Thank you for fast answer and I realy appreciate it from you...

Do I need to set the computer in safe mode or I can update the f/w when its up n running ?

I have download those files, but was a bit unsure of how to set my computer in safe mode or up n runnig as well.

No safe mode needed.

It works, now I'm able to read those 4k Ultra HD media.

Thank you very much...

Hallo again ....

Have you tested it with several 4k discs like adviced in the other topic or only with the one you had? Clean disc? No srcatches? Initialisation with Windows before openig the MakeMKV app?

Hi there no i only have one 4K UHD disk but i have ordered some more when they come i will test them and let you know thank you
i know this is off the topic but i saved my original firmware with make mkv but i need to convert it back from tar to bin can anyone on here do it for me plz thank you

Why do you want do this?

From tar to bin I don't know actually, but you can flash the original 1.00 for the BU40N which can be found in the all-you-need firmware pack.

That tgz dump is not the firmware file. It is only the important bits like the cal data. You cannot flash this to the drive.

Ok thanks for that I do understand thanks
