D802 Bricked after LineageOS 14.1 installation - G2 Q&A, Help & Troubleshooting

Hello,
after successfully rooting my G2 and installing TWRP I wanted to get LineageOS 14.1 on my phone. I installed the 14.1-20170410 build and the gapps mini package through TWRP, but after rebooting my phone it won't get beyond the lineageOS loading animation, even after a few hours. So I restarted it, but it still gets stuck. Now I can't access recovery or download mode trough the hardware buttons, it just doesn't do anything, when I try to get into the download mode it just shows the charging screen. The only thing I could get to so far with the hardware Buttons is the hardware key control mode, but I don't see anything useful there. My PC only recognizes the phone as a HID device and I can't do anything with ADB or the LG Flash Tool. I've found guides which deal with a hard brick, but in these guides the phone should be recognized as qhsusb_bulk in the device manager which isn't the case with my phone. Does someone have an idea?
Thank you,
Wambomeister.

What I would do:
Boot via Buttons into TWRP, perform a wipe, flash Lineage + Gapps, wipe again, boot into system.
Good Luck!

Thanks for the answer! But don't all solutions mentioned in the thread you posted require either access to the download or recovery mode?

Hello,
It is pretty impossible to brick LG G2. I have this device already for 3 years. Just contact me per email.

I can only help you through Remote Control: TeamViewer.

I got the same problem when trying to root my G2 (D805). It never gets to download mode. Just shows the LG logo with the message "Secure Booting Error Cause : boot certification verify". Are you guys able to help me?

Dear Jairo,
Sorry for the late response. I am not sure what is difference between G2 (D802) and (D805) on the software side. Yes, I can try to help you. As I said, it is pretty hard to help somebody without remote control, because firstly, we need to diagnose the situation.
Okay, let's move on.
You will need a computer, USB and of course your LG G2 (D805) bricked device.
Download LG drivers and install it on your computer.
URL: www102.zippyshare.com/v/fBp5aQhM/file.html
Connect your LG G2 device per USB to the computer.
Now press and hold: Power button + Volume Up button (at the same time), until your phone reboots. After force reboot, you should be in Download Mode. If you failed, try again.
If this does not work, let me know. Sorry for the bad English. I hope you understand me.

Can't unbrick Optimus l5

Hello, I ran into a problematic brick on my L5...nothing seems to work to unbrick it.
I followed the guides step by step using the KDZ updater and the appropriate firmware for my country, but it doesn't work.
How I bricked it:
I had CM10 installed and perfectly running for a month, so today I decided to attempt an overclock to speed the device up a bit.
So, I downloaded and installed the modded kernel, flashed it using CWM and rebooted the device. After that, the device just keep booting up, showing the LG logo and then a black screen.
Now, after trying to flash the old firmware after going into download mode it just stops on the LG logo with the flare (sun ray effect) spinning around the logo all the time...It's been like that for almost 30 minutes now. I attempted re-flashing it 3 times but nothing seems to work.
What do I do?
Thank you in advance.
It's bootloop. When I had L5 I had the same problem after flashing bricked phone via KDZ.
Do hard reset with key combination. It worked for me. Phone will boot up few minutes.

This is what I get when I connect the phone by USB.
I just cant get into emergency, DIAG or emergency CS
KDZ the phone connects and then I get a message afterwards PHONE NOT FOUND.
everytime I install the drivers by LG support tool, it keeps giving me the option to install the driver, like I havent done it a hundred times over.
I think there should be a driver somewhere that can be installed but the only people that have this driver are LG tech's. So they can bill you after
send the phone in cause you rooted it. So the one billion dollar question is witch hero will find a way to unbrick this device. We only need a way
to get a driver to install and we are home free. Or maybe the only other option is throwing the phone for sale on internet for spare parts
HELP PLEASE HELP find a way to unbrick this phone. Believe me I flashed and bricked alot of different phones and there was a way out but in
with this phone it seems impossible!!
And there is no mode to put it in in because te volume buttons don't do crap, the home button also, the only time that the phone does show up is when windows tells me it has an unknown device that I for the love of god can't find a driver for. I tried SDK, the LG drivers, but no dice
Did you try emergency mode? (volume up + volume down + power button)
If not, see if you can enter it and then flashing your stock firmware with Software update [KDZ] 1.0.4.4 (KDZ-Flasher).

