Twrp will be removed once and if the flash actually completes. And no twrp has no part in going back to stock. It should take at least 5 minutes to flash a firmware so 100% in a few seconds means it's not flashing. You could try using the old tot method flashtool with a tot.

And be sure your using a USB 2.0 only port.
[G3 General] Aid777:
I have tried all three ports on my laptop, no joy. Download mode I can get into fine. Open LGUP, change filename to *.kdz select option in windows to bring up the file, then click on that, then exit LGUP, then open up again. BIN is ticked, refurbish is highlighted and it failed. TWRP open at about 87%

Any ideas please? I've had a loot for a tot file, but cannot seem to see any. I tried reflashing zips in TWRP and that did not work either.
[G3 General] hyelton:
Are all ports on your laptop USB 2.0? That's what matters. Remember some newer computers only have USB 3.0. If all ports are USB 3.0 it's not going to work

Have you not tried using the old tot method I mentioned in my last reply?
[G3 General] Aid777:
I have a Lenovo G50 laptop which apparently has 1 USB 3 (blue connector) and two USB 2.00

I am downloading a 2GB TOT file now v10e

UPDATE. I used TOT method with flash tool and the phone is now running Android ver 4.4.2

Now I need to update to MM (DL that now with PC Suite) and root and all will be fine......

Thanks for your help.

UPDATE. What the hell? I cannot root MM, how come? that's disappointing

UPDATE again! So I had the 'official' MM on my phone that was upgraded via the PC Suite. I then used LGUP to flash the 'same' version and it worked fine. Now have the MM .kdz version and my phone is rooted again.
[G3 General] bender_007:
You can but it's not to be discussed in this thread. Seek for "root d855 6.0".

[MENTION=2607037]hyelton[/MENTION]. Do you think you can update the OP with [MENTION=3279781]bender_007[/MENTION] so the instructions to TOT and KDZ stock KitKat and Marshmallow for our LG G3? I had to go through quite a bit of searching and reading the OP over and over again to get stock KitKat and Marshmallow flashed. I'm not saying the instructions are bad, but the instructions can be clearer and more detailed at the same time.

Having said that, I am running stock Marshmallow on the LG D852 (Fido/Rogers) right now and LTE band still doesn't work. The APN is correct and LTE randomly stopped working one day 4 or 5 months ago. Not sure what I can do to get LTE back. Is it possible the LTE hardware on my phone died? Also I just rooted the phone but then bricked it when I tried to install TWRP via Autorec. Is there a way to install TWRP and recover from this brick? I can't even get into Download Mode now.
[G3 General] hyelton:
[Guide] LG G3 Stock Firmware (Go Back to Stock) KDZ &amp;amp; TOT Method With LGUP

I don't understand what you mean update the OP? With bender_007 With what? The guide is mostly straight forward

There's 3 methods.

Tot, kdz, and LGUP which flashes both.

And when on MM you must use LGUP to flash firmwares or downgrade.

About LTE if it was hardware related you'd loose service all together. The last person who had lte issues with the Canadian model it turned out the entire time he was using an incorrect APN so be sure your using the correct apn 100%.

Does the phone power on at all? If it shows no signs of life it's bricked sadly. But if you turn on and see the lg logo and If there's no recovery you must get the phone into download mode to flash it back to stock.
[G3 General] geokilla:
Yes I know there are three methods, but some of them are outdated (2014 method for example) and the instructions can be unclear. Just that if you are able to change things up and redo the instructions, it'd make the guide a lot easier to follow and simpler to understand. Right now information is all over the place.

For the LTE, the APN is 200% correct. It just randomly stopped working >.<

Was able to unbrick the phone using this guide: http://xdaforums.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091
[G3 General] hyelton:
Okay good :). But that's strange tried calling carrier? I do know AT&T I've had lte issues when the imei was set incorrectly in the system.

Did you also check under settings, mobile networks, and it's set to GSM/WCDMA/LTE?

The 2014 method hasn't changed at all despite being a few years old since it's the old lg flashtools, as now it's only really needed for those that cannot get LGUP working correctly.
[G3 General] bender_007:
I would just include the unbrick link so people know, the flashing methods are perfectly explained.
[G3 General] dornz:
Tryd to flash back to kdz stock but for some reason LG flash tool does not work on w10 os keeps cutting out just when its doing check to see if anythimg on the os will conflect with it. Which then says windows cant communicate with phone ?
[G3 General] hyelton:
Was the phone running MM 6.0? If so that's why your supposed to use LGUP if it is. These tools work perfectly fine with windows 10
[G3 General] dexmorf:
Hi guys. I have AT&T D850.

Is it possible ever now to flash STOCK Marshmallow?

In Any way: kdz, TOT or zip?

Debloated is very desirable :)

(I'm on custom mm now. But looking for a way how to test latest stock for D850. I'm not in USA, and have not att SIM, so no OTA)

What build is last official for this Device - v30n?

