Your for sure using USB 2.0? And you've set the correct com port in device manager to com41?
[G3 General] zzricezz:
just tried it on my laptop and same error. so it not a usb 2.0 thing, and yes it is set to com41 and the phone upgrade firmware screen indicate it connected using com41.
[G3 General] hyelton:
What do you mean by screen indicate com41? Also in device manager?? Flash tool will show com41 no matter what even if there's no phone present...:

Common LG G3 Issue

Hey there, I just read your post. My phone developed the same problem. I researched a fix for months with little luck. It seems to be a problem with this model of LG, and the company won't do anything to fix it, they deny it even exists. Basically your perfectly fine screen will randomly fade to darkness, sometimes just black and sometimes with lines. Pressing power button off and on again will make it come back to life, but then it will do this again and over time it degrades and becomes more frequent. My advice is to not waste time trying all the methods to fix it that are proposed online, which include baking the motherboard in an oven and jamming bits of paper or pieces of cut up credit card on certain points by wires on the board. These fixes only work temporarily. Save all the data and get yourself a new phone, cos it cannot be fixed. Also, if you have a chance while the screen still works, you can install software on the phone which allows you to operate the device via your computer screen. Then when it goes black and refuses to open, you can still navigate and use it. There is nothing else wrong with the phone.. in theory you could leave it connected to your PC as a storage and gaming device, but as a phone it will only continue to let you down until it is no longer usable.
[G3 General] xpmule:
I can confirm it is still working for me as i said earlier with my D852 LG G3 from Telus (Canada)

I downgraded (from MM) then rooted it and put on TWRP and then upgraded to Marshmallow.

Only issue i noticed is i have to pull the battery or it won't turn on.. *if i shut it off.

I heard of others with that problem too.. but oh well what ever.

I followed Henry's guide which directed me to this topic.

Thanks to Henry and the OP here.
[G3 General] Lanikor:
Temporary (can last for minutes or months) solution is to open the phone, put a small coin on the spot which is in front of the processor and then closing it. You may have to align it from time to time, but additional pressure will reduce or remove flickering and/or fade to black problem. I tested it on another G3 and it was working. For how long and will it work for everybody, i can't tell.
[G3 General] jlb1959.01:
and the cause for this problem is???.

I've had it happen to the wife's vs985,non rooted..just replaced the mother board but never knew there was a problem with others as well.
[G3 General] hyelton:
Overheating/design flaw/hardware problems. Lot worse on the G4/V10 which was finally fixed for the G5
[G3 General] jlb1959.01:
Dang,,I thought my rooted vs985 was caused by flashing etc,but then the non rooted died same way..good to know,kinda like the vs985 always seemed easier to root,almost indestructible with ways to flash back to stock etc,but I've had troubles with sim also over the years.thanks for the info..
[G3 General] Lanikor:
Also LG Nexus 5X and sometimes Huawei 6P experience similar issues. Especially Nexus 5X, those are dying like crazy because of the design flaw which is pretty much narrowed to bad soldering process and reballing usually helps only a little bit or it doesn't help at all. LG made serious mistakes on those devices, they were very good while they were working but excessive heat kills them all eventually because soldering becomes loose.
[G3 General] xpmule:
You guys are pretty bad with going off-topic.

And if you know how solder works you'd know heat from the phone should have no impact.

It would have to be heated high enough for the solder to melt and break free.

Not gonna happen..

I would wager the problem is more likely stress from jarring or banging it around or minor flex or bending over the years that eventually break the solder connection.

I google'd it and it says..

"Alloys commonly used for electrical soldering are 60/40 Sn-Pb, which melts at 188 °C (370 °F)"

If your phone is hitting 370 Fahrenheit i think you would be complaining about more than a faulty phone LOL

Anyway..

I came back to see about the topic.. you know the point of the topic hahahah

I have to pull the battery out of my phone if i shut it off after following this guide.