I no longer use this device, so I'm not aware if other users had the same issue like you.
First, did you try searching this forum for similar issues?
If not, it might be a better good place to start.
Second, please explain better whats happening to your phone:
Can you turn it on? If you can, what do you see?
Can you enter recovery mode? (volume down + home + power)
Can you enter emergency mode? (volume up + volume down + power)
Did you try flashing stock firmware with KDZ-flasher?
What ROM did you try to install? Did you check the ROM's page in these forum?

It's very problematic that you can't enter your device into emergency mode.
I think the only option that is left regarding software is to uninstall all of the drivers that are already installed for you device,
installing the latest drivers from the official site, and then try to use LG Mobile Support Tool to flash stock firmware.
Other than that you can only send it for a hardware repair

Hey,
When i say download mode i mean (Remove Back Cover and Battery>Plug in USB while pressing Volume Down Key!)
As far as i guess we can enter emergency mod by pressing both the volume keys and power key at the same time.
I tried using KDZ but at some point gives me an error of WParam and LParam as I posted above.

Yes, you're right - to enter emergency mode hold volume up + volume down + power
When you're inside you'll see on your screen "EMERGENCY MODE" on a yellow background.
Only the use KDZ-flasher or the lg mobile support tool.
If you're indeed in this mode, then try what @kien_vip suggested above.

Before entering emergency mode you should remove the battery for a few seconds. Place it back into your phone then enter into emergency mode. Hope this could help you.
Lg update tool uses baseband as the only check whether your device has the latest update. This means you will get the update if you use an older baseband. However, you should try emergency option.

[Q] Hard Brick D800 - Please Help! At a loss

Any help is appreciated! First some background:
Flashed device to stock using KK 4.4 version d80020c following steps found here http://forum.xda-developers.com/showthread.php?t=2432476. Successfully rooted using directions (and ioroot25) found here https://www.youtube.com/watch?v=HKuedInhdjU&noredirect=1.
Here's where I got into trouble...Downloaded TWRP 2.7 recovery img and flashed via Flashify. Since this step, my D800 has the exact same symptoms found on this thread http://forum.xda-developers.com/showthread.php?t=2582142.
- No download mode (tried many times)
- No recovery (tried many times also)
- Secure booting error
- LG detected as qhsusb_bulk in device manager
- Device is recognized as 15 different drives, one of which contains a folder named image with 79 different files being .B0X files and Microsoft Access Add-in Data files
- Upon restarting, LG logo with secure booting error, then the screen goes black while your phone is still on
I've followed the steps in the thread that matches my G2's symptoms, run ubuntu 13.1 in VM, apply usb filters for my device which is then recognized as either LG Electonics Inc. QHUSB_BULK or Unknown Device 05C6:9006 when running in VM.
Upon running command ls /dev/sd* in VM Ubuntu Terminal, all that is returned is /dev/sda /dev/sda1 /dev/sda2 /dev/sda5 which are the partitions for Ubuntu, no LG.
I've tried to download and update the Qualcomm drivers, device manager tells me that the drivers were recognized, but cannot be installed and do not pass the hash check (Note: PC is running Windows 8.1).
I've spent over 12 hours on this trying to fix this problem, researched and searched everywhere. If I could get ubuntu to recognize the device, I would be able to continue on with the instructions on this thread http://forum.xda-developers.com/showthread.php?t=2582142.
Links for windows 8 qualcomm drivers, suggestions on how to get the device recognized in ubuntu vm, experiences from others in similar situation, or any with experience working with LG to get a repair done if I'm SOL (as in eMMC is fried) would be so helpful right now.
Thank you all!
After flashing recovery did you flash a patched kernel to boot stock kk?
Sent from my LG-D800 using Tapatalk
I had the same, also with a lot of drives etc.
Screen is black but low backlighted?
Then try with pluged USB Cabel in Phone, hold Power button until screen is realy off, then hold the Power Up Button and plug Cabel into PC.
So I got download mode after I tryed many times
I had problems a few weeks ago getting mine to go into Download mode... turned out that the cable I was using was great for charging, but sucked for everything else. Once I switched to a different cable things worked fine and I was able to load D80010c on the device.
I was running D80020c this morning (with the D80010c boot.img to have a custom recovery) and decided to do an update. Since you can't load D80020k if you have the older bootloader I went all the way back to D80010c, updated to D80010o, D80010q, D80020c and finally D80020k. I was able to root that using IOroot and have restored everything back onto my phone.
-Daryel
Thanks so much for the responses! I've tried endlessly to get the device into download mode, and tried a new cable to no avail. Any other suggestions?
The URL you've linked to will help you solve your problem.
So once you power off your device, hold volume down and power till the lg logo shows, then release shortly and hold them again together till the white window with "factory reset appears", you should notice a text behind the white screen it's fine. So right now when you think it's gonna enter recovery mode the screen is gray(not black), now you connect your device to your ubuntu or whichever linux. You will notice the screen repeatelly blinking when linux is trying to automount the partitions. Figure out which device it is according to the messages it throws. (sdc, sdb, sdX)
This way you should proceed according to the instructions on the thread you linked.
d800 partitions are here
Still no luck

