Thanks for the info - there are many options listed on the first post. Are any better/easier than the rest?
Thanks
Prinicpially only one of all the sections is the most important: At first (really at first order) dumping your original unit's firmware.
Principially at first, you can blind out (ignore) all that text sections +its sub-steps (further down), which are NOT related to dumping firmware.
In Teddys guide: first you principially have to concentrate only on one paragraph section, related to making the original unit's firmware dump:
1) "Steps for dumping firmware : (Windows Method)"
"Download the Windows 7 Live (Portable Edition) ISO from here."
"Use Rufus and select the ISO image previously downloaded and prepare the USB stick"
{...} <=Addional rest sub-steps
----
or
2) "Steps for dumping firmware : (DOS Method)"
1. Prepare an USB FreeDOS bootable stick, using Rufus (which can be downloaded here)."
{...} <=Addional rest sub-steps 2. - 10.

Both two dumping methods share in common:
=>1) and 2) both use Dosflash (in different versions)
a) "Prepare an USB FreeDOS bootable stick, using Rufus"
b)"Be sure to connect your ASUS/LG drive alone, as SATA Primary Master (USE SATA1 or b)SATA2 controller ports)"
c)"Enable CMS in BIOS option in order to boot from the USB stick (NOT UEFI !!!!)...
d) ...and configure SATA controller as IDE !!"

So I see no advantage in "Steps for dumping firmware : (Windows Method)" over "Steps for dumping firmware : (DOS Method)"
You can decide on which paragraph 1) or 2) you want to focuse. I personally found that one the easiest:
2)"Steps for dumping firmware : (DOS Method)"
There's also 3rd Dump method Devilsclaw's, but you can ignore it: "Steps for dumping firmware : (Devilsclaw's Method only for old firmwares)"
"It is important that the dumped firmware must be the DOSFLASH dump and not the Devilsclaw's one !!
"I've written "for old firmwares" because, it seems that the latest ASUS/LG firmwares, which fixes the AACS 1.0 loophole (for UHD reading), inhibit the devilsclaw's flasher and you could not be able to have a valid dump."

Please make a copy of the original dump on several places, HDDs or USB-sticks, because if Windows reformatted/reinstalled, or if the storage device gets broken.

You can regard the other text/sections in behind later, after having original dump.
