BU40N Revisions

[Laithan]

Hi all, I have been searching a lot and reading the ultimate guide but I cannot seem to find any definitive answer regarding the various revisions of the BU40N UHD drive. Is the answer that they all just work? There is an HP version, I think there may be a Dell version, some have the UHD silkscreen on the front, some do not... and there seems to be a bunch of revisions such as AFIK100,AFUK1N0,PVM4X and more. eBay prices show that the model with the UHD logo costs more vs one without the UHD logo.

From the guide:
1. Make sure your Drive was built after 2016 on label or late 2015 if you want to risk it.
2. Drive Platform MT1959<Most important in makemkv
3. SVC NS50+ LG only on label for NB drives NB50+
4. Just because your drive is the same model number does not mean it will work, if you are unsure ask me i offer remote flashing and check everything before i flash.
5. Dont flash your dive if it does not meet these requirements if you do you will be unable to read all disks and unable to restore without dosflash that does not work on most modern computers

I don't really understand #3.. I don't see SVC NS50+ on any of the labels that I look at.

To make this question easy I guess, is there any revision of the BU40N that is not UHD friendly? Is there any revision of the BU40N that I should avoid? Are they really all the same besides the stock firmware they ship with? Any clarification would be greatly appreciated. Thanks in advance.

Most or all BU40Ns should be fine.
But there was another post here a few days ago about a bp50 and it looks like they are changing stuff so BU40Ns could be changing for now get one with a build date between 2016-2023
We will see in the coming months
