nvm, i got it fixed..

turns out, i was trying to use half-downloaded .kdz file. (with only 900Mb)

i feel so stupid right now :*(

by the way, i don't understand what op is saying by

" Be Sure that after flashing to perform a reset as for some reason flashing this does not remove what was there before until you reset. By turning off, Holding down power and Vol Down until it comes up on the screen."

can someone explain this to me as if i was 5 years old :p?

Flashed the UK version of 80210A and I got it to boot!!!

Unfortunately all of the touch screen etc is not lined up so nothing seems to work..

I did a factory reset with no help for the issue..

Going to try and reflash th Tmo KDZ now..

Happy I at least got it to boot!!


edit..


Tmo KDZ continues to freeze at 49%.. However I now show unrooted in download mode...

I reran the LG utility and now it recognizes my phone as the D801 which is correct.. The software still shows D802 due to the UK install..

Now when I run Upgrade recovery it actually is downloading within the LG software which is a first...

Things are looking up!

I am not sure why it was the UK D802 that brought it out of the sh!t storm I was in!

:)

OK, I was finally able to complete the download and return to stock. For anyone else that was having issues with "page error" for me it was an incomplete download. T-Mobile firmware D80110C should be exactly 1.72gb once its complete.

No one should go by this..... Not all of the firmwares are the exact same size! Some are larger and some are smaller

Why you think it's Windows 8?
Page error in tools log is allways shown in any/most cases of an error.
I get it on Windows 7, also. Not exactly sure why.
Only the Debug prints (use DbgView for example) shows the real error.

Thats a link on my server, NOT LG`s... The Asian rom is now gone. Thats why that link is like that on my server I put it there for reference in case it ever came back..

Hi, Thank you.
It look like you just short url to direct the click to Mod Edit: Broken Link removed
And the file still there ! But could not download. Can you up it again to your server ? I only can download 10 to 20% of the file and it stop, for the last few days :(

    [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]

READ!!! The first Guide Below is to Return To STOCK For ALL Varrients!! EXCEPT for the AT&T Please read below for the steps to return to stock on AT&T

    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
    First off I`d like to THANK @quangnhut123 for making a new way & easy way to flash the KDZ Method!!:)

    The Files are Hosted on my server for fast speeds! Most if not all NEEDED KDZ files are on my Server :)
    1). Download all The Files Below!

    1) Firmware Files - HERE!
    Or Here LGKDZ.com for your exact match KDZ for your model

    (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.

    (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

    4.Extract the TOT file from the Zip

    10.Select Manual Mode at the top
    11.Click The DLL Box and choose the DLL file from Above meant for your device

    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
