Firmware downgrade using official (patched) flasher, the "Ultra hax0r guide"

[MartyMcNuts]

Brand new Asus BW-16D1HT, firmware 3.10. Internally mounted via SATA cable. Windows 10. I'm using a confirmed byte-modified 3.02 bin file "ASUS_BW-16D1HT_3.02_OFFICIAL_(BYTE_PATCHED).bin". Using Asus flasher "ASUS_ODD_FW_Changer_(Modified).exe" gives Updating Failure #4. Using the LG flasher "BH14NS40_N1.00-A4_patched.exe" gives Write DRAM NG 05/26/03. The drive works currently with regular Blu-ray disks.

Just wondering what the successful people are doing that I'm not (heh, story of my life). Thanks.

The ASUS flasher you are using is an old outdated one. Please grab the "modified ASUS flasher" from https://www.makemkv.com/forum/viewtopic ... 16&t=18933 and flash ASUS 3.10-MK first.

Well, they would read as the answer has been given quite a few times. But anyway, flash MK 3.10 first. That is NOT the same thing as what's on your drive now which is the official 3.10 and can't be downgraded. MK 3.10 will allow you to flash whatever you want.

Yep that was it - I did miss that. Lot of info here Thanks, working now.

I've just got a new drive and the details in the software say the following and no other details...

OS device name: \Device\CdRom0
Current profile: DVD-ROM
Manufacturer: MATSHITA
Product: BD-MLT UJ240AS
Revision: 1.02
Serial number: WJ66 043264

Is this drive able to be downgraded and use LibreDrive? My last drive actually told me that I could potentially use LibreDrive (but my cat then decided to jump on it and totalled it).

I thank you all in advance for any help you can give me. Thanks!
