CRD 2.16 E250 W207 ECM

[mekatech]

I am a technician from Thailand, I have a problem with ECM, it stopped working after reading the firmware (KESS), so I want to know if it is possible to restore this ECU using Vediamo and how to do it.

What exactly have you done?

If you have a backup, you can easily return to the original settings.
It is important to make a backup before making any changes.

Now I can’t restore the ECU firmware, and the ECU is not listed in the diagnostic report, it disappeared from the list. And make recovery impossible using KESS and other tools.

So my question is:
1. The ECU is locked, if so, how to unlock it (with what tool?)
2. Is it possible to connect Vediamo directly to the ECU pin for recovery or virgin EEPROM (outside the car)?

Sometimes after reading CRD 2 the ECU lost communication.
Post a backup copy here (Flash + EEPROM).
Use a JTAG tool such as Flex or Delphi programmer.
Then I can check what the problem is.

Here are the complete backup files using Flex.

Try to find an EEPROM dump from a similar ECU, the problem will be solved.
