I do have E988 as well and was on CM 11 before when I encountered a bootloop. What i did was i used LG Mobile support tool directly and that did the trick. Were you trying to flash using KDZ method? Because i also tried doing that and i received ths same error as you had

KDZ

Yes, I am using the KDZ method. Using the LG Mobile support tool just shows that the phone is updated. Is there any other way on using that tool?

For the "Upgrade stopped due to an error", I had just struggled with it for four hours, and won. I believe it could be that the kdz file had been corrupted during downloading, then I remember that I have an older version kdz, choosed it then voila, I'm back to stock.
hey in download mode you can not flash stock rom the kdz is not corrupted i have same problem and i have tried different versions of kdz but non of them worked
ive got the same problem, so is there any help for that?

Hi, I was searching info and I found this, i don't know if can work to solve the download mode problem reflashing the firmware. http://www.lgmobile.co.kr/lgmobile/front/download/retrieveDownloadMain.dev Where it says Optimug G Pro Upgrade, click in the option "U+" that is the AKA of the F240L. I don't understand the characters, it seem korean or something like that, but there it is a info about the LG Suppot tool, i think with this program can download the tot file or flash directly with an internet connection.
I was searching for a kzd flash for lg optimus g pro series but i can't found a easy software tool for this purpose. But in this link is the KDZ Firmware files for your version http://lg-phone-firmware.com/index.php?id_mod=25

You just destroyed your firmware, hope you back up your phone regularly because every data on that device is now gone. On the brighter note, since you know how to flash the rom, all you have to do is flash the device correctly and you should be good.

flashed tmobile firmware on and ls980 g2.. can i fix it? please help

I flashed a stock 4.4.2 t-mobile firmware to my sprint ls980.. is there anyway to get any ls980 firmware back on it? i use it for tmobile which is why i flashed it but seen a few threads on how to unlock the sim and now im stuck. did i ruin the phone? or could i at least get it to work through tmobile with the firmware i flashed? i cant even get it to connect to google play. wifi works tho
Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck
First: Grab the ZVE Tot file
Second: Flash it in download mode.
Good luck, flashing in download mode is rather a pain to do.

There is a DLL file that is generic that should overcome that problem.
Facing the same problem..please help
I've also done the same thing just a little bit different.
i flashed D802 (international version) kdz file over my sprint g2 (Model is LS-980) but it does not work, when i turn on the phone I can't even complete the setup and the phone restarts. touch panel is also not working right.
Now i've downloaded the stock .tot rom for sprint version and trying to flash it using lg flash tool in download mode. But it does not flash it. It detects my phone as D802 and gives the error about the model number does not match
I need help getting it back to LS-980

Supposedly there's a stock .kdz which I can use to extract the .dll from, but I haven't found any stock .kdz file so far.
So, this generic .dll sounds great and one of my last options left. I'll appreciate if you can point me to that file. I'm going to try to find it.
Thanks a lot!!! :good:

I've tried this .dll file with both the stock ls980zvc and ls980zve .tot firmwares.
but the flash tool gives this error "CrossDL [D802] to [LS980]. SWversion"
Is there any way around this?

Hey..
I have exact the same Problem while upgrading to 7.0 via tot File. After update stucks after 21% and get same error - 0x2000 invalid command response.
After Battery pulling i´ve used LG Bridge in Software Update Tab and use Correct update error, but LG Bridge tells me there is no Update Error, my System is up to date
I changed some LGUP 8994.dll files, there are some out there...nothing is working.
Try to "downgrade" H81520D_6.0.00_0115.kdz via LGUP, but after 21% it fails too.
So, what next ? Any one a working Idea for me ? Thank you.

LG H815 - error on every firmware
Hi guys,
I have same problem, already been through all the solutions that I have found, including H81520p_00_0314.kdz and replacing DLL from this firmware. Still got error 0x2000 :/ Any ideas? I have checked mainboar and model is H815 without any letter after.
OK, some update - extracting DLL helped, I can flash firmware, but phone stucks on LG logo and don't want to boot up :/
Hello,
Thank you so much, this method worked - H81520p_00_0314.kdz.
Now how can I install another version of android 6, which is officially in Romania? I honestly do not know which version I should install! (V20?-EUR-xx)?
Please give me all the steps to follow to install an official version.
Thx.
PS: my phone is LG H815 International version, Carrier less.
