Just so I can categorise the issue correctly, is this an issue with the flash, with the flashed 1.03 firmware, with the original 1.05 firmware or something else inside the drive? The firmware which you flashed to your drive is cryptographically signed. If there was any corruption with the firmware ...

So I can fix it by unplugging and replugging it (which is what power-cycling is, as I understand?) Yes, that is correct (B)ut how did it happen in the first place, might it happen again, and how do I make sure it doesn't? It can be caused by a number of things: bugs in the stock firmware, limitatio...

No. It appears your drive has been revoked. Did you flash it? Post your drive and libredrive info sections. After a drive has been flashed with a LibreDrive compatible firmware AACS certificate revocation is largely irrelevant from MakeMKV's perspective. Can't read AACS VID from disc The fact that ...

No. It appears your drive has been revoked. Did you flash it? Post your drive and libredrive info sections. Yes, like I said, a couple discs worked, then none worked anymore, even the ones that used to work. I re-flashed it, even though the firmware was already the same I was flashing it with, and ...

Weird, a couple UHD discs worked, but I'm getting the same error message again: ... Error 'Scsi error - ILLEGAL REQUEST:COPY PROTECTION KEY EXCHANGE FAILURE - KEY NOT ESTABLISHED' occurred while issuing SCSI command AD010..080002400 to device 'IoKit:/IOBDServices/D48F36DD' Can't read AACS VID from ...

ah, ok. there's no side-grade. You are using the same model firmware at all times. Yes, use firmware BU40N 1.03-MK from the MK/old folder and make sure you have rawflash enc in your command. Once the drive has been flashed and shows as firmware BU40N 1.03 you are done and can start using it to rip ...

What?!? Your Verbatim should be a BU40N drive with 1.05 on it. There's no trick to flashing it. Just use SDFTool flasher and flash it directly to BU40N 1.03-MK (we call all firmware in the pack "MK" as it's far easier than NM000343.....) first, which will remove the firmware encryption an...

The firmware has absolutley nothing at all to do with the AACS version of the drive. When you insert a BD disc that has a higher AACS revision (happens on some new releases), it will automatically update the drive's revocation lists and you will notice the highest AACS version change to that of the...

It's in the MK/old folder in the firmware pack. Oh yeah, that's right, thanks! Can I use it safely to flash the drive though? What's the significance in the AACS-version difference?
