There's no American operator called AT. There's AT&T but that's a completely different model number. The AT has nothing to do with a carrier in the file name. A D855 can be flashed with any D855 firmware.

You've changed the com port in device manager to com41 correct?? Your using a USB 2.0 port only right? USB 3.0 will give that same error and won't work. Also make sure your freshly putting the device into download mode with each try.

And try the lgup dll file.
[G3 General] mrhammad:
I tried going back to stock with tot method and kdz method but never worked out for me, however, I last time when I tried I did following things before the flash. I removed all the LG related drivers and reset all my com ports on pc by editing "regedit.exe" goto the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\COM Name Arbiter and on the right side set the value for ComDB=00 by editing it. I installed LG Driver 3.8.1 and tot files for KitKat and dll from LGUP_8994_DLL_Ver_0_0_3_23, and on the action tab instead of upgrade_dl I used board_dl. Everything goes well and installed the tot files, restart with Mini OS 3.0 from where I just hold the power button and click Normal + boot. I was back on KitKat. So I install LG PC Suite and leave my phone on did not go to download mode, just let the LG software update with the stock. First it update me from KitKat to Lollipop and then I had a chance if I don't want to update or proceed my update to Marshmallow and I chose to continue.

I think when we usb different usb ports this also give problem. So I am going to stick with one usb port, believe it or not it works for me.

I don't have black screen problem which I had on Nougat or other Marshmallow custom roms. So, I am gonna stick with stock.
[G3 General] mathsz:
Same here!

and yes they are....

I've settled on the g3. Got it for 120$. So I sold the iphone for a small fortune and can do anything I did before for a lot less of $.

Cheers!

Re

Is there any way to revert those buld.prop changes? I never did any root or installed a custom rom on this phone. I just have a problem with OFW 6.0 30d when a message pops up every time that "there is an overlay...", and wanted to get back and avoid this update until they got it fixed.
[G3 General] hyelton:
I thought you said that using the other DLL worked for you? If your not rooted then you never had any build.prop changes as you have to be rooted. The there is an overlay is usually down to a setting, I seen it when someone was trying to use Snapseed on a Galaxy S5 and changing a simple setting made the message go away.

I also went and reread your post you said you tried several usb ports, 1st if you tried a USB 1.1 port your computer sounds pretty old to be running Windows 10. also each time you change to a different USB port you have to go back and rechange the com port back to COM41 as each time it will change it.
[G3 General] cybercuate:
re

USB1.1 on Vmbox and also have some celeron D around with DDR1 256mb RAM. But yes it worked with the new .dll and I tried everything with the phone just flashed. I flashed some times by now and the first thing I do is open the gallery and it says it needs some permissions and the message appears. I deactivated/activated everything at the "control panel of permissions for overlays" or something like that and nothing. It is like a bug becuse i tried turning off/on every single app and open the gallery and it keeps showing "overlay detected".

Previous 30e didnt have that problem,30d "is" the problem, as far as I can guess at least for me.

Guess I'll get an android nokia this year
[G3 General] damjann4:
Pls can anyone help me ? Can you please write me what to download and what to do to go back from MM to KK i have d858hk 32gb dual sim model ?
[G3 General] alojo:
It doesn't appear LGEModem in PORTS :rolleyes:
[G3 General] hyelton:
Why quote the entire OP? [emoji19] it adds unnecessary clutter to the thread. It doesn't appear under ports because your device seems to be bricked. QHUSB means hard bricked.
[G3 General] alojo:
You are right, I was trying to express by the quote the method I used. I've corrected it.

But I can get into recovery and download mode. That wouldn't be a brick
[G3 General] hyelton:
Thanks :)

Seeing the QHSUSB in your device manager shows that it's a bricked/semi bricked device. Go check out the general section there's a guide that might help. It's call unbricking guide or something like that. It does require a little more effort but it's the only way to possibly fix that.

Catastrophe

I attempted to downgrade my MM d850 LG G3 to kitkat using LGFlashTool, and it got to the second level before saying USB Closure or an error like that. The device manager in Windows 10 now does not show Ports so I can't get LGFlashTool to find my LG G3, and now I cannot get my phone to go to firmware update-- It goes straight to Level 2 and I have to take the battery out. If I am able to get the FlashTool to work again I would choose Board DL, but I cannot get to that point. Any help?
[G3 General] hyelton:
Goes to level 2? You mean number 2? And yes using board DL will fix that.

