I KNOW, RIGHT?

I just did the exact thing you are trying to do. Last night, in fact.

Follow the directions in the third post in this thread to get yourself downgraded to kitkat. (One typo in that post - don't worry about finding LGUP_8994_DLL - just use the LGUP_8974_DLL that comes in the LGUP download zip).

Then you'll want to root the phone using any of the methods given in this forum. (I used the "One-Click Root")

After you're rooted, then you'll want to install the "BUMP'ed" TWRP recovery.

Finally, after you have a good recovery installed, choose a ROM and install away. I'm new to this phone, but I assume that only "BUMPED" roms can be used, and the only place you'll find bumped roms is in the AT&T LG G3 area. (If I'm wrong, someone correct me?)

If you can't find something, post again, and I'll help you find what I found. I'm no expert, but my experience is about as fresh as possible.
[G3 General] justinxfan:
I downloaded a KDZ file for my phone, however LGUP only seems to accept TOT files. I cannot seem to get LGUP to select my KDZ file.
[G3 General] hyelton:
LGUP accepts both. For kdz choose upgrade, select the kdz then back out and choose referbish.
[G3 General] justinxfan:
Okay now LGUP is stuck at 9% and it says Start TOT Download. However, I've left it there for the past 5 minutes and nothing is happening. Is this normal?
[G3 General] hyelton:
Does your phone show any progress? Your using a USB 2.0 port right? And LGUP rebooted it into download mode when it started? So it's in download mode now?
[G3 General] justinxfan:
NVM I just waited another 5 minutes it flashed. I'm now at 85% and it says Waiting for reset 120 sec. It appears to have succesfully flashed. My phone now has the android is starting screen.

Thanks a lot for your help!
[G3 General] hyelton:
Awesome glad it worked for you :)

And your welcome!
[G3 General] kent_geek:
Hey, it sounds like you made some progress before I could reply. I was under the impression that KitKat is only available as a TOT file, and that KitKat is the only version which you can successfully root. But like I said, I'm an LG noob, so if you got where you needed to go, I'm not terribly surprised.
[G3 General] hyelton:
Not sure what you mean? Yes the D850 yes it's tot method only for any AT&T firmware. Remember this guide is for more than just 1 model. Which there's tons of KitKat kdzs for. Just not AT&T models.
[G3 General] Bican:
Revived LG D855 (Last working on MM 6.0.1) ...got soft bricked. Tried to flash with KDZ, worked, still stuck on bootloop. Tried the tot method with KK tot and dll and got a hardbrick. Could not flash anything with kdz method. No power on, no download mode, no recovery. Used qualcomm method and flashed all partitions with 10a...then 10e and then 10a again....because i've got that Kernell error. Stuck at lg logo, when try to boot in DL mode it gets stuck at that screen and restarts into qualcomm mode. I can't use tot because i get model information check fail. LGup the same - model unknown. Sugestions ?
[G3 General] Turkishflavor:
so im trying the first method, but it does not work phone stays at 0% and the tool shows "can not connect servers" what to do now? :(

I selected the kdz file and it says "connection to server failed" try again in a moment. lol

edit: ignore the message and just leave it like that. will work then
[G3 General] hyelton:
It IS in the OP..

With the phone off, press and hold either vol up or down while plugging in the USB cable that is connected to a USB 2.0 port.

Or if using LGUP and your phone boots into android you turn on USB Dev mode and when starting the flash it will reboot itself.
[G3 General] mdm_:
So, this thread is massive and confusing. As of December 2016, what would be the preferred way to return to stock on a D852? I used the 2015 TOT method once before to return to stock KK from CM12.1, but now I'm on CM13 and I bought an unlock code and the seller stays it will only work when input on an unrooted stock ROM. Can I still use the 2015 TOT method and go all the way back to KK, then unlock, re-root, flash TWRP, flash CM13, etc?
[G3 General] DJRobBlaze:
Yes, I sent you a PM.

