Update LG G2 to Android 4.4.2 KitKat without Losing Root (D800, D801 and D802)

update-lg-g2-to-android-4.4.2-kitkat

Android is the greatest ecosystem for mobile devices but among things of “WOW” there is a great disparity of distribution that is certainly not a good thing. Android is the only OS with multiple OEMs who theme and customize it with their own flavor. This variety is probably the greatest reason behind the time-gap between the pure AOSP updates released by Google in Nexus devices and the customized updates for device from other brands.

It has been more than four months since the time Android 4.4 KitKat was released but the new flavor of Android made its way to device from OEMs like HTC, Samsung, Sony and LG after months. As a flagship phone, the KitKat update turned its face to the LG G2 rather late. Anyway, the Android 4.4.2 update is finally out for the device. Following the Open LG G2 and AT&T G2, the T-Mobile variant started receiving the official KitKat.

If you own the awesome G2 and have rooted and install TWRP/CWM recovery on it, you’ll not be able to receive and install the OTA. For users with a custom recovery, downloading the KitKat firmware using LG Mobile Support Tool and installing it manually might be the only way to get the new update working on their device. However, flashing the official firmware with .kdz or .tot extension will remove the root and custom recovery both.

The bad news is that there is no working method to root the LG G2 on the Android 4.4.2 KitKat firmware. And, the good news is that, if you own any of the following models of LG G2 with root and TWRP/CWM recovery, there is still a way to preserve root on the device.

  • AT&T G2 D800
  • T-Mobile G2 D801
  • Open LG G2 D802

Today, we have come up with a way to update LG G2 to Android 4.4.2 KitKat without loosing root privileges. Please note that having installed the stock firmware, the TWRP recovery will be replaced with stock recovery.

T-Mobile-LG-G2-KitKat

Requirements

  • LG G2 D800/D801/D802
  • Root access and TWRP Recovery version 2.6.3.3 or higher.

Note:

If your LG G2 does not have root access and a custom recovery, you can install the Android 4.2.2 KitKat firmware manually by following this tutorial.

    Im having a hard time downloading the files needed

  • http://www.droidviews.com/ Rakesh

    Thanks for sharing your experience, Yaroslav!

  • Yaroslav Funt

    I don’t know how I did it, but I somehow unlocked my phone after many tries.
    I have Kit Kat ROM so I many times tried to copy property or carriers folders but nothing worked – each time after a reboot the folder would be empty and I would get looping errors (that the phone app crashed), making the phone borderline unusable. (The phone did read the SIM though).
    Out of rage I tried completely deleting the Carrier folder, and after a reboot – IT WORKED!
    It was unlocked, I was able to use my phone without any errors. Also the boot animation turned into LG and all the Sprint bloat was gone!
    Try this, it might work (don’t forget to delete the telephony file and replace apns file).

  • http://www.droidviews.com/ Rakesh

    Thanks for your time and concern! I would edit the tutorial.

    Regards!

    Hello Rakesh, This is Leonard (matrx10503) from XDA… I will try to write up an amendment for this tutorial.

    For now though here is an overview

    1. You cannot use Total Commander with Kit Kat 4.4.2 (ZVC rom), it will not copy correctly due to not having the right permissions protocol.

    2. This method of sim unlock is the INTERNATIONAL method

    3. You must delete then copy the files to their respective space.

    3a. You must use Root Explorer (or any root file manager, but Root Explorer I know for sure works

    3b. Using Root Explorer: (Delete carrier folder on root, then select Mount R/W, now copy the entire carrier folder to root……Delete apn-config file…and copy……Delete telephony.db, then copy)

    4. To use with GSM US sims…..you must also do a build.prop edit AFTER the INTERNATIONAL method (with an build prop editor like Rom Toolbox Lite):

    ro.carrier=spr
    ro.build.target_operator=spr
    persist.service.crash.enable=1

    ^^Change these settings one at a time, rebooting inbetween^^

    5. After you edit the build prop, you can now restart with the GSM sim…it should be working

    6. If working, there are some caveats!
    6a. You must use a radio switcher to change from cdma/wcdma/gsm etc. and you want to set it as GSM/UMTS
    6b. There is an issue if your contacts do not have the country code in front of the number…either a 1 or a 0
    Tip: download a number fixer from the app market
    6c. Use Tweakker MMS APN app to set you APN settings (For Data to work)

  • Colonel Nicky

    The files disappear once I try to copy them over, even after the progress window shows it being finished.

