite easy to find via aliexspress ( although hacked by someone) , I was more curious to how to disessemble the software and see how it works. , as its not being developed anymore , and there are still quite afew varaints they do not cover , i wanted port it over to other programming devices such as orange 5 , iprog , upa etc

[prometey1982]

I want to implement programming and logging over ELM327 hardware. Need to extract HAL in my software.
