Try to use Autorec, this app will install some partitions. Downloadmode should work. Android 4.4.2 is neaded.

Type first : sudo -s (this is root permissions)

then type : sudo apt-get install dconf-editor

Now plug your phone and follow the guide? At wich android version is the G2? It is rooted with and did you use autorec?

I need help on my LG ls980

First of all i must thank @Shelnutt2 from lg-g2 irc channel who helped me to unbrick my phone and get it back alive. The whole process described bellow came from him.


Description of the problem:

Your LG G2 D802 is living this situation:
1- Rooted and got OTA
2- No Download mode
3- No recovery mode
4- Secure booting error
5- LG detected as qhsusb_bulk in device manager
6- When you boot your device it shows only LG logo with secure booting error, then the screen goes black while your phone is still on.
7- Other symptoms :)


The only solution for you is the following.

I'll explain the solution for an LG G2 D802 10a, then you can apply it for your device model by downloading the appropriate files.
You will need to use linux.
Ubuntu is good enough to make the job. You can use a virtual machine, live cd or a bootable usb stick.

So lets start.

Files to download from here
1- sbl1.img
2- aboot.img
3- rpm.img
4- tz.img
5- openrecovery-twrp-2.6.3.2-g2d802

Thanks to @sabooakhte who has shared his experience:


Now just boot into ubuntu and plug your LG G2 to the computer.

Put the downloaded files in the desktop or wherever you want. You just need to know the path to your files.
unplug any other usb device except your mouse, keyboard and lg g2.
Open terminal in ubuntu then type:

Code:
ls /dev/sd*

It should return something like this:



In this case your device is detected under sdb. you may have it under sdc. just look for the biggest number, in this case /dev/sdb36 so it is sdb.

Linux keeps poping up error message "unable to mount..."? follow this solution by @priority3


now, according to the result of the first command type the following:

Code:
gdisk -l /dev/sdb

you will get result:

Code:

We will be interested by lines marked by red color here. those lines show us the partitions numbers of each file we have downloaded at the begining.
I'm talking about
1- sbl1.img
2- aboot.img
3- rpm.img
4- tz.img
5- openrecovery-twrp-2.6.3.2-g2d802

in our case the sbl1.img is located under sdb2
aboot.img under sdb5
rpm.img under sdb6
tz.img under sdb8
recovery under sdb15

now be careful and try to make it the right way.
we will use dd commands to push img files inside the right partitions.
So lets start:

if youare not logged on as root in ubuntu just open terminal and type
Code:
sudo -i
then type your password

now you must be under root access.

then type the following dd command:

Code:
dd if=[COLOR="Red"]/home/med/Desktop/[/COLOR]sbl1.img of=/dev/sdb2

i put files in the desktop, so the path to the img files for me is /home/med/Desktop/. just replace this path by the appropriate path to your files. one done you will get some information about the file size you pushed and maybe time of the operation.

keep doing the samething for the other files:

Code:
dd if=/home/med/Desktop/aboot.img of=/dev/sdb5

dd if=/home/med/Desktop/rpm.img of=/dev/sdb6

dd if=/home/med/Desktop/tz.img of=/dev/sdb8

dd if=/home/med/Desktop/openrecovery-twrp-2.6.3.2-g2d802 of=/dev/sdb15

Once you finish just reboot your phone, if you did things as described you must boot into twrp recovery.

now just use twrp to flash your ROM and follow this tutorial to reboot into your ROM

only black , or you're getting in fastboot mode?
try to get in to download mode and if you get there with fastboot than use this files
http://downloads.codefi.re/autoprime/LG/LG_G2/LS980/Stock_Firmware
download all from any of "partition" folder and flash them with adb commands via pc

fastboot flash name name.img (or name name.bin) whatever it is
sample : fastboot flash boot boot.img , fastboot flash modem modem.img , ect

then you'll get working download mode and after that you can flash system with .TOT method (or maybe kdz too)

Some different but similar problems occur on my phone

Hi, Mr.Partager.
i'm a D802 user from China, it was really distrubing to me that i got some strange problems after failed flashing Philz Recovery.
Firstly, neither the Recovery mode nor the Android system can I launch normally.It shows only LG logo with secure booting error, then the screen goes black and it lose the response.
Download mode still exists in my phone, but it seem that it doesn't work fine. As you know,during the time when flashing the TOT pack, D802 need a one-time restart to finish the flash flow.But my phone failed to start.It shows only LG logo with secure booting error, then the screen goes black while your phone is still on.And it lose response, again. After a few minutes, the LG FLASH TOOL warn me that it failed to flash.

