Today, 4K UHD is the standard resolution being used by movie studios the world over, especially considering that TVs and monitors that support this resolution are getting cheaper. Moreover, all of today’s common devices such as game consoles, Blu-ray players, computers, etc., are coming equipped with 4K UHD Blu-ray optical drives. That is because the standard Blu-ray optical drives do not support 4K UHD Blu-ray Discs. The LG BH16NS40 is one kind of 4K UHD Blu-ray optical drives that can either be equipped on some new computer models, or sold from participating retailers if users need to retrofit it. Unfortunately, this device can come with firmware that can render it ineffective in operations that it should take out, for example copying or ripping 4K UHD Blu-ray Discs. Therefore, we will show you how to downgrade such kind of firmware on LG BH16NS40 optical disc drives.

Part 1: Introduction to LG BH16NS40

The LG BH14NS58, referred to as a ‘Super Multi Blue Internal SATA 16x Blu-ray Disc Rewriter’ by LG is one of their UHD Blu-ray Disc optical drive for desktop computers. Its biggest and notable feature is M-DISC support, a technology that uses a patent rock-like recording surface instead of organic dye to etch data onto a disc. The result is a tougher disc that can last longer. Another notable and welcome feature is ‘Silent Play’, which helps reduce noise during playback by recognizing different multimedia and automatically adjusting the playback speed. This optical disc drive should cost you no more than $100, including free delivery in some locations.

What discs does the LG BH16NS40 support?

It supports 3-layer BDXL-R/BDXL RE discs which offer 100GB capacity, and it supports quad-layer BDXL-R discs which support 128GB storage capacity on a single disc. It also supports DVD+R, RW DVD-R, RW DVD-RAM, and standard Blu-ray Discs.

Part 2: Why we need to downgrade firmware on UHD Drive

Any UHD drive comes with its own firmware, which in some cases may impose heavy restrictions that can ‘lock’ its full potential. More specifically, UHD Blu-ray optical disc drives such as the LG BH16NS40 optical drive implement AACS2 protection. Having AACS2 protection means your disc drive needs to be presented with an AACS2 host certificate the corresponding UHD Blu-Ray Disc. At the time of writing, no such certificates are publicly available at the moment. Because of that, users cannot freely make non-decrypted full disc backups of UHD discs from such drives. In rare instances, users may also face trouble reading certain UHD media. Regular BD drives do not implement AACS2 protection, even if they read data from BDXL discs. Downgrading your LG BH14NS58 UHD drive firmware will ensure that you can read UHD Blu-ray Discs, rip them or even copy them.
