LG G3 Endless Bootloop Logo->Firmware Update->Restart

Hey guys,
I really hope someone will be able to help me out.
I will try and provide as much information as possible.
I own an D855 bought from Germany. The phone originally came with the stock rom 4.4 I believe. I had rooted the phone using purple drake. few days ago I update the phone to 5.0 Lollipop, the official version rolled out by LG.
I lost the root after update and didn't re-root. Today during work my phone had gone into a boot loop (Logo->restart->logo-Restart). I though "okay that's fine , when I get home I'll look into the unbrick methods and fix this easily" Wrong.
I tried using the instructions provided by the user zedomax on youtu "How to Unroot/Unbrick LG G3!"
Downloaded all the drivers and the LG g3 Flash tool. Also downloaded a European stock rom. I got to around the 6:35 mark on the video, removed the cable and replugged it. Then the phone just shutdown and started a boot loop again. The boot loop had now changed to Logo->Firmware update page->restart->logo->firmware update page->restart.
Now I can't put the phone into firmware update mode anymore and I am really scared the phone is hard bricked. What is the next thing I can try?

I am offering a 60€ bounty to whoever has a fix for this.
I can also try taking a video of the boot loop if that would be of any help.
If I would try and RMA the phone, does anyone know would there be any sign of rooting. I had previously had the phone rooted on the official 4.4 build (using purple drake) and then I updated to 5.0, but didn't root.

LG G3 - D855 (County: Turkey if it is important )

G3-D855 trying to upgrade from 4.4.2, but it refuses no matter what.

Hi all.
I bought a used LG G3, where the guy said this phone had been used to pass around reviewers, so I don't know if this has any factor as to why I'm having issues.
So, issue is, I'm on 4.4.2 atm, and want to upgrade to at least 5, and possibly 6 if this is possible (which it seems to be from what I've seen around the web.) I tried to do it via the phone first, through the built-in update center (current version is V10g-EUR-XX) It sees there is an update for the phone, which I then select to download and install. It then tells me it will download it, and shows the object under my notifications. But then it simply says Cannot download, and just stalls at this point. I've tried both options with wifi only, and over 2g/3g as well.
(At this point I added some screenshots I took, but can't add them, as external links are not allowed for the first 10 posts)
I then tried to go through the LG PC suite, installed the USB drivers etc. When checking for updates, it simply says "Cannot Proceed Upgrade. LG PC Suite upgrades unavailable on this phone."
Where do I go from here? Can I manually update it through the flashtool 2014, or am I looking at rooting this phone, to get be able to upgrade it?
In advance, thank you for your help.
Best Regards,
Dozer.

Can I upgrade directly from 4.4.2 to 6.0? When I was searching the net, I found a website that said I needed to have updated to latest lollipop, before going to marshmellow.

Okay thank you. Can you link me to the correct kdz for lollipop? I'm in northern europe. Didn't seem to be able to find it on your first link to the Marshmellow kdz's.

LG G3 D852 downgrade from 6.0 to 5.0 Lollipop

I have been trying to root my LG G3 D852 on 6.0 mm, i have found that there is nothing out for that yet. I know know that have to downgrade and I have tried but since I'm on virgin mobile so the downgrade file I tried to use bricked my phone so i had to send it back to LG to get it fixed. Is there any other way to downgrade or root without bricking my phone again?
Thanks

Same problem...

Hmmm. I had the same problem as you did with my G3. Same model and everything. Tried to downgrade it using my computer. Can't remember what tool, but it said it completed successfully. When it went to reboot, it would stay on the LG logo for 15-30 seconds, before going to the broken android screen. After a few minutes, it would reboot. Could enter into the recovery menu from the broken android screen, but when I tried to bump the files or flash a rom, there was nowhere on the phone to store it. I think it removed the partitions during the flash, hence why it couldn't store the files. It's not that I didn't have permission, but it showed in the console that there was no directory to mount. Couldn't even charge the phone in the state it was in. Guess it relied on the OS to control the charging. I'll probably try to simulate the phone, with the stock OS, and see if I can find any exploits that could allow for a "safer" rooting method. Tell me if you find anything yourself!

G4 LGUS991 6.0 installation Help!

Hi folks. I have a US991 with 5.1 lollipop that is a replacement LG sent me. I need the 6.0 MM update. I have tried LG Bridge, but it's not recognizing the USB Connection to the PC. I have tried everything besides rooting the phone (am not comfortable doing that). I called/chatted online/and even emailed Tech support for AT&T and LG almost 10 times now, but they are simply not helping me at all. They keep saying I need to wait for available update or they tell me the other party has to resolve it. When I got to check for software update under settings it keeps saying I am up to date. What can I do at this point because I need the update. Thanks for any suggestions.

Its a Driver issue on your PC, its not correct installed yet. My idea : have you dissabled the Automatic update in Windows 7, 8, 10 ? If this happend you must enable it again but can set from automatic to Manual and install the Divers or LG Bridge again. Happend so on my Sytem too.

Thanks for reply. I finally got mobile support tool to work on a friends laptop but when I ran it it shows my software is up to date just like it does in the update center of settings. Why would it not show me any updates at all knowing that my other G4 has MM on it?? Any suggestions. Thanks.
