[G3 General] jas777:

i cant find the stock rom to my d855 32gb [i see only 16gb],

my phone won't boot, and i need the stock rom to fix him,

which firmware file, is the suitable for me?

thk
[G3 General] hyelton:
LOL, Wow I havent seen that in awhile usually its just a wrong model but not an entirely different brand/phone lol.

Anyway heres the dll file http://oceanhost.eu/jvoa0qy97tkf/LGUP_8974.dll.html
[G3 General] TwiggLe:
Will I be able to follow these steps to get my VS985 which is now rooted running Jasmine Rom back to 5.0.1 stock without root, or even flash the previous 4.4.4 ( think that's the version of KitKat it was on before.)?
[G3 General] hyelton:
Yes, that's the whole point of this guide.
[G3 General] kougloff:
Hi hyelton,

I had LG24 isai FL, Japanese Version of g3

It worked wonderfully and it decided to stop working one day after I powered it down and charge it to full

When I powered it on, it goes to bootloop and stuck at AU logo, equivalenf to lg logo I guess.

I've tried hard reset but no luck cos it is still in boot loop and stuck at AU logo after the reset. I tried to flash original firmware but it doesn't work with pop up of failed previous load

Do you have any idea what else I could try to breath a new life to the phone?
[G3 General] hyelton:
Was the phone rooted? If so maybe it did an OTA? That's usually how something like that would happen

That error you described did you use a download manager to download the firmware file? Usually that error means the file is not complete.
[G3 General] kougloff:
Nope, it is not rooted

I didn't use any download manager, download it using browser, Ok I'll try to download the firmware once again to see whether the download is clean or not

:D
[G3 General] gameplayerdo2:
yeah. i guess. but hey, alls WELL THAT ENDS WELL..

[Guide] LG G3 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

Who are you responding to? Im confused
[G3 General] kougloff:
hi hyelton.

I redownload thebfile and flashed with no problem

But after i finished inputting the first setup and right after the i get into the main screen it freeze up and restart and it goes to boot loop

I reflashed the original firmware but the problem persist

i even tried hard reset too, but it doesnt solve the problem

Have u encounter this event before?

any idea what should i do?
[G3 General] hyelton:
That happens mostly when coming from flashing an incorrect model on it or you flashed a wrong model firmware to it. Did you perform a factory reset ? By holding down the correct volume key and power and selecting reset?
[G3 General] haki.gr:
Guys, please remind us what happens when we flash an LG with a stock firmware from a different region in relation to the one that it originally came with:

1. Does an update with the PC Suite revert the firware to the original region's firmware?

2. What happens if we only update OTA from now on?
[G3 General] hyelton:
1. PC suite will either go by what's flashed or by IMEI. Which if imei then that means whatever came on your phone.

2. OTA will update whatever firmware you have flashed / county. It's not based on your phone itself.
[G3 General] haki.gr:
Would you please clarify No 1 a little further? :confused:
[G3 General] hyelton:
PC suite may read your IMEI and only flash whatever firmware came with your phone. Just like you can go to Lgkdz.com and enter your IMEI and it will pull the exact firmware meant for your phone
[G3 General] haki.gr:
So if you unbrand, the PC Suite will "rebrand" it! That's not good! :(

Thanks so much!
[G3 General] hyelton:
It wouldn't flash it unless you told it too. But PC suite will read your IMEI and want to flash what's meant for it if you do the repair /restore.

Your welcome :)
[G3 General] haki.gr:
Yeah, that's what I meant, that you can no longer repair/restore via PC Suite but you'll have to do it manually.

Thanks again for your reply!
[G3 General] kougloff:
Yep. I flashed two different version of the firmware and still it goes to boot loop after initial set up

and after that i tried hard reset. vol down plus power and yes twice to reset all the data. Even after i tried hard reset after the initial set up the phone goes to boot loop

Any suggestion?:confused:
[G3 General] EP144:
What's the difference between the KDZ and TOT method besides the GUI?

Are the KDZ files generated by LG/carriers?
[G3 General] hyelton:
It just fully depends on what's available for your phone. Example: if you have a AT&T D850 you can only use the tot method as AT&T never releases/leaks KDZ files.

