Hi, thanks for the guide. I just flashed my D850 to kitkat with the TOT method. Very usefull.

The only problem I´m having is that Im currently outside the US using my phone with another carrier sim, I do not know if this might be the reason but I´m unable to update to Lollipop.

Is there any other way of updating rather than OTA?
[G3 General] hyelton:
Nope sadly there's no way, you must have an att sim and be on AT&T for OTA to work sadly.
[G3 General] Fantasia2:
Do you think that if I put in my ATT sim it will work? Despite that I will be using another carrier antennas?

I have not tried it since I was trying to avoid roaming charges.....
[G3 General] hyelton:
It might, but what you do. Turn off your data before hand, pop in the sim and then try over WiFi. It will only update over WiFi anyway.
[G3 General] Sum14u2nvy:
So I should just wait till there's a fix for my device?
[G3 General] hyelton:
There's a fix for what?
[G3 General] BR7fan:
Thanks so much for this. This was any easy task,but a long journey for me. First off I was getting the mtp error,it wasn't letting me connect with my PC at all. It puzzled the hell out of me,because when I got the phone it worked flawlessly. I was getting beyond frustrated at this point. The more I started reading and trouble shooting, I started to figure out it was the phone not the PC. I put in CM ROM and it allowed me to connect, that's when the light bulb went on. Evidently my stock ROM had an error that wouldn't allow me to connect. I took me a not to find a pure att stock ROM that iI could flash with twrp. To make a long story short I was able to flash tot method and it got rid of all the lag I was experiencing when I got iit. Using any browser was torture from lag.

My phone is bricked..no Download mode but it shows Lge

Androidnet USb Serial port

I Tried tots method but it fails with this Exception :

So could you help me By Tot file..My phone is D855.. 32GB
[G3 General] hyelton:
First of all you need to place it in download before it will flash.

Problem

Hello there,

Its nice guide but i got one problem.

After flashing i see black wallpaper no notification bar no software keys phone cant read my sim card and when i open file manager i see no files in internal storage

Please help me
[G3 General] hyelton:
The only way to go back to stock is download mode...

Make sure your using the USB cable that came with the phone have it plugged into your computer, phone completly off. Hold down vol up and put in the cable into the phone.
[G3 General] hyelton:
Did you perform a reset? Did you flash the correct firmware to do with your model? There's several models and you didn't state what's yours and what you flashed..

And well of course they'd be no files, flashing back to stock wipes your phone.
[G3 General] Kristiyan92:
...

Well i download firmware from lgkdz.com i write my imei and download

I think the problem is because internal storage is not formated right? I cannot install apps i cannot download apps etc

Also i cannot lock my phone when i press power button my screen turn off but does not lock the screen and dont ask for knock to unlock

Model:LGD855

Latest Firmware:D85520H_00

Download Firmware Available

this is the firmware i downloaded and its 1.08 GB
[G3 General] hyelton:
Did you try performing a factory reset? Did you do something that could had caused this before flashing back to stock?
[G3 General] Kristiyan92:
...

Yes
[G3 General] gameplayerdo2:
so what do you do when you follow this method and everything goes fine but then your phone doesn't power back on at all?

and when you plug it into the computer usb and it goes boump boump boump boump..
[G3 General] hyelton:
You pull battery, put it back in and turn the phone on....
[G3 General] :
A reminder....

If you experience problems and need help, post your issues clearly with details, respectfully.... And hopefully you'll find help.

And as with everything in this hobby and on XDA, only you are responsible for what happens to your device. No one forced you to tinker with your device. If you can't accept responsibility for problems that occur when flashing and Modifying your device, then don't do anything and leave your device alone.

Thanks,

Guys, I am trying to flash a stock ROM (20A) on my G3 (D855P, 10C). I installed LG United Mobile Drivers, extracted the LG flash tool, downloaded the kdz file and tried to start flashing, but I keep having this error:

[IMG="Error"]https://lh4.googleusercontent.com/-8jdysF9yVU0/VS_QDCYh9GI/AAAAAAAAGUg/cz4JpuC25a0/w1538-h865-no/20150416_115455.jpg[/IMG]

These lots of question marks and phone stays on 0% progress.

