How to Downgrade Unfriendly Firmware Based on Supported Drive List

As 4K Ultra HD Blu-ray grows in popularity, many movie collectors and home theater enthusiasts want to back up their high-value discs. However, not all Blu-ray drives can read or copy UHD Blu-ray discs due to strict security and hardware limitations. Understanding the difference between "4K friendly drives" and "unfriendly drives", and learning how to convert your drive to a compatible state, can make copying and enjoying your 4K movies much easier.

Before creating UHD backups or modifying your drive, it's essential to consider both legal requirements and everyday risks. Here are key points to keep in mind for safe and responsible use.

1. What are 4K Friendly Drives?

4K-friendly drives refer to regular Blu-ray drives that can read BDXL media but do not implement AACS2 protection. Though unable to be used with official software, such 4K UHD drives allow any software with a regular AACS1 host certificate to read UHD data on the disc. That means the UHD Blu-ray drives are not specifically designed to work with UHD Blu-rays, but DVDFab backup programs can work well with such UHD discs.

2. Why Downgrade 4K Unfriendly Drives?

Since the current market is flooded with countless so-called '4K friendly drives', there might be times when you encounter 4K unfriendly drives whose firmware fails to work compatibly with DVDFab UHD backup software like UHD Copy and UHD Ripper, thus preventing the backup software from reading data on 4K UHD discs and further copying or ripping UHD content.

Firmware is the internal software that tells your drive how to behave. "Downgrading" means replacing the current version with an older, backup-friendly firmware.