What was the unlock code, and why did you have to buy it?

? Sent from DjRobBlaze's VS985 ? Rockin' ? Fulmics 6.6 ? using Tapatalk. ? ®
[G3 General] hyelton:
Since your on CM you'll first need to flash a stock based rom first via twrp. Running CM causes issues with flashtool. You maybe able to unlock your device with a stock based rom as well, but if not just follow the method of the available tot or kdz for your model.
[G3 General] hyelton:
The unlock code is for unlocking the device to be used on another carrier.. and in which CM cannot be used to enter the code device must be running stock rom.
[G3 General] Bican:
For those who can't enter in Download mode after reviving the phone.

Skip installing laf partition while following board diag guide.

After that when flashing sbl1, instert battery, flash sbl and when resets press volume up.

With this you will enter fastboot mode and flash your files.

With board diag, to flash that files, took me 10 hours.

Phone still not fixed because of a kernell panic.

I will come with details if i will fix it in fastboot mode.

Hello guys!

I want to update my G3 from 5.0 to 6.0,with those tools and 30c KDZ.

But I can't find any valid download links on internet,can anyone help me find out?

My phone's model is D855 32GB ,and I'm looking for a Hong Kong version of 30c,but I can download the KDZ file from those website below:

h ttp://lg-firmwares.com/lg-d855-firmwares/

or

h ttp://lg-phone-firmware.com/index.php?id_mod=41

The file I wnat to download is D85530c_00_0830.kdz

Please let me know where can I get this file.

Thank you guys so much.
[G3 General] hyelton:
First of all those links are not allowed to be posted here due to scammy and virus infected ads.

If you could download from the site above why not download it then? Also there's tons of valid links in the OP.
[G3 General] CesarRaimon:
Hello, I checked the kdz files and they're all for F460, F400S, F400L and F400K. But mine is F400 plain, so I was wondering if one of those would work on it? Thanks in advance.
[G3 General] hyelton:
There's was never any plain F400. They all will have a letter ending. The ending letter is the carrier
[G3 General] CesarRaimon:
I'm incapable of taking a picture right now, can't boot into the system either but on the back underneath the battery, the model number is written plain LG-F400 ?
[G3 General] hyelton:
Yes I've seen that, but theres no plain software for that model. That model was only made for one of the few South Korea carriers.
[G3 General] CesarRaimon:
So none of those would work with it? I believe this is an unlocked version, so not sure whether to take the risk or not.
[G3 General] hyelton:
All the firmwares work as its an F400. But each firmware have there differences in bloat, settings, etc. Not sure one which one has the less bloat or the best though.
[G3 General] sebas_tytn2:
Where an I find the latest kdz for d855 Europe? (Netherlands)
[G3 General] hyelton:
There's no specific way other than using the LG link with your imei
[G3 General] sebas_tytn2:
Where can I find the link? All ready Flashed the one from your link (Europe V30b) but last update (stated in phone info) is from Dec 2015?

Other then that, the first method (lg flash tool + Kdz file) worked flawlessly. :good:

HELP!

[MENTION=2607037]hyelton[/MENTION]

My phone, when I hold down the volume button, says "Download mode disabled by kill switch". My LG G3 is a refurbished one but McAfee has locked me out of it. I'm trying to flash it, but I can't. I'm very aggravated and was hoping you would help me with this :D I also can't find the right KDZ file. I really need to fix my phone. I was hoping, if you will, to make the simplest guide for the stupidest person on how to fix my soft bricked phone. I think that's what it is, I can't get into it, but hte screen isn't black. It would be AMAZING if you did that. I'm in a frenzy over this
[G3 General] hyelton:
Does your phone boot into the OS? Sadly if that kill switch is there only way around it is to disable it in the app if your boots into the OS or change your motherboard.
[G3 General] Bican:
Any luck ?

I successfully restored img's and now my phone boots in DL mode.

