Try with tot method.

It will tell u the error during flash
[G2 General] kuriouss:
Can anyone tell, what happens if I accidentally flash a non-open kdz to my open phone? I mean, I just simply have to flash an open kdz and then everything should work normally again?
[G2 General] hyelton:
Yes it's fine. As long as your flashing the correct model and Size. If you flash a different model number or size you'd have some problems.

i can not do this because g2 is not being recognized in download mode:

"7.Press and hold the Vol UP Key and plug in the USB cable to your phone you should now see “Firmware Update/Download Mode” and be in Download mode.

8.Open up Device Manger on your PC

8.1)Click on ports and double click LGEModem

8.2)Go to Port Settings Tab and click Advaced

8.3)Change COM Port to COM41 and click Okay.

8.4)After this you may need to rereboot your phone back into download mode."
[G2 General] hyelton:
What do you mean by not recognized by the computer. When phone is in download mode are you looking under device manager and the ports tab to confirm its not?
[G2 General] efrengs19@gmail.com:
that is exactly what i mean!!! when the phone in in download mode i look under device

that is exactly what i mean!!!! When phone is in download mode i look under device manager and the ports tab to confirm, and it ir NOT there :(...... but if i connected in normal way it is there!!!
[G2 General] hyelton:
What do you mean connect normal way? Your not explaining too much. Are you making sure your using a USB 2.0 port and not 3.0?
[G2 General] efrengs19@gmail.com:
do you speak spanish?... i will try to explain me more, sorry!!! it is a ubs 2.0!!! if i turn on my phone it gets stuck at lg logo and i connect it to my pc and it is recognized by pc.... if i turn on my phone in download mode and i connect it in that way to the pc, the pc does not recognized and it should do it!!!
[G2 General] LazyG:
well, how starting from 10d increases your chances? You anyway have to pass through 20y
[G2 General] VladAndreMano:
I see many software files here, i have an LG D802, which one do i download?
[G2 General] Soufiansky:
Simply the one for D802...
[G2 General] VladAndreMano:
I know im spamming, but i really need some help guys

I wanted to flash Blisspop for my g2 and in twrp i wiped EVERYTHING by mistake, initially it booted back into twrp but then i accidentally choosed to boot into system, now my phone is stuck in a bootloop, i managed to get into download mode but its not doing anything...i really have no idea what to do..
[G2 General] LazyG:
D802 firmware vary by region and flash size 16/32 GB.

---------- Post added at 12:02 PM ---------- Previous post was at 12:01 PM ----------

Are you able to flash stock as described in this topic?
[G2 General] VladAndreMano:
It says flashing update and there is a loading bar but it never goes beyond 0%
[G2 General] LazyG:
Read guide line by line, pay attention to every detail. Problem might be in drivers, dll, port setting, etc.

For ex I've spent 2 days trying to write a tot, when changing port number in LGE modem, while it needs to be changed in the COM port.
[G2 General] VladAndreMano:
Well, i would but the thing is i cant even get to the actual guide, cause the basic drivers wont install, it stays at 0%
[G2 General] hyelton:
Your posts are really confusing. If your having trouble running the drivers installer there's something wrong with your PC or it needs to be restarted.
[G2 General] VladAndreMano:
Im sorry, i manage to get into download mode on my phone, when i do, it says that its flashing update and there is a loading bar that stays at 0%, i do have the drivers installed on my computer but it doesnt recognize my phone...
[G2 General] hyelton:
How do you know it's not recognizing your phone? Did you check under device manager and under ports an see lgemodem? That's the only way to know. Are you not starting up flashtool?
[G2 General] Soufiansky:
Install them again and reboot your computer. Try different ports too.
[G2 General] LazyG:
Then you know what is your problem - you need to fix the drivers. Disconnect internet, uninstall current drivers, restart PC, and than install right drivers again
[G2 General] aftabalam8c2:
Most probably you get a screen with written download mode with give dots below download mode.

If thats u get..

Then its not download mode.

In download mode its firmware update written on screen
[G2 General] VladAndreMano:
Ive figured out the problem, but i dont know which version of the KDZ to get, im on a 16gb D802, i tried to insert my IMEI in the link but its just blank all the time.
[G2 General] LazyG:
actually any 16GB D802 would be ok.
[G2 General] VladAndreMano:
Thank you for the reply man, i really appreciate it

Also thanks to everyone that tried to help me, hopefully when the KDZ download is done ill be able to fix this mess.
[G2 General] LazyG:
btw, I think this piece of instruction is a little misleading.The issue is is that there are 3 devices in device manager, LGE Modem, LGE Mobile USB serial port and Portable Device G2, and COM setting needs to be corrected on device LGE Mobile USB serial port, not LGE Modem. It took me a while to figure out. The picture below shows the right device. Please correct.
[G2 General] hyelton:
The info in the OP is correct. Just recently it started showing "serial port" I think that's due to phones that have been upgraded to lollipop. Meaning phones that hasn't will still show lgemodem. It's both the same thing. Anything "LG" in ports there's only going to be 1 and that's what's needed.
[G2 General] efrengs19@gmail.com:
that´s exactly what i get!!

yeah!! i get a screen with written download mode with give dots below download mode.

