Unless I misunderstand the OP, it's not that the serial number is misplaced and unknown, it is blanked out internally. You can normally see the serial number in STUDIO with a right-click>Device Properties, or from Telnet, "show system". It's coded into the ROM inside. Until something evil clears or alters it. Since software that licenses via checking the serial number finds it missing, it fails.
We just last month had a 3100 come back from AMX after a serial port repair, and the internal serial number is mysteriously now missing the first digit of the serial string. Just the one. It's gone back for more attention.

Never had it repaired and it worked fine otherwise.