In case you don't get it.. that is a HUGE pain :(

So.. i came back here to see if there as any talk about the problem.. not yet another topic discussing hardware problems which seems to be the common theme on every topic in this forum sub-section.
[G3 General] jlb1959.01:
Lol, an inconvience to pull the battery after tot to stock??
[G3 General] xpmule:
Yes pulling the battery out is a problem.

Luckily i figured that out on my own or i would have a brick.

So to the people who read my post and LEARNED something ..you are welcome ;)

And yeah you guys are REALLY bad at making off-topic garbage posts completly unrelated to the topic.

It's frustrating at XDA when people seem to wander around posting anything anywhere.

You wind up in need of info but unable to find it.

LOL, common sense much ?
[G3 General] jlb1959.01:
1st-- I asked a question to OP as why I had an issue with the vs985,that wasn't going off topic,so if you were talking about me,go back and read the post of mine..

2nd.. there is a video from Laserwolf showing exactly how to kdz to stock(giving thanks to many people including road warrior and OP),and in the video it shows step by step as to what to do with kdz,no need to pull a battery on kdz,ONLY with tot!!!!!!!!!!!
[G3 General] jlb1959.01:
not to advities on this forum,but laserwolf has a utube channel to go along with being a major contributor,see attach pics of 2 videos of which he gives thanks to OP,and in it gives a step by step instruction of kdz on vs985,,

and never told anyone to pull the battery,
[G3 General] hyelton:
Depends on when to pull the battery? Some who may not be able to boot into an os may need to pull the battery to freshly put the device into download mode.
[G3 General] jlb1959.01:
agree,I meant at the end,I guess that's what the person was trying to say about pulling battery and bricking,I believe meaning pulling battery after kdz is successful??. point was the instruction with kdz are right on,and once in process there's no comments to pull battery.

---------- Post added at 10:10 PM ---------- Previous post was at 10:07 PM ----------

that's what I meant,sorry for improper wording,person stated luckily they didn't pull battery and brick,guessing that means after a successful flash?..
[G3 General] xpmule:
I followed the instructions fine.

I used Henry's guide and got the correct files.

His guide says follow the topic here.

Now..

Anytime i power off i have to pull the battery out or it won't go back on.

Henry commented and didn't know what to say.

It's worth mentioning which is why i did.

I also brought up the never ending off-topic rambling by users here because it's pretty bad.

Now i have said all that probably 6 times between the two topics. LOL

I am wasting my time.

And i can follow simple instructions with out noob youtube videos ahahhaha

I have a rather interesting history with PC's and phones etc.

My resume is monolithic.

I am the only guy who ever "cracked" a line of LG phones a decade ago and coded programs so others could have unlocked content on their phones for free.

Call it a jailbreak or what ever but it took me a couple months and i got it done when i quote "it was impossible"

Then i used c++ to write GUI app's to let all of you do it too. (posted on Howard Forums)

I am a rather notorious "cracker" / coder.

My resume is loooooooooong.. so yeah.. i followed the simple instructions and best i can tell i made no mistakes.

I posted my story to inform others who may have the same phone and who also might end up with the same problem.

I am not too comfortable having to leave my phone on all the time wasting battery power.

But it's either that or pop the cover off..

If i keep doing that then it's going to eventually wear out the cover clips that hold it.

Anyway..

No one has any idea what happened so i have given up.

So never mind guys just carry on.

I usually don't waste my time asking for help.

I can usually get it figured out before someone can reply.

Like the OP here.

He looked at my first comment on this topic and the EDIT i added then repeated back to me WHAT I SAID hahahha

In other words he gave me the advice i posted before he did LOL

He posted well AFTER the edit i made.

I am wasting my time here.

I usually don't expect much from people on this forum.

