RETURN TO STOCK AT&T & Sprint Version ONLY!

Download

1. LGFlashTools v1.5 - Download

2. Drivers - Download

3. Download Both Stock Image File and DLL (Both Files) - Download

Credit to [MENTION=1436971]madmack[/MENTION] for making most of this Guide for the G Pro Which also works on our G2

3.1 - FOR SPRINT FIRMWARE - Click Here

Install

1. Install the LG drivers downloaded above.

2. Install LGFlashTools v1.6 (but don't run it)

3. Extract the TOT file from the ZIP

Drivers initialization

1. Put the phone into download mode. (Turn off device PRESS VOL UP while plugging in the micro usb cable. If this doesn't work, try holding both volume keys instead)

2. Let the phone initialize and install the drivers. Once done, in Device manager, you should see the LG phone listed under COM ports (something along these lines).

3. Find that LG entry in Device Manager, click on Properties, Advanced and then change the COM port to COM41 and close/save.

4. Unplug your phone! Important step.

LGFlashTools

To get this tool to work, you'll need to do a few tricks.

1. Set the computer's date to some time in July 2012 or before.

2. Disconnect the internet

3. Find a serial number or register key from somewhere on the web (a google search for lgflashtools serial will yield some results). Can't help you here and please don't share any keys in this thread or get us in trouble.

4. Execute the LGFlashTools. It should ask you for a key, put it in. Now you should see a dialog where you can load the DLL file and the TOT files that you extracted earlier. Put them both in here. Click ok

Flashing

5. There is a yellow arrow on the top left. Click on it to initialize the process. Once done, it should say "ready/finished" or whatever.

6. Put the phone in download mode again, and plug it into the USB port. LG FLash Tools should start flashing it automatically. When it's done, it'll automatically reboot into your stock AT&T rom and all of your data and internal sdcard files are gone.

So everything listed in this quote is what I have to do in be able to flash back to stock for At&t? I was just wanting to make sure it wasnt for Sprint only because after the what to download section it says 3.1 for Sprint but doesnt state anything about AT&T. Sorry to be a pain! And thank you!

Ok so im on sprint.

Same deal i can get only in twrp recover (stock rooted and i clicked the update by ,mistake).

I have all the files and im downloading the sprint files.

Can i save the pictures before i do the verizon version? ( when i plug in my phone in my laptop in recovery it shows it under Other as g2)..... so there is no folder and i cant save my wifes pics. I understand the verizon method if it works ok it will delete everything.

I had a nand backup but it doesnt work (i tried the terminal thing and adb devices shows a weird number then recovery by it but when i do adb shell it just gives a few numbers and letters on the next line)

If i cant save ppics but i save the phone im still ok (maybe not the wife ...she doesnt want wifi tether anymore after a day of no phone)

I downloaded and installed european open kdz (have international 802) cos my G2 was stuck in bootloop but have now lost LTE... is there anywhere to download just the firmware to get LTE back or do I need to reinstall whole kdz? and which one? (has LTE built in?) thanks
[G2 General] adu1982:
Havent had the patience to wait for an answer so just did it. And I want to say thanks to poster/developers. I am now waiting for it to download the ota and give it back to the wife.......this was a scare when i couldnt use the nand i had i was like ooooh sh...
[G2 General] hyelton:
Whats your carrier? And are you using the correct APN? I know on att some international phones/firmwares want to use the WAP.Cingular APN which makes LTE NOT work. Also be sure to check under network settings after checking your APN to under network type to make sure its set on LTE.
[G2 General] Jostian:
hi am on Vodacom (is an LTE network), had LTE under network settings before I flashed the kzd, am using correct APN yes, and under network settings there is only GSM and WCDMA options no LTE option, thanks
[G2 General] sanke1:
Indian and Hong Kong ROMs are getting faster updates. (Because no carrier bundling and hence lesser testing required)

But the only drawback is LG has not enabled LTE on Indian ROM yet. So you will have to enable LTE manually after every reboot.

Don't know about LTE status on Hongkong 10C ROM.
[G2 General] MazdaGTI:
Worked perfect! Thanks a lot, saved for mee 500€:good:
[G2 General] sanke1:
I think I may have found a solution for people getting stuck at 49%. I tried to restore 10C KDZ file and was getting stuck at 49%.

You have to go into TWRP and erase the System, Data, Cache and Dalvik Cache.

Try the restore process again. Then it went past 49%.
[G2 General] gujabon:
Need your help!

Hi hyelton !

I'm Chai from Thailand and now I have problem with my G2.

I did ROOTED my phone since 2 months ago and I decide to Factory Reset it.

I made a reset by use backup/reset function directly from phone.

Note

I didn't ROOTED it after this reset.