  • http://www.droidviews.com/ Rakesh

    What problem are you having?

  • Abeliever

    I’m so close. Please turn me onto any material or tutorials to get me through these last steps.

  • Abeliever

    In total commander I dragged and dropped “Properties” into the “carrier” folder on my phone. The progress bars showed that the task was completed but even after many tries. I do not see the files when I open the folder in root browser in my LG G2

  • Anthony Mallette

    I just did all this and I too am having problems with deleting the telephony.db file. I’ve renamed it as well and I’m not sure if I have the ZV7 or 8. Also he is correct with the the property folder not copying anything. Please help

  • Nick Keslar

    Thank you sir! I tried and still it did not work. Also, I am wondering if I have a corrupt download of TC or something. I got it from the link but it seems like everytime I run the program, it does something different. First few times copying properties to carrier, it did nothing, but after several attmpts, it flashed a whole bunch of script that looked like a mini command window across my phone screen. So after that I tried to change pernissions and delete the telephony.db, but the deleted file was still there upon restating. So I restored, and tried again several times, and now it does the same thing again where it looks like the property folder is copying to the carrier folder, but it really is not. Im stumped!

  • Nick Keslar

    I was reading elsewhere that this only works on the ZV7 software. I was on ZV8 while doing it. But also, the thread I was reading had nothing about changing the permissions in the app folder or deleting telephony.db…. Anyhow, so I searched for a ZV7 download and can not find it anywhere. Well this is my go-to site for tutorials anyway so I suppose that I should wait on your reply and hope I can figure it out. I tried everything, was not able to delete telephony.db, it shows up again on every reboot, and my device also says no sim card. But when I switch over to the cm11 rom I have installed, I am getting perfect reception. So hopefully it just is not picking up my sim because it is not unlocked. Thanks and I look forward to hearing from you soon!

  • Nick Keslar

    Any ideas about the guy underneath me? Everytime I delete the telephony.db file from my device, it reappears on reboot. I have busybox and tried several root browser apps. I am using an ls980 on 4.2.2

  • http://www.droidviews.com/ Rakesh
  • dustin

    Still nothing. Is there a way to revert to 4.2

  • http://www.droidviews.com/ Rakesh

    WIt has been tested an Android 4.2.2 but should work on KitKat too. Install Busybox app from the market and then try deleting again.

  • ray

    I did that and press the power button 3 times. i saw the little droid with the blue thing spinning, then It brought me to the configuration menu for setting up the phone to language. when I try to touch the screen it is always selecting the item below the area that i touch

  • http://www.droidviews.com/ Rakesh

    Turn your phone off.
    Press volume down and power button until the LG logo comes on screen
    Let go of both buttons
    Hold the volume down and power buttons again until you see the “hard reset screen”
    Press power once and then power again to confirm.

  • ray

    Thanks, I tried that, but even in the setting up I was not able to select the options as the touch screen was not syncing and was all over the place

  • http://www.droidviews.com/ Rakesh

    Do a hard reset, it’ll be fixed!

  • ray

    HELP Please, I downloaded and ran the following, TWRP and custom recovery. Kitkat 4.4.2 is now installed on my phone.

    I am having the following issues. Can not turn off the phone unless i hold down the power button for several seconds. The touch screen is not responding as it should. I would touch one part of the screen and something else is selected. The touch seems to be off by one row. If I touch anywhere on the screen it would select whatever is below it. It is almost impossible to select the Apps menu as it is non responsive.

