Did you make backup of CAS eeprom & flash? If so, write them back and CAS will be back to original state.

If not, read CAS eeprom and flash and post both files & cas part number, maybe someone can fix.

hello
You can try to do cas firmware multiple times, if error keep on coming then try to do indiv programming. If you get error on indiv programming also then that means your CAS is in programming mode. You can just read eeprom from CAS and check if its in programming mode or normal mode. If in programming change to normal mode then save and write eeprom back. Read again to confirm the changes.
Also you can write the attached flash to cas then do cas firmware in autohex it will work.
