!PAID SERVICE/HELP" Mercedes G500L, EZS problem

[DeLuXe]

Hi,

I read MCU2 (mcu2.bin) with start address 0000 and size 00FF.
I compared the mcu2.bin and MCU2_First_Read.bin (first time read but not as 0000 and 00FF).
They are almost identical.

Is it possible to see if the files are corrupt some how (I believe there is a hash error)?
I have bought a used EZS but wich is same part number.
My idea is to replace the original chips to the new donor EZS from scrapyard.
Should I read both MCU1 + MCU2 from start address ~0000 and ~00FF ?

Before that I want to check if the files in the both IC's are ok.
I know the EEPROM is ok because MBTool accept the EEPROM file so one of the IC's is ok and that is a relief.

Thanks for all the help.
I can pay for the help of making this car start again.

Car + EZS info and Car problem brief:
Before all this, the car had a Keyless Go card wich the car start with. I toke out the EZS to program 2 new keys.
After that the car only start iginition with keyless go card and when placing the new key in, it shuts off the iginition and doesnt turn.
I would even pay just to make the car start again even if it was only with the Keyless Go card.

EZS Part number: A2205450008
MCU1 + MCU2: 1D69J
Car: Mercedes-Benz G 500 L, 2001 year model


Best regards,
