[spirky]

Hi all
I have a big problem on a MB W203 C200 CDI.
I try to read HC912 eeprom and flash on the EZS 2095450508 W211_HC12 with xhorse Key tool plus by solder the 6 wire and hawfull, after i read it, no communication with it by CAN :( and flash reading is bad and eeprom reading is all 0000. The device corrupt both flash and eeprom !!!

I Can read and write ok this MCU with genuine XProg without any problem.

I have a spare EZS with exacly the same number and MCU.

Is there a solution to adapt the spare EZS to the car ?

Thanks for help

Yes, you can, first you need to program a new key, then reset the ECU, ESL, and bind the blocks using Star Diagnosys.
The dashboard has ssid, this also needs to be changed for everything to work.

Mcu is secured and flash corrupted after reading it's normal for this type mcu.
But , what about eeprom ?
Are you sure like your's programmer get this right ?