[G3 General] Aid777:
I mean no offense or disrespect to the OP (he offered some help earlier which I am grateful for) but do these guides state only use USB 2.0 port and that LGUP only seems to work if you are already on the 'proper' stock unmodified Android ROM? I'm still a bit ignorant about flashing and I did not know about the USB 2.00 (although I do seem to recall reading it it someplace ages ago). Also is the LGUP .kdz. flashing supposed to work on an already flashed .kdz ROM or st it only supposed to be used on the official ROM (for me, the LGUP flash only worked when I was on the 'proper' MM ROM that I got when I updated with the LG PC Suite).
[G3 General] hyelton:
Sadly there is not, and likely never will be. Due to the AT&T model being tot method only. Still only official way is to ota update.
[G3 General] hyelton:
Yes you can must only use USB 2.0. Out of the hundreds of thousands that's used this guide USB 3.0 only works on a select number of intel motherboards only 1% will USB 3 work.

LGUP works with anything, the reason it has the issue is detecting the model weirdly. A person could edit the build prop of a customized rom and it will work flawlessly.

It doesn't just work on a kdz or tot flashed roms, it can basically work with anything. If it only worked on a official stock rom the LGUP method would be useless.

LGUP also flashes tot files as well not just kdz files.
[G3 General] rhrokib:
Im in a big trouble. i was using fulmics 6.1 on my LG F400L. it was running well. But i tried to install Android N-ify to my phone and after booting up my phone says " SystemUI has been stopped" and I can't access it anymore. its not a big deal since i can't even boot into recovery. I don't know why hardware keys doesn't work for me. So only one option is left for me is flashing my phone back to stock.

Here is the main problem. Via KDZ method my phone stucks at 2% S/W. maybe its for Fulmics 6.1

Again if I try to downgrade via LGUP my phone is showed as unrecognized.

Now , how can flash my phone ?

what method should I try ?

Please help me.
[G3 General] hyelton:
Try the old tot method and see if that works if there's a tot file for your model.
[G3 General] dexmorf:
Can you explain why? D855 has bumped stock v30n. It is full stock room, just copied from the phone and bumped, no other changes.

Why it is not possible for D850? Download dump from officialy updated phone, bump it, (may be replace modem on LP) and make a zip ROM for the recovery.

What did I think wrong?
[G3 General] hyelton:
Well that's possible, but then it's no longer an official firmware and not related to this guide. This thread is all about 100% stock.

[G3 General] geokilla:
Yes it's set to GSM/WCDMA/LTE. I don't think the IMEI is even registered with Fido. They've never asked for it in the past anyways. If you need to register IMEI with a carrier, than how do users like I with my OnePlus One use LTE?
[G3 General] hyelton:
No clue but I've seen it happen before with several carriers over the years. A few weeks ago I had put my sim in my old G2 for about and hour and doing that screwed up VoLTE until I called my carrier and got it fixed so strangeness does happen.

But I've seen several users with Canadian models in Canada have lte issues across carriers. But a few it turned out to be an apn issue.

I have a G3 D855 and it keeps getting Demigod kernel crashed even if I factory resetted. so I tried using lg flashtool 2014 via CSE flash but it gives me error.

"Connection to server failed. Please try again in a moment"

I am already at Download mode. Hope someone can help me flash this

Using LGUP method. Makes the model Unknown on selection of com port so I cant use it either
[G3 General] hyelton:
[Guide] LG G3 Stock Firmware (Go Back to Stock) KDZ &amp;amp; TOT Method With LGUP

2 things, first of all connection to server failed is not an error.. it's supposed to say that and you drag over the window. And if your not running MM 6.0 you'll see that it has actually been flashing your phone and interrupting it can cause problems getting it back to stock if you clicked exit

But if you where running MM then you must be using LGUP.
[G3 General] amnher:
The phone is still kitkat. So what to do?
[G3 General] hyelton:
Then follow the normal flashtool method and flash it back to stock, When it says network error drag the window out of the way dont click quit, And if your phone is in download mode and your using a usb 2.0 port it will flash.
[G3 General] amnher:
I am having a problem right now. It doesn't go to download mode. When I try to hold vol up then plug usb. It goes to screen with download mode but after a few seconds it shuts down and does not go to screen with USB and percentage Icon. Any solutions?
[G3 General] amnher:
Here is my current screen

Sometimes it shuts off and sometimes stuck on there.

The phone is still crashing with demigod handler screen.
[G3 General] TheTuss182:
I have a VS985 with TWRP, CM13, and the 35b bootstack. and I want to go back to 100% stock everything (KitKat). I will be using LGUP with "VS98510B_03.tot" in "Refurbish" mode. Is there anything else I need to do? I have read bits and pieces about needing to flash a stock-based ROM before I do any of this - is that true? What ROM would be recommended? Thanks!

Edit: I would have no problem just flashing the latest KDZ (48A) if that is any easier.
[G3 General] hyelton:
Yes you'll be better off flashing a stock based VS985 based rom first. As you'll have problems getting it detected in LGUP
[G3 General] TheTuss182:
The current plan is to flash this stock ROM in TWRP, then follow the LGUP guide to flash either the 47A KDZ or 10B TOT. Sound like a good way to go?
[G3 General] amnher:
Hope someone can help me
[G3 General] hyelton:
No clue. If it successfully flashed back to stock and your getting that it would definitely be a hardware problem.
[G3 General] amnher:
It didnt proceed i was retrying to flash via kdz flashtool. The last time i can still access download methon but error occured and now i cant enter download mode anymore
[G3 General] hyelton:
What was the error?

