It seems like since I cant get my phone to connect to the computer in any way, I can manage to work twrp a bit. But I don't have a rom or sd slot on my damn phone. What if I install a rom on one of these: http://www.meenova.com/st/p/mrg2.html says it is compatible with the g2 but will it recognize it under twrp?
Try a otg cable if you can access twrp
Nevermind you got it congrats

Bricked (??) LG D802 (nordic, 32 gb), what files to use?

Hi guys, my phone was not working well at all so i had to do a factory reset and decided to install the optimus g3 rom. Well, that didnt work and ever since i have been making everything worse.

So i rooted, wiped everything and tried to sideload the rom and it didnt work. Then i installed autorec and lost my knock on ability and could still not sideload using team win recovery (like i wasnt able to mount usb otg); so i changed to CM recovery and i still couldnt adb sideload (same couldnt mount usb otg). So i figured i just flash back to stock with this flash to stock guide but i was not in download mode when i started so that didnt work (and i panicked and didnt take any screenshots of the error messages). I saw my phone and it was stuck in a firmware update screen at 9% and a warning to not remove the usb cable. So i powered it off thinking i could try again from download mode.

But now i just get LG logo with no error message. I cant go into download or recovery mode. Just that logo.

I found this thread, but i notice that the OP has files for a 16GB version. Is it the same for 32 GB north europe? I dont want to make things worse. Where can i get the right files for my system? I browsed the directory but i can't find those image files for 32 gb north europe build.

EDIT#2: So i tried with the files anyways. It didn't work. I used a bootable ubuntu usb stick and when i did the -ls /dev/sd* command i didn't get a long list of possible drives. I guess my phone isnt being recognized at all.

Please help

P.S: sorry about the long post, i needed to vent.

I think I know the way how to get out of this successfully (and avoid bricking, like I did with my device). I just need more experienced devs to confirm that and to provide patched kernel and bootloader so the users can flash them.

The road so far

Bricked my LG G2 LS980, so this is what I have tried and worked so far:

First, if your device is detected as unknown USB device, hold down the power button for about 10 seconds, release and plug it back via USB. You should now see QHUSB_BULK in device manager

ls does not see partitions? Am also stuck there. lsusb does see the device attached. I think what happened was I ran down the battery. The phone is now unable to get into download mode, or any other of the three recovery modes. And it cant charge too. Am looking for a solution to this in other forums and iirc. Hope I will get something soon.

p.s I have read all the 135 pages of comments (*Achievement unlocked: Lurker)

What can I do when this guide made the brick even worse?
I had the QHUSB_BULK before I started with this guide, but now I have literally NOTHING anymore.
No download mode, no recovery, phone only turns on to LG logo.
Volume up + USB only makes it display the LG logo, no download mode.
I can sometimes get into factory reset, but it freezes at processing.
PC doesn't detect the phone in ANY state anymore.
What do I do now?

I am also stuck at this point! (no recovery, no download mode, just the LG logo)

Did anyone come up with a solution yet?

OK, So it took some time but I got Ubuntu to actually install. However after that and a couple command prompts I'm stuck. When I try the command line dd if=/home/sean/Desktop/sbl1.img of=/dev/sdb2. I then get this EXACT error. opening `/home/sean/Desktop/sbl1.img': No such file or directory. Also before that when I try the second command I get this EXACT error. The program 'gdisk' is currently not installed. You can install it by typing:
sudo apt-get install gdisk. From there I get this error. E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

Ok so I don't get any of the messages I mentioned before except the very first one I mentioned.

So how is it that I'm getting these errors?? Once I figured out how to open a terminal I thought it would all go really smooth. But it hasn't.

Random thought. Will the. Img and the 5 files I need that I can download work for my D800 or are those specific to the D802??

    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
    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:

    Code:
    Number  Start (sector)    End (sector)  Size       Code  Name

    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:
    DOWNLOAD
    LG D800 D800_unBrick.tar.gz
    LG D801 D801_unBrick.tar.gz
