Thanks, but the problem is still with fastboot. I cannot erase the recovery partition even in the first step. The command gets sent to the phone, but then nothing happens. The phone just displays "fastboot: erase:recovery" and my command prompt displays "erasing 'recovery...'". I have left my phone and computer at this point for more than 12 hours and nothing every happens. Under device manager, I can see the phone under android -> USB Modem Phone ADB port, so it seems like the computer recognizes the phone, but I don't know why I can't execute any commands. If I run "fastboot devices" the command prompt displays "? fastboot"

---------- Post added at 05:18 PM ---------- Previous post was at 04:46 PM ----------

When I try to boot the phone normally (not in fastboot) it shows the LG logo and then the Tmobile logo on a white background. Device manager does recognize it as an LGE Mobile USB Serial Port (COM3), can I send some sort of command over serial?
[G2 General] aftabalam8c2:
Ok

I got it.

You are in fake fastboot mode.

You cant write.

We need time to solve.

Kindly contact me on my fb

So that i can guide u... Step by step

[MENTION=2607037]hyelton[/MENTION] I won't lie, I am a little bit nervous about doing this. I'm not new to rooting, but I am new to LG devices.

I used Stump Root (Brute Force method) to handle the rooting of my device (D800), and then I used Autorec to install TWRP, and then I used Flashify to updated TWRP to the latest.

Your guide looks fairly straight forward, but based on what I did above, would there be any problems I might run into? I need to do this for an eBay return as my eBay seller will require the phone to be restored with the stock software. If I was on a Nexus device or an OPO, I'd just fastboot flash the factory images, so that's kind of why I'm a bit on edge about this one.

Thanks for your detailed post, and your great filehost (grabbed what I needed quite quickly).

EDIT: This guide worked flawlessly. Thank you for your efforts! Much appreciated. The only recommendations I might have are as follow:

1. When you first open the LG Flash Tool, it appears to ask you what region you are from. I picked Global (it doesn't look like it ever prompts again). But for first time users, it might be worth noting :)

2. The guide with TOT method is great, but you made it in a very dark blue color. It's great for those that use XDA's light themes, but really hard to read for those who use XDA's dark themes. If I may recommend a different color, perhaps red? There's less of a shadow on the dark mode.

Either way, thanks again for a fairly painless guide.

fastboot devices show nothing for me

How to enter fastboot mode? I can connect with adb , but adb reboot bootloader simply restarts the phone

In devices I see Android Sooner Single ADB interface

and G2 with exclamation flag under Portable devices, driver is LGE Electronics, 3.13

Also more update on the trying to install tot file (see my post http://xdaforums.com/showpost.php?p=60525476&postcount=8882) I think it may somehow related to issues with unable to communicate with modem and lost IMEI.
[G2 General] hyelton:
Sorry I didn't get to you in time, I'm glad you got it back! Returning your phone?

Yeah it shouldn't matter what you choose where your from etc in flashtool.

Not sure I think most people/newer users just use the default light theme. But I'll check it out on the other themes and see how things look. Thanks for the tip!

And your welcome :).
[G2 General] Zaiaku:
Drivers installed but for some reason the only thing I can't get going is getting the device to show up in Device manager when in download mode. When in normal mode I can get files transfered with no problem. so unable to get the flash tool to start the process.. I'm running win7
[G2 General] LazyG:
Hello,

I have played a lot trying to put a D800 tot file, now not sure I've changed but I started getting different error. my phone is D800 motherboard with D802 firmware at the moment. I'm trying to put tot using LGUP_8974.dll . Having following error now

Download FAIL (1sec)

PID: XXXX

IMEI: XXXXX

[TIME] CrossDL [D802] to [D800]. SWversion

00000064

in the log there is more info

[16:44:31] CrossDL [D802] to [D800]. SWversion[D802AT-00-V20c-BUO-XX-MAY-20-2014+0][16:44:31] ¡Ú¡Ú ERROR REASON : LAF_ERROR_INVALID_INPUT_FILE

Something to do with partitions? The issue is that to write new laf.img I need a fastboot mode, but I can not enter it

If trying D800 specific dll, it complain about model difference
[G2 General] hyelton:
Did you use the drivers from the OP? When your phone is on that's completely different drivers than what's needed for download mode.
[G2 General] aftabalam8c2:
Contact me...

