KitKat the EASY Way!!!!
Or, go back to 4.2.2 JellyBean

If you are going to return your phone back to warranty, I would suggest this method in this thread as it does a COMPLETE wipe of your device and puts it back to 'Factory'. It removes Root Flags so it does not show having been rooted, and removes ALL data.

Disclaimer: This is not MY method, but a method I used. The information and files have been figured out over time by many individuals and it's been combined in this thread.

This thread is to help Noobs AND Veterans to flash their ATT D800 LG G2 to KitKat. This will be very spelled out, and I’ve even included a video (see below), so NO Mistakes. Yes, that means you! ;)

PLEASE refer to the Video Below before asking questions, as too many questions get a little overwhelming.

Warning! Please Read!

This WILL erase everything on your phone and put it back to FACTORY STATE, so be sure you’ve backed up!

Ok, first thing you need to do is download the version you want. I’ve got KitKat 4.4.2 version D80020c, and I’ve got JellyBean 4.2.2 version D80010o. These are VERY LARGE files, so be patient, although I am able to get as much as 6MB/s download speeds from this server.


Download Installer - KitKat 4.4.2 D80020c - This Flashes Stock KitKat, WITHOUT Root, and WITHOUT Recovery. - Use TowelRoot and AutoRec to get Root and Custom Recovery. - Single File LARGE archive. KK MIRROR DOWNLOAD
D80020c Split Archive Download - This is the same archive as above, but split into smaller pieces for easy download.

Download Installer - JellyBean 4.2.2 D80010o - Single File LARGE archive. JB MIRROR DOWNLOAD
D80010o Split Archive Download - This is the same archive as above, but split into smaller pieces for easy download..

Download Installer - JellyBean 4.2.2 D80010d - This is for those who want to install Custom Recovery and not update to KK... - Single File LARGE archive.

Now, for the fun stuff (You may want to print this out for reference and check them off as you go)

Pre-requisites:
1. Be sure your phone is currently running a Compatible based ROM. If not, please flash a Custom Compatible Based ROM onto your phone. (ie: If you have a D800, be sure you have a D800 ROM on it. If you have a D802, be sure you have a D802 based ROM on it.)
2. Be sure you have turned on USB Debugging before starting.


Step #1: Program Installation:
1. Save the installer to your desktop
2. Run the Installer by double clicking
3. Wait a while for everything to extract (It might look like nothing is happening. This can take a few minutes, be patient, it’s HUGE)
4. (On Win7 or Win8, Accept User Account Control)
5. Accept my License
6. Don't Change Anything and click ‘Install’
7. Wait some more… and more… Large files are extracting…
8. When it pops up, click ‘Next’ to install the LG drivers. Even if you’ve already installed them, install again! This is to verify you’ve got the right ones installed.
9. Click ‘OK’ to finish the Driver install
10. Click ‘Next to install the LG Flash Tool
11. Don't Change Anything and click ‘Install’
12. Uncheck ‘Run LGFlashTool 1.8.1.1023 and click ‘Finish’ (If you forget to uncheck this, just close the program when it opens)
13. Click ‘Next’ to start the LGFlashTool Patch. (This makes it so you don’t need to change the date back on your PC)
14. Click ‘Next’ again
15. Click the bullet to ‘Agree to my License’ and then click ‘Next’
16. Don't Change Anything and click ‘Next’
17. Click ‘Start’
18. Click ‘Next’
19. Click ‘Exit’ to finish Patch Installer
20. Congratulations, Program Installations are all DONE!

Step #2: Place Phone into Download Mode:
1. With phone NOT plugged into a USB Cable, Hold the Power button to turn off phone
2. Plug your USB cable into your computer
3. Hold the Volume UP Button on your Phone
4. While Still Holding the Volume UP button, plug in the USB cable to your Phone
5. Continue to hold the Volume UP button until your phone enters Download Mode
6. If this does not work, pull the USB cable and start from #1 of this section