However, i cant install a rom with DKZ or tot method. I kdz i get stuck at 4% and with tot it says model information check fail (i have all dll and tots and im 100% sure my model is d855 16gb.)

Any suggestions ?
[G3 General] LuninGaming:
I used rr 7.1.1 on a d850 and used get assistant (the app on play store)

Because this app changed the device name to pixel, i can't do this. It says wrong phone on the tool, and says S UD Pixel 07.1.1 Hrev_10 on my phone

Now i'm stuck in a recovery loop because i tried to update my recovery only to realize later that get assistant was to blame

when i power up the phone, it only goes to an ever loading screen of TWRP.

help please
[G3 General] hyelton:
So it never boots into TWRP at all? If it does flash a stock based rom if not you'll need to use a hex editor on the tot file to change the tot to exactly what was set for the model in the build prop
[G3 General] LuninGaming:
1) thank you for the reply :) :) :)

2)yes it doesn't boot into twrp after trying to update it, i believe its because of the edited phone name

2) yes flashing a stock tot and dll doesn't work because i have a edited phone name in build.prop.

4)so a hex editor, would cheatengine or np++ work? I'm sorry if i sound dumb but i have never converged with this side of android modding.

btw adb and fastboot do not work from any screen i can get it to, they all say device offline

---------- Post added at 02:25 AM ---------- Previous post was at 02:20 AM ----------

so i got a hex editor (the neo one)

so which strings do i edit do you know?
[G3 General] hyelton:
Google Tot method hex editor is about the best I can tell you there's plenty of links. I've never had to do it myself personally It basically involves changing the tot to be the same as what your build.prop model states.
[G3 General] LuninGaming:
sorry for the spam, i found the string with "d850" in it, any knowledge if this is the right string to edit? -> 1b5e318d80fe4afd85012e08198158b
[G3 General] hyelton:
Sorry no clue on the exact string but that sounds about right unless there's any other strings with D850 in them.
[G3 General] LuninGaming:
ok so i activated a 14 day trial so i can do a find all. also do you have to change the model on the dll aswell?
[G3 General] hyelton:
No you'd first try and use the normal DLL and if doesn't work you'd use the LGUP_8974 dll
[G3 General] LuninGaming:
welp i have no luck. There are thousands of 850's, hundreds of d850's and D850's, and there are many lg's and LG's. I legit have no clue where to starts, and google doesn't seem to know either :(

---------- Post added at 03:28 AM ---------- Previous post was at 02:55 AM ----------

when i try to flash the lgup dll with stock tot i get USER S0.0 AS0.0 B93 UHS S UD Pixel 07.1.1 Hrev_10 D85010d on my phone and

Change to dl mode

cant change to dl mode

[G3 General] hyelton:
Your placing the phone into download mode correct?? And your using a USB 2.0 port? USB 3.0. Will not work
[G3 General] LuninGaming:

well crap it seems that changing that does nothing...

I feel like when you change one thing on the .tot, no matter the .dll, it just doesnt work and it just doesnt go past bin.crc check and says failed previousload()

Hey, Would you be able to send me the exact same PM? I'm in the same boat (D852, need to return to stock, currently on CM13 with TWRP). Thanks!
[G3 General] hyelton:
Not sure why they sent a PM. Everything needed is in this guide. Except for since your on cm your best bet is to flash a stock based rom via twrp based on your model then follow this guide and flash it back to stock
[G3 General] DallasW:
Perfect thanks. So I'm going to flash to Fulmics and then use the 2015 TOT method, or the KDZ method? Any benefit using an older version kdz vs a MM 6.0 KDZ?
[G3 General] hyelton:
Don't flash Fulmics. That's not based on the D852 I don't think. Along with fulmics has modifications that causes issues. You'd want to flash a D852 specific stock based rom.

