Hey Waco, thanks a ton for this walkthrough. My G2, for whatever reason, was spilling battery life like it had a hole in it, dropping as much as 10% per hour just using Chrome even after two full-battery calibrations, and I had the WiFi issues where it would never hold a connection reliably to ANY access point, not just my home router. I'm still *barely* inside the 14 day grace period, but I was panicked since I'd rooted and installed TWRP. This has my phone back to bone-stock conditions (even seems to have nuked TWRP), and I'll be going in to exchange it (hopefully for a non-lemon) tomorrow. Even the internal options list the phone as unrooted, which is all I'm sure they'll check. I couldn't be happier.

All I had to do was delete SuperSU, StickMount, and Goo - now I just have to find the receipt, which I didn't put in my usual 'saving' places. Even then, I bought the thing from a VZW brick and mortar store 11 days ago with a credit card - either they'll have a record of the transaction or I'll show them one.

EDIT: Orrrrrr, I can follow my instincts, go onto the VZW website, access my account information, find the 'equipment purchase' transaction on the 11th, and print out a new copy of the original receipt. Woo.

Much good karma and vibes headed your way, man.

In the original post, exactly how do I do this? - " extract and overwrite the one at C:\LG\LGFlashTool (which will be there if you already installed LG Flash tool like you should have. ".I've extracted but how do I overwrite the flash tool in the C drive.
[Verizon LG G2] simon_lefisch:
Cut and paste it
[Verizon LG G2] rnh:
I'm feeling really stupid. Cut and paste the extractedd DLL file exactly where in the LG flash tool? I'm sorry,could you be more specific?
[Verizon LG G2] shuttered13:
After you install the LG Flash Tool, a folder will be created in your C:\ drive as noted in the instruction, paste the file in that folder. The folder location is in blue text in the instructions.
[Verizon LG G2] rnh:
Thanks. I'm a triple idiot. I never took the dll file out of it's folder! No wonder It didn't work.
[Verizon LG G2] destruya1:
Just got my replacement phone last night. Specifically asked for an 11A, since I'm guessing it's got the OTA built-in and, for lack of a better reason, I'm guessing a 10B was built before an 11A, and I'm always a fan of more recent build dates on hardware.

Being the paranoid sort when it comes to a 450 dollar phone (bought it on sale), I did find and download the 11A stock image for posterity and safe-keeping.
[Verizon LG G2] rnh:
Well I have theunroot software and files installed correctly and the lg drivers on both phone and computer, but the flash tool is completely unresponsive to the phone in download mode. Absolutely nothing happens to the unroot software when I plug in the phone in download mode. Any thoughts?

---------- Post added at 04:14 PM ---------- Previous post was at 03:20 PM ----------

Just found the solution which is to factory reset the phone first. perhaps this should be in the OP.
[Verizon LG G2] centro714:
I'm trying to flash a Sprint LS980 device and have the LS980 tot and dll files.

However, when I'm flashing w/ the flash tool, I get a "Download FAIL!!" and in port 1 box it says "Device Model is Different!"

Anyone have any ideas on this? thanks
[Verizon LG G2] n3os33k3r:
worked flawlessly

thank you very much
[Verizon LG G2] Barshalen:
I'm getting the same error (Also on a Sprint LS980).

EDIT: It seems that restoring a stock rom backup fixed the issue. But what happens if you can't do that?
[Verizon LG G2] centro714:
OR if you don't have a stock ROM back up like me! i'm going to try and do a factory reset and see what happens.
[Verizon LG G2] centro714:
Tried a factory reset and still same error.

Can anyone help?
[Verizon LG G2] ruvort:
I have a bad situation that I need your guys help on. I installed the latest rooted OTA on my girlfriends phone but it still came up with the OTA msg and she accepted it. Needless to say it it now in a recovery loop. It is unfortunately CWM and has no terminal in it to run commands. It also doesn't seem to have OTG storage support or adb support on it either while in recovery. What can I do to get this phone working again?

