To understand the firmware wars, you need to understand the BDR-UD03’s schizophrenia. There are effectively two lineages of firmware for this drive: (Pioneer) and Liberated (cross-flashed). However, for years, certain manufacturers (LG, ASUS, and
If your BDR-UD03 is running an older factory firmware version (typically pre-2018 architectures), it may interact seamlessly with backup tools. If it has been updated to the latest official Pioneer firmware, the drive will strictly enforce AACS protections, preventing data extraction from 4K discs.