And what do you see in device manager when it's plugged up to the computer? You may need to follow the soft unbrick guide if you see anything with 9008 on it.
[G3 General] amnher:
The one I posted

Sad thing is no response from Device Manager :( yesterday it is still detected on download mode with that picture then shuts off. If I plugg the phone on the PC while off, it shows battery with loading icon but eventually it will lead to demigod kernel crash
[G3 General] hyelton:
Yeah but I already responded that what you stated was NOT an error. Connection to server failed is not an error. That's supposed to pop up. You drag it out of the way and originally you would had seen that it was actually flashing your device. Clicking exit/quit would had interrupted the flash.
[G3 General] amnher:
Yeah so I retried it but it came to this when trying to go to Download mode by holding vol up then plug in USB, it shows Download mode icon on the center but after sometime it will shut off or otherwise gets stuck with there and will not go to the proper download mode screen(The one with percentage and USB icon)
[G3 General] hyelton:
That screen in your screenshots above IS download mode. Depending on what you tried to flash if it was an older kdz it changes the look of the download mode. Older firmware had a different look when on download mode.
[G3 General] amnher:
But it shots off after awhile. No detection on device manager. Before this happened it goes normally

from here:

to here

But now it doesn't its stuck on the screen like on the first picture then after sometime shuts off itself and the phone does not turn on and I need to reinsert battery. I flashed the KDZ from your link inside the marshmallow folder with PHILIPPINES D85530a.kdz
[G3 General] hyelton:
What do you mean by shuts off? You if your running flashtool and it shuts off then it's rebooting due to a finished flash.

Are you looking under commutation ports under device manager for it? If your running windows 8 or 10 you may have to unhide it
[G3 General] amnher:
Flashtool is not running yet. Shut off meaning it turns off. I am using Win10. Before trying flashtool it appears on my device manager but after the incident, no response anymore. Maybe I corrupted laf partition when I failed the first flashing process of KDZ? :rolleyes::rolleyes::crying:
[G3 General] gfunkzero:
I had the same problem, whenever I tried to flash with LGUP it just took me to the TWRP screen, so the flash doesn't work if TRWP is installed..

I had to use the LG flash tool which worked despite the install getting stuck on 9% :eek:
[G3 General] amnher:
Anyone have the same experience with my case?

I was thinking if my laf partition is damaged
[G3 General] amnher:
Just an update. i was able to revive it using hard brick recovery by shorting pins. I used this tot file

BIN_LGD855AT-00-V10e-EUR-XX-JUL-08-2014-32G-0.zip

So everything now works fine

But I upgraded to marshmallow via KDZ method from the first page and used the PHILIPPINES D85530a.kdz file from the link on the first page. And now I am getting this error:

How do I fix that?

1. Connection to server error is supposed to come up. It's not an error. It's normal. You drag the window out of the way.. it's not supposed to have a connection to the server.

2. Your running MM 6.0 , you cannot use lg flash tools. You must use LGUP only this is all stated in the OP :)

Hi guys!

I just bought a G3 from amazon

I think it comes from Italy because It has a lot of bull**** app inside from TIM (an italian operator)

I have:

model: LG-D855

android version: 5.0

software version: V20n-222-01

I already rooted it and install twrp but I have this message: "secure boot error"

From what I have read, the easier things seems to be:

- downgrade to kitkat

- get root again

- install twrp

- custom rom

is that right ?

If yes could you tell me which files I have to download because I am a bit lost with d855/european/italian thing ;)

Thank you !!

As stated in the op if your having issues downloading use a download manager.

When downloading large files always use a download manager. It makes things so much easier and sometimes faster. Something like Internet download manager or Free download manager.
[G3 General] FaserF:
Just downloaded it again with Free Download Manager.

The download was finished faster there than in chrome, but I havent thoght about it as I am having a 200mb download range, which is quite fast.

So my D855 is stuck in download mode and LG up does not work LG flash2014 tool does not work and the only option left to me is TOT Method but instructions

Are abit weard.., so I DL kdz from link. there was no dll in link.. then you say extract tot from zip ...what zip ?
[G3 General] hyelton:
First of all your going to need to explain "does. It work".. what do you mean does work??

And if your running MM 6.0 you must use LGup there's no other way.. so using the other tools would be pointless.

I don't think your following the guide correctly. Instructions are not weird The tot method guide you'd see you download a TOT file. you don't use a kdz with the tot method. You extract the tot file from the zip file you download in the OP.
[G3 General] dornz:
OK my bad on kdz file instead of tot I just spotted that there[emoji12] so your saying LG up is the only way.. will try again later thanks for info

Slightly confused. If you follow the guide in the op you shouldn't be getting security error. Unless your saying you got that after attempting the root? I have no clue on root with anything when it comes to MM. For anything other than stock this is not the thread to really ask in for that.

But if your getting security error you'll need to reflash back to stock.