Did you make sure your ports are unhidden? By default in Windows 10 the ports are hidden. (Unless it's not showing up due to not being in download mode)

The com port won't come up unless your placing the phone into download mode which you have to place the phone in first before being able to do anything.

Also next time when downgrading from MM remember always use LGUP it's a lot more simple and sometimes the only way to downgrade from MM.
[G3 General] l0rdbyr0n:
I am not able to go into download mode, it goes straight to number 2. Am I screwed? :(
[G3 General] cukaasha:
Why do u even want to downgrade to KK? Is MM that bad for your G3?
[G3 General] hyelton:
I'm sure it will go into download mode. Your using the correct button combo while plugging in the USB cable connected to a USB 2.0 port while the phone is off correct? A charger or USB 3.0 won't work.
[G3 General] l0rdbyr0n:
I was able to get it to download mode using this same cable and port previously. The second the battery is put in the phone goes to Mini OS and then Level 2. The only way to turn it off from there is removing the battery. I do volume up, but I've tried pretty much every combination.
[G3 General] hyelton:
So when it's completely off after putting the batter back in. Holding volup at the same time While plugging in the cable right?

That has never once failed to work unless there's a worse issue involved somewhere.
[G3 General] l0rdbyr0n:
I am actually able to see the download mode for a split second when doing that, I can barely tell it's there. Then it shows the LG Logo, Mini OS, and then Level 2. What I do exactly is this: Have phone plugged in connected to computer while holding volume up, then putting battery back in.

---------- Post added at 11:40 PM ---------- Previous post was at 11:37 PM ----------

I switched the cord and usb port I was using and I'm now in download mode. Odd since I've been using the same cord and port the whole time. But not device manager is not showing ports so I can't set it to the correct port for LGFlashTool. :/
[G3 General] hyelton:
If your running Windows 10 you may need to unhide the com ports. Glad you got it into download mode. Is the USB port your using USB 3.0? As sometimes I won't even get detected with a USB 3.0 port.
[G3 General] l0rdbyr0n:
I reinstalled the drivers and now my G3 isn't bricked and is rooted. Thanks for all the help, now to install a custom ROM if I can figure that out... Do you recommend any? I was looking at crDroid Nougat.

my phone model g3 d855 16 gig

android 6 v30e

no downgrade

plz help

Is there another way?

error kdz & tot
[G3 General] hyelton:
What do you mean no downgrade? Explain? The D855 can be downgraded most likely.. what error?
[G3 General] dirtfoot:
Good day all. I'm trying to fix my friend's att lg 850. It was on Android 6.0 so tried to follow Post Number 3 downgrade it to start fresh but it just bootloops now. I factory reset it as well. What's the exact file I should be using in lgup?

Sent from my VS985 4G
[G3 General] hyelton:
What file did you use? There's only 1 tot file for that model that you can flash. You had choose referbish correct?
[G3 General] dirtfoot:
Thanks for the quick reply. I'm not home right now so I'm not certain which file I used but I got it from the storage cow site under lg g3 stock AT&T d850. But I don't know that it was a tot file. Does it need to be unzipped a certain way? I don't want to be one of those persons but any chance you could point me to the file.

Sent from my VS985 4G
[G3 General] hyelton:
There's only 1 file that can be flashed for the the D850. It's a zip file, and you extract it and you get a tot file. It's in the exact folder. I was just making sure your flashing the right model, you'd be surprised.
[G3 General] dirtfoot:
Thanks again. I flashed the v10d tot. So I guess it's the correct file. I'll flash again but perhaps it's hardware. The phone had been acting up, freezing and rebooting frequently among other issues. 6.0 can still be downgraded correct? There wasn't some recent update that ended that I hope.

Sent from my VS985 4G
[G3 General] hyelton:
At the current time yes. If there was antirollback lgup would had stopped it.
[G3 General] hyelton:
Yes you can. Only reason that people have bootloop is when they don't reset after flashing mostly.

so is it possible to make my tmobile g3 into a unlock g3.

