Anyone ever figure out why it gets stuck on 49%?
[G2 General] cosine83:
FYI, for the T-Mobile variant, it's hold volume up and plug in the microUSB cable to get into download mode.
[G2 General] mandroid717:
just a question. i used the Software Update tool to flash the KDZ file on my optimus G. do you think i can use the same tool to flash the KDZ on the G2?

I flashed D802 EUR firmware but the flashing finished on the phone first before finishing on pc is it normal?

When its finished on your phone that means its done..... If you noticed on the computer it counts down for rebooting.

Turn off your phone,and while pressing volume up connect the usb.
[G2 General] 1iam5mith:
So this will void the warranty?

What advantages would I get from doing this, over staying with what is already on mine? The carrier I bought from only adds a splash screen and removes voice mate, doesn't add anything of their own to the device... so what benefits would I get from doing this?

Thanks :)

accelerometer error.

hi, i installed F240L20c KitKat ROM (Korean) to my LG Optimus G Pro E980 (AT&T). all works perfectly, but have one problem. Accelerometer isn't functionally. when i rotate my phone to right, then screen flips to the left. then from this cause camera is bad. please help mee!! :crying: what can i do?? how can i calibrate the accelerometer?? :(

sorry for my english :)
[G2 General] hyelton:
E980? Your in the wrong thread. And.your not supposed to flash the Korean firmware on that phone that's why
[G2 General] yoitsjustin:
Hi, about six seconds in on my T-Mobile LG G2 I am getting something saying my phone is disconnected. My phone doesn't have a recovery or an actual system. So I'm stuck on a turned on black screen. If I power it on or try to enter recovery mode I get "secure booting error" and there is no way to reset it. I can enter download mode but it still says it's disconnected. I have tried other chargers and the computer is picking up the phone
[G2 General] Ramil Rahib:
yes, e980. but i want kitkat. then, i installed this rom. problem is only accelerometer issue. all works ok. no an idea for this? how calibrate accelerometer
[G2 General] hyelton:
Installed a G2 rom??!! That's risking of breaking your device! There's not kitkat.for the e980 so I'm shocked your phone is even working at all. And no there's no fix as it's not even supposed to work.
[G2 General] Ramil Rahib:
no my friend, its LG Optimus G Pro Korean versions rom. F240L20c. yeah, its risk, but no other problems over accelerometer.

Reverting back to 4.2.2 stock failed.

I went through method 1 without any problems and it seemed to all go okay until i got stuck in a bootloop. I live in New Zealand and bought the phone through a parallel importer. In the official lg pc software it says my device is recognized as DD80210B, Was I correct in trying to flash the D80210A_00.kdz open European file when coming from stock 4.4.2 to 4.2.2? if not could someone please direct me to the correct file i should be using?

Thanks in advance

Edit 1

Found D8210B_00 under Asia & SEA, Im guessing i shouldve flashed that one?

now i just have to wait for it to download with new Zealand data speeds :silly:
[G2 General] rodpgfx:
Guys! I don't know what just happened, but because I couldn't figure out the process for returning to stock on my LG G2 using the OFFLINE folders in the original post, I decided to try the legit way through LG.

I am using the Bell (D803) variant of the LG G2 and the upgrade worked legitimately! My phone is upgrading all my apps through the stock firmware as I am typing this......

Now I can flash the LG kitkat upgrade :) :) :)
[G2 General] sarvan_me:
Hi,

Yesterday I got the same problem when I was trying to downgrade from KitKat to Jellybean. Please follow the below step

1. Unzip the file LGMOBILEAX.zip

2. Go to C:\ProgramData\LGMOBILEAX and delete all the files inside this folder.

3. Copy the contents from the unziped LGMOBILEAX folder and paste it inside C:\ProgramData\LGMOBILEAX .

Done. It should work now.....

---------- Post added at 10:29 AM ---------- Previous post was at 10:22 AM ----------

I had the same problem yesterday when I was trying to go back to stock from 4.4.2 to 4.2.2. It keeps rebooting with LG logo and nothing happened. As suggested by this thread owner I did the HARD factory reset. Please find youtube video how to do it ( By pressing volume down + power button etc.....) . Boom !!!!! It loaded and I am currently in 4.2.2. :) Everything worked fine.

