Default Volvo S80 synchronization problem !!

Hello ...

-----------------------------------------------
Car ... Volvo S80
Year .. 1999
ECU .. Bosch 0261204559 .. 01275781B ... H3.2
CEM .. HW-PN 9452596
------------------------------------------------

The car doesn’t start and loose all keys and synchronization with motor ECU after battery discharge, in motor ECU fault code shown ( No communication with immobilize ).
I try to repair CEM by reading flash intel 28F400 memory and fix it, i make 2 Transponder keys by Tango , also i read internal EEPROM memory motor ECU ST95P08, i make new synchronization between (ECU <==> CEM ) success .. i install (ECU.. CEM) back to the car.

Now when i try to start the car, the engine crank and ruining for few seconds and goes off ... when i check the synchronization code at ECU i get wrong code like this (FFFFFFFFFFFFFFFFFF00) ... i do correct again the wrong synchronization code and write to eeprom back ... when i start engine, it ruining for few second then goes off again ... now i change the other ECU and ECM also i got same result ( wrong synchronization ) (FFFFFFFFFFFFFFFFFF00)

correct synchronization code 57971286433914900400
wrong synchronization code FFFFFFFFFFFFFFFFFF00

any idea to hlepe me to solve this puzzle , maybe someone can make it immo off for me >>>