Yes KDZ files are directly from LG.
[G3 General] EP144:
Does upgrading/downgrading or coming from a different ROM work with the KDV method to perform a clean installation?
[G3 General] hyelton:
Yes. As these are stock firmwares. There supposed to wipe everything.
[G3 General] gutowscr471:
Device Suspected of Rooting

I have an LG G3 (D850) with Lollipop which I rooted then unrooted a few days ago with SU. Today i received a notice that ATT had an update and I received the message about suspected of rooting while trying to update. I have read through these threads and would like to confirm that I need to download all files in the Lollipop folder and use the TOT method. Do I need I need any files outside of the Lollipop directory to get back to stock 5.0.1?
[G3 General] hyelton:
Usually unrooting is not enough. Or if you have custom recovery it won't update either. Unrooting won't remove that.

Yes everything is there and everything is in the OP. You'll flash what's there and then OTA to lollipop
[G3 General] gutowscr471:
hyelton, thanks for the quick reply. Still not clear, do I ignore the Lollipop directory for downloads and just let it update OTA?
[G3 General] hyelton:
You have the D850 right? There's no lollipop tot file for the D850. It's only obtainable through OTA or custom rom.
[G3 General] gutowscr471:
Yes, D850. Appreciate the assistance and thanks again.
[G3 General] Brickman221:
Hey, when I try to TOT method, I go to change my port to 41 and it's not there. I'm in download mode and I have the drivers installed. I am also using a USB 2.0 port directly on the motherboard. Any reason why I can't?
[G3 General] netmaniack:
If LG PC Suite is working on your D850 (Im new in LG G3 so i dont know if custom carrier phones are working whit PC Suite) then just do a "Repair upgrade errors" (that sentence might be incorrect, but the piint is the same as I have Latvian version) under Tools. It will reflash complete firmware whit all its partitions and update will be accepted. No factory reset will be applied and all personal data will be untouched.
[G3 General] hyelton:
I had awnsered there question above already. The D850 is not supported in LG suite.
[G3 General] marsxtc:
Update

Hi, AT&T had an update yesterday and after updating my phone it's now stuck in a bootloop. I'm trying to use this to go back to stock but everytime I try to run it it says" Model information Check FAIL!". Never rooted, never messed with build.prop.
[G3 General] hyelton:
Pull the battery completely and restart your PC and do the method. I get that from time to time. You just have to keep trying.

If you never rooted, changed build.prop , or messed with recovery there's no reason why you would had gotten into bootloop. Did you try performing a factory reset?

If you got bootloop after updating your phone would of had to been modified in some way.
[G3 General] marsxtc:
I did what you suggested. I swear my phone has never been modified. On the LGG3 sub reddit, one or two other people are having the same problem where after the update this happened.
[G3 General] Syndek:
Very helpful guide, but for someone on an international G3 D855 running Lollipop hoping to get back to stock 4.4 KitKat, which TOT/DLL should I download? Just wanna make sure I get it right.
[G3 General] hyelton:
Did performing a reset fix it?

Anytime when doing an update depending what it is can always cause issues when you don't reset afterwards.
[G3 General] hyelton:
If you have a D855 use the kdz method. There's more available firmwares. Download what your phone is meant for. International is a huge amount of area .. Lol. International can be anywhere to anyone. Flash the country that your near or where the phone is from.
[G3 General] Syndek:
V20h-TWN-XX

Anything? I don't do things like this too well.
[G3 General] ultrasuper:
works on un-rooted phone too?

On a STOCK LP D850, only rooted (no custom recovery), If I unroot via SuperSU.....

Can I still use this method to flash back to stock 10d? Or does this method itself, require root access at some point to work?
[G3 General] hyelton:
You don't have to unroot...

Yes you don't need root to use this as it's going back to stock. Just read the OP :)

[MENTION=2607037]hyelton[/MENTION]

Hello again mate.

I have some doubts if you would be so kind. I have a G3 D855 16GB bought in Austria, Europe.

I went to this site http://lg-phone-firmware.com/index.php?firmware=1 and inserted my IMEI and this is what it came up with a KDZ file.

Version: V20H

Country: 6NE/NORTHERN EUROPE_16G

Model: LGD855

Is this site safe? No wrong files? And will these files be for carrier free?

If you need I can PM you my IMEI

.

Also I had on my computer these following TOT+DLL files which I thought were ok to use on my phone which is carrier free and the tittle on the download was /LG G3/Stock Files/European D855/16GB Variant/

BIN_LGD855AT-00-V10e-EUR-XX-JUL-08-2014-16G-0 (TOT)

LGD855_20140526_LGFLASHv160 (DLL)

*My doubts are which files should I use? The one where I have used my IMEI (which gives a Nothern Europe version) OR the ones TOT+DLL which I already have but which say V10e-EUR-XX?

