BU40N 1.00 Firmware Details
Without specific information on the BU40N device, we can only speculate on the nature and capabilities of its 1.00 firmware. However, generally speaking, a version 1.00 firmware suggests that this is the initial or first release of the firmware for the device.
Q: Can I use this firmware to play 4K discs in PowerDVD?
A: No. BU40N 1.00 firmware breaks official playback software. PowerDVD and CyberLink’s software check for the latest firmware and valid AACS certificates. If you flash to 1.00, you must use LibreDrive-enabled software (MakeMKV, VLC with libaacs, or Kodi) to play the disc directly. Most users rip the disc to MKV and then play the file via Plex or MPC-HC.