Phone unable to connect, yellow arrow not working

Hello- first off, ADB is working. Second, whenever i try the kdz method, the program always says phone disconnected, replug again-- i do but the issue persists. when trying the tot method, it says everything is ready, but when i plug my phone in nothing happens. i've rebooted, reinstalled adb, found different firmware, and replugged several times, but the phone still says 0% in download mode, even after the flash tool saying ready overnight. i followed the steps meticulously- com is 41, phone in download mode, running flash tool as administrator, etc.
[G2 General] hyelton:
Wait... ADB is not part of going back to stock or this method..

So LgEmodem or LGE serial port is set to COm41 in device manager under the ports tab?

For the tot method when it says ready did you unplug and replug at that?
[G2 General] aftabalam8c2:
Its not download mode dear.

Main download mode shows firmware update screen on phone which comes after this.

Your phone is hardbrick.

You cant flash any kdz or tot.

It need to fix.
[G2 General] hyelton:
They could be confused. When placing any of them in download mode they will show that for sometimes up to a min before going into download mode.
[G2 General] suneel_b:
it's set to com41, but there's a caution sign on the icon of the device. when unplugging and replugging, does it have to be exactly at the ready?

thanks for your help.

No IMEI, but download mode

My phone lost IMEI during a custom ROM upgrade gone wrong. It is now bricked. Pressing all three buttons shows a blank IMEI on the white screen.

I can get into Download mode, but both KDZ and TOT method fails. TOT method starts but aborts because it says it is wrong model. It is supposed to be the D803, but in the log, it says Model Name : LG-L01F. What the heck variant is that?

I don't have EFS backup for this particular phone, but I have one from my other D803.
[G2 General] hyelton:
First of all if your phone was bricked you wouldnt have download mode.

an LG-L01F is a another variant of a G2. Which means the rom you flashed was MEANT for an LG-L01F.

What do you mean by KDZ method "fails"? if it says network error thats not failing its actually flashing.

Also for the TOT method the only way to fix that is download a hex editor and edit the tot file.
[G2 General] zhzhou:
Okay, to be technical, I'm not bricked. I'm just stuck :)

KDZ fails at 2% (as it usually does for me in this case). What do I have to change in the TOT? I'm comfortable with hex editors.
[G2 General] hyelton:

i need to fix it!! thanks!!
[G2 General] LazyG:
Sorry, can't agree, Just checked download mode right now - Modem is on COM6, Serial Port on COM3. And again, I spent 2 days trung to flash changing LGE modem, unsuccessfully, and than resolved it after changing LGE Serial Port. BTW, before setting LGE serial port, I had to change property of LGE modem to different port.
[G2 General] anonymous373:
Ok, so I managed to brick my phone. I still have access to download mode, but no recovery and my rom is not booting. I get error: Boot certification verify. I attempted to go back to kitkat from a stock lollipop rom using the kitkat partition patch. In the past it worked, but this time it did not. Would it be better to flash stock kitkat or lollipop using this method? Which is safer?

EDIT: I flashed kitkat 20H. Re-rooted and twrp installed. All is well again

my phone is showing nothing

my lg g2 d801 is stuck

it's showing nothing

i thought it was lg g2 d802 so i flashed it with indian 32 stock rom but then it went to fastboot mode because i forgot to put it in download mode

so i tried to get it back to normal by using lg firmware extractor and using the stock rom for lg g2 d801

and did all the things mentioned in the post but when i rebooted it using the command window it just went blank

it isn't even starting not even showing lg logo

and when i'm connecting it to my laptop my laptop is showing the dialog box asking to format the device

i don't know what to do now.

Hey, I have a rooted g2 vs980 32gb

I downloaded vs98026A_00.zip and all the stuff from the tot method instructions.

I am just trying to unroot and go back to how it was when I got it, just making sure I dont mess up.

Is there anything else I need to download? Or any chance I will brick my phone?

