VAG-COM/VCDS EVERYTHING

[liviudiaconu]

Where i'm wrong?
Installed last V II loader, 20.08.13.
Launch loader, say update, updated. But not offer me version of VCDS choose (Offered me long time ago, only one time) and when i drag and drop VCDS.exe from ROJ lang try to launch and "Software startul failure".
With any old version is the same. Cables are with 405.
In VCDS 20.12.0 EN work well
Tried to uninstall loader and reinstall but nothing.
How can determine loader to offer me the choose vcds version?
The same on W7 64 and W10 64

drag your vcds desktop icon onto the loader surface on your desktop ( when the loader is active ) , and it will start that version .

Cable works fine without Loader, but only 20.4.1-EN wersion.
I try use 20.12-EN with this cable but Kolimer loader not work (hangs) and VIIPlus loader says Illegal cable.
It is possible at all ?

Hi
I am atm trying to make my own tool to communicate with the cable to make thinks a bit more easy.
The first stage of the communication is to agree on a 256 bits AES key to use for the rest of the session.
This key (there are in fact 19 of the) was also changed from my 415 / 405 cable to the upgradable one so I needed help from a forum member to extract this info.
But the best way would be to make the tool support this and there is one more function I need to reverse to complete this task.
Since I am working with the loader and have the key it's not to important and I wont spend time on this algo atm but if anyone else want to join in and helt that would be great.

So the cable sends 0x80 (128 byte 1024bit) to vcds.exe and this data is now decrypted/encrypted (depends how you look at it) using RSA1024. The 256bits' AES key is now derived from this data by calling a function that will return this AES key. I need someone to have a look at this function and figure out how this is done.

Use the unpacked version of vcds (20.12) and thanks to whom ever unpacked this exe coz this helped speed things up
At address 0x4B56DC is the function that will extract the AES key from RSA-C
In this function there is a call to RSA decrypt
0x004B5736 call rsa_decrypt(rsa_c, len, v11, &rsa_ses, 0, a7);
and the decrypted rsa data (rsa-m) will be returned in "rsa_res"
below this then this function is called
0x004B575E call sub_4B5377(v11, rsa_ses, a6, aes_key, a5, key)
and uses the decrypted rsa data and derived the aes key from it.

If someone could have a look at this function then that would be great..

Exactly this i made and i obtain an error message: Software startup failure. No metter the version of loader or the version of ROJ soft.

In the past i has an ARM cable working in SVO language. Tested here, loader offered me the soft i want, and worked. From that momment not another regional soft working on an ARM cable. And loader not offer me that option for choose which version want. No metter if is new or old. The same error.

Tried to uninstall loader..used CCleaner for elliminate garbage, nothing.

I will give you the VCDS Hex-V2 with main chip STM32F405VGT6 factory and manufacturer the technical support engineer contact mode

No, STM32F415 inside

STM32F415 doesn't support upgrade, only STM32F405...

To resume :

ATMEGA162 based cable -> Kolimer Loader
STM32F405 based cable -> VII Plus Loader

STM32F415 -> doesn't support upgrade

Hope it help...

STM32F415 is not enough good. there are many bugs. but we need the best tool to earn money。

[flyfvdi]

STM32F405 + VII Plus Loader is the best vcds hex-v2. support update and multi-languages.

[Bastard2]

I have an atmega162 based V2 cable flashed and currently working fine with v19.6 and kolimer's launcher.

What's the latest reliable version I can upgrade to?
