BMW 118d CAS2 corrupt EEPROM or swap data

[goyodesanctis]

Hello everyone!!!
Let's see, I have a problem, in a friend's workshop, where this BMW 1 Series 118d, from 2006, has arrived, with, apparently, damage to the CAS.
What I have been told...


-Someone tried to manipulate the mileage with obd, I think something like FVDI, and there were also problems in the M35080, and what happens is the following.


-The vehicle starts, but through obd, it does not communicate with CAS, and I think there are more communication problems.
-The handbrake light is permanently on, I know that this was not the case, because a few months before, I myself did a stage1 on this vehicle, and everything worked perfectly.
-My friend has a lot of machinery, but, he read the CAS in bench, only the eeprom, and he still has the same error when transferring it.
The flash, which I will attach, together with the eeprom, both ORI, initially corrupted, I don't know where, and the second hand one, plus an eeprom that I have made the change of ISN, keys, 0Kms, and the key cut code, on the second hand one.


Well, once we imagine, that it is difficult to find out, what happens to the original file, do I need to synchronize ecu with cas?
And the coding?
I don't even know if that car has ELV or not, because of the synchro codes.
I am a little lost in this but I would like to help my friend to see if we can solve this problem for this client, since he has sold the car, and obviously the buyer is not very happy.
This happened by removing only 8000 kms, on the odometer, which I don't know, of all this, what was worth it.


Without further stories, which is already long, can the eeprom of the original case be repaired? or can it be seen if it is damaged? CRC for the VIN is at address 0X0409 hex, if I'm not mistaken, but I don't know if there is something damaged, what is it, and if it is complicated, with the eeprom I generated on the used CAS2, what would I need to do to start the car?
I think it has Autel IM608, if I'm not mistaken, I'm a bit lost on this in particular.

Remember, handbrake permannent light, in this case I don´t know if read M35080 too.
Thank you very much for your time!!!!
Greetings!!!
