Find good flash file from same part number CAS. Write it to CAS using hexprog.

Read original eeprom, change line 0F90 (first three columns) to DA AA 55, write back.

Perform individual programming.

CAS should be alive after this.

If you have autohex you can check on it first if can solve it OBD itself. for more details please contact support. When it comes to Hextag you can check from edit option in EEPROM if CAS in programming mode or normal mode. If in programming change it to normal and write eeprom back. Also you need to change Flash