  • canerr

    Hello Rakesh. I have been waiting for the twrp for kit kat 4.4.2 to come out since i have installed the d802 rom to my d800 so i could go back to at&t version rom but new twrp is still not available. I see you mentioned that i have to go back to JB. Can you tell me which d802 rom is the right firmware to go back to JB. I think im gonna have to use kdz files to flash the stock jb rom but im not sure which version to use. I am familiar with flashing tot and dll files but not kdz files. Do you think there is a big risk if i try to flash a kdz firmware. Thanks in advance.

  • Christos Kyriakou

    I manage to downgrade to stock 4.2.2 by following this guide: http://www.droidviews.com/how-to-restore-lg-g2-to-stock-firmware/
    The hardest is to set debugging mode on.. took me like 2 hours!!
    From stock 4.2.2 you can easily root tour device and install a custom recovery
    When following the above guide avoid downloading files with chrome.. and make sure you disable your antivirus when executing apps.

  • http://www.droidviews.com/ Rakesh

    Sprint SIM or other SIM?

  • Jairo Santiana

    please help me no read sim card

  • Nick Keslar

    Rakesh, Thanks for all the help thus far and pointing me in the right direction! I do have another question, and hopefully it is my last until I finish this process, but I am finally able to get into total commander, and once clicked into my device, I am not able to find a folder labeled property????

  • Christos Kyriakou

    I also lost my custom recovery… :(

  • Nick Keslar

    ok thank you. should I only download the new link you posted in the comments here? or both that and the original one from the original post?

  • http://www.droidviews.com/ Rakesh

    Delete the old files, redownload the file and try again. I have also added an alternate method.

  • Nick Keslar

    windows could not complete the extraction. destination file could not be created

  • Nick Keslar

    it said some files could not be extracted because there was no access to the directory output

  • Nick Keslar

    yes. but what do I open after I download it?

  • http://www.droidviews.com/ Rakesh

    You are doing it wrong. I just tried it again. Did you download this file?

  • Nick Keslar

    when I get in to click compatability, it doesn’t let me. it again says that the file doesn’t exist :/

  • http://www.droidviews.com/ Rakesh

    Wait, right click the Totalcmd.exe file, click Properties> Compatibility and select Windows XP Service Pack 2 under compatibility mode. Then launch the program as administrator and if it asks, select Run without getting help.

  • http://www.droidviews.com/ Rakesh

    Download the latest version and try on the lower version of Windows: http://forum.xda-developers.com/attachment.php?attachmentid=2654111&d=1395953433

TIA LG G2 D802

  • MMita

    Hi,

    do you mean there is a difference between the version installed by FreeGee and the version you suggest in the first part of the link? Well, the install TWRP with FreeGee was not smooth: first the install was hanged on as it was reported before. Terminated and started Freegee again, launching the TWRP install came back immediately with message: TWRP installed. After that TWRP worked well.

  • Uan

    Actually, the conversion file is meant for converting thee ROM for D802 to D800. Use the device for some time and when TWRP installation is available, flash the ROM for AT&T version. Just wait for some time, I’ll tell you a workaround.

  • http://www.droidviews.com/ Rakesh

    Did you flash the conversion file after flashing the ROM?

  • Canerr

    Hello i have followed all of the steps and succesfully installed the rom everything works perfectly except for one thing. When i try to go back to stock jellybean by using lg flash tool i get an error which says wrong model number. After checking my software status on my phone it says its says d80220a under software information. I have a d800 i assume this is the problem makes flashing fail. Is there anyway to fix this? Thank you so much!

  • http://www.droidviews.com/ Rakesh

    Okay, open TWRP Manager, go to Advanced> Install Recovery and install TWRP from there.

  • Khalil Jaber

    I installed FreeGee as you suggested and inside FreeGee I clicked on TWRP-2.6.3.3 and a window appeared saying ” Performing action TWRP-2.6.3.3″ and it seems to take long time.. cause it is there for about 25 minutes now

  • http://www.droidviews.com/ Rakesh

    TWRP is just app to manage TWRP recovery and using its functions without going to recovery mode.

