You cannot use the windows flashers to recover this drive. You must use dosflash which is on the recovery image. Download the recover iso and use rufus to write it to a USB thumbdrive.
Your PC needs to be in IDE mode (and drive connected to SATA port 0 or 1) to be able to use dosflash. No IDE mode means no drive recovery.

Even using these steps, the drive is not being recognized, most likely a complete brick, another hard-
school lesson learned-will have to get a new or used one as others are & do the downgrade steps, but CAREFULLY! Thanks.

UPDATE!!
After some diligent searching I found an eBay seller who mentioned the details of the UHD issue because it is what he specializes in, & then some!
I purchased one of this sellers' modified LGWH14NS40 burners, & as promised it works perfectly on my laptop connected by my Vantec Nextstar USB Enclosure, though I have no interest in 4K Blu Ray discs as I don't own any; salvaging my damaged regular Blu-Ray movie discs, & the ability to burn BD-RE discs on my windows, were my only intentions.
Since this new modified drive worked for me IF allowed, I am sharing the U.S. eBay seller's description with the link below the line in quotes (go to the link for described pics), to help other U.S. forum "idiots" who made the same mistake I did, resulting in an extra softbricked LG drive I now have serving as a paperweight!
I should note, that I know nothing about this seller other than what info is listed on eBay, or if the seller is/was ever affilated with this forum, but I can confirm the unit I got from this seller WORKS, & all of the downgrading work has been done for the customer, making it worth the extra investment & slightly higher price for it being an otherwise "bare drive". And if you go to the link as a logged in buyer you will see that the seller is "top rated" at 100%.

"Brand new LG WH14NS40 that came from the factory with firmware 1.03 or 1.04, depending on date of manufacture. With 1.03 or 1.04 installed, these drives are not able to read a 4K disc, developed in an effort to further the anti-piracy movement. I have changed the firmware to that of the LG WH16NS40 version 1.02, the last stable version that makes these drives capable of reading 4K discs.
This drive will function as a regular WH14NS40 would. What makes my drive special is additionally it will READ a 4K disc, guaranteed. 4K was developed around anti-piracy, so PLAYING a 4K disc on your PC has a huge list of requirements. This is only one piece of the 4K chain. I CANNOT guarantee you will be able to plug this in and play a 4K disc on your PC. It will, however, READ a 4K disc. Therefore, with additional software (NOT included in this auction), this drive can provide you options to decrypt, rip, burn, copy, etc, giving the potential to change a 4K disc to a playable file format. Additionally, "official UHD" drives now come with a firmware installed that make them incompatible with copying software. You CANNOT just go out and buy a 4K drive and start ripping files! The ONLY solution is to have a drive like this that is "UHD friendly".
Works with DeUHD, DVDFab UHD, AnyDVD HD & MakeMKV (LibreDrive enabled). Reads 3D Blu-Ray. Works with BDXL. Compatible with Windows and Mac.
Pic #2 proves the drive reads a 4K disc. It shows the LG drive set as Drive K. Note the movie title and the size of the disc at 53.9GB, regular blu rays max out at 50GB. (PLEASE NOTE, the 4K movie pictured here is NOT included in this auction!)
Pic #3 shows the hardware IDs in My Computer showing the current firmware installed, firmware 1.02.
All drives are brand new and tested for 4K compatibility after the firmware has been changed. This drive has been removed from original packaging once, hooked to my PC to change the firmware, tested by inserting a 4K disc, and back in the original packaging. Other than that, it is absolutely brand new. The optical drive is the only item included in this listing. No additional cables, software, or mounting hardware is included.
Due to the nature of this listing, I guarantee the drive not to be DOA, that it will function as a regular WH14NS40 would, and additionally read 4K discs. Otherwise no returns are accepted. All drives are carefully packed to ensure safe arrival. In the unlikely event you should receive a damaged or defective drive (again, ALL drives are tested after changing firmware), a replacement drive will be sent in it's place.
Please note although I have multiple drives in this listing they are sold individually, as each, and the price listed is for ONE (1) drive.