Sorry for my noob-ness.
[G2 General] hyelton:
As long as your following the guide everything is there. Just make sure you have everything backed up it does wipe it 100%.
[G2 General] helpakid:
Thanks for the fast reply! I will make sure I report my results.
[G2 General] Bud-Ski:
help

@ HYELTON

My apologies in advance, for my noob-ness, but my research has led me here as I see it has for many others too. I am here for the same reason- need/desperately/want to go bk to stock or the previous version of Android on my G2. Lollipop has quite frankly ruined my experience with my G2 :(

Basically reason why I am reaching out is bc I have somewhat of a unique situation. I have a Sprint G2 that I had put on boost mobile by a Boost mobile insider.. It was not flashed btw, it went from at power up the sprint spark screen to the way a normal boost phone wld look like when powering up and using. Not sure what they did. It was done all remotely over the phone. I did this last nite, well during the course of the nite, I got 3 Android system update alerts after I the phone became active on my boost act. The last being the Lollipop 5.0.3 version. And it blows!!

Ruined my nite as I was setting my phone.

So my question is- What files exactly would I use to go bk to the most recent version of Android that isn't Lollipop. I have never performed this b4 so some of the lingo is unfamiliar to me, although I am pretty tech/comp. savvy- Just really need to be pointed in the right direction. I am also worried about not doing it right and ruining the phone so..... Just want to make sure I am doing exactly what I need to prevent a major failure.

THANKS in ADVANCE!!

ANd I will surely buy a cple beers for the help and time :)

Oh btw here is the software version listed in the phone software info

LS980ZVG
[G2 General] hyelton:
So that's one thing I don't have exspeinace with is going back to stock on CDMA phones put on other carriers. If you use this to go back to stock you'll most likely need it reprogrammed. If you still want to just flash one of the latest firmwares in the OP for your model. Don't have the lollipop tot in there yet so you don't have to worry about that haha.

I haven't tested it yet, but lollipop on the G2 from say T-Mobile runs better than the G3
[G2 General] Bud-Ski:
OK I got ya, well in the event of, I can have it re-programed the same way I did b4 if needed. So in that case, What files would I need to download for my version of G2? I made a previous edit to the orig post w/ my software version. The ZVG. Would I use the files u have listed under the orig post for Sprint, or the new updated 2015 version towards the bottom of the post linked with the vid. I'm cool with flashing to one of the prev. of Android. Anything at this point besides LPop-
[G2 General] hyelton:
Yeah just make sure you flash your correct model. Yeah just follow the tot method and you should be fine ;). If you have any issues pm me and I can teamviewer it. But I cannot gurentee about the activation part though due to it being used on boost.
[G2 General] Bud-Ski:
Ok cool! :) THANK YOU!! And will do. Actually downloaded teamviewer last nite, but ended up not having to use it. Activation part, NP- I can get that done again if needed.
[G2 General] mdmaaat:
how long should this take on kdz method?

I wanted to flash back to stock lollipop on my verizon phone. The TOT method download was corrupt, so I go the kdz file. I got through all the steps, but the process is stuck at 60% now for the last ten minutes. It's now at 15:41 time elapsed and the percentage bar hasn't budged one bit...No error message has popped up yet. At what point should I be getting worried?
[G2 General] hyelton:
If the tot didn't download fully why did you just redownload it? All files in the OP are 100% and there's nothing wrong with them.

Close everything off , reboot phone and try again.
[G2 General] mdmaaat:
I did multiple redownloads but kept getting corrupt file. kdz seemed to be okay. I just retried doing kdz but now it keep saying the phone is disconnected once it gets a few percent in. One other thing to note: I keep getting windows explorer messages telling me I need to format the external drive (the phone) as soon as I plug it in. I get multiple messages like this as if multiple external drives are being connected. The TOT method requires doing something to change the com ports, but the phone never seems to show up in device manager either...

Thanks for your quick response and help.
[G2 General] hyelton:
Did you use a download manager to download the files? If not that can result in courpt downloads when downloading large files. Web browsers don't count as download managers.

Are you running windows 8? If so that can result in problems. As well as it not showing up in device manager/hidden.

When retrying the kdz method did you close out flashtool completely and reboot your phone?
[G2 General] smilesintears77:
Thank you for this. I have att d800. was on LP 5.0.2 stock, rooted with twrp. I didn't like LP much so I went back to KK using this method. process was smooth, no problem

I did update to d80020y too. thanks.
[G2 General] hyelton:
Your welcome :D
[G2 General] t3chn0s1s:
Long story short - I'm back on the G2 and I've run into an issue (nothing huge but still I'm concerned). I want to get back to stock or at least be able to but I now (for some unknown reason) I am unable to boot into download mode. I get the much heard about "secure boot error/certification" message in the upper left part of the screen while it simultaenously displays the "download mode" logo/animation thing after which it just reboots back into the OS. I have TWRP 2.8.6.1 installed and I'm able to boot into it just fine. I'm just worried about the download mode issue if for ever some reason I need to flash a stock image.

