Out of stupidity, I flashed ESP with an unsuitable 4F0 910 517 AL firmware. As a result, the car does not see ESP at all. I cannot find my native flash (4F0 910 517 AB) is there a similar car with the same ESP.
1) Is it possible to read the flash from it? How?
2) Can I replace ESP with a different number?
3) Is it really possible to find a native firmware?

SW: 4F0 910 517 AB
HW: 4F0 614 517 R
ESP 8.0 quattro H05 0040
Engine 3.0 ASB

Thanks.