    You can install TWRP using TWRP manager too but use this instead: https://play.google.com/store/apps/details?id=edu.shell.freegee_free

    Open this app and choose TWRP to install it. After that you can install the KitKat ROM.

  • Khalil Jaber

    how to do that exactly when I already have TWRP manager installed on my device? I download FreeGee from Play Store and Install it? Is TWRP Manager (Root) different than TWRP Recovery? excuse me..

  • http://www.droidviews.com/ Rakesh

    Hmm, it means that your phone does not have TWRP recovery installed on it. Install TWRP using FreeGee app and then try again.

  • Khalil Jaber

    I was at the step right after I copied the room and the supersu to my phone to upgrade it from 4.2.2 (rooted D80210a-EUR-XX) to 4.4.2, I installed TWRP Manager as you suggested and I had to boot the deviceinto TWRP recovery mod to wipe data and cash before I get back to TWRP to install the rom exactly like you explained in the tutorial above.. but whe the device tried to boot the android logo appears with a red triagle on..

  • http://www.droidviews.com/ Rakesh

    Can you tell me at which step or why did you need to reboot into recovery mode?

  • Khalil Jaber

    Hello

    I tried to update my LG G2 to 4.4.2 without losing rot and I guess that I did everything as you suggest till I came to the point where I have to boot my device into TWRP recovery mod to wipe cash and data, but when the device tries to boot the green android logo with a red triangle appears and the device didn’t come any farther, so I had to reboot the device manually.. I tried that many times and had always the same problem. Would you please inform me if anyone else had the same problem? and how to solve it?

    In advance thanks a lot

    Regards

    Boot in CWM, wipe data factory reset, wipe cache partition, go to Advanced, wipe system, go back to main menu and choose install zip from SD card, select ROM, install it. Go back and install Superuser the same way.

    Finally, select reboot system now.

    Hi, how can I flash this with cwm?

  • http://www.droidviews.com/ Rakesh

    You need not go back to stock JB. Just flash it via TWRP/CWM.

    Hi Rakesh,

    Thanks for the tutorial, nice and clear, just one thing to confirm before I will proceed. I am airway rooted and using a custom ROM. Is it possible to move from a jelly bean custom rom to this? Or do I have to be back to stock jelly bean firmware as you appear to be in your screen caps.

So I need the guideline for flashing official firmware 4.4.2. Here I am sharing current firmware details so that you can advice accordingly.

    You can create a copy before deleting but the original files must be replaced with the modded ones.

    I see a yellow triangle on one of the buttons. Have you issues with USB Drivers?

    Press Windows+X, select device manager, right click on LGE AndroidNet USB Serial port COM2, select Properties> Advanced> COM port number and select COM41. Reboot PC and device and try again.

    What are you trying to do actually? Unlock the SIM?

  • carlos

    can u pease help me with that

  • carlos

    im not able to open the tc file

  • sean

    I thought that was the one I had, but I downloaded and installed it anyways, as well as rebooted the PC. Still no luck. Hmm.

    When I try to copy the property folder it goes for about 15% and then the window transfer status thing window just disappears. With the xml file it goes all the way to 100% but I still get an error. Is there another program besides Total Commander that might work?

    I would suggest you to install the stock ROM to get data working again. The ROMs given on this page are not meant for Sprint G2. I’ll update it when the Sprint version is available.

    You can restore the firmware using our guide from here: http://www.droidviews.com/tag/lg-g2/

    Try installing latest driver from here: http://www.droidviews.com/android-usb-drivers-samsung-motorola-sony-lg-zte-htc-asus-huawei-acer/

    Reboot phone and PC and try again.

    Hi,wonderfully written and easy to read and understand. I’ve [as far as I can tell] had success with everything except the last step. I’m currently unable to actually transfer the files to my G2. It’s an LS980. I’ve definitely rooted it, installed the drivers and all that the files just won’t actually transfer while in TC. Any advice? Are maybe the drivers specialized for a certain carrier and I should try to find different ones tailored better to my phone?