Everything looks good until I restart my phone.

It shows black screen and below has a messege "security error" and ROOTED in red font.

I found your topic from Internet and did it exactly your advice but it can't be done.

I tried either KDZ Method or TOT Method.

Please see error pictures in attach files.

I really need your help ! :crying::crying::crying:

[G2 General] NIGHTMARE-:
Use lg tool 2014 version and flash the file. Check before flashing which version you used previously. However i tried different versions its work for fine for me. I was on 4.4.2.
[G2 General] hyelton:
Hi, first of all perform a reset does not remove root.. Root will still be there.

Where you running MM 6.0? If so you must use LGUP. Or make sure your using a USB 2.0 port and the cable that came with the phone.
[G2 General] berezker:
Thank you very much

Everything worked perfectly

Which File to Download

For the

"1.Download Everything!

1.1)Download Both Stock Image & DLL File – Download Here" link

which one am I supposed to download, I am so confused, like how am I even supposed to know

I have Android Version 5.0.2, Software Version D80030g, Kernel version 3.4.0, and I have a AT&T LG G2

Thnx for the help, I recently rooted my phone and tried to install twrp from a youtube video and for that I got a brick :/
[G2 General] chudur:
Some questions

1) I when i try to enter download mode, the progress bar just stays at 0%. Do i just go ahead and flash anyways?

2) Which .kdz file should i be downloading for verizon wireless 32gb model?
[G2 General] spc_hicks09:
1. Yes the bar will stay at 0% until you flash the kdz file.

2. 39a is the latest kdz I believe and is the easiest to root, and install TWRP.
[G2 General] chudur:
On the storagecow website, under Verizon > KDZ method there's only the 24A and 27A. Is this the correct 39A?

In the end does it really matter? I can go from 24A to 39A right?

in the back cover is d802 but in the system is d803

Hello every one

I have a confusion :s in my phone back covers i have lg-d802 fcc id znfd802 !! but in the phone system in Reg&security i have USA fcc id znfd803 CANADA ic id 2703c-d803 still in hardware info lg-d803 ! :s :'s

my questions is : did i have a d802 or d803 ? how can i change the system to have d802 as a model in the system ? because i tried to flash a d802 stock rom following many xda thread (http://xdaforums.com/showthread.php?t=2432476) but didn't work stuck at 2% in LGFlashTool2014 BUT when i use a d803 Firmware the flash is done but still I have the kitkat and d803

my goal is to change the system from d803 to d802 (because it's written in the back cover d802) and have the lollipop android !

thank you very much and best regards
[G2 General] NinjaChachi:
When I go into Download Mode it stays at download mode for like 3 seconds and then switches to Firmware Upgrade screen, my computer doesn't recognize this at all and I can't continue with the flash tool

EDIT: Everything worked, I switched computers and it worked!

hi, I want to downgrade my LG G2 LS980 (Sprint) from Lollipop 5 (ZVG) to Kitkat (ZVE) by using the tot method. Is it possible?

Please help me, thanks
[G2 General] ashhad101:
Yeah it should be possible but be careful one wrong step and ur device will get messed up.
[G2 General] atifmas:
Thank you for the reply, Yes I'll do the same steps as written in the 1st post.
[G2 General] ashhad101:
If you get stuck at any step then just post it here and why are u going from lollipop to kitkat just asking. Peace
[G2 General] atifmas:
I personally don't like lollipop and has a feeling my G2 has some issues after I upgraded. The biggest issue is slow battery charging and fast draining and sometimes the devive didn't charged at all after 1 or 2 hrs it plugged in. So thats why I decided to go back to KK.
[G2 General] ashhad101:
Hmm and one more thing if your device is sim unlocked and you will go to kk then your device will get sim locked and only sprint sim will work, it shouldn't be a problem if you are already using sprint otherwise you will have to unlock it or just install a rom.
[G2 General] atifmas:
My device is sim locked and I live in asian country, so do I need to root it and perform some kind of sim unlock patch?
[G2 General] atifmas:
I have successfully downgraded my LG G2 LS980 from ZVG Lollipop to ZVE Kitkat . Thanks to the tot method posted by hyelton

[Q] LG G2 bootloop, No recovery mode, No download mode..HELP!!!

Hello every one....

Yesterday i was trying some cm13 theams i downloaded and suddenly my phone crashed and now its stuck in boot animation. I do have a TWRP but i can't boot into it. I also tried every combination to boot into Download mode but unsuccessful.

Note: Recovery boot was not working after i installed cm 13 on my device and i was using some recovery boot application in order to get into TWRP.

