The oft cgecks the ecu calibration id strings in roms and compares them to the original calid strings on the rom it read into itself when it was married to car. If the id strings dont match oft wont load roms into the oft
This is to stop people flashing incorrect roms to cars. like trying to load a nissan rom to an oft married to a brz.
However oft only checks 2 of fhe three calid strings, so its possible to fool the oft into loading different calids but you need too alter roms with hex editor. Not something you want to do unless you know exactly what your doing and that the rom your modifyibg is compatable with car
Auto roms dont work in manuals and some calid from newer cars are not compatable with older ones
If the rom is a brz\86 rom and its not corrupted it wont brick ecu, but if its corrupted or not from a brz\86 its possible to brick the ecu.
It should be recoverable if you have correct tools but sometimes not ann easy process
