To the best of my knowledge it is not that spoofing is not necessary but that spoofing is not possible with LT.
1.61 (or better yet 1.6NS) is a different matter. If doing it in Jungleflasher then click "open source firmware" and select the liteon firmware.
Press "open target firmware" and select your chosen firmware for the benq (1.6NS is the best firmware for an offline box).
Click "spoof source to target" in the middle of the application.
It should sort itself now leaving you to press save to file and save it to whatever you like.
The file you just made is what you flash to the replacement drive.
