Since I see that no matter how much I ask, there are no answers, I decided to start dealing with the stupid VCDS processors (STM32F429,405,415).
It is known so far that when attempting an update, the processor is locked and cannot be read, erased, or written.
Once it has been released for an update, it is impossible to read it, and the firmware is already damaged.
The only option left is to replace the processor with a new empty one and flash working firmware. Here again, the problem arises that there is no such firmware anywhere.
So, now I will order a working adapter again and try to download the firmware, then upload it to the site so that everyone can try to repair their adapter.
It is also known that this processor is much more responsive when removed from the board and connected directly to a programmer. Popular programmers for this purpose are ST Link v2 and Jlink. Both handle these processors, the second one much better, due to a built-in option for reading locked processors.
