Product Description

• Made from the latest available official firmware.
• Re-enabled vendor commands to update microcode in memory.
• Re-enabled ability to read UHD discs (if drive was capable, and disabled in firmware).
• Removed firmware downgrade check (if present in firmware).
• Removed firmware "encrypted" downgrade check (if present in firmware).
• No other changes.

Specifically, MK patch does not meddle with AACS code in firmware and contains no bugfixes, or workarounds or other changes of any sort. For example, if official firmware image does not allow reading AACS2 metadata with AACS1 host certificates (so-called "friendly drive"), MK patch would not change that. For BDXL compatible drives MK patch would re-enable ability to read UHD discs, but it would not fix the "sleep" bug, or any other firmware bugs. All MK patch does - it makes the drive LibreDrive-compatible, nothing more.
Each unit was tested and validated to be UHD Friendly.
Be able to RIP UHD Blu-Rays with appropriate software.