I've tried many ways to unbrick my phone, including the way you've mentioned in your post, but still failed. When I plug in the phone, the system warned me: error mounting, then unplug the phone automatically.

I discribe my problem in a chinese site: tieba.baidu.com/p/3193405224[/url] but no one's can help me...
can you help me?

Ill give it a try but i cant do anything....

only black , or you're getting in fastboot mode?

Ill give it a try but I can't do anything its just the black screen and that's it nothing else and the download mode don't show up when I do the power button and the volume up and I cant do the recovery cause when I try to put the power button and volume down it don't work the screen is just black nothing else, no fast boot mode no nothing, look this whole thing started when I was flashing the ZVC radios and I think that they weren't my phones radios and flashed them with twrp and when it asked me to reboot I did and when I did the screen stayed black at first I thought that it turned off my phone so when I went to press the power button I saw that the back light turned off and I was like WTF! then I tried to power it on again and I saw the back light turn on but the screen stayed black, then I knew I F-up my kernel cause isn't the radio the kernel? well anyways that's what happened when I flashed the ZVC radio inside the twrp recovery, so yeah I think that what I need is to flash a new radio the radio that I use to have the ZV8 one that I had with my Cyanogenmod but I cant do that cause I cant access my recovery. i need help cause right now i cant use it at all its just with a black screen. :crying::crying::crying::crying:


*EDIT*
I tried everything in that tutorial and nope nothing I changed those things you told me to change and I still have a black screen, I guess there is no fix is there? is there anything else I could try?

Is there any way of flashing a new radio right from the computer? like we did on the other files we pushed in to the device?

For download mode there is no need for power button , just keep pushed vol UP and plug usb

The whole Problem started....


So the whole problem started when I wanted to go to stock LG system I was in Cyanogenmod originally and yes I did have to flash different radios for the Cyanogenmod to get it to work so I flashed the ZV8 radios and I used the Cyanogenmod Rom for like a couple months and then I saw non of the sensors worked like the IR sensor and the others, so after some time I went back and downloaded the ZVC radio and the ZVC LS980 stock Rom for my phone and I decided to try it out and when I flashed the Rom itself it completed successfully and when I started to install the ZVC radios that's when it didn't let me and it told me to reboot and so I did and I went back to the computer and researched about the radios problems and I go back to the phone and noticed that it was off or so it seemed, so I grab it and and push the power button and I notice that in like 5 seconds the back light turns off and then it turned back on then off immediately and I press the power button again and the back light turns on but the screen stays black and if your in a dark room you can see that the screen is on but its only on black screen, so yeah I researched some more and I found out that the radios are kernels and I know that nothing runs with out a scrips or even a kernel so that's what I think I F-UP the (kernel (Radios)) so my question now is there a way to install the LG LS980 ZV8 radios manually? Cause those are the ones that worked perfect when I use to have Cyanogenmod! like manually from the computer like ill have to push the files myself to the right place and **** like that but I am willing to do that if I have to cause I don't want to buy a new phone when I could just fix this one plus I don't have any money for a new phone.. so that's what I did and I hope I could just push some files or some thing back in to place you know. Or am I and my LG totally fu**ed already? :confused::(:crying:

I only changed the Radios from ZV8 to the ZVC and the ZVC Radios F-UP my device, I cant even go to recovery or download mode! I could only push files to the phone through Ubuntu Linux but nun of the files make the device work.

