Possible To Recover LG 8240B/BadFlash?

Unfortunately I got back the RMAed LG 24x RW last week. Tried to update to newest firmware, but got bad flash.

I have looked over @ the other threads about this topic, i.e., taking just the PCB and flash it. I tried but didn’t work.

Anybody can shed some light? I am hoping I can sneak this drive for another RMA. The BIOS of the drive is integrated with the main OAK controller (told by an LG tech).

Thanks in advance.