If I disconect the phone, I can remove the battery and the phone works well. I just wanted to update to Lollipop, because it didn't arrived at my carrier yet.

I tried in two different computers (Win 7 x64 and Win 8.1 x64), and I keep having the same error. Also, I tried to change DIAG to CS_Emergency, samething.

One thing that I noticed is that I can't select any different country when flashing. If I select "different country", nothing appears on the second box. Don't know if this is related to the error.

I also tried two different ROMs (20A from Poland and from Brazil), same error on both.

Does anyone know what's going on? I will put the Log file that I got from LGMobileUpgrade folder down below.

Thank you very much!
[G3 General] hyelton:
Did you make sure lgemodem shows up under ports in device manager?
[G3 General] Lucas_Skyline:

[G3 General] Lucas_Skyline:

EDIT: I reinstaled everything and now it starts, but stuck on this error. Any solutions on that?

Thank you very much!
[G3 General] hyelton:
Phone is in download mode correct, using the factory usb cable and not in a usb 3.0 port? Try another USB port?
[G3 General] n0phearz:
Just ran the TOT method. Everything worked fine up to 94%. Then the fail icon came on. My phone has been sitting at the Factory Reset Status 3 Screen for the past 5 minutes. The Flashtool says "Fail to get Mini OS Status" then one line below is FAIL!!!!! Factory_BootComplete.

Not sure if I should just power down the phone and say screw it or if I'm missing something and it's actually okay to do so.

Edit: So I pulled the battery and started it again. It's running 4.4.2 which is what I was hoping to see rather than a bricked phone.

Time to figure out how to install a recovery followed by a ROM for D852. Anyone have recommendations? I'd like to customize my phone with custom icons and sounds if possible. I've seen some nice custom setups.
[G3 General] hyelton:
About the flashing go back and read the op :p its stated its supposed to almost always fail, and anything after 85% is just rebooting. And at the blue screen you pull the battery :P it's all in the OP. For recovery download twrp manager from the play store.
[G3 General] Webster200x:
If you fix it please let me know because i have the same problem.

Thank You.
[G3 General] zzzijo:
Hey guys .. I'm on 4.4.2 but I flashed TWRP and after receiving OTA, tried to update software but got stuck in TWRP .. Found a fix for that but is there a way to revert stock recovery ?? Or there is only way to flash rom via lg tools ?? [emoji16]
[G3 General] reddysai:
Hey can any one tell me where I can find my kdz file.

My software version is V20h-twn-xx.plss. I really want to get back to kitkat
[G3 General] hyelton:
Then download a kitkat firmware and follow the Op
[G3 General] miranwar:
no signal after downgrading

Im having the same issue as well. no signal at all. tried factory resetting over 5 times but still nothing. Were you able to find a solution for this??
[G3 General] finbaar:
Can someone recommended me an Open Lolipop . kdz for my 16gb D855? I am in the UK and the one in the link for this thread is actually for the D802 (my old phone!). There are a several possibilities but I would appreciate help from someone who has done this.
[G3 General] Klyupp:
I installed the LG drivers from the OP but when I connected my phone to my computer windows didn't recognize it and started downloading some other drivers. Now my phone shows up under 'Universal Serial Bus Controllers'. How can I let it recognize my phone the correct way and show up under 'Ports'?

Thanks in advance..

Nevermind figuered it out, procedure worked perfectly!
[G3 General] hyelton:
[Guide] LG G3 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

Huh? All links in the op are for the D855 ,D850, and so on for tuthe G3
[G3 General] ultrasuper:
A few questions

Got a used D850 and will use it on an AT&T MVNO. It's unrooted right now.

Does doing a TOT factory reset erase/format *all* data completely? Like new out of the box? (except SD card and SIM of course)

Is it possible to make a "TOT" of my current 10F ROM in case I want to go back to it? I assume not since you're hosting 10D..

