4b12 d4 mivec computer data corrupted

[icono]

I have a problem with a client's car with a 4b12 d4 mivec engine.
The client took him to a mechanic and he began to program the vin with the battery almost dead and halfway through the programming the battery discharged
Now it gives an error saying that the etac does not recognize the engine computer.
I think that reloading the engine computer software can solve the problem
Does anyone have that file? Or any better idea to solve it
Thank you very much for your attention.
