18x is impossible for any UHD device.

Successfully backupped The Martian EXT. UHD with ASUS BW-16D1HT 3.00 firmware (maximum ripping speed 7.5x) and no errors at all.

I'm ripping same uhd disc you have on my system.

Now I'm using BH16NS55 flashed as ASUS BW-16D1HT 3.00 firmware and MakeMKV 1.12.0 with latest hashed keyfile.

Hold on, I'm going to try another firmware.

Oh nooo, dropped Read Rate from 24 K/s to 0.8 K/s...at about 50% :shock: :shock: Sometimes it does the same to me, but you have to let it go and after 1-2 mins it will start to increase speed again. Anyway I'm doing some tests with other firmwares, if I find the best for you, I'll keep you updated.

Fingers crossed.

I've sent you a valid dump (3.02 ASUS based) which should fix your MakeMKV issues.

That error is due to AACS 2.0 specs being a Real UHD drive.

Anyway if a hashed key for your disc is known (i.e. inside the hashed_keys.txt file) your UHD disc will be decrypted anyway.

Hi guys, I've found a way to properly convert a UHD Friendly drive, into a UHD real one and viceversa. In order to do it, a proper firmware dump of your unit is needed and to do that, you can follow my guide linked HERE !! List of UHD Friendly drives supported : ASUS BC-12D2HT ASUS BW-16D1HT LG BH16...

You can use the devilclaw's flasher (under windows command prompt) to dumping faster (if it works).

If you send me valid dump (from both devices) I can see what's going wrong.

I can try to fix your BH16NS55 if you wish.

Try to follow my guide to create a valid firmware dump of the faulty BH16NS55.

If a VUK for your version is unknown, you have to send first the generated dump to Mike in order to have the VUK added in the keys_hashed.txt file.

Then you will be able to properly decrypt either original disc or protected iso.

I don't know if it's normal. Anyway I've sent you a valid 3.02 dump according to your data.

I definitely welcome being able to flash my LG BU50N to be able to rip discs. That would be awesome. I have been waiting for some ability, software or firmware to make it possible. Could you please dump your BU50N firmware please and send it to me ? You can use the Devilsclaw's method linked in my ...