Edit: Got it working
[Verizon LG G2] MicroMod777:
Here's the com41 fix. Took me over an hour to figure this out on Win7 64bit.
[Verizon LG G2] dave2775:
Worked like a charm. Took a while. Status now shows unrooted.
[Verizon LG G2] sefirosu0522:
Guys no matter what I do, I keep getting stuck after the Milky Way message. My phone just sits at the Firmware Update screen. I've tried this about 6 times. Could someone help me out?
[Verizon LG G2] centro714:
So I have this dll file: LGLS980_20130904_LGFLASHv151.dll

I'm thinking this has to be the problem since the error also says to check dll file. Does anyone have the correct dll file for LS980 sprint phone??

Screenshot of the error attached:
[Verizon LG G2] lowpro3210:
I am getting EXACTLY that, tried multiple times and telling me device is different? I triple checked and made sure I downloaded correct software for my phone..PLEASE HELP...desperately need to revert back to STOCK
[Verizon LG G2] blackwell387:
At least your getting that far. I keep getting a phone not recognize or that login i tried to uninstall flashtool s new lg drivers and software and still nothing can some one please help..

---------- Post added at 10:30 AM ---------- Previous post was at 10:25 AM ----------

Also its asking me to login, and password. phone not recognized i see that others have been having issue..can use some help. Im on sprint Ls980 sprint and windows 8.
[Verizon LG G2] simon_lefisch:
Question.....why are people with variants other than the vs980 following this guide? The thread says Verizon only. It's using this method for all other variants? I know there's another thread for restoring phones which I believe is for all variants. I'm not tying to sound like a jerk, and I apologize if I do. I'm just wondering why peeps with other variants are posting in the Verizon thread.
[Verizon LG G2] trailz:
thanks

big thanks to the O_P

worked perfectly
[Verizon LG G2] Zestyfoo:
Big thanks to the OP, you helped me to bring my G2 back to life.
[Verizon LG G2] blackwell387:
First. Of all Verizon uses the same .dot files like the sprint .dot files and dll you cant use T-Mobile ot At&t flashtool Sprint and Verizon has the same format. Something like that..if you want your on thread anf want to makr it exclusive i will be first to break that thread if it could help my cause....
[Verizon LG G2] giant6025:
Sorry for being off topic.

Guys, I just joined this forum, but I can't freakin post. Where do I klick to start posting forum threads? I can't find it. Thank you, and sorry for the inconvenience.
[Verizon LG G2] benb1974:
That's funny **** there
[Verizon LG G2] simon_lefisch:
Ahh didn't know Sprint and Verizon were the same format. Good to know. Again I was just curious....
[Verizon LG G2] giant6025:
tam tam tam....

If that **** was a link, the link doesn't work.:cowboy:
[Verizon LG G2] leemsami:
Did you figure it out, because i have the same exact problem. i used the same method before when i was stuck in a boot loop. I tried to flash an ASOP rom and now im stuck in a bootloop. i keep getting download failed and device is different. i am on verizon. i restored before and i didnt have a problem
[Verizon LG G2] simon_lefisch:
What version software were you on for stock? 10B or 11A? If you were on 11A and are trying to flash 10B firmware that may be your prob. If that's not the prob, is there anyway of finding out the what model number it says you have vs what you actually have?
[Verizon LG G2] leemsami:
I got it working. I did a hard reset. Then I went into download mode and it started working.
[Verizon LG G2] TheTanker23:
I've tried this several times and can't seem to get it to work. When I put my phone into download mode it works then immediately goes to a firmware update screen that just stays at 0%. I went through the steps and everything worked fine (the lg flash tool) but the phone is still on the firmware update screen at 0%. The instructions say to unplug the phone but the phone explicitly says "Do not unplug the USB connection until the process is complete" I need some help guys.

Edit: Nevermind I got it working. I installed the device driver again and it finished installing on the device. G2 appears to be unrooted.
[Verizon LG G2] tinpaul:
The trick i use to make this work, on the computer just change the date to jun 2010 and Google the serial number to register the program. Lg flash tool, also before you add the serial number, disconnect from the internet and it should work.
[Verizon LG G2] blackwell387:
Ok i got the part as to change the date but what exactly am i going to Google ??the registration key it ask for. Thank you for your help and time bro..
[Verizon LG G2] blackwell387:
Ok got it had to disconnect from the net and got registration key..and no root status... :))))
[Verizon LG G2] eth3rton:
Thank you OP!

