    You simply can't. The EEPROM parameters masked by 00 are overwritten as soon, as you change the value there to something else. Reflashing to another version would not help, as this does not affect this specific part of the EEPROM.

    The simple rule is that if byte 18 is 00 then modifying byte 18 is a seriously bad idea - because you don't know what the hidden code is, which means you can't go back to it.