Step #3: Change Com Port to 41
1. With your phone STILL in Download Mode and STILL Plugged into Computer
2. Go into Device Manager
---a. Press and hold your Windows Key (Between CTRL and ALT)
---b. Tap the ‘Pause/Break’ Key (Usually Top Right of Keyboard, might be different on yours)
---c. Click on ‘Device Manager’
3. In the Device List, scroll down to ‘Ports (COM & LPT) and double click to expand
4. Find the ‘LGE AndroidNet USB Serial Port (COM4)’ (Your COM Port Number might be different, that’s OK)
5. Double click to open the port
6. On the Tabs at the top of that screen, click on ‘Port Settings’
7. Click on ‘Advanced…’
8. Click on the Com Port number to drop down the list
9. Scroll down to ‘COM41’ and select it
10. Click ‘OK’ Button to save that
11. Click ‘OK’ Button to close the Com Port Properties
12. Close the Device Manager
13. Close the System Window
14. Go back to the Desktop
15. That’s it, You’ve Changed the Com Port to 41

Step #4: Run LGFlashTool:
1. Double Click the ‘LGFlashTool’ icon on the Desktop (Win7 or Win8 accept ‘User Account Control’)
2. In the ‘Model Config’ window, check the box ‘Select Manual Mode’
3. Next to the DLL space, click the Three Dots ‘…’
4. Select the DLL file named ‘LGD800_.....v160.dll’
---a. For 4.4.2 KitKat, select ‘LGD800_20130811_LGFLASHv160.dll’
---b. For 4.2.2 JellyBean, select ‘LGD800_20130904_LGFLASHv160.dll’
5. Click the ‘Open’ Button
6. Next to the S/W space, click the ‘Remove ALL’ Button
7. Next to the S/W space, click the ‘Add’ Button
8. Select the tot file for the version you are flashing
---a. For 4.4.2 KitKat, select ‘LGD800AT-01-V20c-310-410-FEB-02-2014+0.tot’
---b. For 4.2.2 JellyBean, select ‘LGD800AT-01-V10o-310-410-OCT-19-2013+0.tot’
9. Click the ‘Open’ Button
10. Click ‘OK’ Button to save choices
11. In the LG FlashTool program, click the ‘Yellow Arrow’ pointing to the Right.
12. Wait for the program to verify your DLL and TOT selections (This takes a while)
13. If successful, you will see ‘READY!!’ on ‘Port 1 (COM41)’
14. If you DON’T see ‘READY!!’, you may need to start over
15. If you see ‘READY!!’ unplug your phone from the USB cable and Plug it right back in. DO NOT PRESS ANY BUTTONS ON YOUR PHONE. It should STILL be in Download Mode.
16. The LG FlashTool progam will now start flashing your phone!!
17. At around 80%, the program will restart your phone.
18. It takes a while for the phone to restart, but it will boot to Android. Wait for the flash program to finish and it will turn your phone back OFF. And give you a ‘SUCCESS”
19. Close FlashTool

IF for some reason, the LG FlashTool does not finish 100%, and you get a ‘Fail’, as long as your phone has now rebooted into Android, you don’t need to worry about this. Just close the program, and enjoy your Freshly Restored LG G2!


For anyone having issue with the device check not passing due to mismatched device (caused by flashing a Custom ROM with Different device model ID to your D800: ie, D801 to a D800 or vice versa.), try using the attached dll file instead of the device specific one. It has been reported to work for many... You will need to extract the zip file to get the dll.

Just so you know, in step #4 you have 4.4.2 twice ;) But great job man! You might want to use the 10d 4.2 as that is the one that recoveries work best with. Just a thought.

What variant is the 801? Sprint, Verizon? Sorry, on my phone at the moement.

EDIT: Doh! Now I know what you meant... Sorry...

Thank you for that. FIXED. ;)

EDIT: Why is 10d easier? Is it due to the script in ioroot22? I keep flashing 10o, then use ioroot22, then use FreeGee to install TWRP. Easy Peasy. BUT, I might have modified ioroot22 script for that, I don't remember ATM.

I haven't had my G2 very long so I haven't been able to test myself, but just looking around the forum seems the 10o firmware causes boot issues with some custom ROMs. I could be wrong though. Maybe the problem doesn't exist anymore and I'm reading old info.

Ioroot and then freegee TWRP route works on 80100o. Unfortunately, flashing ROMs (stock based and flex based especially) causes issues. I do not think anyone figured out the reason but going to 80100d solves the issue.

So I understand... If you flash Stock 10o, then Root and Flash Custom Recovery, you have issues flashing other ROMs? But if you Flash back to Stock 10d, you do not have issues flashing Custom ROMs?

Also, FYI: ioroot23 was just released... I don't know if that will make a difference. It has 10o support built in.

