LG CD-RW CED-8080B not recording in DAO

i’ve got my very old LG CD-RW CED-8080B. i’ve got a problem with it. the thing is that i updated it to 1.08, but it didn’t want to record in DAO there, only TAO recording got well, so i downgraded it to 1.06, the previous version and hoped that everything will be alright, but i was wrong…the recorder does not want to record in DAO anymore. only TAO recording goes well.
where’s the hatch?
