[Q] Restoring Korean F240 To Stock

Hi Guys
I flashed the CN mod rom on to my korean f240k a few months ago because i wanted to remove the subscribed network notifcation but now ive decided i want to go back to a stock rom.
I have tried to run the restore on the lg support tool but they have updated it and it doesnt seem to work now, also the flash tool doesnt open on my windows 8 laptop..
Is there any other ways of completely resetting the device?

Easy, put your imei number instead xxx it the link http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=xxx and you'll see link to latest KDZ ROM file for you F240K. Download it, find KDZ_FW_UPD_EN somewhere here and flash your KDZ onto phone. You're fixed!

imei should be straight bunch of digits, 15 in my case, without any dashes - or qoutes " or `
it must work, this way your phone connect to update servers and downloads it's updates

Nothing works on windows 8.. Even in compatibility mode

I am tried that flashtool 100 time todays and it was getting stuck at same OnStepMsg STEP_TYPE_ENV_ERROR delete m_pLGCyonUpdate error. I read it some where that LG's pc software can recover phone it does same thing as flashing the stock rom for your phone. I am trying that its currently downloading the firmware will take around an hour to download as file is 1.8 GB. Will post back if it goes well.

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?

Hello there,
I have the same problem with my G3 D855.
I send it now but at the LG customer under warranty.
Let's see what it comes out.

Fixed by doing the shorting method. Flashed v10* instead of MM like I was supposed to, but I got to download screen and reinstalled MM

Hey, please share the outcome.

Hey ho,
I'll keep you posted.
The support has now sent me the repair order and the shipping label to the next repair service. On Monday my G3 goes on tour.
Hopefully it is then end of the week back.
As a repair base I had given an update error. Which was caused by the "LG PC Suite" program.

Hope this helps

Hello there,
Yes, the way I have already looked at.
But I have warranty on my G3 until the end of 2016th
Since I try only so dear, and when LG says no because then I try this out.
Would not be the first mobile phone which you have to open and to repair it ^^