Flashed a ROM and lost signal. Looked around XDA and it stated I needed to flash stock. Worked like a charm!
[Verizon LG G2] richielasalsa:
Wrong DLL!

Everytime I keep trying to do this stock method the flash tool keep saying wrong device DLL or check device i am a VS980 i have done this before but for some reason it keeps telling me that the DLL is incorrect
[Verizon LG G2] simon_lefisch:
Did you download the DLL file and replace it?

Wrong DLL File

Hi!

I'm trying to revert back to stock from cyanogenmod 11 and I cant! With the Lg Flash Tool, I've went through all the steps and get the "wrong dll file" error when I start it up. It immediately directs me to the "Model Config" screen. ALL steps have been tried over and over again with no success.

Also, I've reverted back to stop just 5 days ago but from a LG based rom not cyanogenmod based.

Any idea what im doing wrong?

Thanks,

Tim
[Verizon LG G2] killedthecat:
i have a VS98011A. keep getting CHECK DEVICE OR DLL. i have the VS98011A ToT. but the flash DLL just says VS980. is there a specific

flash DLL for the VS98011A? please help!!
[Verizon LG G2] lexknight:
They said use this for the Sprint Version, but with the Sprint Firmware...but PROBLEM

Downloaded it all, installed the LGFlashTool, put into download mode, changed to port 41, and when I try to run the LGFlashTool program after saying yes to "??? Korean camp", I get "LG USB/Paralle Lock Key is not detected"... when I hit the "OK" I then get a Login screen with Country Republic of Korea, ID, PASSWORD ...

Any Ideas...
[Verizon LG G2] CrfEpic4g:
I cant get the app extension to overwrite . Can someone explain how this is done

Edit... nevermind lol
[Verizon LG G2] almahix:
I remember that. Make sure you have read all the instructions closely and download everything mentioned. You may have to manually set the port to 41, and there is a dll that may have to be moved into the flash tool folder. Those were my 2 stumbling blocks. I don't remember which DLL, just follow the instructions word for word. It does work.
[Verizon LG G2] Cleanser2012:
I've followed all instructions but when I plug in my g2 the process doesnt begin right after putting the phone in download mode and I've rebooted a few times. I'm on the sprint variant and have all the files where they should be. Any help?

Ok found a solution instead of comm mode being set to usb be the default for me seems to be lan for some odd reason, as soon as I changed it all was well
[Verizon LG G2] abowers:
Thanks for this thread folks!!
[Verizon LG G2] clt829:
Here's some troubleshooting I went through in the process. Hope it's helpful.

I had trouble getting in download mode. For me it worked to connect the USB cable first, then hold power + Vol Up together until download mode.

I couldn't find any sign of my COM Port. I had the wrong drivers installed, so I unistalled what I had, then installed using the .exe mentioned in the OP, then connected my phone.

When I reconnected in download mode, flashing didn't start. I need change the COM Port I found above to 41. Mine came up as 7 by default.

After that it was all smooth. Phone says unrooted for sure, and ALL data is wiped. If it's not backed up off the phone, it's gone!

Thank you, WACOMalt! 100 times Thank You!

/Now I'm off to screw with my phone again :cool:
[Verizon LG G2] bobberserker:
I'm having the same problem as him but i do not understand your directions, what exactly do i do?

also in the LG flashhtool, i accidentally hit the 3rd option instead of the korea one lol, and uninstalling it doesn't give me this prompt again.

[Verizon LG G2] bobberserker:
It worked! Little bumpy at first but finally figured it out! Thank God I didn't break my brother's brand new phone! You saved me OP! :good:
[Verizon LG G2] bilestoad:
did this today, worked perfectly using vs9801a, macbook pro, parallels, windows xp.

the only things that surprised me were twofold:

1) the new file is vs9801B not A, so even though I bought my phone a few days ago, this is newer than my original? or different anyway.

and

2) this wipes out everything on the phone to make it like new. that means, no titanium backups are there, no zip files or mod files are on the phone - be sure to move any backups still on your phone to your computer before doing this.

