My Lg g2 d801 got some sorta weird glich on it after i used some app called force media scan and i hoped flashing back 2 stock would help but it did not . I tried factory reseting from unofficial cwm and twrp and original recovery nothing got rid of the glich that makes my phone reboot every 20 seconds on its own . Does anyone know of any other way i can wipe my phone ?

Try an hard reset

OP, thank you so much for the instructions for going back to stock. I am a Sprint customer and followed your instructions exactly. Was able to get a used G2 I purchased totally back to stock and then it immediately upgraded successively to ZV8 and then to ZVA. Your process worked without problems and I now have a fully functional clean G2. Only problem I had was the time it took download the stock rom. It took almost 3 hours. Thanks for your work.

Your welcome :) be sure when downloading anything larger than a GB use a download manager. My server is on a 2GB port so it has plenty of bandwitdh to go around lol.

dude ive tried numerous times with the same results. that is not a fix

There's no fix. Only 2 things is reset and make sure it shows the exact same phone and model as the phone and firmware are. You must be running the firmware that came with the phone / carrier unlike with Samsung devices. The resetting worked for me on both the g2 and g pro.

what came with the phone was the 10d. i have done this many times with success and now it just doesnt work. i can confirm without question that this method works but does not let you update. there for it is no longer a factory reset. it damages the phone once you are rooted and rom'd. gonna try and trade my G2 for a nexus 5 or just buy another phone cause this phone i am starting not to like already. it was cool 3 weeks ago,but,the hype is over and i am over this phone.

Its the SAME guide about it as the OP... Also this person seems to just need to do a reset using the correct volume and power key combination. Its gonna bootloop ever after flashing in some cases if you don't reset it..

Hi Hyelton,

What's the correct volume and power key combo for the korean versions to reset the phone. Thanks.

    [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!!!!

    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

    How to Flash YouTube Video:

    (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
    5.Copy MegaLock.dll file to C:\LG\LGFlashtool (This might be a hidden folder so enable "hidden folders". Replace the old MegaLock.dll file)

    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.

    13.Now Click the Yellow Arrow Button at the top left, The Firmware install will be triggered
    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
