Repair locked VCDS STM32F405

[heshamzn]

i got working one how to read it ???

[Pfennig]

firstly, you need skills in working with a programmer, for example ST-Link V2. all details about how it works are available in Internet:

unfortunately, I don’t know how to do this, although I would really like to learn.

Anyonee who had solved it? After a few months there is no solutions still I've already bought a new STM32F405 Chipset but I haven't got proper dumps for flashing

[Pfennig]

to take a dump from firmware you need ST-Link V2 and software/utility.

SWD PINS: 3,3V, SWDIO, SWDCLK und GND (4 PINS on the top edge and the last one on the right is not soldered)

Which chip uses your VCDS cable? That's STM32F405, isn't it?

[heshamzn]

yes stm504 i got a lot of it

[Pfennig]

if you can’t just take a dump from the firmware, it means the chip is protected from reading and writing - nothing will work without special knowledge and experience. you'll just have to buy a new cable. sry (((

Chipset might be revived but it depends which level of RDP is activated. I'm convinced that is possible so it won't be easy task

[Pfennig]

the parasitic firmware, represented by the latest version of VIIPlusLoader, deliberately programmed the wrong VID&PID, now the cable in Windows is detected incorrectly, and therefore cannot be recognized... because of this, it also cannot be recognized by the flasher.

[Smart66]

That's same VCDS chipset as mine. Did you brick this VCDS cable?

this is full version on the 405th chip. updated online, cost approximately $80, plus/minus.
