Today, we’ll concentrate on analyzing “why Buffalo BRUHD-PU3-BK drive can not read UHD disc” and working out this problem via reliable tools.

1. Why I can’t play 4K UHD disc on Buffalo BRUHD-PU3-BK drive?

There are certain hurdles to using UHD drives (including Buffalo BRUHD-PU3-BK) since the hardware, the OS, and software requirements must be satisfied in order to use any of them to play commercial UHD Blu-ray discs.

One of the significant triggers is firmware version, some 4K drives with newly released firmware can not read or decrypt UHD disc as they need to grimly execute AACS 2.0 protection rules, inversely some old firmware version can get around this rule. In this scenario, you can flash the firmware back to the previous version that is compatible with UHD disc, bypassing AACS 2.0 execution. 2 proven yet mainstream ways to downgrade firmware of Blu-ray drive out there, one is downgrading firmware using LibreDrive patches, and the other method is bring the firmware version back to basic level via third-party program, such as Leawo UHD Drive Tool.
