I acquired an old WH14NS40 drive (manufactured 2012) from a friend. It is already flashed and can do regular blurays fine. I was wondering if it was possible to flash a drive this old in order to read UHD discs? MakeMKV gives me this info about the drive:

OS device name: E:
Manufacturer: HL-DT-ST
Product: BD-RE WH14NS40
Revision: 1.00
Serial number: K89XXXXXXX
Firmware date: 2112-02-09 11:26
Bus encryption flags: 17

LibreDrive Information

Drive platform: MT1939
Firmware type: Original (unpatched)
Firmware version: 1.00

If nothing can be done that is fine I will just look for a newer drive, hopefully manufactured within the decade.

Thanks in advance

No, it cannot be flashed for UHD support, because it was manufactured 3 years before that was a "thing".

Thanks, good to know.