I do not care if I have to download more files (like the KDZ which I do not have yet) but I just do not want to brick my phone with the wrong file and to be honest this thing about the correct files has always confused me since sometimes I see so many files for the D855!

Thank you so much in advance and I will follow your suggestion to the letter.
[G3 General] hyelton:
That site provides the exact kdz meant for your IMEI. Just like the one I have in the OP. If you notice the download link comes directly from LGs servers. So yeah it's good :)
[G3 General] droidbits:
Thank you so much for such a fast reply.

So what you are saying is use the IMEI method and forget about the TOT that I already have and which may not be the correct file anyway??

Thanks mate. Really appreciate it. (it is more scary to flash back to stock than to flash a custom ROM!) ;)
[G3 General] hyelton:
Yes it is! Haha. But yes when using your IMEI it gives you the exact kdz.
[G3 General] droidbits:
Thanks so much. I am aware of your work for a very long time. When I see people on the threads needing some help going back to stock I always refer you to them.

You are most kind.

*what's the story with the iPhone? This is an android Forum. Are you running android on it?

;)
[G3 General] hyelton:
Thank you :)

:D yeah I got an iPhone 6 last month, my 2nd ever iPhone. I got the 5S when it came out but only owned it for a month. Your the first to say something, shockingly the TapaTalk app works a whole lot better on this iPhone than it did on my G3. But for now it's iPhone. But I do carry my old G Pro around now for my Android needs. I'm sure I'll come back to Android once something interesting comes out again or when I get the extra money. I got a heck of a deal on an new iPhone 6. AT&T paid an entire month Bill for me to get one.
[G3 General] droidbits:
Hmm...server from the download site I mentioned before is amazingly slow. It claims 26 minutes to download 1GB. Is it faster through your server?
[G3 General] hyelton:
If I have it then yeah. It's on a 2gb port :). If your still having slow speeds try out a download manager they're wonderful.
[G3 General] droidbits:
Great. Thanks for your help. I have no more questions. :D
[G3 General] hyelton:
Your welcome. Provide and update on how it goes.
[G3 General] droidbits:
Oppss! I guess I lied when I said I had not another question:

I am obviously on a custom ROM (Blisspop), with TWRP recovery and rooted of course.

Before I flash

back to stock with KDZ method and CSE (total wipe out), do I need to flash with Flashify my old stock 4.4.2 recovery or unroot?

Sorry buddy! ;)
[G3 General] hyelton:
No you do not have to unroot or change recovery. Was bliss pop based on your exact model? Or based on a different model?
[G3 General] droidbits:
I am not sure I understand the question...my bad.

When I bought the phone I was on 4.4.2 KK, then rooted with Stump, flash TWRP and then started to flash CM 12 nightlies and now BlissPop which is Lollipop 5.1.1 at this stage and based on CM 12.1 (all the latest commits).

Still rooted and recovery is TWRP 2.8.6.1

Was I clear mate? ;)
[G3 General] hyelton:
[Guide] LG G3 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

Yeah. But like some Roms might be based on a different model number. Like my D850 I ran a rom based on D855.

If you got to your settings and look if it matches your actual model you shouldn't have any issue
[G3 General] droidbits:
Oh right! Now I understand...no my BlissPop version is buit for my variant...D855 ONLY. (although they support all other variants)

So I can flash the KDZ and it will replace recovery to stock as well as unroot right? :D

Edit: Sorry just saw your added answer...I am good to go then...A MILLION THANKS!!! :D
[G3 General] droidbits:
Thank you for your dedication...will be in touch. :D

Unrooted D852 Rogers, no LTE

Guys,

I messed up CM12 flash, decided to unroot and flashed back to stock Tot file but my modem doesn't connect to anything but EDGE, any thoughts, I am using all the right files?
[G3 General] guta12:
essential post to g3
[G3 General] hyelton:
Make sure you have the correct apns and 2G is not checked under network settings?
[G3 General] fiaz.jahania:
Stuck LG G3D855

First i try to unbrick my phone and it gives error at the end by typing on the screen as "Data reset 2". after that i had restarted it again and again. Doing hard reset but all in vain.

