I tried flashing the backup to the bu40n mk1.03, firmware. The flash said it succeeded in the sdf tool, but then the drive shows as boot in makemkv and the sdf tool. Once it is in this state, I cannot use it to rip discs (the drive will not even open) and the sdf tool cannot flash it again, but using the LG tool I am able to reflash the original firmware, and the drive works in the sense that it can rip normal blurays, but not 4k.

Is there something I am doing wrong? I successfully flashed my old LG internal drive, but this external verbatim LG bu40n just doesn't seem to want to flash successfully.

Das gleiche Problem hatte ich auch, dass mein Laufwerk sich die Schublade ebenfalls nicht mehr öffnen ließ.
Ich konnte bei meinem Laufwerk mit der Original LG Firmware 1.05 selbst damit kein Flashen mehr durchführen, da der SVC Code nicht mehr stimmte, sehe Beitrag 8.
Welches LG Tool ist gemeint?



I had the same problem; my drive's tray wouldn't open anymore.

Even with the original LG firmware 1.05, I couldn't flash it because the SVC code was no longer valid (see post #8).

Which LG tool are you referring to?

Jetzt frage ich mir nur welche Firmware ich wirklich am besten nehmen soll, aus welchem Ordner für MakeMKV und DVDFab am besten wäre, ich vermute mal wenn das Laufwerk einen defekt aufweist und man es zurück schickt das dann eine sogenannte Original Firmware drauf ist ein Vorteil ist, also das bei MakeMKV steht - Firmware type: Original (unpatched):

Ich möchte nur einmal ein Flash durchführen und das wars, dann pack ich kein SDFtool Flasher oder sonst ein tool mit dem Laufwerk mehr an.

Und euch allen ein angenehmen Wochenstart


So, I also had no luck with the LG firmware tool, the drive went back, and now I have a new one from Verbatim, which of course has firmware version 1.05 installed.

Now I'm just wondering which firmware I should really use, and which folder would be best for MakeMKV and DVDFab. I suspect that if the drive is defective and you send it back, having the original firmware installed is an advantage, meaning that MakeMKV says - Firmware type: Original (unpatched):

I just want to perform a flash once, and that's it. I won't touch the drive with SDFtool Flasher or any other tool again.


Greetings

And have a pleasant start to the week, everyone!