That's up to you what method you use. Preferably the tot method usually if it works for you.
[G3 General] DallasW:
Thanks for the help, found a Telus based stock rom, flashed that, used the KDZ method, and we're back to stock :good:

[G3 General] geokilla:

I already sold the phone. Kinda glad I'm done with LG phones (for now) as they are a pain to flash due to all their different versions and stuff.
[G3 General] rafk92:

[G3 General] hyelton:
What doesn't work on V30n? Model? Method? Your using LGUP and USB 2.0 right? USB 3.0 won't work. And V30 is MM which means you should be using LGUP ..
[G3 General] Gregory Ernest:
downgrading LG D850 from M - after searching threads, concluding that no LP .kdz file exists. So do I tell LGUP to look for the .tot file instead? Or am I missing something?
[G3 General] hyelton:
You use tot files for the AT&T model. You would have to flash The AT&T KitKat tot with lgup.
[G3 General] Gregory Ernest:
Great thanks!

Is that the .tot that lives in the BIN file at the top level of the AT&T directory?

Do I have to do anything specific with the LGFLASH .dll? Do I point LGUP to the BIN and call it good? I assume all other steps remain the same for the LGUP tool.

Final question: the .zip file (0 bytes) won't let me dl, sends up a server error - make my own? do I need it at all?
[G3 General] hyelton:
No you don't need the .dll file for LGUP. Just the zip.

Not sure what you mean? The zip file works fine at the top of the page. The 2nd link is just a mirror link.

Just have the phone turned on with USB debugging enabled and flash with lgup :)
[G3 General] Gregory Ernest:
Double checking that the KK .tot = filename LGD850AT-01-V10d-310-410-JUN-19-2014+0

Hey hyelton, thanks for the work you've done so far!

I've been trying to figure out how to use LGUP and .tot files to revert from Marshmallow to Lolipop since there is no root method for MM. I've downloaded D850_20F_Lollipop_Stock.zip from

//Xda/LG G3/Stock/AT&T D850/Lollipop/, but this does not contain .tot like I thought it would, does a lolipop tot not exist, or is there some way to convert a .zip to a .tot

Thanks again man

Lg g3 marshmallow upgrade - Boot loop issue

Dear Concern,

Thank you for your post about the 6.0 upgrade, very informative and useful.

With regards to the subject, I followed the steps to upgrade my lg g3 d855 with marshmallow 6.0 and successfully uprgaded. However, I am facing boot loop problem, my mobile is on if I use my mobile charger plugged in once i remove the charger pin my mobile goes off and restarts but only it display lg logo the first screen of boot and then repeats the same until i remove my battery and put it back.

I upgraded my phone with global.kdz file, my mobile made is in korea and I purchased in Dubai. I kindly request you to help me with this issue or advise me which .kdz file suits for my mobile, it will be much appreciated as I have not used my mobile since last 4 days.

Awaiting for your response, ASAP. Thank you so much again for your support and posts.

Have a wonderful day,

Rizwan

India.
[G3 General] hyelton:
Best bet is to try a factory reset first. Usually bootloop issues with the G3 are normally related to a battery problem.
[G3 General] hyelton:
That's a twrp file which I do need to remove due to confusion. The latest available tot file for the AT&T model is KitKat.

To get lollipop you'd have to OTA update to it with an AT&T or AT&T prepaid sim in the device.
[G3 General] cant_trump_the_stump:
Excellent, I was able to downgrade from MM to Kitkat using LGUP. For posterity, I was on a clean install of windows 10, usb 2.0 ports, LG driver version 4.2.0, and used LGUP & the dll in the OP (Post #3, versions 1_14_3 and 8974 respectively). Additionally, I had to put the phone into download mode in order for LGUP to recognize the phone.

Again, thanks for the great work hyelton! Do you take donations?

I'm glad it worked for you you're very welcome!. Yeah there's a donate button under my picture here if you wish to donate.

hi

my d855 can't flash kitkat to any stock rom (lollipop and marshmallow)

i tried with lg flash tool and lgup tool but still not upgrade

only 47% processes completed after that nothing should be there

so what should i do for upgrade my lg g3 d855

when i was upgrade kitkat to marshmallow flash 100% but still only lg logo nothing.

please help me i want to update to marshmallow
[G3 General] hyelton:
My flashtool will NOT work at all if the device was last running MM. You'll need to get LGUP to detect the device or use the old tot method and use a tot file to get it back working.

