You should perform a factory reset before getting back to stock. That's what I did and it worked out pretty well

i did in cwm but i was on a kit kat based rom at the time. Wouldn't work. Flashed a stock based LG rom and tried again and it worked no issues. Seemed odd but oh well.

Weird. As I was also running cm11 and Omni ROM. But I was running TWRP recovery, and I wiped everything before flashing the stock firmware as described in the OP

hey guys, my phone screen has been pretty glitchy, the bottom quarter of the screen moves up and down rapidly from time to time.

does anyone know of this issue?

anyway was thinking of restoring the phone to stock to return for RMA

doing this will remove any trace of root & make it eligible for RMA right?

kindly advise.

thanks guys!

soft reset

I didn't hard reset my g2 at the time but did factorysettings/soft reset instead. Is that good enough or will I get bugs like this?

Thanks gkarntasi mou!!!

Netherlands OPEN D80210F_00.kdz
Germany OPEN D80210E_00.kdz

They have differences??? F from E???

There's also a UK 10F. I don't know what the differences between european versions of E and F are, BUT, it seems that the countries that went from A to E did so earlier than the countries that went from A to F. It might be logical to assume that the big KitKat update will be seeded first to the "E" countries.

    [CENTER]Common Questions and Problems KDZ Method:

    1.Network connection error is NORMAL, move the window over and you'll see its actually most likely flashing

    2.If your getting errors when doing the kdz method and running a custom rom that could be the problem and you'll need to use the TOT method.

    3. Getting connection errors? Check under device manager to make sure you see LG something related under communication ports (Windows 8/10 ports might be hidden)

    Make sure your using a USB 2.0 port!! USB 3.0 will NOT work.

    Common Questions and Problems TOT Method:

    If having an issue try and choose Board_ID on the TOT/DLL selection screen.

    Make sure you've set your COM port to COM41

    If device does not start flashing besure you unplug and replug the device

    Make sure your using a USB 2.0 port!! USB 3.0 will NOT work.[/CENTER]

    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 espseically if you have a slow connection.


    First Off Not Responsible if you flash the wrong one!!!!
    Please Check to make sure you don`t flash a 16GB firmware on an 32GB device. Please check the file names if they have an "16GB" in the File Name

    THIS Guide Below for All Versions EXCEPT the AT&T Version (For AT&T & Sprint Scroll Down more)

    How to flash ROM KDZ Method

    (If you cannot run LGFlashTool2014.exe, please install Visual C++ Runtime Library) - Download HERE
    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.

    2015 (updated with pictures) TOT Method!
    RETURN TO STOCK TOT METHOD!, AT&T, T-Mobile, Sprint, Verizon, & a The few International TOT`s that are available

    (Hint) If your getting wrong dll/Wrong model error after having to start to flash and it fails use this DLL file instead of your model DLL file: LGUP_8974.dll - 1.4 Mb
    This error means you where running a rom not meant for or built on a different model#.

    Install:
    2.Install LG Drviers
    3.Install Flashtool (Don’t run it yet)
    4.Extract the TOT file from the Zip

    9.Run LG Flashtool as Administrator
    10.Select Manual Mode at the top
    11.Click The DLL Box and choose the DLL file from Above meant for your device
    12.Click the S/W box and select the firmware file with the .tot extension, Then Click OK when done.

    4.JPG

    14.You may need to unplug/replug phone before Firmware install will start (If it does nothing after clicking the yellow button


    15. Should take anywhere between 4-8 Minutes, When its done your phone should reboot

    Do NOT Close the FlashTool Window during firmware update.

    99% of the time FlashTool will FAIL after 85% anything after 85% is just your phone rebooting so your safe :)


    _____________________________________________________________________________________________________________________________
    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.

    LGUP Method:​
    Flashes both KDZ & TOT files:
    Thanks to @shakeyabooti for LGUP!

    Download LGUP from HERE
    Install the file with the DLL name in them first and then LGUP_Install_Ver_1_14_3 Then copy the folder "common" to C:\Program Files (x86)\LG Electronics\LGUP\model (this should resolve unknown error)
    Make sure you have downloaded the required KDZ file MM or LP
    Open LGUP on your computer "make sure your phone is plugged in"
    ARE YOU HAVING TROUBLE WITH LGUP NOT SEEING YOUR MOBILE?
    Try this....... take the back off your mobile so you can get at the battery. Connect your mobile via USB. Start LGUP, if it does not see your phone DO NOT DISCONNECT, DO NOT RESTART OR TURN OFF LGUP. Take out the battery and then put it back in.......let the phone restart on its own. LGUP should now see it.

    LG Drivers: in First post

    TO DO A FULL WIPE AND INSTALL MM - Open the LGUP on your computer. FILE PATH point it towards the MM KDZ.
    IMPORTANT!!!!!!! shut down LGUP!
    Now open LGUP again - you will notice that the MM KDZ will still be showing in the FILE PATH section. Select REFURBISH and make sure BIN file is ticked. Press Start. Make cup of tea and be patient

    TO GO BACK TO LP FROM MM - Open LGUP on your computer, click on FILE PATH and point it towards your LP KDZ. Close LGUP and re-open LGUP. Make sure you select REFURBISH this will do a FULL wipe, tick BIN file. Press Start. Make cup of tea and be patient