If i m offline here

Msg me on my fb

I can solve this.
[G2 General] LazyG:
Thank you for offering but finally I fixed it myself, although path was not straightforward

1. With a hex editor changed tot file on address 6017, from D800 to D802, as described http://xdaforums.com/showpost.php?p=56982110&postcount=251

2. This allowed me to write tot file to the phone using LG Flash tool

3. I would expect phone working after this, but it wasn't - it went to fastboot mode

4. So using your earlier description from fastboot mode I replaced images, and get download mode again

5. Now wrote original unchanged tot file , and that was the last step

So the biggest issue for me was to get a fastboot mode. I think it is not described well on xda, at least I wasn't able to find a description for this

Is there a stock lollipop for LS980?

Sent from my LG Optimus G Pro E980
[G2 General] guitarboy021:
Does anyone know how to fix NFC? It just doesnt turn on. After I first used freegee and soft bricked my phone, since then its been this way and even though I restored back to stock, everything was fixed except NFC. I even installed cm 12.1 then blisspop v3.2 but the issue remains.

Note: Im using OEM battery so its probably not the battery.
[G2 General] whatimad:
Please help me! Touch screen no longer work well

My phone is d802 I tried to update it to lollipop with LGMobile Support Tool. It went well during the update

but whene the phone is on the Touch screen no longer work well !!!

Also the IMIE shows unknown and When i CONNECT the Phone with my pc the Internal memory shows 10 gb Although my phone is 32 gb!!!

i tried updat with kdz files and the same thing

What can I do? please I'm lost

sorry for my english
[G2 General] hyelton:
Did you perform a factory reset?

Your phone storage changed because you flashed a 16gb kdz on your phone.
[G2 General] Zaiaku:
Finally got this going and wow. For some reason the port didnt didn't save. Once I did that everything went through smoothly. Now if I can find a TOT file for Verizon G2 for KITKAT I will be all good.

Never found it. Thanks. There was too many bugs with lollipop. Got it this G2 for $60 from a guy cuz the screen kept shutting off. Thought it was a software issue so wanted to take off lollipop and put KK on it. Just reloaded it with the steps here and boom phone working 100%. Thanks
[G2 General] NBreunig3:
Anyway to disable the model check. For me the check fails. I am hard bricked and need to disable it for the flash to work.
[G2 General] hyelton:
You don't disable it. Use the dll in the Op that says when you have issues flashing use this.

Or use a hex editor.
[G2 General] hyelton:
Good deal! Glad you fixed it :)

That problem usually happens when you flash something that's not meant for it or wrong model.
[G2 General] NBreunig3:
Then i get the crossed-dl error
[G2 General] hyelton:
Oh okay. Yeah youll have to use a hexeditor.
[G2 General] NBreunig3:
What do I do with the hexeditor?
[G2 General] kuriouss:
A silly question: if I have a D802 three UK open phone with 20D software, can I install a Hungarian open D802 20B stock Rom on it? Thanks for any answers ?
[G2 General] hyelton:
Yes. But make sure your flashing the for the correct size for your phone.
[G2 General] whatimad:
help

yes i perform a factory reset

please tell me what can i do ?
[G2 General] sky|ined:
Hi. The flashing process starts only after I've disconnected and reconnected the device and it all seems OK. But after a short while the phone (LG G2 D800) disconnects and then reconnects on its own (windows familiar sound that a usb device has been connected/disconnected) thus halting the flashing process (download fail error). I tried a few times and always get the same. Phone is rooted and bricked, I get a black screen most of the time, the LG logo appears for a split second, but I know I'm into download mode successfully because the correct devices and drivers appear on windows device manager and because the flashing proccess works, up to a point.
[G2 General] hyelton:
You never stated works up until what point? You do sometimes have to unplug and replug to start flashing but what percent is it when it fails?

That image below loaded after I posted but it still doesn't show your percent. But have you tried restarting your computer? Making sure your using a good USB port maybe try another ? Try another USB cable?