I had a att branded htc one and i made it into the unlocked version . im wondering if i could do the same with the g3
[G3 General] hyelton:
You mean carrier unlocked? Or unbranded firmware?
[G3 General] YourWorstFears:
i mean unbranded firmware
[G3 General] hyelton:
Best thing for that would be just run a custom Rom. Other firmwares can be flashed but its risky and not easy.
[G3 General] YourWorstFears:
is there a rom that you recommend me to use?
[G3 General] 1aggelos1:
I tried to do it with option 1 and failed. I have installed all drivers. Anxone had the same problem?
[G3 General] 1aggelos1:
is it ok for example if instead of German V10 I put open european ? whats the difference? (I live in Germany )
[G3 General] hyelton:
What problems? You have to explain. There's several things I can be. Is the phone in Download mode ? Did you download the kdz using a download manager?
[G3 General] 1aggelos1:
oh man I noticed before 5 mins that the file is smaller than the original , so i guess smth went wrong with the download and the file wasnt complete ! pffff. i will redownload it . Do you have any clues about the question I asked above?

thanks
[G3 General] hyelton:
It should be fine to flash a European just make sure its for the same exact model D855 for example. But why would you want to? There's really no difference.
[G3 General] Osama Alaa:
it's a new feature added after flashing d85510n kdz

Dude..:SAVE ME. LGUP and Flash Tools 2014 every time i start the flash...CRASH during the extraction phase.

Tried everything like :

-clean uninstall and install

-changed usb port

-run as administrator...

I use Win10 i have to do a rool back from v30n to v30b because otherway i can't do the root (It seems that 30b version is the only version fo do a root with autorec e kingroot metod), but LGUP and Flash Tools crash everytime... I wanted to try a TOT installation with LGFlashTool2016 but i can't find a right TOT for my version, i've founded only your TOT file, but is AT provider... i dont wanna risk a brick...specially with LGUP and Lg Flash Tools 2014 that doesn't work.

I've tried also to download different KDZ files and:

- with the Global and Europe version of v30b LGUP and Lg Flash Tools 2014 crash

- with another KDZ version (D85530B_00_1217.kdz) the software say that is unable to extract the software or connect to the server (what f###ing server?!?!?I dunnow...)...

PLEASE HELP ME, i'm desperate, the device is for my girlfriend, i need root for try some custom rom or first of all kill app and greenfy them (battery drain problem...), but with my 30n version i can't root the device...
[G3 General] hyelton:
First of all your missing a few things... 1. What's your model? I'm guessing you have a D855 right? There's a D855 TOT file in the OP... there's no such thing as an "AT" provider that's just part of the file name for that tot.

Now you cannot use LG flashtools kdz method if you where running MM it WONT work and it's not supposed to work at all, also connection to server failed is supposed to pop up you drag the window out of the way this has been explained many of times. But also been explained that the method won't work if your running MM.

You can ONLY use lgup or TOT method flashtools.

Now what error are you getting with LgUP? What do you mean by crash? If it's freezing make sure you downloaded the the kdz file or tot file using a download manager to rule out a corrupt download. Make sure your also only using a USB 2.0 port USB 3.0 won't work. If lgup continues to freeze/crash sounds like an issue with your computer, I've never had lgup crash the hundreds of times I've used it.
[G3 General] zolloz:
Hi which version should i use if i have cm14.1 on my g3, tot or kdz? or does even kdz work any longer with android 6.0+? besides i have a D855
[G3 General] hyelton:
You will first want to flash a stock based rom like a debloated rom etc based on your model. It will make sure you won't have any issues as CM can cause issues with detection in flashtool. Then flash what version kdz you'd like as long as it matches your model.
[G3 General] EasyCake:
Hello everybody.

