Job isn't finished yet. I hurried. But I asked Vitally on drive2.ru about dissassmbling of one well known product but he didn't answer.

The reason is simple why you get a 503 error, but I shall not name it, I am sure it will become apparent later on.

Try to use https://drive2.com instead. drive2.ru can have DDOS protection from unfriend contries.

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 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 vdash and сzechs) and understanding of this process. But also I want to made some benefit to community.

Interesting, how did you bypass the obfuscation? All software I used to decompile the code failed due to the protection.

.NET is not my strong suit and I have no experience in it and especially RE.

So your dilemma is to work for VDASH or not?

VDASH has two parts. One is just C# application. But they communitate with car from vdash_u.exe file which is download during VDASH UI run. No my dilemma about opening of all already found info and next which may be found to free access. Or not. Because two people who helped me make money from it.

PS Big thanks to you and another guy from this forum (he's know who is he))).