Any idea if on the phone, I can request (and get) an OTA update? even though I'm on an AT&T MVNO, and not main AT&T itself?

Thanks for the help
[G3 General] finbaar:
storagecow.eu/index.php?dir=Xda/LG+G3/Stock/United+Kingdom/

As you can see the UK Open is a D802 file which is at least 500mb larger than the D855 files. It is quite ironic as I just updated my D802 and couldn't find this file so used the Spanish Open firmware.
[G3 General] hyelton:
Ohh lollipop firmwares would be in the lollipop folder at the moment. That's where I was looking.
[G3 General] hyelton:
Yes it will wipe everything. But in that case why not just perform a factory reset since it's not rooted?

No you cannot just make a tot file.

OTA is tricky. It may or may not. Only you can try. Most likely it won't though.
[G3 General] ultrasuper:
Well, that gets to my next question then.

Software Factory Reset via: Settings, Backup and Reset, Factory Data Reset

Master reset with hardware keys via: Power Off, Press + Hold PowerOn and Volume Down keys

This Flash from the OP

Are all these methods as complete (same end result) as each other?

Lastly, is there any way to make a nandroid of my current system including the 10F version of the OS I currently have? To be able to go back to it after I load another version (L) or a different ROM onto the phone?

Thanks for your great work and support btw!
[G3 General] hyelton:
Just perform a factory reset via software. Flashing a tot is mostly for people wanting to downgrade, upgrade, or going back to stock from root or roms.

If you'd like to backup you'd need root. But the tot in the Op will work to restore you back in case you ever needed to:)
[G3 General] almmpt:
Today I make another downgrade with the D85510e_00.kdz with CSE, everything went very well but when I finished my android configuration I miss the fallowing stock aplications:

Calculadora 4.20.10.apk

QuickRemote 4.20.19.apk

Rádio FM 4.20.12.apk

RemoteCall Service 4.0.38.apk

SmartWorld 4.1.8.apk

TalkBack 4.1.0.apk

Tarefas 4.20.9.apk

ThinkFree Viewer 4.1.14.apk

Transferências 5.10.40423.apk

Voice Mate 2.1.8.apk

Widget contactos favoritos 4.20.4.apk

These are portuguese names for the missed aplications.

I go to LG Update Center to check if they are available for download but none of the missed aplications is available.

How can I fix these problem because I go sell my White LG G3 (I have another LG G3 Titan for me) and I want that these aplications are installed?

Thanks
[G3 General] ultrasuper:
I know. I just wanted to know if I could save a 10F build, since the *only* TOT for the D850 is 10D.

Once I upgrade, install a ROM, whatever, I can never get back to 10F, just 10D in the OP.

If I root now, while still on 10F, then I can somehow make a "snapshot" of the system to go back to at a later time?
[G3 General] hyelton:
[Guide] LG G3 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

You can root and do a twrp back up. But the only difference between 10F and 10D is 10F is newer. But the only way to completely ever put it back to stock is flashing 10D

I really wish there was a newer tot but there's not sadly.
[G3 General] ultrasuper:
..And if I restore that nandroid, I'll be back to 10f, BUT with TWRP still installed as recovery right?

And there is no way to remove that twrp and be 100% back to where I am right now (10f, unrooted, no twrp).

Only way is to use your method here in the OP which would do that, BUT it puts me at 10d.

Have I got it?
[G3 General] xurena:
Lg g3 - d855 - v10l-esa-xx

Previously my LG G3 runs on V10A-ESA-XX.

Flashed with V10L-ESA-XX :

- battery improved, stays longer.

- UI feels faster than V10A

Happy with it. Won't flash it with Lollipop yet. Going to wait for a while until many users post good experience with Lollipop.

