For flashing, a LG drive should meet all of the below:

Manufacture date 2016+
Drive platform MT1959
SVC: EB50, NB10, NB12, NB50, NB52, NS50, NS55, NS60 (not sure if there is an EB52 or not but if there is it shold be ok)

Basically, if a drive meets the first 2 but has SVC: EB40, NB40, NS40 forget about flashing it. It's not worth the risk, as you found out...

SVC EB52 works with flashing
Source: trust me bro (posted my drive details above and am happy to provide more info if anyone needs)

I hope it's OK that I continue on this tread

I have a BP55EB40 drive too (It's a HL-DT-ST BD-RE BP55EB40 to be exact) with 'SVC Code EB52' on the box I've flashed it with the firmware for this drive. All OK. I can rip Blu-rays with no issues. But when I try to load a 4K disc it spins for a minute and then MakeMKV says "No disc inserted"
The drive supports BD-XL

Can I do anything to make it work?

You need to cross-flash it now. Use the RECOVER method of SDFtool Flasher. See the section for BP50NB40 SVC: NB52 and the gif in the SDFtool Flasher thread.

Can you provide the exact and correct step-by-step flashing procedure for an LG drive BP55EB40 SVC Code EB52? The information is somewhat scattered across the forum, and it’s hard to figure out what exactly needs to be done.

Thank you in advance.

See guide below or Marty guide both ways work
I would say if your not on windows my way would be easier other wise the same

If you are on Linux, see here viewtopic.php?f=3&t=40977

Otherwise use the GUI tool on windows, it is easier to use than commands. But the individual flashing steps by themselves are identical

Read - Think - Understand - Think - Do it right.
That's a tough process but I succeded.
Now I'm working my way through the 4Ks that my Asus drive couldn't read

viewtopic.php?f=16&t=22896&hilit=SDFtool+Flasher

My workthrough
- first I flashed my drive with the BP50NB40 (NB50) 1.03-MK firmware. I'm not sure if that was necessary at all. Because it didn't effectively changed anything
- Then I flashed with the 'DE_LG_BU40N_1.00.bin' from the zip-file from the link above. Now It works perfect.

Hi,

I have the exact same drive as you. I also flashed both firmwares one after the other. Unfortunately, I still have the same problem with UHD movies as you did at the beginning. Does anyone have any idea what I'm doing wrong? Here is the information from Make MKV:

You have only done the first part. You now need to do the cross-flash by means of the RECOVER step. In the SDFtool Flasher thread, read the section on BP50NB40 SVC NB52 and follow the steps / gif from the RECOVER part.

Thanks. After reading it three times, I finally got it . It worked right away.

I have a question crossflashing LG BP55EB40 SVC EB40 for UHD compatibility.

If I understand right, this post says no: viewtopic.php?p=194641#p194641

You have an SVC: EB40 which should never have been flashed. It is not UHD compatible. Please stop flashing it. It should at least work as it did before. There is very little difference (if any) between the BP55EB40 and the BP50NB40.

and this post says yes: viewtopic.php?p=181611&sid=fcdef59e5173 ... 8f#p181611

Go to the SDFtool Flasher thread and read the section on SVC NB52, even though your's is SVC EB40

So does crossflashing work or not?

Thanks!

Check the date of the firmware. Only drives with firmware after late 2015 can be flashed for UHD.

Does that mean, if the BP55EB40 has SVC EB40 and has firmware after late 2015, it can be crossflashed for UHD compatiblity, otherwise not. Right?

Thanks!

Post your Makemkv info and hope for Marty's answer. He is the authority.