i have an issue with my friends LG G3, D855. I'm trying to restore it to the factory (stock) firmware, but apparently I always end up in the boot loop, either when trying with KDZ, same results in TOT method. I'm no longer sure what can I do, can you please help me?
[G3 General] hyelton:
It's fully flashing right? What was the reason you needed to restore it back to factory stock? Did you try choosing board_dl on the tot method?
[G3 General] EasyCake:
Using KDZ first time, it fully flashed, after second and on other attempts it just shows error and asks to retry connecting the phone. The reason was that after updating to 5.0 battery was draining very fast, wifi and bluetooth was constantly trying to find anything with no luck. Tried choosing board_dl as well, after numerous tries once reached AAT, but thats all.
[G3 General] hyelton:
Unless you can get it flashed and it boot it could be a battery issue which seems common with the G3. Can't say for sure that it is but it happens
[G3 General] EasyCake:
Okay, got it. Will try to flash it once I'll get new battery :)
[G3 General] notinthemood:
what method do I use if I want to downgrade my f460k to lollipop?
[G3 General] hyelton:
Lgup if your running MM
[G3 General] Usmanashad:
Lg g3 vs985 mm6.0 to stock

My lg g3 was already upgraded to 6.0 marshmallow when i bought it in used condition. However neither kdz nor tot method seems to work to downgrade back to stock.

While kdz method says the phone z not connected to the pc and tot method via com41 show pid and imei as null. Also it says its unable to read the phone's software info.

Can someone help.?

Regards

Usman
[G3 General] hyelton:
That's because you use LGUP to flash tot or kdz files.
[G3 General] Usmanashad:
I used lg flash tool not the up tool,..

I dont know wats LGUP
[G3 General] hyelton:
Lgup part of this guide. As stated in the guide if your running MM you must use LGUP.
[G3 General] talexandros:
Can someone please help me my phone was removed at 94% because of usb cable problem

and now factory reset is on number 2 every time i boot my phone and i cant do any think from download mod they say me conection fault cant change to download mode﻿
[G3 General] hyelton:
Are you the same user from YouTube comments by any chance? I responded to your last comment if that's you.

If not unplugging at 94% had nothing to do with your issue as anything after 80% it's done flashing you can unplug anyways.

You need to reflash using board_dl.

Make sure your freshly putting the phone into download mode, using a USB 2.0 only port (USB 3.0 won't work and will cause that exact error) and you've made sure to check your com port is still com41 as it does change sometimes
[G3 General] notinthemood:
Thanks! Used method in post #3 and it worked smoothly!
[G3 General] coolmanas2010:
Hello, My phone isn't detected by LGUP (Shows unknown model number), LG Flash Tool 2014 (.tot and. Dil method) stuck on a error "system partition factory...... ".

I earlier had Fulmics Rom installed with the help of TWRP.

Phone is stuck on download mode. It automatically boots in download mode. After LG logo it every time boots in download mode until Vol Down and power key are held together then it boots into Stock LG recovery. Is it Bricked?
[G3 General] migokgta:
Hi, that problem is because LGUP can't read the kernel of Fulmics ROM, you need first flash another ROM like https://xdaforums.com/lg-g3/development/zoe-rom-v1-0-mm-6-0-stock-v30a-d855-t3402087

and then use LGUP

Regards
[G3 General] coolmanas2010:
Hello, but how do I flash another rom? As I stated I'm stuck on Download mode and what tool should I use to install custom rom like this?
[G3 General] hyelton:
Recovery if you still have it. If not follow the tot method guide and choose board_dl
[G3 General] coolmanas2010:
No I don't have it.. System recovery. So following up the same steps with board_dll.

Will tell you the results. Or any error i catch on way!
[G3 General] coolmanas2010:
As I mentioned I got the error stating

"## [ERROR] : Partition Change factory Partition (Phone!=tot)"

Here is the log file.

Thanks for the suggestions.
[G3 General] my.ads0:
If you can get to the Factory Reset screen, then do a wipe from there. That should bump you directly into TWRP.
[G3 General] coolmanas2010:
No i again bumped into download mode it didn't went into twrp.
[G3 General] Usmanashad:
Hi there,

Im having the following error as shown in pic. Could someone help me please..
[G3 General] hyelton:
Using a USB 2.0 port correct? USB 3.0 won't work and can cause that error. Freshly booted into download mode each try? Try a different USB cable? Make sure the correct com port is set in device manager?
[G3 General] my.ads0:
I couldn't TOT from XDABBEB's 3.1.1 ROM. I HAD to use KDZ.
[G3 General] Usmanashad:
I dont knw abt 2.0 or 3.0, i just use windows 7 thats all i knw. However i'll check it tomorrow. And i freshly booted to firmware upgrade or download mode beforeevery try. And port is surely set to com41.

