First of all I want to thank everyone who is a part of makemkv and the great members of this forum. I bought myself an ASUS BW-16D1HT a few months ago to rip all my discs. I already ripped about 200 discs, but sometimes there are read errors when ripping UHD discs (~20%). So I thought it might be smart to get a second drive to make sure the read errors are not the drives fault. I bought a second ASUS BW-16D1HT. The seller said it was "untested", but I think I was just too naive . I installed the drive a few minutes ago and it was recognized by windows and makemkv. The makemkv information is the same except for the serial number. The previous owner must have installed the 3.10 MK firmware.
The drive tray works without a problem, but as soon as the drive closes makemkv says "No Disc". The drive does not even try to read the disc unfortunately.

Any ideas what could be wrong with the drive?

What's the build date on the drive

24.11.2014

Yeah they bricked it with the wrong firmware the drive needs to be 2015+

Is it possible to downgrade the firmware again?

Is it "no disk" for ALL disks, or just UHD?

I tried all sorts of discs and none of them made the drive even spin up. "No disc" everytime.

It's possible to recover look at the uhd guide and watch the old video labeled usefull for recovery and use Marty's boot image the one I linked is no longer up

Which firmware version should I flash? Are the 3.X versions even compatible with 2014 drives?

no 3.x you need asus 1.x
marty has it in his boot image

I followed the instructions but it does not work for me. DosFlash always reports "MTK Vendor Intro failed!". I am still not sure which firmware to use anyway. The oldest firmware included for the BW-16D1HT is version 3.02. Am I supposed to use one of the older LG NS40 firmwares? Version 1.01 to 1.03 for the BH16NS40 and version 1.01 & 1.02 are included for the WH16NS40.

ok yeah this is a bit more complicated since it has 3.10 firmware that disables dos flash first you will need to flash a FW that supports dos flash like 3.02 with the regular flashers lg or asus then shutdown the pc dont reboot the drive must lose power fully or you will get the mtk intro fail again some pcs you may even need to flip switch or pull plug and drain caps with power button. once you do that reboot and try again it should now show up in dos flash and just follow my video after that

also yeah if it does not have the asus 1.x fw the lg ns 40 fw will work fine

It worked flawlessly this time. I just ripped a Blu Ray without any problems. Thanks a lot for your help
Another BluRay drive is not really what I was looking for, but atleast the drive works again

Charge the seller for the repair and we can split the profit lol

eBay - for parts or not working - "untested" - bank transfer

It was basically my fault for being too naive. He sold a lot of other drives which were tested and working...
So why should he not test this drive aswell? I guess the answer to that question ist quite obvious
