Dcm 3.2 ecu swap

Hi guys, I've got a e220 cdi evo from 2007 with a bad ecu, car is towed to me, i plugged on xentry to check, but i cannot communicate with the ECU, i checked all the fuses and relays according to schematics but everything was alright.
So i taked out the ecu and bought a exactly same ecu it was already virginized so i didnt needed to bother with that at all i just plugged in the car and thats all.
But now if i want to do initial startup it did the programming, but after i only got offline scn coding beacuse off no access to online, so i don't have anything there.
I've also tried to adapt drive authorization i got it personalized but when i want to activate it says to start the engine which is cranks but doesn't start.
I've also got some pictures with faults and scn section.

Any help appreciated!
Thanks, Mate

Some pics: Dont mind about the egr and the fan, egr is plugged out and the fan is disconnected beacuse of the programming.

Faults

SCN

C270, e270, ml270,
So i've got a bit further, i flashed the eeprom from the old to the new one, i got some coding strings now,
Also in actual values-drive authorization everything is yes expect the synchronisation which is weird beacuse it has the old immo data so its should be synched right?
I attach some more pics, also the ecus numbers and what sdflash got out as "dump"

The alexmb one is what ive got the other one is the original ecu.