Make sure your not running any programs like LG suite etc.
[G2 General] sky|ined:
I tried about 30 times and I succeeded. The process was 100% completed. The phone booted, it made the sound it does when booting up, I saw the LG sing for a split second, then nothing. I fiddled with it a little bit, I saw again the screen for a split second, something about the sim card (probably missing) and then darkness again. I don't know whether this is a software issue or whether I disconnected a diplay connector somehow. But as far as the flashing goes I think I had a success.
[G2 General] hyelton:
Good! It wouldn't really be a software issue as this file has been used 1,000s of times never seen that issue.
[G2 General] sky|ined:
Thanks. Now I have to figure out why the display is showing nothing. I fix that, I can enjoy the phone at last.
[G2 General] thetolsonator:
So many pages of info to go through, running D80120g at the moment and was looking to upgrade to Lollipop. Assuming the worst, do I have to unroot and flash the stock and update the old fashioned way or can I grab the LP KDZ and flash that instead?
[G2 General] Pr3no:
There were two kdz files for Lollipop for my country, one with the name Hungary 16 GB D80230d_00 and the other with the name Hungary OPEN 16GB D80230a_00.

Which one do I need? There was nothing in the settings that'd tell me which one do I need.
[G2 General] hyelton:
If there's lollipop for your model just flash It. That's the whole point of this guide :). Upgrading, downgrading, going back to stock.
[G2 General] hyelton:
Well first of all is your phone 16GB or 32Gb? If 16GB then flash whichever one. open means no bloatware.
[G2 General] thetolsonator:
Using the newer instructions, am I replacing the TOT with the KDZ for lollipop (which I grabbed from your server, thanks!)
[G2 General] hyelton:
Really confused as to what you just said. :p Tot and kdz are two different methods.
[G2 General] thetolsonator:
Well balls. Might have to use the old method then.
[G2 General] hyelton:
Huh? I am really confused lol. What old method? The old method is dead. If you read the OP there are two methods. One for kdz and one for tot. Everything in the OP is for what your wanting to do. There's no 1 method that does both.
[G2 General] thetolsonator:
Sorry, I meant old as in the KDZ method.
[G2 General] hyelton:
There's no reason to use that even if it works anymore. That method has not been needed in over a year now.
[G2 General] thetolsonator:
Ok so then I grab the TOT and flash that, then update the OTA way from there. I'm assuming I have to update via OTA because the TOT file for the LG G2 Tmobile is dated August2013 or August2014 (going by last modified) according to your file listing.

Am I correct?
[G2 General] hyelton:
Your best bet would be to use the kdz method as the kdz files are most likely newer.
[G2 General] alexguy96:
I tried running the LG flash tool but it said that I had a wrong model based on my DLL file. My phone is originally an LG G2 D801 t-mobile model, but for some reason (after installing a custom ROM) it shows up as an LG F350K. Should I download the TOT and DLL for that phone instead of mine? I'm confused
[G2 General] hyelton:
First of all of it changed your model that's because that rom was built or meant for a different model... If you flash that on your T-Mobile phone you'll result in bad problems... Never flash a model not meant for it. Roms are usually fine but stock firmwares can really do some damage. You'll need to use a hex editor to change the model number to fix it. Or if you still have a working phone just flash a custom rom that's for the D801 then flash back to stock.
[G2 General] alexguy96:
How would I go about changing the model through a hex editor? My phone is not functionally, it can only go into download mode.
[G2 General] midfield99:
Can I flash VS98012B phone with a VS98027A.kdz file with the kdz method? I could not find a 98012B kdz file.
[G2 General] hyelton:
Yes as it's the same model
[G2 General] aishwary.ranjan:
i don't know what to do now!

my phone is stuck

i was getting it back to the stock rom and it not happening. i'm new so maybe someone can help

i've downloaded the India 32GB D80210C_00.kdz

and followed all the steps but i don't know what's happening
[G2 General] hyelton:
Well 2 things. You never said what your phone was , and 2 that's not download mode. You need to put your phone in download mode
[G2 General] aishwary.ranjan:
and then this is happening when i start again

the installing of stock rom went to the third option

i guess that's uploading on the phone

but now it's just remaining on the first option

i'm stuck and don't even know what to do now
[G2 General] hyelton:
You never said what your phone model is, AND like I said your phone needs to be in download mode.
[G2 General] aishwary.ranjan:

[G2 General] aishwary.ranjan:
what to do

tried all the mentioned things but it is still not getting ahead of the first option. it gets stuck on 60%

please help!
[G2 General] hyelton:
Everything you need to know is in the OP for putting it into download Mode.