I will figure it out.. the question is will i bother to post the solution ?
[G3 General] Xplorer4x4:
I have a D851 and tried the KDZ method because I could not see my device as a serial port connections in device managerWin10) to try the tot method. So I reboot to download mode, connect USB, open LG Flash Tool 2004 as admin, select KDZ file and hit CSE Flash. I hit start on the next screen. Start on the screen after asking country and language. At about 50% I got a pop up with a bunch of question marks, but I noticed the progress window still climbed to 64%. At 64% it seemed to stall out so I took a gamble and clicked one of the pink boxes in this pop up. I guess I clicked the cancel button as the flash progress window disappeared completely. I tried to relaunch LG Flash Tool 2014, but the progress window would appear as before but says the phone is disconnected from the PC. I tried rebooting both the phone and the pc but no matter what LG Flash Tool 2014 refuses to see my phone. I have tried 3 different usb cables with no luck either. Any idea how to get Flash Tool 2014 to see my device again or how to get my phone to show up as a port in Win 10 to try the tot method?
[G3 General] hyelton:
You will need to place the phone back into download mode for the computer to detect it. Are you doing that?
[G3 General] Xplorer4x4:
Sorry that was not clear. Yes, I had rebooted the phone in to downloader mode. I did it through advanced restart menu in crdroid though. For some reason I can not get the phone to boot in to downloader mode by holding the volume up and power button. I aslo tried holding them, releasing them when the LG logo shows, and then repush and hold power but the phone always boots in to crdroid(Even as we speak).
[G3 General] jlb1959.01:
didn't mean to offend you,just pointed out that both those people are contributors to xda and have a few forums with people trying to kdz with lg3..neither of those two are newbees(although road warrior forum is mainly dealing with vs985,he is a knowledgeable man as is laserwolf) to lg3..hope you find the solution mate..

Method for Lg g4 ?

Do you have same method for LG G4 T-mobile H811 ? If yes please send me its link.​
[G3 General] hyelton:
There’s a G4 back to stock guide in the G4 section. You would use lgup. The methods are all the same.

But remember since you have a T-Mobile G4 there is antirollback if your wanting to downgrade.
[G3 General] sulphar:
Thanks, Can you share Stock Images .tot method or kdz files? or link?
[G3 General] Xplorer4x4:
Yes I made sure the phone was back in download mode. This is the same as choosing bootloader when rebooting the rom right? I can't seem to access it using the volume up + power button method.
[G3 General] hyelton:
There all in the OP links for all models :)

Help Please

I trying to downgrade my d855 from MM to LOLLIPOP and in LGUP I don't have a option to add .kdz file, only .tot, why?

Can someone help me please?
[G3 General] Xplorer4x4:
I tried a 4th USB cable and my phone showed up as a serial port and I was able to proceed with the tot method! Everything went as described in the OP. Thanks for the guide and the app!
[G3 General] hyelton:
Choose upgrade, select the kdz, go back and choose referbish and it should be there.
[G3 General] Lidor167:

[G3 General] SyCoREAPER:
[MENTION=2607037]hyelton[/MENTION]

Could you please clarify for D850 running MM... Follow Step 2 or 3? You have conflicting information..

This thread still only lists D855 for LGUP
[G3 General] hyelton:
LGUP works with every model of LG phone. Only reason it originally stated that as it just wouldn’t detect the phone before.

Sorry about that I swear I had removed that long ago.
[G3 General] SyCoREAPER:
One last question, slightly OT, what I am trying to do ultimately is get TWRP on the device but it's been years since I did it and it was on a vs985 but am now doing (and trying not to brick) my fiance's D850.

Can I root and TWRP from LP or do I TOT down to KK after Lgup?
[G3 General] hyelton:
I haven’t kept up with the G3 root wise (only really keep up with stock) as I haven’t owned the device since 2014. But I would think you would need to downgrade to kitkat there should be some root threads in the general section.

With the G2 I know you have to downgrade to kitkat for root.
[G3 General] SyCoREAPER:
Thanks again, I guess one last question if you know, (promise). Does Lgup have to use the image provided (which I think the d850 is LP) or can I use a KK variant Link?
[G3 General] hyelton:
I don’t understand what you mean. You can flash whatever tot file as long as it’s for your model.

