Usually PROTECT means "that the output amp is faulty".
But in these units (CDR23, CDR24) it is related to the MOST-Bus system. The unit is married to the car via this system. Like "SECURE" message on Nissan ones.
I don't think you will find a free PROTECT-free dump online.

PROTECT normally denotes that the output amp is faulty---- why do you think it is a dump eeprom fault.