Thanks!
[Verizon LG G2] drkow19:
I am having some troubles :( I got my VZW G2 right when it launched, and I was recently running a VS98011A rom with no issues. So I messed around and broke something today, and I tried this method with the new vs9801B file from the OP, and when it booted, setup wizard just froze at activating phone. This might not work for all G2s.

edit: or maybe it's just my phone. I used a different restore method using the VS98011A kdz, which I know I've used before, and my phone still fails and restarts itself when trying to activate. Help please! I might have borked something.
[Verizon LG G2] Rodeojones:
I was bored last night, so I decided to give this a try. Seriously, had no reason to actually go back to stock, just wanted to make sure I could do it in the event something happens and it's actually necessary someday. This worked like a charm. No issues or hiccups. I've since re-rooted but one thing I forgot to check was the rooting status in about phone. I didn't notice if this changed back to unrooted after going back to stock. Can anyone confirm this?
[Verizon LG G2] almahix:
Yes. It does NOT say rooted.
[Verizon LG G2] badkarmah187:
Sprint - Boot Loop

So, I have the Sprint Variant and my Phone is on a TeamWin Recovery boot loop since Saturday. Happened right after I stupidly tried to update to some Sprint OTA update.

So, it's my understanding that I need these (Verizon) instructions to flash back to stock (with the exception, that I use the Sprint .tot file) to fix my phone.

So far, I have not been successful. I got as far as the LG FlashTool, hitting the Yellow Arrow, ready message, unplugging phone, and download mode again.

It's failing at Download FAIL!!, Bin Model is different! Check DLL or BIN file!

I changed the com port to 41.

Here are the files, I'm using: MegaLock.dll to bypass the LG login I think.

LGLS980_20130904_LGFLASHv151.dll for the LG Flash tool

Sprint file: LS980ZV7_01.tot (3.1 GIGS)

I have attached some screenshots.

Please help!!
[Verizon LG G2] badkarmah187:
need the Sprint .tot file

Can someone share their Sprint .tot file on dropbox or something?

I might have a bad download. But I cannot access the mirrors from my work PC. Dropbox usually works here though.

i also have the sprint G2 and can not get it to work. did you have to do anything special
[Verizon LG G2] WACOMalt:
I want to remind everyone that this guide is written for VERIZON only. While it may be useful to other variants, Id appreciate keeping discussions about that in their own threads. I get a notification on every new reply. I havent turned off notifications because I want to help whoever I can, but when I come in here and see that all new posts are off topic and out of my experience, its annoying.

No worries up till now, but from now on folks, please keep discussion in here on the topic of reverting to stock for VERIZON only, or I'll have to completely abandon this thread.

That said, if someone gets me everything I need to know for the other variants, I'll try to write up a guide for those separately, or just least provide links to the proper files in this thread and expand the scope to all variants. But until that happens I want this to stay on topic of Verizon only.
[Verizon LG G2] psmith1539:
I understand and appreciate your work but since my phone is messed up I'll relentlessly pursue getting it fixed regardless of what thread I'll have to go into to get the appropriate information needed to fix it
[Verizon LG G2] WACOMalt:
Cool. So you're willing to start a new thread then :)

Have you tried KDZ methods for your phone? Also I'd try joining #lg-g2 chatroom on freenode. Tons of responsive help to be found in there.
[Verizon LG G2] nomad3018:
Quick note:

1. Your method worked perfectly! I have windows 8 and the verizon variant, and it worked like a charm! Thanks for all your hard work :good:

2. My phone has had the crazy screen issues you may have heard about, and had them before and after i rooted. So after i unrooted i decided to try the OTA update to the "A" variant before i returned it to verizon and it went fine. However, after i did that and checked the status of the phone, it went back to saying "rooted". Not a big deal i simply unrooted again, but im curious as to if anyone knows why?
[Verizon LG G2] WACOMalt:
I honestly have no idea. First time I've heard of Rooted status showing rooted even after a stock revert.
[Verizon LG G2] djohnson308:
I followed instructions to the best of my ability and the lg software just says "waiting for connection" .... any ideas?

update: If i wait several minutes it will go to download failed... it says check phone or dll, null all kinds of things making me think it has NO idea what the phone is... I see other people with sprint phones have the issue and redownload the DLL file- i did try that with no improvment.