After all this i decided to go for flashing it again through flash tool but at this point it gives error every time.

Please help me, i am very much sad :(
[G3 General] hyelton:
That's not an error... It's supposed to have a blue screen and say data reset. That's in the OP... That's when you pull the battery and put it back in and the phone will boot up normally.

Everytime you flash a G3 you'll get that same screen and you have to pull the battery and it will boot up normally.

Also that error in flashtool is a genera error. You either reboot your PC and phone a few times to fix that.
[G3 General] fiaz.jahania:
I have tried many times by pulling battery and restarting it again. but on the main screen it gives "Factory Reset Status 2" everytime. Not going in the system just hanging over there.

Because in the flashtool it had not given the status as "Passed". and after this many tries are made but same problem by saying cannot go in download mode. :rolleyes:
[G3 General] hyelton:
[emoji17] you really need to reread the OP... On flashtool anything AFTER 85% is done flashing. The rest is just rebooting. And 99% of the time it's going to say it "failed".

So what happens when you see the reset status and pull the battery and put it back in?
[G3 General] fiaz.jahania:
It goes in boot and comes again in the blue screen saying Factory Reset Status 2. :rolleyes:
[G3 General] seanwasu:
I did all those things right, the apn is good, the re root went great, everything else works very well.

I probably need to go by process of elimination, i was wondering if there are:

1. Any utilities that can help me check the D852 LTE modem/hardware issues, and

2. Any modem drivers etc. that i can re flash to reset/bolster the hardware components?

All thought are highly appreciated, this is a bummer for otherwise an excellent phone and education on android :(

Thx, Sean
[G3 General] hyelton:
There is any any "drivers". It's either going to work or not work. So did you have LTE before? What do you see that the top for the data icon?
[G3 General] DawieZA:
Seeing something similar for a D855 that was upgraded to Lollipop today. Will only connect via 2G in a 3G covered area. However in a 4G covered area it will connect fine via 4G. Looks as if the 3G portion of the modem just stopped working. Very weird indeed and still trying to get it sorted.

PS: Used the KDZ method to perform the upgrade as my work internet did not allow LG PC Suite or LGMobile Support Tool to connect to LG website.
[G3 General] hyelton:
Are you sure the data icons didn't change? Some firmwares will show 4G for 3G and LTE for LTE
[G3 General] DawieZA:
The firmware used by my service provider makes use of the E, 3G, H and 4G icons. The 4G icon represents LTE. My personal D855 with Lollipop installed cycles through the icons just fine as I change coverage areas but this one I upgraded today just does not want to work. First time I have seen this.
[G3 General] seanwasu:
I am stuck at "E" for EDGE, it used to say 4G before.

Where can i find the LG PC suite, maybe a repair attempt will switch on whatever it is that I am missing?
[G3 General] hyelton:
Well did you try a factory reset??
[G3 General] seanwasu:
I did, soft and hard resets, reflashing Tot images, pretty much everything, this is the one piece that is not working?

Found something else, maybe you can evaluate this for me:

forum.cyanogenmod.org, 106387, Lg-D852-network-issues

A post says:

NOTE: Backup EFS in TWRP prior to doing this

Solution: Old Kitkat Modem does work but renders network instability to fix flash your Lollipop modem (XDA Search). I have attached 20C-Modem for the D852 below. Flash with TWRP as anything.Also note that switching between LP roms and KK roms is not possible unless you reflash the kitkat modem respectively.

Is there a (10)Modem for KitKat I can reflash on stock, that is probably my issue as i did not backup anything before trying CM12, I was a noob then (probably still am) much older and wiser now :)
[G3 General] hyelton:
Why don't you just flash a kitkat firmware? When you flash a tot or kdz it re flashes everything including the modem.
[G3 General] seanwasu:
Ok, that is where I am at, I flashed the kitkat firmware as per teh OP guide succesfully, a few times now, but my modem seems to have been missed :(
[G3 General] hyelton:
It doesn't miss the modem. It flashes it.

Go into the phones service menu and make sure LTE/wdcdma/gsm is selected
[G3 General] seanwasu:
I was playing with the options and it clicked, then I saw your email, I actually chose LTE/WCDMA which got me off the EDGE and then the 4G kicked in !!

