There are many links there for a patched 1098 firmware
While you can't go back to an earlier version firmware for most recent LiteONs, you should be able to patch the same version (hacked or unhacked, with the same filename) on the same 5005 over and over again. Note that there is a small risk to updating the firmware for any machine.
There are two separate firmwares for each LiteON 5005, one for the processor/OS firmware (machine itself) and one for the DVDR/W drive itself. The one you are seeing on the LiteON site is most likely for the drive only because your serial number idicates that you have the latest firmware. The iLO patcher works on the on the processor/OS firmware.
LNFA1000.E30 == DVDR/W only
