I think... You haven't 8974 file dll ....
Down load it here
And then extract it and copy folder 8974 into C:\Program Files (x86)\LG Electronics\LGUP\model

Does anyone have a working link to the SEA V10d kdz or, even better a pre-rooted image?

Not sure if this is the right place to post this, if not redirect me please. I'm rocking a LG G4 h815 V20c-SEA-XX on Android M. LG's dev tool won't support unlocking my bootloader right now. Is there a work around or something else I can do to unlock the bootloader and install a custom recovery? If so can you please guide me through it or shoot me a video. Thanks in advanced!

Look into the folder "Canada D852". Those roms that have "20F" in their name are lollipop.
LGUP should have no problem flashing the above kdz, thus returning you to lollipop. From there, you then root then upgrade to MM.

You need the correct msi file. Try this: http://downloads.codefi.re/autoprime/LG/LG_G3/LGUP_8974_DLL_Ver_0_5_CODEFIRE.MSI

Hi,
I'm trying to figure out all of this. I have D852 with Fido (pretty sure I'll need the Rogers' files) on MM Stock and I want to get back to Lollipop to root and install CM12.1 ou CM13. When I go to le links provided I can't find a Lollipop file for Rogers. The ones listed are v10 so I assume those files are the Kit Kat ones. What should I do to go to Lollipop? Can I use the Telus one that is listed as it is a V20 so Lollipop?
Thanks

Hi There,
Can you point me to the procedure and the files that you choose for a Fido D852 to downgrade from MM to Lollipop and the Root method used?
Thanks
I was able to grab the kdz from the repository on http://forum.xda-developers.com/showthread.php?t=2785089 (they have one for Rogers/Fido which appears to be older but I suspect you could use it and upgrade once rooted).
Flashed it with http://downloads.codefi.re/autoprime/LG/LG_G3/LGUP_8974_DLL_Ver_0_5_CODEFIRE.MSI (as provided by gwizerd in this thread).
From there, I installed TWRP, rooted and upgraded to stock MM following Toronto Henry's instructions (http://www.torontohenry.com/2016/03/lg-g3-d852-teluskoodo-version.html) although these are more for the Koodo crowd.

If you just got stock G3, do other mods (band mod, etc) first before flashing ROM. I waste a lot of time having to revert back to factory state as I couldn't get into diag mode.

To download to lollipop I flashed a kdz from the OP's link (http://forum.xda-developers.com/showthread.php?t=2785089). Under step 1, look for the storagecow link. As Ahoroba mentioned, look in the Canada D852 folder and 20F in the name indicates lollipop.
To flash it, I needed the LGUP linked by gwizerd: http://downloads.codefi.re/autoprime/LG/LG_G3/LGUP_8974_DLL_Ver_0_5_CODEFIRE.MSI
If you are doing this to get root and then upgrade again to MM, once on lollipop follow the instructions on http://www.torontohenry.com/2016/03/lg-g3-d852-teluskoodo-version-rooting.html

H815 tot/dll
Hey
Anyone got a link to the .tot and .dll file to download. My G4 is bricked and none of the LGUP nor Flash Tool 2014 work. FT 1.8 needs the .dll and i don't have the means to extract it from the KDZ file. TIA.

Anyone tried out the "converted" F500K 7.0 to H815 kdz?

As the title says, has anyone tried out and how is it working? Found this thread on Reddit where one guy has edited the F500K 7.0 version to work with the standard H815 version..... Says the only thing not working is the GSM maybe someone has the solution to that?......
Anyways, just curious if someone had tried it out
Here is the link in case anyone is curious (in the bottom of the article) : https://www.reddit.com/r/lgg4/comme...l_nougat_70_released/?st=j5i90im1&sh=0d5e7c1c

What I did:
Download H81520o_00_0310.kdz, open it with WinHEX, change the first instance of of H815 to H816, then change the second instance of H815 to F500K, then change H816 BACK to H815. Save it, and use refurbish with LGUP
EDIT:
I can upload the modded KDZ tonight if you want to
EDIT 2:
I just remembered I changed the LGUP dll, so I'll upload that too.

EDIT: I had to temporary disable my antivirus to get it to start. The program itself starts LGUP, so make sure that you closed all LGUP instances.
If that doesnt work, try this DLL: https://mega.nz/#!b51GGDLL!n42yqpAIaEbgbx8WkoB8DtDAERx3N8tsHhPkC_XDs5M
Also, make sure you use the latest KDZ available for your device/region. I have a. H815 myself so I can't help beyond guessing.

I found rhe most recent kdz (v20g) but it gave me also the same error with both versions of LGUP dlls. I am pretty much out of ideas

You can try to use the v20o kdz to convert your device to an H815. And if that succeeds convert it back to an H818

Convert it to H815 with this KDZ:

When that's done flash a H818P KDZ. This should do the trick