I am actually trying to downgrade from 47A thats marshmallow 6.0 which is not supported i believe. Any clarifications will be welcome
[G3 General] hyelton:
You just only Use usb 2.0. Usb 3.0 won't work so it's important to check...

Downgrading from MM is iffy with the old tot method but does sometimes work. Otherwise you need to use LGUP.
[G3 General] Usmanashad:
Can u guide the link to LGUP method??
[G3 General] meatpuppet007:
Quick ? I have a vs985 on 4aa update if I factory reset after cache wipe from recovery mode will it go back to 5.1.1 factory?
[G3 General] hyelton:
What do you mean? It's on the first page of this thread..
[G3 General] hyelton:
No it will reset the device not android version it's like this with every android device. You would have to flash the firmware to downgrade.
[G3 General] meatpuppet007:
Well that's. A waist cause all methods I've tried won't downgrade since 46a
[G3 General] hyelton:
That's a carrier device so it's to be expected to happen at some point sadly
[G3 General] meatpuppet007:
Any recommendations for bootable replacement 4 my vs985?
[G3 General] hyelton:
Bootable replacement?
[G3 General] Usmanashad:
The first page quotes To Downgrade/upgrade to/from MM 6.0 You'll need to use LGUP in Post #3 Currently only for the D855

While i have vs 985
[G3 General] coolmanas2010:
Yeah I too have a vs 985.. And I'm also having difficulty in model recognition. I too am trying to downgrade from MM. What ROM you flashed?
[G3 General] meatpuppet007:
Rootable
[G3 General] hyelton:
LGUP works for every model not just the D855. I haven't fixed that post yet.
[G3 General] hyelton:
If your having model recognition problems you need to flash a rom based on your model number that's not modified
[G3 General] coolmanas2010:
It shows D855 as model number! So can you please help me with the right rom without any modifications.. VS985 .tot and. DLL didn't work. D855 one goes till 6% then shows error. Can you help me with right. Tot please?
[G3 General] hyelton:
The VS985 tot and dll work perfectly fine.

Why did you attempt to flash a 855 Firmware?! That may have ruined your phone.. you can't do that. Hopefully it didn't cause you to loose your EFS which will turn it into a wifi only device so hopefully nothing went through.

Do you still have TWRP? That's the only way of flashing a stock based rom to fix the model issue.

Since you have a VS985 why not try the kdz method??
[G3 General] coolmanas2010:
I think I lost EFS.. I don't have TWRP.. System recovery shows up.. My model now shows D855 cause I earlier flashed D855 MM Fulmics.
[G3 General] mfelipe:
In case it happens to anyone: I have an euro D855 with 30n and LGUP was showing the "Unknown device" error. I had installed the OP LGUP but no dice.

So I tried to install the 8974 version of the DLL and it worked!

In case anyone need it: https://mega.nz/#!VhpDxKoI!Mo0LcQOVOjcM337Vs2X87KoEMvE3HApYgpFNMYEl4XU
[G3 General] hyelton:
You won't know if you lost your EFS until you get your phone running again as you'd no longer get service. Why not attempt to flash and use the kdz method?
[G3 General] hyelton:
That file should already be included in the zipped LGUP download in the OP. If it's not all add it
[G3 General] mfelipe:
That was stupid, I'm sorry: I mixed up the 8974 and the 8994 DLL!!

Again, sorry!
[G3 General] hyelton:
Is the 8994 not in there? If not I'll update it and thanks!
[G3 General] mfelipe:
Only 8974 is in the LGUP_LG_G3.zip
[G3 General] johnny_cage:
Hi mfelipe, did you try it for go back to lollipop? It worked?
[G3 General] hyelton:
There's no reason why he D855 can't go back to LP. Remember it's usually only US carrier models that cannot downgrade at times.
[G3 General] Sibirc:
