On the Korean models I wouldn't recommend flashing anything other than Korean firmwares people have had issues with other phones like the G2 when doing that. Also NO OTA updates.. The only way to get OTA updates on LG phones it HAS to be running the exact type of firmware the phone came with AND registered with your carrier as the exact model of your phone and IMEI. The update basically only happens if the IMEI matches LG servers with your model and carrier.

    So The poster who posted some of the other G Flex files for going back to stock the threads were closed so I could not update it with new links. I have obtained some more KDZ for different models in Europe now :) The KDZ`s are some what hard to get for the G Flex but I was able to get a few extras :)
    Below is a Guide that has worked on Flashing the other LG phones it should be the same for the G Flex :)

    NOTICE! - IF you download fails or does not download all the way USE A DOWNLOAD MANAGER!, Files that are usually over 1GB browsers have issues downloading them especially if you have a slow connection.
    NOT Responsible if you flash the WRONG one

    Normal Flash: Flash ROM without losing any data. Only use this when you need to fix system error. Beware of boot loop when flashing ROM that differ from current ROM on your phone or MOD ROM.
    CSE Flash: Choose this option when you need a fresh format. All data will be gone. It's suitable for upgrading or downgrading ROM or simply use this when you need to back to Stock.

    3. Extract the TOT file from the ZIP

    When LG Flash Tool is installed, do not launch it.

    7) Copy MegaLock.dll to C:\LG\LGFlashTool, This is a hidden folder so enable "hidden folders". Replace the old MegaLock.dll file if you have already installed LG Flash Tool on your computer.

    9) Launch LG Flash Tool.

    You might see a window with Korean language, just click on OK.

    Check the Select Manual Mode on the top.

    11) Click the DLL box and choose the dll file from above for you phone model.

    12) Click the S/W box and select the firmware file with .tot extension.(the 2.04 gb file from above)

    13) Now click the Yellow arrow button on the top left of the main window.

    The firmware installation will be triggered.

    Ignore if you see any temporary error and just wait patiently till it is finished.

    Do not close the Flash Tool window.
    14) Press and hold power button until phone turns off, leaving usb cable connected to device AND computer ,immediately hold volume up button until phone boots it into Download Mode.

    Your LG G2 will restart showing firmware installation progress in percent (%).
    When all is done, reboot your phone and enjoy!

    Remember if you have bootloop or stuck on LG Logo after flashing make sure you FACTORY RESET!

    Extra Important Info:
    To Fix ANY Driver issues make sure you reboot your computer after removing and then reinstall again, Also try different USB ports or USB cable or try another PC.

    WARNING!!!

    WARNING!!! DO NOT PAY to download TOT`s or KDZ files! Not sure if anyone here has before, but I found a link for the latest V10I AT&T TOT and I clicked request permission and I was greeted with an email from someone asking "Who is this" followed by another emailing me to send $30 to there paypal account for the link. So NEVER pay for any files. These files at one point will be available on my server and other places. So just a warning to save you time and money don`t fall for these idiots.
