BQ20Z95 smbus communication failure

Hi,

      During flashing dfi programmatically from vb code dfi became corrupt and smbus communication has stopped. Doing some search on the forum, I checked if it was stuck at rom mode but it did not respond to 0x08 or 0x0d commands. The only way to recover seems to be flashing with .senc file. But this also requires sm bus. How do you manage to flash .senc during production of bq20z95, since I guess smbus won't be functioning without firmware. Is there  tool you can share to achive this?

Thanks