Also you only really have to use LGUP if your running MM or newer. You can still use the old tot flashtool if your running LP.

Also that link you posted, looks like a lot of there LG files where taken from my server which there’s links to in the OP in case you have problems downloading from that site lol (I couldn’t even get anything to download from that site it would take me to a page with just Advertisements with no download lol
[G3 General] SyCoREAPER:
I realized after I posted.

So basically my question is, does LGUP care what tot is used? Can I jump (using LGUP) from MM --> KK or do I have to go MM --> LP --> KK

I'm derp derp derp derp. I misread the file name on your server. Yours is KK, I to be honest assumed it was LP since the instructions said downgrade from MM to LP.
[G3 General] hyelton:
You can jump, you don’t have to go file by file kitkat is the only file available anyway for the D850. Also all needed including the tot files are in the OP
[G3 General] SyCoREAPER:
Thanks, I edited my post while you happened to be replying. I am a complete derp :eek::eek::eek::eek:. Your file is KK which is exactly what I wanted, I had assumed it was LP. This is what happens when I become hyper focused on something and miss the obvious.

Thank you for all your help.
[G3 General] hyelton:
Haha , yeah was a little confused if maybe the links somehow wasn’t working correctly lol. Yeah nothing newer than kitkat ever sadly. If you ever want to go back to stock only way to get back to LP or newer you have to have an att sim and ota update.
[G3 General] SyCoREAPER:
KK is exactly what I need, just trying to get TWRP on the phone and from there I can work my magic. Been spoiled with my phone having an unlocked bootloader :)

Thank again and keep up the great work.
[G3 General] kingsmaster:
Hi.

I flashed my f400l using lg up method rom marshmallow to kitkat. after restarting i was stuck on mcafee lock screen and my download mode was blocked with kill switch. thanks to xda i manage to open download mod and flash again stock rom but now i have no recovery installed because when i was on marshmallow i had also no recovery but when i was on kitkat my phones boot into recovery but now again same problem. i downloaded tot and dll files from cowstorage. i dont like stock roms and stock recovery i need a custom recovery to run a custom rom. kindly help me. that if i again downgrade my f400l from lollipop to kitkat will it again comes with kill switch? now i am on stock running rooted lollipop and properly rooted. but not booting into recovery i used adb to boot into recovery but only there was a android with a yellow sign. please help me to install stock recovery so i can use key combinations to boot into recovery. Thanks in advance.
[G3 General] hyelton:
Sorry this thread is mainly for flashing STOCK firmware. Someone here maybe able to help but I this thread is only geared towards flashing stock firmware.

Depends on how the kill switch was removed not sure if it will come back. If it was removed the legit way it won’t come back, but by methods here no clue.

Lg g3 D850

Getting error of Milkyway connection.

Cannot flash through tot method.
[G3 General] hyelton:
Huh? MilkyWay connection? I don’t know what that is. That doesn’t sound right. Got a screenshot?

Your device in download mode? Your using usb 2.0 port? ( usb 3.0 won’t work). Using a oem LG usb cable?

Where do you see the error? What’s the reason your needing to flash your device?
[G3 General] uxairmalik:
Yes phone is in download mode.

Usb 2.0 port.

Oem cable.

I have done it before on several devices so i am familiar with the process.

I am running win 10 machine.

Problem occurs when i open lg flash tool.

Before even i could add dll and tot location error pops up saying milkyway connection error.

I press oK and the process continues but the status stays at waiting for connection.

It doesn't connects even after removing cable for many times.

On usb 2.0 in download mode at com 41.

It works without any issue on my friends win 8 machine.

Before it was working on mine too.

Screenshots
[G3 General] hyelton:
Looks to be a specific issue with your computer your doing this on. Did you remove and reinstall flash tool? Since you said it works fine on your friends computer.
[G3 General] uxairmalik:
Yeah i installed it several times.

Even installed windows again.

It was working before but i dont know what happened.