Heard still so many problems with Lollipop.
[G3 General] PWn3R:
Posting this here in case anyone else is on VS98523A and needs to go back to stock. Download the VZW VS985 drivers version 2.2.0 from the LG site directly NOT the ones from the OP here. If you don't your phone will not connect to the PC and you certainly can't use the KDZ. I didn't try with the TOT but they were the only drivers that worked for the KDZ using the LG FLASH TOOL 2014. This was tested on Windows 7/8/8.1 and 10 Enterprise Preview. TLDR: Use LG VZW Drivers Version 2.2.0 or get wrecked.

Hi, can I use this method to convert my US Cellular US990 G3 to the Verizon variant and possibly enable GSM portion if there is any in this phone? I am trying to convert this US990 to another variant to see if the GSM radios will enable.
[G3 General] hyelton:
Never flash another model onto a phone.

Verizon is cdma just like us cellular. Flashing doesn't enable bands just like that.

Why don't you just pop in a other sim and see what happens? Verizon and us cellular ones should come factory unlocked. If your meaning because you cannot get 3G and only Edge on another carrier you cannot fix that.
[G3 General] johnny13oi:
The Verizon model is CDMA but also has GSM radios on there as well as the Sprint CDMA version. The US Cellular US990 model does not have GSM at all. No 3G no EDGE nothing. It does have LTE. So I am wondering if I could flash either the Sprint or the Verizon flash onto there and hope that this enables the disabled hardware on the US Cellular version.
[G3 General] hyelton:
Us cellular version is almost identical to Verizon. It would be a software thing not an hardware problem stopping it.

Are you sure it's not just locked? If so you'd need to call or take it to us cellular. Just tell them your going out of the county for a few days.
[G3 General] johnny13oi:
Yeah that's why I want to flash the factory Verizon one to it. The US Cellular phones have their GSM parts disabled. I don't know if its through hardware or through software but even when unlocked by US Cellular themselves they do not activate the GSM part. The GSM part was never certified by the FCC so it was disabled in the US Cellular ones.
[G3 General] hyelton:
GSM is not disabled in the U.S. cellular ones. If it was you wouldn't have LTE. LTE is GSM :p.

Also us cellular would only unlock the phone for gsm there's no such thing as unlocking just a plain cdma phone. You can try flashing a Verizon one but its at your own risk. It mostly will work but there could be problems and bugs.

Thank you

I just successfully flashed my G3 D855 back to stock from CM12. :o
[G3 General] Xijek:
First it was stuck on IIRC [710] Fastboot mode started and I was having problems flashing a new KDZ and using the .tot method, but after like 30 tries it suddenly worked just to get stuck in the factory 2 and now every time I try to use the LG Flash Tool I get the same error(Can't change to download mode, basically never goes after 6%). Also tried the Board DL instead of upgrade DL.

Tried with a different computers, different cables, different .tot files, different usb ports, different flash tool versions.

I really have no idea what to do now and I'm getting desperate.. Any help would be greatly appreciated.

i'm flashing the TOT...and I get the weirdest message, ever......

S U Galaxy S4 05.0.1 Hrev_10

Model ID Different

Check your model!

...what?

lol....... he told me he downloaded a program for a samsung and it bricked his device, but I'm seriously wondering what he did...

cuz the TOT won't flash, it keeps erroring out saying the device model is a GALAXY S4....

how do I flash a TOT without a check?
[G3 General] hyelton:
I bet he tried to flash a s4 rom lol. Which is really stupid. You'll need to use the mega lock dll file in the Op that's for that. If that don't work you'll need to use an hex editor to change your model.
[G3 General] solidus636:
I replaced the file... just like the guide said to....

been flashing and rooting for 6 years.....

how do I use a hex editor to do this...what file would I edit,? do i need QPST to connect to the port?
[G3 General] hyelton:
[Guide] LG G3 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

I'm talking about a different file that's in the Op. There's another DLL file for if you have the wrong model mismatch. That sometimes will work. Use the dll in place of the D850 dll in lg flashtool

QPST? Isant that for programming CDMA phones? No you don't need that.

Just google lg wrong model hex editor.
