I'm pretty sure the a2 error code is a write protect error. So either 
the unlock code is not working or there is some external write-protect
circuitry getting in the way.

The mac address (depending on configuration) can be hard-coded in
RedBoot, stored in an EEPROM, or stored in FLASH. If you don't have
the command to set the MAC, most likely it is being stored in FLASH
and you'll have to sort out that problem first.