Yes that is correct.
I am not sure if rooting was an issue. It was the recovery that seemed to be the issue. Not sure though and I guess since 10d worked not many people bothered to investigate further.

I'm having the same issue flashing any stock based rom on 800o. It throws me in a bootloop. How would I get the 800d fw?

i can confirm this is true. i lg flash tool'ed back to 10o, while i could get root i couldnt get twrp or philz recovery to work. when i went back to 10d with lg flash tool, i could get root and recovery to work. i even loki'd a couple recoveries and the recoveries wouldnt only give me a black screen when i tried to enter them on 10o. and i used ioroot23 to do all of this with.

Is this tool safe to use if the phone shows rooted after you go into download mode? Although I swore I unrooted the phone.

Took a chance and did this anyway and all is good. Upgraded successfully! Thank you so much for providing this tool! It was such a pain searching for a serial for lgflashtool. Will be donating asap for the help. Thank you thank you thank you. Directions were perfect as well and very easy to follow.

Sorry Everyone, I've been out of town and only on my phone, but mostly busy with family stuff.

Thank you for the clear info. I will build a 10d version. Hopefully tomorrow.

I'm sorry, I have been away from home. Just read this. Yes, you are fine if your phone is rooted. This Flash will remove Root. As mentioned in the First post, there is currently no way to root KitKat, (Unless I've missed something since last night). So root, then go to KitKat.
Downloads not working for me... 68% complete is furthest I've gotten. Tried seven or 8 times.

Some people have issues with Internet Explorer on Mega Website. You might install Chrome or Firefox and try it that way, or use a Download Manager of your choice.

That is Correct, no Custom Recovery. Not unless something has appeared since last night when I last went through the forums.

Usefull guide :) thanks :)
but i think there is not a difference between those Flash DLL i had 20130904 and just freshy flashed KitKat
also if anyone cares about a LG Flash tools "PASS" then while it stops on 80-94% and boot into OS itself, do a Factory Reset of phone and it will check a Factory Flag (it sets to 5) and gives message a PASS

    New Installer for D80010d

    I just finished the installer for D80010d. It's uploading now. I will update First Post with new links when it's done.

    I'm using Firefox (on phone too) with the Mega addon and I have not had problems in past.

    I'll keep trying.
    I just created a new archive that is broken into 20 Parts - 100MB ea. Download all the Parts to the same directory, then run Part01. It works exactly like the Single File Download, but is much easier to download for those having issues.

    You will find it HERE, and also linked on the First Post. Uploading now, and may take a few minutes, so please verify ALL 20 Parts are there before you download.

    Can u tell me where can i get .tot file for D801 T-Mobile?
    I don't know where to find the TOT file, but you can get the LolliPop KDZ file from @hyelton over here: http://storagecow.eu/Xda/LG G2/Stock/T-Mobile G2/Lollipop/D80130b_00.kdz

    And a good tutorial and program needed here: http://forum.xda-developers.com/showthread.php?t=2432476

    can i do this on my lg d800 with cm12 installed with twrp recovery ..
    can i install it on my device using this method?
    As long as CM12 is a version specifically made for the D800, you can use this method. It will remove TWRP and CM12 and put stock Firmware on your phone.
    EDIT: If the version of CM12 is not specific to the D800, you can flash a D800 based ROM before using this method. Also, remember to back up. EVERYTHING will be wiped.

    Super
    Do i have to start all over? Or should/can I run ioroot23 again?
    I think i recall that install giving an error.
    If ioroot23 gave an error, then it may not have stuck. If that's the case, and you are already in KitKat, then there is no way currently to add Root. You will need to flash back to JellyBean and Root there.

    Have you flashed Custom Rom's before? If you have, and you know that method, I would recommend these steps.

    1. Flash to JellyBean D80010d or D80010o, whichever you currently have on your computer.
    2. Use ioroot23 to Root JellyBean. VERIFY Root using Root Checker from PlayStore.
    3. Use FreeGee from PlayStore and select TWRP so it installs TWRP.
    4. Download and Flash the D80020c ROM from http://forum.xda-developers.com/showthread.php?t=2665391 - FOLLOW his Directions Carefully, Flash the ROM, and Be sure to flash SU BEFORE Rebooting!

    You should now be on KitKat WITH Root. But, there will be NO recovery yet. The Dev's are still working on that.