Anyone have an idea what the F happened or what this means? I've Googled a LOT and I keep finding pages that link back to xda to fix a dead G2 with the secure boot error - where it won't boot into recovery, download mode, etc. but that's NOT exactly my situation. I'm a bit confused but more worried about not being able to get back to stock if need the arises.
[G2 General] hyelton:
There'd be no reason download mode shouldn't work unless at one point something was flashed that wasn't meant too. Did you try and boot to download mode from twrp? Gotta screenshot or a picture of what happens?
[G2 General] oktheoriginal:
Kill me pls

Ok. I have been stuck for over a month now and so here is the full story:

I have a g2 D802. I got it and I didnt mess about with it. But then I was an idiot and updtaed it through LG software update tool. This thing killed my phone. It installed lollipop and I then had these issues:

[1]no imei.

[2]no baseband.(FIXED)

[3]touch is not working properly. It is haywire. It does not respond properly at all!

[4]no sim usage as no IMEI.

[5] ONLY 16 gb showing as memory available. (FIXED)

I did this.Using OTG to use my phone, I flashed stock d802 ROM (kitkat). This got me to Stock ROM but boot looping. I factory resetted and it started up okay. I then found a way to fix the 16 gb issue by using a droid view guide called : "Your 32GB LG G2 Shows only 16GB Storage Space? Here’s How to Fix the Issue! " This fixed my 16 gb issue. But everything else same... Then I followed a guide to fix ESN but it demanded that the phone be rooted. So I rooted and installed TWRP. But I was not able to fix IMEI. So I then gave up I searched my issue extensively and found a thread (ON XDA) which i cant post here... :( But its name is: "Strange touch problem after upgrading my lg g2". There I read of other people who had the same issues. This basically happens to refurbished handsets apparently. There where no proper fixes there. None of the people where able to fix their phones.

Some guy said that check your motherboard and install the software according to the motherboard. I opened the board and found it to be a motherboard of LG D801. :confused: No problem. I downloaded D801 software and tried installing with kdz method but it failed. And now so has the tot method. I have downloaded over 13 gbs of software and roms. I have given up. Please please help me out...
[G2 General] hyelton:
First of all your having this issue due to flashing the wrong firmware. Especially seems you also had flashed a wrong size one too.

Anyway what do you mean by when flashing the D801 it failed? That doesn't explain much. When using the kdz method it give give an "error" but if you move it you can actually see it flashing.

As well as did you use a download manager or not? If not then your kdz file could be courted and cause it to fail.

Also with the tot method did you change your LG com port to com41 in device manager? If not there's your problem with that.

Or did you get wrong model? If so then you'll need to do a hex edit on the tot file.
[G2 General] Soufiansky:
T-mobile lollipop firmware is only 1.1GB ?:confused:
[G2 General] hyelton:
Huh? Where do you see that it's 1.1gb?
[G2 General] Soufiansky:
On your download link. T'mobile , lollipop , 30b firmware is only 1.1GB ..

It's the last one ( 1st April 2015 )
[G2 General] hyelton:
Then I guess it is. Forgot that I had lollipop link for the T-Mobile variant. (I keep up with tons of models)
[G2 General] Soufiansky:
Don't you know why it is small compared to others KK .kdz firmwares ?
[G2 General] hyelton:
Maybe more optimized? Who knows lol. LG makes them.
[G2 General] Soufiansky:
Thanks.( god you were so fast , answered me in the same minute :D )
[G2 General] hyelton:
Depends on when I have my phone in hand:) I try and keep up on every notification I get, have had a busy week which is slowing down finally.
[G2 General] Soufiansky:
The phone stuck in 14% and keep restarting over and over .. :(
[G2 General] hyelton:
What's the error?
[G2 General] Soufiansky:
I managed to flash it but it keeps on Lg logo with blinking led and restart over and over. I went to recovery for factory resest , did it but it doesn't work..
[G2 General] hyelton:
Thats odd, Yeah I checked the file is full and correct.

Did you try flashing after it flashed fully?
[G2 General] Toonlinkmaster25:
No matter what I do I can't get the LG drivers to install. Any download I use with the installer hangs at the very end and I have to force close it. I've tried uniinstalling it but my theory is that it is not uninstalling all the way. I'm using a relatively new computer on windows 7 professional btw. Please help my phone is just a few steps above a paper weight right now.
