Eep part is A2129028102 , flash size must by 384 Kb .

Not sure about your flash size because it's 256 Kb and for me that's is wrong .

You need programmer to write flash. it can be xprog or some like this. EEP you can write with FVDI

For what this playing , like eeprom obd and flash bdm.
If eep stay in boot and flash corrupted , in here noting to do any more with obd2.

For put to work cgw to normal mode all job only bdm .
If not , so.......my option better don't touch any more this car if you don't want anderstand programming world.
