SDFtool Flasher

[clichekhfan]

Hey Marty, I flashed my BU4ON to MK1.03 and it still works but when I insert a UHD disk the drive icon in makemkv just never stops spinning. I also tried flashing the BU4ON 1.00 and the buffalo BU firmware and I get the same result. do you have any advice? I tried it with two different UHD disks but that is all I have at the moment. One is a retail movie, and the other is the same movie decrypted on a verbatim BDXL M-disc.

1. Clean the discs.
2. Always let the os initialise the disc first, then open MakeMKV.
3.ensure MakeMKV has internet access so it can download the hashed keys database and updates as required.

Just flashed my BP50NB40 to the BU40N 1.00 firmware, using the SDF GUI tool in Win11 with instructions provided previously. Ezpz.

Problem is, MakeMKV now reports "The program can't find any usable optical drives."

WTF?
after a power cycle, all seems to be well again. That was odd though.

It's now a full LibreDrive, yay!

Not able to download the latest SDFtool Flasher. Looks like the links are broken on the first page.

Planning to flash my drive tonight and purchase MakeMKV! Thanks much!

Links are fine. It's something on your end.

Hey Marty!

I've got a Verbatim 43888 That shows up as a Pioneer BRD-UD04. It hasn't been able to read any of the UHD disks that i've try to rip using it thus far. When I use the SDFtool Flasher to flash it to the BU40N_1.03_MK (22 Nov 2025) it gives me the "the drive you have selected does not have the correct drive platform (MT1959) and cannot be flashed" error. Not sure what to do!

Your drive is a Pioneer!! It is already UHD ready. There's no flashing it.

If it won't read UHD discs you have another issue.

1. Clean the discs

2. Always ensure you insert the disc and let the OS initialise it before opening MakeMKV.

3. Ensure the drive is getting enough consistent power. Use a USB-C port if possible, direct from the motherboard or USB 3+ ports direct from the motherboard, otherwise use an AC self-powered USB hub of at least 30w. Do not use case ports.

4. Ensure MakeMKV has internet access as it needs to be able to download the UHD hashed keys.

Try pasting MakeMKV's log window text when you attempt to rip a UHD disc.

This is your issue

Ensure that the checkbox to enable internet access is checked in MakeMKV preferences.

Something on your PC is geoblocking Russia (which is where the hashed keys are hosted). You might have to change your DNS servers and/or run MakeMKV through a VPN.

Found the issue! I had region blocking enabled for a multitude of regions in my Unifi Dream Machine, I turned it off just to test and it worked! Thank you for the help