I used KDZ method before to go back to stock but with out download mode i can't try this method. There are some methods to fix download mode but for that USB debugging must be enable in developers options. I am tired of surfing on internet to solve this issue and ruining out of options. May be some of you guys can help me out in this regard, i will highly appreciate any kind of help...

Thanks
[G2 General] ceza1380:
Try with charger plugged in. If you stuck in bootloop then it can be that your battery dead. It's a common issue with G3 battery. Try to boot with charger plugged in.
[G2 General] imrankhnn:
Thanks for the reply.. I can see LG logo and boot animation so battery is working fine. My real problem is that i cant get into recovery and download mode because USB debugging in not enabled. With phone stuck in bootloops there is no way i can enable USB debugging to use any of the OS rescue method..:crying:

But i am not giving up there must be some way to push files into the phone in order to get into download mode or recovery mode. Apologies for my English!!
[G2 General] spc_hicks09:
USB Debugging doesn't need to be on for Download Mode to work.

Turn phone off

Press and hold volume up

Plug phone into a computer USB port

Plug other end of cable into phone

You're now in download mode
[G2 General] edderspcs:
I followed this exactly and it all worked for me. Back to stock with only one problem. My T Mobile Hotspot has stopped working. I can connect on my laptop but I have no net access. I get a message " Your DNS server might be unavailable.".

My SIM works fine in my wife's G3 and also in another phone I have. It's just my G2 that I had to restore to stock.

Any help is appreciated/. Thanks.
[G2 General] imrankhnn:
Tried this like 100 times but still black screen no download mode. Though my phone boots but stuck in boot animation. Also my phone didn't show up in device manager. Uninstall and reinstalled LG drivers still no luck.
[G2 General] spc_hicks09:
You are doing something wrong then because you won't even see the boot animation if you're doing it right.
[G2 General] hyelton:
What is your model? If its sprint you have to flash a certain rom. If its a normal GSM device you must buy an unlock code.

Hello all.

I tried to search for common folder but i didn't find anything. The problem is that my device is displayed as ''unknown'', as you say.

[G2 General] hyelton:
And are you using it on Sprint? If not remember that is a CDMA device and has to be modified for the sim slot to work on non sprint sims. You have to root for the sim slot to work if not using it on sprint

Sorry for bad english.

Thanks for helping.

[G2 General] savein:
now my phone just into in firmware mode when i try turn on my phone after flashing at 47% ,how to solving this problem ?

use lg g2 d802 LGUP method
[G2 General] CPKallday:
Alright, so I did this and succeeded multiple times. Then I kept screwing up with the ROM and missing steps and eventually I got stuck on the firmware screen like the other guy that is in here. I used the unbrickable tutorial and that worked. After I did that I reflashed and now when I turn my phone on the LG symbol comes up and immediately goes away and then it proceeds with the set up and touch to speech accessibility thing. I can't get my screen to come back, but it obviously works because it flashes the LG symbol at the beginning.

I have ls980 and I used LG FlashTool. Any ideas?
[G2 General] hyelton:
Are you sure it's an LS980? Where you one of the D802 users that actually had a different model? Or do you physically have a LS980 and use it on Sprint?
[G2 General] CPKallday:
Yes, I am sure. No I wasn't.

I have a LS980 and I'm trying to switch it off of sprint....
[G2 General] NIGHTMARE-:
^^ Open the back cover and check
[G2 General] hyelton:
If they were using it on Sprint then it's definitely the correct model.
[G2 General] hyelton:
What firmware was you trying to flash? What do you mean switch it off sprint? This device will only work on sprint or a non USA carrier with modification.
[G2 General] rebelx:
My OTA updates are not working after I had previously rooted my G2, so I'd like to go back.

I have a Sprint G2 LS980ZVG. The phone is no longer active with Sprint (it is activated with RingPlus).

When downloading the KDZ files on the OP, there is no "G" variant. It only goes up to "E." I hope that is OK if I use that zip file? EDIT: Apparently, when I downloaded the E version, and extracted it, I got a TOT file instead of a KDZ file. The KDZ method seems a lot simpler to use, but I have no file to select as it's a TOT and not a KDZ!

Will the fact that the phone is no longer activated on Sprint be a problem?

EDIT: Just did the TOT method. Hopefully it works--the software looks a little different (older), but I'm trying an OTA update now. If it works, then I'm good, but if not, then I'll need to reassess.

[G2 General] hyelton:
I'm glad it worked! Remember the Sprint model is TOT method only. There's never a kdz file for sprint devices.
[G2 General] hyelton:
Looks like you flashed a wrong model firmware... You never stated what your model is. If you were sold a "d802" looks like you flashed a D802 firmware on a non D802 device. You need to take off your back cover and see what your actual model number is.
[G2 General] rebelx:
Doh! That would explain it!