Please Note: I am not quiet sure if you have loaded the correct kdz but just try a hard factory reset and check out once. It worked for me and I am from India.
[G2 General] themayneman:

[G2 General] maddog497:
I've read and re-read this thing. Thanks for adding the Telus KItkat firmware (as well as others).

I am rooted on 4.2.2. If I use this method and return to stock firmware, I will end up on 4.2.2, but not rooted and can take the official update?

If I use this method but use the kitkat firmware instead, I will be on the official kitkat firmware, but not rooted and can take any further updates?

If this is correct, I might as well go for the kitkat?

Thanks again.

[G2 General] mesebar2:
i mean that if instead of clicking "Normal Web Upgrade" and then "Upgrade Start", i click "Start Update", i get "extract file error" (i know the guide does not mention doing anything like this, i simply tryed for i was frustrated trying and ending up in the LG Mobile Support Tool telling me that i already have the latest software available)

EDIT: I DID IT!!!

i had to use the SECOND method!

i uninstalled everything and then installed it again, at that point i manually changed the hosts file and then started the "automatic offline procedure", enabled windows enabler and did the steps as described: at that point i finally got the window asking me for COUNTRY and LANGUAGE

try editing the hosts manually :)

For D802 the first method will work properly,if u give administrator rights to Automatic Offline Procedure.vbs.

The simplest method is "

After step 5, run command prompt with admin rights"

ie- search for cmd in start menu -> right click on cmd.exe and select run as administrator. it will open comand prompt with admin rights.

from cmd locate LG_KDZ_FW-Update_OfflineFix folder and run Automatic Offline Procedure.vbs it will open R&D test tool with out any error.then follow from method 1 second step..

downgrade to 4.2.2 via kdz method then dont root it and check in download mode it will show unrooted. if yes then apply via ota 4.4.2

There is no OTA yet, that's why i upgraded it via mobile tool, for me it's same, i'm dissapointed they didnt enable immersive mode..

So it's ok if i downgrade via kdz offline method and then via online orignal method in lg mobile tool to 4.4.2?

yup but kitkat dont have root yet so i suggest stay with 4.2.2 only i am also with 4.2.2 root

Stuck in an install loop

I am stuck in an installation loop that started while updating to KitKat.

I was happy with my LG G2 (T-mobile, D801G), but wanted to use root apps. So, I rooted and installed TWRP, but did not flash a custom rom.

Tuesday when I woke up there was a message saying I could download KitKat. After installing my last system update I lost root, so just had to unroot and re-root – took me about 15 minutes. So, I decided to go ahead and install KitKat.

It downloaded and began to install, but got stuck in a loop. The LG logo flashes for 5 seconds, the little droid pops up with his stomach spinning and the message “Installing system updates” but shows for only about ½-second. Then the screen goes black for 2 seconds and it starts again.

I can get it into the factory reset screen, but when I say yes-yes, it puts up the message :

Error: Boot certification verify

341120

341170

341220	Secure booting error!

341270	Cause: boot certification verify

341320

341370

(the numbers are different each time, but always 6 numbers in increments of 50)

Then it sits in a black, but not quite off screen until I hold down the power button to turn it off. When I turn it back on, it shows the logo, then the droid showing the message ‘Erasing…’ for a full second, then switches to the ½-second ‘installing system updates’ loop.

It will go into download mode (where of course it says ROOTED so I can't use my warranty).

I tried this: http://xdaforums.com/show....php?t=2582142 but I couldn’t get Ubuntu 12.04 to install gdisk. Then I noticed that

ls /dev/sd*

returned the same values whether my phone was plugged in in download mode or unplugged completely. The values were

/dev/sda, /dev/sda1, /dev/sda2, /dev/sda3, /dev/sda4.

I tried the next step anyway

gdisk -l /dev/sdb

and got the error saying gdisk was not found, but I could install it with… etc. I tried to install it, but it wouldn’t work.

I tried both methods from this thread, and the R&D Tools just says 'Your device has the latest software available from the LG Mobile support tool'.