Also make sure your using a USB 2.0 port. USB 3.0 won't work.
[G3 General] mehulkarate:
my phone is working because i flash stock kitkat rom

but i want to upgrademy device to mm so how i do flash

i tried online method with lg mobile support tool but it was not update
[G3 General] hyelton:
Your post stated you couldn't flash KitKat so I'm confused?

You'd flash the same way as you flashed KitKat. Just flash a MM kdz file.

Lgup - unknown model (fulmics 6.5)

Hi everybody. I have some problem. I had used once this method and refurbuished my lg g3 then installed fulmics rom. Worked very good, But after some time i had to reset my phone but i did that unfortunately without twrp, with stock lg factory data reset and after this i lost root and when i wanted to try again downgrade g3 to lollipop LGUP did not recognize my phone model, showed as unknown. USB debugging mode also not workin as i thing, because when it worked it showed a little android icon on upper left side of the phone display, now it does not show. TWRP recovery also doesnt start. Do you know how can i fix this problem and use again lgup?

SORRY FOR BAD ENGLISH :/

Thanks.
[G3 General] hyelton:
You would need to use the old tot method. LGUP won't work with custom firmwares as it cannot detect the correct model.
[G3 General] emretutsak:
Thanks for information, friend ) I'll try it )
[G3 General] emretutsak:

I downloaded Europe D85530B_00_1217.kdz file and then following the isntruciont flashed it.

(in the instructions I quoted above is mentioned just kdz file not the tot)

I didn't downloaded the tot file because the instructions above say just the dz file and I don't know where to put the tot file in the suite

I flashed the kdz file and now I can boot only in TWRP no mater what I select into TWRP-Reboot menÃ¹.

[G3 General] hyelton:
You did choose refurbish on LgUp correct and not upgrade? The flash didn't go through as it would remove twrp.

Try using a tot file and flashing it with the older tot method. And make sure your using a USB 2.0 only port.

[G3 General] mikfaina:
For old method do you mean "2015 (updated with pictures) TOT Method!" In the First post?
[G3 General] cybercuate:
I have tried everything,normal installation on Win10, VMBox winXPSP3, universal drivers, LGUnited drivers, windows drivers, PCsuite drivers, USB 1.1, 2.0,3.0 (everything always as COM41) but everytime my D851 keeps appearing as "LGE AndroidNet USB serial port". As a result I can't use Flashtools (2015 method), it keeps telling me "Download FAIL (0 sec)" with the LGD851_20140611_LGFLASHv160.dll.

Just, Why?

BTW, it works with LGUP8974.dll
[G3 General] hyelton:
It's supposed to show LGE androidnet not sure what the issue with that was. It's a little different which each model or current software.

I'm glad using the other dll worked for you. Usually that's due to custom roms or build.prop changes
[G3 General] mikfaina:
What do you mean with the older method? Using Flsh tool 2014?

If I use Flash tools 2014 in the screen "Read phone information" I can't find my phone because I can enter just in twrp (and from there if I go Reboot->Bootloader in Download mode)
[G3 General] hyelton:
The tot method not flashtools 2014. And you never click read phone info you just click continue. You need to be in download mode. Other modes won't work.
[G3 General] mikfaina:
Another thing.

If I download LGD855 V10b-TWN-JUN-19-2014-32G.zip inside it there is the tot file named LGD855AT-00-V10b-TWN-XX-JUN-19-2014-32G+0.tot not the one without AT.

I think AT is for american operato AT son where I can find the tot right image (I'm in Europe)

In the flash tool i had the error model information check FAIl! (see attachment) but I'm in downloadmode I can reach it by holding volumeup while attaching usb cable