You keep the setting as it is. Your screenshot shows the phone in fastboot not download mode.
[G2 General] aftabalam8c2:
U can contact me..

I leave a pm for u...see this.

I have exams so rarely using xda.

Its not download mode.

U are stuck in fastboot mode
[G2 General] hyelton:
I may have asked you this before, but why don't you just post the solution instead of to PM?
[G2 General] hyelton:
Thanks! Yeah undersood. I'll link to this post in the OP. Was this what you had took down from another thread?
[G2 General] aftabalam8c2:
One more thing.

Before doing anything u must be confident about the model of ur phone.

Otherwise u can hard brick it.

Cos most of the indian guy buy refurbished lg phone.

So he care full
[G2 General] lexfrancis:
Hi. I'm having trouble finding the right kdz file. My model is D802 32gb. The software version is D80210b EUR XX.

On storagecow.eu I can find these files:

LGD802AT-V10b-EUR-XX-SEP-07-2013-16G.exe

Europe Open D80210A_00.kdz

Europe OPEN D80220B_00.kdz

Europe OPEN D80220D_00.kdz

Europe OPEN D80220H_00.kdz

Almost went with the first one but it says 16G at the end, so not sure. Will any of these work? Checked on lgkdz.com but apparently there is no kdz for my model. If none of these files will work, will one be released in the future?

Thanks
[G2 General] hyelton:
As stated in the Op if it has 16Gb in the file name its 16GB if not stated its 32GB.

The first one is a tot file. But yes the rest will work on your phone.
[G2 General] lexfrancis:
I'm getting "upgrade stopped due to an error." Not sure how far it got before the error, and there's no log, just a box saying "time elapsed: ..."

The phone does show up in device manager as LGE AndroidNet USB Serial Port

I'm using Windows 7, but t's not a genuine copy, and there are system updates available for it not yet installed. Might that have something to do with it?

Not sure what to do. Been reading the thread and I'm seeing that you suggested re-installing the drivers, rebooting the PC, using different cables/ports etc. I'm just not sure whether or not I can disconnect the usb, phone screen is saying not to until it's complete. If I were to disconnect it, or restart the PC, or try to reboot the phone, what would happen?
[G2 General] aftabalam8c2:
This was taken from my own thread.

I took a part from it..

Only solution of fastboot.

U can use it...i would not mind.

now I've installed lolipop but no network, i mean its not reading sim

can u help me unlocking my mobile plz?

can u help plz??
[G2 General] hyelton:
Well you most likely flashed something you shouldn't had and could had lost you Efs which if you didn't back up is gone.

You never stated what your using that phone on. The LS model is the USA Sprint Variant which by default without moding /changing is a CDMA phone not a gsm phone so I don't know if your in another country or using another carrier you never stated. Did you make sure it's set to GSM only under network settings if you are not in the USA?

Stuck in download mode (LGE AndroidNet USB Modem) issue

Everytime i install the lg drivers the LGE AndroidNet USB Modem always failed. So when i flashed the stock firmware using lg flash tool got stuck in 2% and all messed up. Ill be posting as well the issues so please help!
[G2 General] hyelton:
You'll need lgemodem to work to be able to flash. Did you check device manager and look under ports? Did you restart your PC?
[G2 General] darylazores:
I did restart my pc several times and install again the driver but still the same outcome. Im beggining to think that this wont work anymore. How would i fix the lge modem issue as its always failed. I also did check on the device manager and showing unknown device as what ive attached below. Is there anyway to get the lge modem installed? and how? if you could help sir that would be amazing. Ill treat you to a beer! Feeling desperate now :(
[G2 General] hyelton:
First all there's no way at the ever this method will decist to work. Unless LG Changes there way which I dought will be anytime soon.

