Libre drive or downgrade flash?

[ESPNY]

My Asus BW-16D1HT just bricked and I got a replacement yesterday with firmware 3.10

I got a little lost about all the methods to patch it.

Does the libre drive package unlock UHD capabilities as well and what are the recommended procedures to flash and or downgrade the drive? I would prefer the easiest method. Also is there a possible scenario via USB?

Thanks for pointing me into the right direction, I have zero experience with flashing so far.

Asus Odd FW changer plus mk 3.10 flash files did the job via USB within a few minutes from win10.
