Oh, I was hoping to just use the KK installer posted on your forum, or is that not for the D800? My impression was that all of the installers on your forum were for the AT&T version of the G2.

Oops, my bad.. I was thinking Lollipop. Yes, KK works.
[AT&T LG G2] Retep117:
I'll let you know if this fixes anything, I'm starting to think that this phone might be a lost cause, which would be a huge shame. Thanks for the Mega Link downloader by the way, that thing is amazing

Can't believe it, KK fixed it. Thank you so much, your .exe made everything super easy, boot loop and all my other issues are gone.

Now I'm back where I started haha. Do you happen to know how to restore IMEI to a phone? Mine lists it as 'unknown', and I originally got stuck in boot loop trying to fix that issue...

Unable to do anything with Phone

SuperSport -

I have the Lg G2 AT&T model (Black) I had done the Lollipop update to the phone as it was available. Then I started having multiple reboots didn't matter if I was surfing the web on the phone or playing a game or checking email or just talking to someone the phone would shut off in most cases. I came across your post to install Kit Kat back on the phone. I went through the process and it worked although still had a reboot here or there. Unfortunately something happened to where the update for Lollipop was put back on he phone. I just attempted to use the same process to do the downgrade to Kit Kat and it failed on me. When I check the phone it says the following :

Firmware Update

Do not unplug the USB connection until the process is complete and shows an empty bar then under that in the box it shows the following:

User B70

Rooted

Any suggestions would be greatly appriciated as I need to get the phone working due to health reasons.
[AT&T LG G2] crash447:
I would just like to add that using this method to get into download mode is also what I had to do. It is also what salvaged my phone and allowed me to restore it. I was getting to the point where I thought it was a lost cause because I kept getting device unknown errors and such. Once I finally got in download mode from this method, it restored without issue.

[AT&T LG G2] Gotmtdew:
I have tried that even let the phone battery die over night and attempted again this morning. Still the same thing. On the phone the bar is not moving and now it shows in the box at the bottom

User B2

I attempted to continue to try and still not working but on the other hand I unplugged the phone turned it off tried to hold the Volume UP button and plug it back into the USB Cable. All of A sudden I am getting asked by Windows to Format a new drive checking I have a bunch of drives listed but not able to do anything with them.

Rooted
[AT&T LG G2] SuperSport:
DO NOT FORMAT!

Have you flashed other model Firmware or ROM's to your phone? I'm not positive, but I believe that's what causes this issue. Be very careful at this point. You need to follow this thread to try to get it back: http://xdaforums.com/showthread.php?t=2582142

Note that they are showing the repair for a D802. You must get the correct files for a D800. If done wrong, you will be bricked permanently, or until you can get to a JTAG. I've never done the process myself, so ask further questions in that thread so you get the correct answers.

Good luck, and let me know how it goes.
[AT&T LG G2] Gotmtdew:
Windows will not let you format the drive that showed up anyways it says its Write Protected. I tried to turn it off and back on again and now it just goes back to the Firmware Update screen with User B0 and Rooted.

I have never done any other Custom Roms have not wanted to explore with any honestly. I used the phone the way it was and then when the update for Lollipop happened that is when the phone just wanted to shut down no matter what I was doing.
[AT&T LG G2] SuperSport:
Any chance it's still under warranty? Being that it died during an update, they would likely cover it.
[AT&T LG G2] Gotmtdew:
I wish no warranty. I am not due for an upgrade until November of this year. I have already spoke with them and they don't care to do anything about it. They only wanted me to look at their Next Program. Which I am not one to upgrade my phone every year I keep the phone that I get for my 2 year contract.
[AT&T LG G2] SuperSport:
So, your phone is rooted? Do you have TWRP installed and you got an OTA when it was rooted? Maybe you need THIS FIX instead...

Go into twrp, Go to advanced, Go to terminal, Click the arrow,in bottom right.
Enter
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
Hit enter then enter this dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
Hit enter and reboot

If all else fails, I think I'd argue with them a little more. I believe when their update causes your phone to die, it might be a good case for a replacement.
[AT&T LG G2] Gotmtdew:
Phone was not rooted never cared to mess with it like really. I did go back to Kit Kat after the Lollipop update had caused multiple reboots/crashes. Then mistakenly the Lollipop update was put back on. Which is now how I am at this point I attempted to go through the same process as I did the first time (from your First Post) and it failed during the process and now I am where im at with it (not moving from the Firmware Update Screen). I have attempted to talk to multiple people within AT&T and they only want to refer me to getting into their "NEXT Program".

[AT&T LG G2] SuperSport:
I don't know where to find the TOT file, but you can get the LolliPop KDZ file from [MENTION=2607037]hyelton[/MENTION] 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://xdaforums.com/showthread.php?t=2432476

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.

Sir supersport....i have watched your videos on youtube. They are really good and precise. The problem is I have lg g2 d800 att model and i have root acess and twrp recovery installed and the custom rom also, grola rom v1.2 it is lollipop 5.0.1.

I have the d800 on stock Lollipop OTA rooted with twrp. Can I also use this to go back to KitKat? Thanks for the help.
[AT&T LG G2] SuperSport:
My understanding is that if you first flash a Custom ROM or Stock ROM that is based off the Stock Firmware, then do this process, you will have success. I have not tried this because I've never Cross Flashed myself, but I think that's what I've heard works.

Thanks SuperSport. I was able to restore to 80010o. Super easy per your instructions and files. Was having issues rooting with ioroot22, but worked after downloading ioroot23 per your suggestion.