I will downgrade to win 8.1 and than will check again.
[G3 General] billyboy2316:
Could you tell me how to make COM41 port stay open? I get to factory reset 2 and the port is closed and won't open.

Thank you
[G3 General] hyelton:
Open? If it’s closed that means it’s being used.

But if your getting factory reset 2 you need to reflash choosing board_dl
[G3 General] drich290195:
Hi guys I seem to be hitting a problem. I have a d855 uk version of he g3 branded to Vodafone uk.

No matter which rom I install it will always stay the same branded version. For example if i flash euro 10A it will become a Vodafone version of 10A not the generic euro version. I have tried uK specific kdz and euro ones, even tot files the same thing happens it will downgrade to the version of my carrier specific rom.

I don't know what else to do it flashes ok just never makes it stock with no carrier branding. Any ideas. Thanks guys.
[G3 General] hyelton:
Are you performing a reset before and after flashing?
[G3 General] defens23:
I installed the LG drivers and tried to connect my phone. Kept getting an MTP install loop. Obviously this will not work with XP. Going to upgrade to Windows 7 hopefully this weekend and try again.
[G3 General] hyelton:
Was the phone in download mode?
[G3 General] defens23:
No. I don't know how to put it in that mode. Some assistance would be great. I also noticed that USB debugging turns off when I plug the usb cord into my laptop. Normal? Sorry for all the questions. Didn't have these issues with the gnex.

Edit: Got it. Looked it up on youtube.
[G3 General] hyelton:
You HAVE to be in download mode to flash, its in the OP. YouTube it or Google it the must simple way to put it.
[G3 General] defens23:
Helpful youtube on how to use the TOT method as you described in the OP. I'll give it a try tonight when I get home. Thanks.

Guys i need help. I just want to know if the kdz files in the picture are for 32gb g3? TIA
[G3 General] hyelton:
For the G3 16gb and 32gb are interchangable.
[G3 General] jharone23:
Coz i see some thread that it says you can flash the ones for 32gb kdz to a 16gb g3 but you cant flash 16gb kdz to a 32gb g3
[G3 General] hyelton:
Yes for the G3
[G3 General] bobsie41:
All of the branding stuff is stored by your device in the data/OP folder which is not touched by a kdz.

If you root first, delete the data/OP folder then flash a kdz, your branding will be gone forever. ;)
[G3 General] alandd86:
guys if i flash latest 20d will i still get ota updates in future ?
[G3 General] jharone23:
Sorry kinda confused.. What do you mean by interchangeable and can you please tell me how to see or know that its for the 32gb kdz file
[G3 General] hyelton:
With the G3 just flash the correct model number. Size doesn't matter.

Messed up returning to stock

Hi all,

I hope I'm putting this in the right place. I've had my phone, a Sprint LG G3 (LS990), for about 2 months. About 6 weeks ago I decided to root it and it worked with Stump Root. I also installed TWRP 2.8.0.0 and had no issues. On Monday, I had an OTA and thought that I had to return to stock to install it. I'm going to blame on weak thought processes. I found about 8 different ways of doing it, but the deeper I went the deeper I sank. I can start my phone, but it goes straight to the TeamWin logo/screen. I wiped, restored, and just about anything else you can do to mess up a phone (I know, next time ask for help). Anyhow, it appears that most of the TeamWin buttons work, but when I look into the backup option, it shows 25,131 Mb available, which doesn't leave a whole lot of room for an OS to exist. I hope I'm wrong. I do have a microSD card and adapter, so I can write files to the microSD. Is it possible to load an image or other software/processes to the microSD card and then either copy it to the phone or a way of flashing it to the phone. Can anybody either point me in the right direction to do this or step by step instructions to fix it? I'm fairly PC literate and am trying to learn android, but right now I'm stumped and I worked on this all day Monday, after work yesterday, and who knows how long now.

Thanks,

Pat
[G3 General] hyelton:
You'll most likely need to flash back to stock using this method. But you must use a PC