Right now its just an issue with your computer / drivers. Once that is fixed you should be able to flash.

If you have or want to use teamviewer Pm me the info and I'll try and troubleshoot it on my end.

Also what is your model number?
[G2 General] darylazores:
OMG youre a saint! just offering me of help is a big thing for me right now! I just installed team viewer on my pc. Ill send you the remote control details. My lg g2 is d802 international version. Yah i think its an issue with the actual driver/computer not syncing together.
[G2 General] hyelton:
Its no problem, I rarely do teamviewer due to the amount of time it can take, but If its a driver issue, I`d hope it will be a simple fix depending on the PC lol.

[G2 General] hyelton:
Thank you so much!

I`m glad you got it :)

Was it your phone or her phone? :p
[G2 General] phatmanxxl:
She just got the Galaxy S6, I was using the Desire, she was using the G2 (used to be my phone) but since she got the next upgrade I went back to the G2 but it was running stock rooted JB...yuck. I flashed the CM 12 ROM and LP radio then went to update the recovery, which totally borked it. I got the fastboot USB text for some reason.

I rebooted the phone and just got an LG splash bootloop. So basically it bricked. I would have broke a nice phone and would have been stick using windows again, the Desire is going to my daughter and the G Pro has a broken SIM Port

The download mode worked and thanks to your post the restoration process was easy to follow.

After reading several threads about people who experienced similar problems its best to leave the boot loader and radios alone. I think flashing the LP radio after I flashed the CM 12 ROM then updated the recovery is what screwed up the partitions.

So I restored the phone to JB firmware, used the I/O root, flashed the latest TWRP, then flashed CM12. All is good now.
[G2 General] pikachukaki:
this is the 1st time i try to update a phone without root and custom recovery....i can't remember the site i check with IMEI it give me there is an update for my friends G2 but the OTA didnt find any...also i could try to update with LG PC Suite it will work?and if it didn't i can flash whatever country they contain bloadware or carrier specific apps???
[G2 General] hyelton:
Your post is sort of confusing.

First of all you didn't say your model. There are several different models and sizes.
[G2 General] pikachukaki:
yeah sorry...its a d802 from france D80220d_208_10
[G2 General] hyelton:
If you want to update you can flash any d802 firmware as long as you flash the correct size.
[G2 General] pikachukaki:
its 16GB if you mean this...but i wann try to update it with lg pc suite if i can and then try with the lg tools!!!it is possible??
[G2 General] hyelton:
Then try it with lg PC suite. But the method in the OP is your other option.
[G2 General] pikachukaki:
i try with lg pc suite and it found an update i will try it and then we will see!!
[G2 General] thenarratorr:
Sooo....I used this before way back on my G2. I've recently been flashing different roms after getting to 39A on my VS980.

I tried to go back to stock with XDABEBBS software but got bootloop.

Downloaded Lollipop from KDZ, ran the program all is good until it goes to step after selecting language. Says device is not connected? I can confirm it's in download mode, all drivers installed, but nothing works.

Not sure what to do...
[G2 General] hyelton:
Not sure what you mean by xdabebbs software? You mean LG flashtool like my guide? Or do you mean his Rom? There's only 2 tools that work for going back to factory stock and there in the OP.

Did you make sure lgemodem does show up under ports in device manager when phone is plugged in and in download mode? Got a screenshot of the error? Cause when using the kdz method if it gives an error about server error it's actually still flashing if you look at the progress bar.
[G2 General] thenarratorr:
My bad, should have explained further, lol.

So I got the phone, I updated it all to lollipop 39A. Decided to root and had TWRP, I flashed a couple roms but wanted to back to complete stock firmware. I uninstalled and unrooted through SuperSu, then went into recovery and flashed the stock firmware xdabebb had and when I went to boot, i got into a bootloop, tried to go to recovery and nothing there, so I was like ..oh I'm probably screwed ha

So I downloaded the LG support tool, downloaded Lollipop KDZ, did all that, and I select it all and get here and it just stops working.
[G2 General] hyelton:
Need to see under ports. Not the MTP driver. That's not needed. You need to look for the com port :p
[G2 General] thenarratorr:
Okay here we go, I'll admit, little less tech savvy at times.