Any help would be great thanks!
[Verizon LG G2] TheSapient:
I get to the part where I plug my phone back in. It goes into download mode, and nothing happens. Port 1 (com 41) just says "Ready!!". But flash does not start.
[Verizon LG G2] timenewton:
Mine is saying LG USB/Parallel Lock Key is not detected, then I click ok, then it asks for password/login

I did step one my computer located the device I set to COM 41
[Verizon LG G2] TheSapient:
Make sure you replace the Megalock .dll with the downloaded one.
[Verizon LG G2] kbuck13:
From my understanding getting this error usually means that the other DLL file was not in stalled.
[Verizon LG G2] TheSapient:
Yeah, I can just not get this to go. Any ideas anyone? Why doesn't it start flashing when I go back to download mode?

Also, what are the chances Sprint will exchange the phone if it shows "Security error" when I try to book up?

Also, can you send such a phone in for repair, and how much do they charge?

Edit: Is there anyway to tell if the program is even seeing my phone? I just tried the initial steps with my phone not attached, and it ran exactly the same. Got all the way to "Ready!!"

More questions. What should the phone look like when it is in download mode? Mine says download mode for a few seconds, then goes to a screen that says "Firmware Update" with a warning about unplugging it and a 0% status bar. Is that right?

What should happen on the phone when you unplug it the first time? Mine stays on that same Firmware Update screen.
[Verizon LG G2] timenewton:
Worked great thanks brotherman, needed it unrooted returning phone overheat issue and screen lag
[Verizon LG G2] TheSapient:
Can you tell me what happened on your computer screen when you hit the yellow arrow? Mine gave the Milkyway error. I hit OK. It spent about 30 seconds and then went to the Port 1 square reading "Ready!!". Is that different from what you saw?
[Verizon LG G2] psmith1539:
i had the same problem make sure you follow the part about the port i was skipping that part because my pc also said com 41 already after i followed that step it worked like a charm

[Verizon LG G2] SquireSCA:
Is this the method that I posted a few weeks ago in the other thread, using the tools that VZW includes with our phones?
[Verizon LG G2] timenewton:
After I hit the yellow button it said ready, then I unplugged my phone and plugged it back it and it started the magic, of course after restarting phone back into download mode
[Verizon LG G2] SquireSCA:
Guys, if you have the VZW Lg G2, there is a MUCH easier way to do this...

On your stock phone, is the "VZW Software Update Assistant"... Install it, and you can roll back to stock, it resets the "rooted" flag to "unrooted", etc...

If you don't have that software, get it from someone with a stock phone. It does it all by itself, almost unattended, and restores it to the "new in the box" condition...
[Verizon LG G2] kbuck13:
Where is this located?

---------- Post added at 11:44 AM ---------- Previous post was at 11:38 AM ----------

Never mind..... I noticed it when plugging in the original USB cable to my PC.

Exactly. Copy that folder to your PC, or, just install the software. It might save your bacon later on!
[Verizon LG G2] kbuck13:
I keep getting a message about a missing USB file
[Verizon LG G2] TheSapient:
I tried this process on a different computer, and success...maybe?

My phone looks like it is working just fine, as if I had just unboxed it. But the Flash Tool got to 94% (rebooting phone) and stuck there for a while. During this time, my phone rebooted and walked me though the initial settings. Eventually the flash tool said "Download failed!!! USB Port Open Fail".

Should I try again or just accept that my phone is working now? Anyway, THANKS SO MUCH to WACOmalt and hyelton!
[Verizon LG G2] sjr1616:

[Verizon LG G2] sefirosu0522:

[Verizon LG G2] sefirosu0522:
Download mode didn't work for me. Still stuck in Firmware update. I've already got the vzw drivers and lg mobile drivers installed. Did you click on install usb driver in the program? The one on the left hand side of the window.