So far so good. I'm now on a new software build apparently: LS980ZVI. Looks like updates are working as I haven't had any errors yet! Thanks!

Dear Friend, I hope you can reply my question.

My LG G2 D802 International version rooted and Installed Cloudy G2 3.3 rom and Installed Dorimanx kernel.

sorry I don't wanna tell you long story but I have to.

I completely dismantled the phone to replace the LCD screen and reassembled. when I boot the phone sim card not detected! I did many tricks from many website but no use! finally decided to flash the stock rom.

But there is a problem started I couldn't flash, all connection ok tried with 3 deferent computers and deferent USB cables. when start the flashing the OS upgrading only 2 % than error message server not found try to remove the battery and restart the process. even I open the phone and removed the battery and retried but keep showing the same error.:confused:

shall I try the TOT method?

Please help me,

Thanks
[G2 General] hyelton:
The server not found message is supposed to pop up... You drag that window out of the way (don't click exit) and you'll see that the whole time it's been flashing your phone and you've been stopping the process. Your supposed to ignore that message.
[G2 General] wiedyou:
Where u get .tot files from zip? im confused for that, and i have LG D686 i cant find the .tot files from your link, but i have .kdz files for same version on my LG D686.

i have try LG Flash Tool 2014 didnt work (using .kdz file), i try KDZ Updater didnt work too (using .kdz file), using LG FlashTool V1.8.1.1023 didnt work too (using .kdz file),, now what? really confusing @.@ please help thx.
[G2 General] hyelton:
You extract the zip and get a tot.. Also you don't see any D686 tot files as that is not a G2. Your posting in the LG G2 section ;p If you have a kdz just use the kdz method.
[G2 General] wiedyou:
i tried many time on every .kdz method but no one works, any idea?

nb: bootloop on my phone cant factory reset because error: boot certification verification -1, any idea?
[G2 General] hyelton:
How did the boot loop occur or the reason you were flashing back to stock in the first place? If it happened at random and you were not rooted that sounds like a hardware problem.

Was the phone running MM 6.0? If so you must use lgup.
[G2 General] wiedyou:
yea boot loop is the 1st reason im flashing back to use factory reset,, sometimes i can login on my phone but its reboot again for any several minutes, sometimes bootloop too, sometimes can use again, reboot again. i think i miss something in android data, like 3days ago i lost google play services, so i cant use google play, any google apps, but im not deleting that program, its deleting itself, i dunno why, so i installed again the google play services its back again, i can use any google app,, i think the data android its deleting itself in my phone, dunno why,,

what is it phone running MM 6.0?
[G2 General] swensonator:
I have a D800 that was on stock Lollipop. I rooted using the LG One Touch Root. Success. I attempted to install TWRP using autorec and failed. Tried again using TWRP Manager and got a message saying that "Something went wrong" and telling me to reboot. Phone started to reboot and a couple lines of text appeared on top of LG logo, then screen when black. Now screen will illuminate when I try to put it in download mode, and will then cycle between illuminated and off (I'm assuming it is in a shortened boot loop where it never reaches any of the logos).

I tried following the instructions on in the 1st post and got an error about having the wrong model. Switched to the other dll that ignores the check (LGUP_8947.dll), but get a difference error

Error: CrossDL [] to [D800]. SWversion

I'm using the LGD800AT-01-V20c-310-410....... tot file. Advice on how to fix the problem?

Thanks.
[G2 General] swensonator:
So a little more information. In addition to the error I reported, I also see the following:

PID: NULL
IMEI: NULL
Model:
DLL: D800
BIN: LGD800AT-01-V20C.........etc.
SWV:
SWOV:

So, it is obviously making some sort of successful communication with my phone, or I assume I wouldn't see any out (just stay of "Waiting for connection"). However, due to PID, IMEI, and Model being NULL/Blank, does that mean that it isn't getting any good data back from the phone? (This makes the "[] to [D800]" error make more sense.)

What do you think? Is there something else I can try for force the upload of the stock ROM?
[G2 General] hyelton:
The phone will need to be in download mode before it can flash. You are using a usb 2.0 port correct? Usb 3.0 won't work.
[G2 General] swensonator:
As I said in my first post, I can't get the phone to boot into any mode. I *think* it attempts to go into download mode, but it boot loops before getting there. I never see any logos or text on the screen, but I do see the screen illuminate -> dark -> illuminate -> dark. (No download mode, no recovery mode, nothing.)

So if I can't get it to fully boot into download mode, do I need to look elsewhere to try and fix my phone? When I connect it Linux, I can actually see a bunch of files on the phone. Can I manually upload files to the phone in Linux (I'm thinking maybe I could use something like dd)?

Any help is appreciated.