    Ubuntu is good enough to make the job. You can use a virtual machine, live cd or a bootable usb stick.

    So lets start.

    Files to download from here
    VERY IMPORTANT!!!!!!!
    You must use the img files that correspond to the ROM you have installed before getting the problem to avoid breaking your phone. The link above is for 10b_EUR_16G firmware version. So don't use those files if your firmware version was not that one. Instead you should look for img files corresponding to the current version installed in your phone. If you don't know what version you've installed then don't use this method because you will break your phone.
    1- sbl1.img
    2- aboot.img
    3- rpm.img
    4- tz.img
    5- openrecovery-twrp-2.6.3.2-g2d802

    Thanks to @sabooakhte who has shared his experience:
    IMPORTANT: NEVER FLASH ORIGINAL RECOVERY.IMG TO THE RECOVERY PARTITION!!!

    Now just boot into ubuntu and plug your LG G2 to the computer.

    Put the downloaded files in the desktop or wherever you want. You just need to know the path to your files.
    unplug any other usb device except your mouse, keyboard and lg g2.
    Open terminal in ubuntu then type:

    Code:
    ls /dev/sd*

    It should return something like this:

    /dev/sda /dev/sda1 /dev/sda2 /dev/sda5
    /dev/sdb1 /dev/sdb2 /dev/sdb3 /dev/sdb4
    /dev/sdb5 .......... /dev/sdb36

    In this case your device is detected under sdb. you may have it under sdc. just look for the biggest number, in this case /dev/sdb36 so it is sdb.

    Linux keeps poping up error message "unable to mount..."? follow this solution by @priority3
    You can stop the "unable to mount..." error messages from popping up by disabling
    the automount feature of Ubuntu.
    "To enable or disable automount open a terminal and type dconf-editor followed by the [Enter] key.
    Browse to org.gnome.desktop.media-handling."

    now, according to the result of the first command type the following:

    Code:
    gdisk -l /dev/sdb

    you will get result:

    We will be interested by lines marked by red color here. those lines show us the partitions numbers of each file we have downloaded at the begining.
    I'm talking about
    1- sbl1.img
    2- aboot.img
    3- rpm.img
    4- tz.img
    5- openrecovery-twrp-2.6.3.2-g2d802

    in our case the sbl1.img is located under sdb2
    aboot.img under sdb5
    rpm.img under sdb6
    tz.img under sdb8
    recovery under sdb15

    now be careful and try to make it the right way.
    we will use dd commands to push img files inside the right partitions.
    So lets start:

    if youare not logged on as root in ubuntu just open terminal and type
    Code:
    sudo -i
    then type your password

    now you must be under root access.

    then type the following dd command:

    Code:
    dd if=[COLOR="Red"]/home/med/Desktop/[/COLOR]sbl1.img of=/dev/sdb2

    i put files in the desktop, so the path to the img files for me is /home/med/Desktop/. just replace this path by the appropriate path to your files. one done you will get some information about the file size you pushed and maybe time of the operation.

    keep doing the samething for the other files:

    Code:
    dd if=/home/med/Desktop/aboot.img of=/dev/sdb5
    
    dd if=/home/med/Desktop/rpm.img of=/dev/sdb6
    
    dd if=/home/med/Desktop/tz.img of=/dev/sdb8
    
    dd if=/home/med/Desktop/openrecovery-twrp-2.6.3.2-g2d802 of=/dev/sdb15

    Once you finish just reboot your phone, if you did things as described you must boot into twrp recovery.

    now just use twrp to flash your ROM and follow this tutorial to reboot into your ROM

    Hello
    This system only works if you disable automatic mounting of USB.
    But if these Ubuntu 14.04 or higher using the dconf_editor or gconf_editor commands are no longer included, but we can do until dconf_tools.
    The first thing you need to do is to install:

    Code:
    sudo apt-get install dconf-tools
    sudo apt-get install gdisk

    If sudo - l does not work type sudo in front of each command line.
    Take into account that Linux is case sensitive.

    I've created packages with the required bin files:
