Hi I have done a search, but couldn't seem to find any info on how to update your firmware without the original.
I flashed a Hitachi 46dh for a friend a while back (last year) it works perfectly, but I would now like to update it. I have misplaced the original firmware it backed up. I would imagine I am able to read the key from this firmware that is currently on it, then dl the original firmware from somewhere, then copy over the key to that firmware, and lastly reflash the drive back. If it is possible would appreciate any help.
Thanks in advance.