ATT rep mentioned I was her second person to request this and they were able to work out all the kinks to give a quick release. She also mentioned they worked on the Samsung's 4.4 update before the LG's. Not sure how reliable her words were.

Not yet. I'm looking into whether or not I can build installers for the other versions. I don't have other phones to test on, so I'm a little hesitant to do it. With ATT version, I can run through it myself before releasing, so I KNOW it works.

Oh, it is EASY compared to finding, downloading, installing, and running all the files the manual way. It's not easy compared to making a sandwich. ;) Unless it's THIS Sandwich, then it's much easier than that!

For anyone looking to do this, there is now an easier method to get KitKat on your phone and KEEP Root. See AndroidUser00110001's thread here: http://xdaforums.com/showthread.php?t=2665391

The difference between these methods is that you can use his method just like flashing any other Custom ROM using Custom Recovery like TWRP or CWM. Only difference is that you are flashing the Stock OEM KitKat ROM.

When you use my method here, your phone is WIPED. When you use his method, you would wipe like you normally do when flashing a Custom ROM, but you don't have to wipe the Storage Card space, so your data will remain intact. (Of course, ALWAYS backup before modifying your phone, just in case)

If you are going to return your phone back to warranty, I would suggest my 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.

If you already have a Custom Recovery on your phone and want KitKat quick and easy, use his method. ;)
[AT&T LG G2] IcOpRo:
Quick question, on sorry for noob question btw, I currently have recovery, If i want to flash any of the KK options, can i just use one of your JB options to get recovery and root back?

[AT&T LG G2] SuperSport:
That is correct. If you use version 10o, you need to use ioroot23. Some people report ioroot22 does not work. Or, you can use version 10d without issues.

Device Model Mismatch error

If you are getting the Device Error Mismatch error due to having flashed a ROM to your device that was not for the D800, you can try the DLL file listed at the bottom of my first post. It will bypass the Device check. But, obviously, be careful with this dll file as it will allow flashing the wrong Firmware to your device. Be sure you are flashing the Correct Firmware for YOUR device!
[AT&T LG G2] nabril15:
i followed these easy steps this morning (lg tool to 10o, ioroot23, OTA's-k and c), and it worked beautifully. Thanks a lot.

Is the installation of SU needed? I installed it from google play, but when I run it, I get an error message:

There is no SU binary installed and SU cannot install it. If you upgraded to 4.3, you need to manually re-root.

I downloaded ES file manager and I tried to enable Root manager, but it told me I could not do it.
[AT&T LG G2] SuperSport:
Unfortunately, as mentioned in the First Post, you cannot ROOT KK at this point. Dev's are working on it. You can only install JellyBean, ROOT that, and then update to KitKat to keep ROOT. In the First Post, I've got a link to another thread where you can flash KK and SU to keep Root in KK. Please check back to first post. That method requires you to be ROOTED, and have a Custom Recovery installed. SO, to do that, you will need to Flash back to Stock JB, root it, then update.
[AT&T LG G2] nabril15:
Supersport..thanks

my apologies. I read, and re-read, and re-read. I misunderstood what the true meaning of "get KK and keep root means". Following the steps I followed, I kept root, but not with the full root functionality (based on your reply above).

So, using the other link, will get us rooted KK with full root+su functionality ? I assumed that using your method would yield that - full root and su functionality.

thanks again.
[AT&T LG G2] SuperSport:
MY MISTAKE!!! I'm so sorry... I read your last post wrong. I'm tired today, and was not paying good attention.

Using this method, you SHOULD have Root and SU. I've done it a few times. I'm not sure why it's not enabled on your device.

Each time I've done it, I did verify Root in 10o using Root Checker before updating, but I cannot imagine why that would be necessary, but maybe???

To answer your last question. Yes, flashing the ROM on AndroidUser00110001's thread using TWRP does keep full root too. You'd need to go back to 10d or 10o, Root, add TWRP (I use FreeGee from app store, so easy a baby can use it), then flash AndroidUser00110001's ROM using TWRP. Follow his instructions carefully. You flash the ROM, then BEFORE rebooting, flash SU, then reboot.

First off, keep in mind that you might not be able to downgrade back to KitKat after updating to Lollipop. I've heard reports that you cannot flash back due to driver or baseband issues.

With that said, follow the instructions here to update to Lollipop:

You are correct. If you combine the easy instructions from that thread and the files from THIS THREAD, you can get there.
[AT&T LG G2] priuslover:
My G2 isn't being shown in COM ports in my device manager.
[AT&T LG G2] SuperSport:
When you unplug and re-plug your phone, does Windows see ANY new device? Maybe the drivers are not being installed correctly and there is a generic device being shown?

If not, then try another cable, or another USB port and see if that helps. If no luck, try plugging into another PC and see if anything happens. If you get something on the other PC, then you will need to diagnose your PC to continue. If nothing happens, then you might have a bad USB port on your phone.

Try connecting when in normal Powered On mode, and also when in Recovery Mode. See if either mode does anything.

Just got a unlocked AT&T LG G2 and I want to root it.I`m on 4.2.2 (D80020U).If I need warranty and need to go back to stock the stock firmware,the firmware provided isn`t the same as the one I got (D80020U) my phone came with.

So I`m thinking that reflash back to stock with firmware version (D80020C) and then update to version (D80020U).Is this correct?

That is correct. For warranty purposes, you don't have to worry about the firmware Version you have on the phone, only that the firmware is Official Firmware.
