Downgrade UHD Unfriendly Firmware for Normal Backup

The existing firmware inside 4K UHD drive (also called 4K Blu-ray drive), either 4K Blu-ray internal drive or external 4K Blu-ray drive, might be unfriendly for reading UHD disc data and further copying UHD discs to hard drive or onto computer, or ripping UHD disc to digital formats for playback on multiple devices. Here comes a firmware downgrading tool, Passkey UHD Drive Tool, which is designed to help you downgrade the current firmware on your 4K UHD drive, so that you can make legal backups of your 4K Blu-ray discs with 4K UHD backup tools, such as UHD Copy and UHD Ripper.

Support All Types of 4K Blu-ray Drive and USB Drives

As an UHD drive tool, it is fully compatible with almost all UHD drives on the market, including 4K Blu-ray internal drive with SATA interface, and external 4K Blu-ray drive or USB drives. In addition, whether your UHD drive is using AHCI or IDE interface, both are supported to be downgraded.

Truly ‘One-Click’ Mode Made it Easy for Everyone

This handy firmware flash utility is easy-to-use with intuitive interface. No profound knowledge or special skill is required to perform the downgrading process, whether for novices or experienced users. Whatever kinds of 4K Blu-ray optical drive you have, all you need to do is start up the interface and click one button to finish the downgrading process.
