Flashing Checksum Err BU40n
I've read a lot of threads and guides and still having issues. First post, sorry if in wrong place.
I started here https://www.swedetrap.com/how-to-rip-4k ... ray-discs/ and bought same drive. From posts on this board it seems to be a popular one. I am using Windows 10 and have it plugged in to a usb-c port.

Re: Flashing Checksum Err BU40n
I think I went down this path partially before and then stumbled.
I didn't find a direct match for: "BU40N 1.03MK"
I found two so far
1) HL-DT-ST-BD-RE_BU40N-1.04-NM00500-212005061142.bin in the Mk-firmware-pack
2) HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934 which is from the "All you need firmware pack"?
Do I use one of those?
Thanks for the help!

Re: Flashing Checksum Err BU40n
Thank-you that worked.
I was able to use MakeMKV now on an UHD disks. I also paid for the copy of MakeMKV.
Does anyone know if there is a ROM that is safe to flash to this drive to make it AnyDVD friendly as well?

Re: Flashing Checksum Err BU40n
No, there isn't one. Slim drives cannot be made "friendly" for AnyDVD usage.
Cheers

Re: Flashing Checksum Err BU40n
Ok thanks! I can now rip mkv files for our NAS from our UHD disks so I am happy with that!
I really appreciate the help and the great software

Re: Flashing Checksum Err BU40n
Hi,
I made a mistake.
I flash my BU40N Lg Drive directly to the 1.04 original firmware.
I need to flash it with the HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin firmware or with the HL-DT-ST-BD-RE_BU40N-1.04-NM00500-212005061142.bin firmware.
I get the same message :
"ChekSum is mismatched.
Drive will go to boot mode
Please retry again."
I didn't manage to flash it with downgrade tool (Both with Friendly Firmware Pack and Downgrade Enabled Firmware V.2)
I didn't understand clearly if it is finally possible or not.
Can you please make me see the light ?
Cheers.

Re: Flashing Checksum Err BU40n
What does "enc" mean ?
Re: Flashing Checksum Err BU40n
"enc" is for "encrypted", all right.
But what do I do ?
I have to use SDF tool ?

Re: Flashing Checksum Err BU40n
Allright,
I follow the tutorial under "How to flash[...] and commands", at viewtopic.php?f=16&t=19634#p74718, recommanded here.
I copied the firmware to the c: root, open cmd in "execute" (not Powershell) and write :
"cd C:\Program Files (x86)\MakeMKV
makemkvcon64.exe f --all-yes -d E: rawflash enc -i C:\HL-DT-ST-BD-RE_BU40N-1.04-NM00500-212005061142.bin"
where "E:" is MY path drive (be careful).
And it flashed !
Thank you very much, guys, and see you.

Re: Flashing Checksum Err BU40n

Re: Flashing Checksum Err BU40n
Are you perhaps starting from an encrypted FW & NOT using the 'enc' switch?
Paraphrased from above:
- Remove disc in optical drive, if any.
- Copy HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin to c:\
- Open 'Command Prompt" (not Powershell) and (assuming your drive letter is E:) execute:
cd C:\Program Files (x86)\MakeMKV
makemkvcon64.exe f --all-yes -d E: rawflash enc -i C:\HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin
