UHD Drive Tool

  1. What’s the purpose of the UHD Drive Tool, what can be done with it?

UHD Drive Tool is a handy GUI tool that allows users to downgrade the backup-unfriendly firmware on a 4K UHD drive, so that the drive becomes capable of backing up 4K Ultra Blu-ray discs. 

  1. What are the DVDFab version requirements?

The tool is available only in Windows DVDFab v11.0.1.x or later, running on Windows 7/8/8.1/10 x86 or x64. And note that the DVDFab platform must be the same as your system platform (DVDFab x64 is used on Windows x64, DVDFab x86 is used on Windows x86).

  1. Can it work with any UHD backup software after downgrading the firmware for my drive?

Yes, you can back up the UHD discs with any UHD backup software (like DVDFab, DVDFab Player 5, DeUHD, etc) after downgrading the firmware successfully.

  1. Do I still need to downgrade the firmware if my drive works with the backup software?

No, you don’t need re-flash the firmware if your drive works correctly already.

  1. Can I try it first before order it?

No, the new tool does not provide the trial, but it will work correctly if you follow the steps above with the supported drive.

  1. Will my UHD drive become a brick if downgrading the firmware failed?

No, don’t worry, it’s safe to downgrade the firmware. UHD Drive Tool will back up the firmware first, and it will restore to your old firmware if downgrading the new firmware should fail.

  1. What can I do if downgrading the firmware fails for my drive?

Please send email to our service team service@dvdfab.cn, and remember the UHD Drive Tool log file is required to obtain support, just attach it to the email.
