@ MartyMcNuts

No PM reply thus far, so I guess he's too busy to check & reply. I'll sign-in every now and again for any answer, but will continue with trying it myself. Besides, working up a procedure is good experience. Thanks (and to everyone) for the help -- awesome work guys!

I have a Mac, BU50N (firmware 1.01 I believe, I don't have it with me) and around 25 4K disks. If there are any beta testing opportunities for this feature/drive support, I'd be more than happy to help. :)
Did you have to flash downgrade the firmware on your drive to get it to recognize 4K discs? I just purchased an Archgon HD 81075 drive and am wondering if I need to flash it once I get it?

If it has 1.01 or higher, then yes, you will need to flash it back to 1.00.

I'm a newb mostly. Used to burn discs a long time ago. I wanted to get back into it with UHD. I purchased a LG BU40N with firmware 1.03. It would burn blu-rays but not UHD using UHD Copy from DVD Fab. Seems mkv is the thing now so I'll have to use it once I get up and running. My problem is that I went on YouTube to figure out how to downgrade from BU40N 1.03 to 1.0 and I got tossed around from YT to mkv threads to CDRinfo.rl threads and got all confused as different people are saying different things.

I am using a Vantec USB3.0 SATA Enclosure. My PC is a laptop, Dell XPS 9350. I also have a MacBook Pro but didn't plan on using it with this drive. I read that the BU40N would need to been sidegraded before downgraded. I read I needed LG 1.04MK but couldn't find it in the MKV firmware folder. Read a comment saying "this" was it. I downloaded a firmware and finally it installed successfully. But my drive is now identifying as an LG BH16NS55 1.04. Then I tried to downgrade to BU40N 1.0 and it wouldn't work. So I downgraded to BH16NS55 1.02 which worked but still it won't go down to BU40N 1.0. The drive won't eject but does flash. It's recognized. I went back to BH16NS55 1.04. That's where I'm at. Can't figure out what to do. I've reached out an offered to pay to get it fixed remotely but I'm waiting with discs that I need to get done. Can anyone recommend anything? I've read Dos Flash only works on 32 bit and IDE mode which I don't have access to. Maybe there is some way to fix it using my MacBook Pro? Appreciate any help I could get. Thanks in advance!

Pretty sure that thread contains the firmware you need, which is also 1.03.

Just a reminder to everyone

Crossflashing Warnings:

1. Don't crossflash desktop drives to slim drives or the other way around

The only way to recover this drive now is to use the new dos flash in a dos environment