Thanks a lot for your patience, you guys are troopers !!:good:
[G3 General] Phalanx7621:
Hey folks, this will be my first post here in the LG G3 forums but for sure not the last. Long time android user, from way back in the My Touch 3G days, had a few since then and recently got an iPhone 5 as well as my backup. Now I'm here with the beautiful LG G3, for the next year or so rounds about. Anywho, I just followed this guide *I rooted and flashed a few ROMS just to mess around and wanted to know if I could successfully go back to stock**and this guide is amazingly well done. Everything was tip top and I wasn't worried at all. Thank you so much for writing it, and for taking the time to help us n00bs out who are just learning the ins and outs of LG phones. Kudos, thumbs up, and of course, Thanks. =-)

-Phalanx
[G3 General] hyelton:
Your very welcome :) glad it worked for you :) the G3 is nice. I just sold mine last month but might plan on getting the G4 when prices go down.
[G3 General] droidbits:
Don't be sad buddy.

Just continue on this thread and continue to follow [MENTION=2607037]hyelton[/MENTION] instructions and you will solve your problem.

*man I really feel for people so much when they brick their beloved phones. I know how I would feel...exactly the same.
[G3 General] yeziam:
Lollipop was driving me insane and factory resets weren't fixing the crashes or the 3 hour battery life. For the record, I never had any of these issues prior to upgrading to lollipop. Shame on Verizon for releasing an "upgrade" with so many issues. I was desperate to get my phone to stock and I figured the worst that could happen was I brick the phone and need to buy a new one. Well, I killed my Verizon G3 with this process. Not blaming anyone but myself as I know others have successfully done this and many here put in a lot of hard work on this issue. I didn't read through all 186 pages of this thread, just followed the first page '2015' instructions so I very likely did something wrong. However, I figured I would post in the event it may help someone who really wants to keep their G3, which I did not prior to trying this.

I followed the directions exactly as provided. The process said complete on the phone and the phone screen went black and I assumed it was rebooting. It never turned back on. The LG FlashTool said 94% and was green. After waiting 15 minutes, nothing changed, so I pulled the battery at which time FlashTool indicated a failure. Phone is dead. No series of buttons, hard resets, battery pulls or connections will show even a blip of life.
[G3 General] hyelton:
You should go back and reread the OP :p this method didn't kill your phone lol. You see how big this thread is? It's never killed anyone's phone unless they had previous problems or if they flashed an incorrect firmware.

If you read the OP you'll notice that once the phone hits 85% the phone is DONE flashing, the rest is just rebooting.... It will almost always "FAIL". Due to that. Also if it was a failed flash the phone wouldn't reboot it would stay in download mode.

Ever think it could be your battery be dead? (That has happened!). Try another battery or find a way to charge yours up to see if that may work.

Did you flash the Exact right kdz for your Verizon model? (By not flashing a different model/international variant). If you did which file was it?

What do you mean by hard resets? You can only hard reset if your phone is on.

One last thing have you tried leaving the battery out for a min then trying to turn the phone on?

I have personally flashed close to 100 LG phones from all sorts of carriers and models, including a couple of Verizon G2 and G3s. And that's not including the most likely 10,000+ here on XDA. And I've never had that issue, except in cases where the phone was already like that from other things done to and so on.
[G3 General] Phalanx7621:
For me, I had to unplug / plug back in my phone about 3 times total. It will be done completely when it reboots and has a screen with a large number 3 on it. Then it's safe to disconnect the USB, pull the battery, and put the battery back in. Then boot the phone up and enjoy. That's what worked for me. Also make SURE to use a USB 2.0 port not a USB 3.0 port that messed mine up and wouldn't let me flash correctly. (hint: a USB 3.0 port is usually located on the top of a pre-built HP or DELL , the 2.0 ports are usually on the back and on the middle of the front)
[G3 General] fiaz.jahania:
Oh Thank God, i have my fone back by following KDZ method.

Thanks for [MENTION=5171262]droidbits[/MENTION] and [MENTION=2607037]hyelton[/MENTION]. Cheers up, now i am on stock 4.4.2 D855 :o
[G3 General] pikachukaki:
I thing i have found a bug on 20p...i close my data and wifi cause i had low battery and i was away from home and when i check my phone again at battery stats wifi was running for 2hours....
[G3 General] hyelton:
Well that would be up to LG and the carrier. Any bugs would be at that level as these are stock firmwares.

So was your wifi running for 2 hours before turning it off? Even if you disabled say wifi if it was on before it will still show up there from when it was on.
