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.

D852g Cant revert to stock

Good morning
Im using a Canadian version of the LG G3 D852g on Videotron network.
I have been able to root and twrp the phone no problem. I have tried most of the roms available (candy cm 12 etc)
I installed cloudy 2.5 for my model of phone and since then i have been unable to revert to the stock OS via the KDZ method or TOT.
What is odd is that the KDZ worked no problem until after i installed cloudy 2.5
The KDZ method would now stall at 2% and indicate that it can not find my device. (yes i know drivers com port 41 etc etc etc)
I downloaded tot file and dll required for my device and when i run the LG flash tool.
SO then i tried the TOT method to revert to kit kat. and this is where i got a weird error message

Any help would be greatly appreciated

Root/TWRP on 6.0 Bell LG G3 D852

Hey everyone, firstly I would like to apologize if this question is in the wrong place. This is my first post so I'm not overly sure where it is correct but "help" seemed good to me.
I have been trying to get XPosed working on my LG G3 for a few days now but it isn't working. When I go into it, it says "The exposed framework is not installed. Please download the latest ZIP file and flash it manually via recovery" which is fine but I can't get TWRP on my phone. I have tried using Flashify and the TWRP manager but when I attempt to boot into recovery I get an error saying "Boot verification FAIL". I don't know what information is relevant so this is everything about my phone.
Bell LG G3 D852 (I am 99% sure it is Bell, my contract is with Virgin Mobile)
I root with KingRoot 4.9.5
My android version is 6.0
Kernal Version is 3.4.0
Build Number is MRA58K
Software version is D85230e
I would really appreciate any help anyone could give me!
--EDIT--
Nevermind, I came across my answer! If anyone has this problem this is what I did and it got the job done

Help save a bricked lg g3

:crying:
My issues is quite complicated. Please be patient and read on.
Less than a week ago, I bought an LG G3 D855. It wasn't brand new and definitely out of warranty.
It was on the 4.4.2 Os version but I couldn't update it because I couldn't locate the UPDATE CENTER and after some research online, I found out it was because it was rooted. I couldn't find a Supersu application anywhere on the phone anyways but Root checker confirmed that it was rooted.
I downloaded the stock kitkat firmware in a .tot format and I tried flashing using LG Flash Tool for TOT but it failed because "Device version is different"
I checked the Imei online and it stated that the device is a Sprint LS990 but the details embedded in the phone all say it is D855
I checked online and found a couple of posts about this error and one user said he was able to fix it by flashing the actual Sprint .tot with the lg flash tool. I tried that but it didn't work. It still said "Device version is different. Check BIN or dll"
I checked online and found results pointing to a generic .dll file for G3s and I downloaded it but when I used it on the Flash tool, it resulted to an error "CrossDL blah blah"
So I found a Marshmallow kdz file. LGUP won't see my device model so I was able to flash it after editting the software in my build.prop to D85510n.
***I have always changed the port to COM41 in all the steps I used
The LG UP detected my model and it flashed to 100% but got stuck on a bootloop by loading the lg screen, freezing and restarting by it self. It never gets to the homescreen.
I downloaded lollipop kdz reflashed using LGUP in a form of downgrade and it got to 100% and got stuck at the lg screen while trying to reboot.
I redownloaded the stock kitkat rom and used the Lg flash tool but it failed. It said 'PID null IMEI Null"
I used LGUP to reflashed. It came to my understanding that the LGUP can flash both kdz and tot. So it flashed to 100% but got stuck at the lg screen and I have tried all I can but it is stuck. It can go into download tho. I don't know what to do about the IMEI. I don't know if the last flash retrieved it. I don't kniw what to do.
It no longer shows as LGE AndroidNet USB Serial
Please can anyone help me?
I just need my phone to work again. I was stubborn and now I regret it. I should have just stuck to kitkat. I'm so desperate to get my phone working that I wouldn't mind Android Froyo Os if it was ever possible.
PLEASE HELP!!!

I think you have to repair the IMEI...
maybe this can help

I think that he forgot to hard reset after flashing the kdz.

i completly know what you should do:
1: force your phone into qualcomm 9008 mod.
2: use board diag unbrick instruction and it will boot on download mod. for unbrick you will need best kitkat tot for your G3 model.
3: flash best lollipop or kitkat tot to make your phone alive
and then flash it with any kdz you want(it should be for your G3 model)

pls help me
Apparently, it seems my bricked phone keeps disconnecting during flashing process. I dont think it the fault of the cable because I have used different ones and they all seem to work fine with other phones. I have tried a different computer and still the same results. it connects as qualcom 9008 but once I try to start flashing, it disconnects and interrupts the flashing process. my phone just shows a grey screen now when I power it up with the battery in. also, I was trying to upgrade from linear os to the latest linear os. I cant fine the tot out there so im using zv6 currently. could this also be the problem? thanks in advance

LGFlashTool insanity.... helpppp

I have a g3 d855.
I was running 30b rooted and decided to tweek the ui soft keys (big mistake).
I ended up bricking but managed to use LGFlashTool without any problems to go back to stock "LGD855AT-00-V10e-EUR-XX-JUL-08-2014-32G+0.tot"
Then I installed 30n and found out it can't be bloody rooted.
I thought it would be simple to revert back to stock. 8 hours later and I am still stuck.
I keep getting "model information check fail!"
Is there any other tool for flashing the stock files as I am loosing my freaking mind here.:silly:
Thanks