Thanks for your advice.
I got the white screen asking whether or not I want to perform a factory reset. If I choose No, the phone sends me right to the LG Logo with the error screen. If I choose Yes, it does the same thing. If I plug my phone into my computer while on the white screen asking if I want to perform a factory reset, the device isn't recognized and the PC doesn't see it as plugged in or mounted. I'm not sure what you mean by the timing of when I should try to plug in my device. Thanks again for all your help.

As soon as in the background of the white menu (factory reset) the secure boot appear plug it in. I'm not sure how much usb filter helps you(maybe it does) but try installing ubuntu over WUBI installer so your win remains. Or at least try ubuntu from usb stick. So you can know for sure if it's working.
Hi Sneaky E. I have the same issue you have. I'll be following your thread. If I figure anything out I'll let you know. I am also having an issue getting mine to charge now. Have you tried downgrading your TWRP?

I've tried all USB ports, 2.0 and 3.0. I feel like if I can get past this there should be no reason linux can't see the partitions in the phone. Please Help!!!
Ok so thank you for your help so far. I was able to install Linux on a USB drive and ran the commands and pushed appropriate files from there. I pushed all files including recover.img but the phone will not boot into recovery. Please help!
Thank you!

you are not alone dude. i had the same issue since sunday and i have spent almost 46 hours already trying to restore my LG G2 F320S korean model.
i followed that instruction in linux, everything went well but then I ended up with a phone not going past the LG logo. the screen no longer dims like how it used to with the secure boot fail error. again, it stucked at the LG logo and thats it.
pressing the 3 buttons though for 5 seconds shows a white screen with 3 options and a bar code under.
but all of these options will just take me back to the LG logo.
I went to a phone technician today, and they said the doing a JTAG fix is the only way to resolve the problem because after trying to fix it with linux, it is no longer identified by my PC.
what are your solutions so far?
anyways before this issue came up, i tried to flash TWRP using flashify, it failed. then went back up. tried to update the OS via OTA then thats it.
i home someone could help us out.

Mode download doesn't work

Hello,
I want upgrade my LG G2 with a new rom 5.xX
This phone have only the operator update. No custom, no trwp, nothing...
I installed drivers and when i want access to download mode. I can't. I use the good proccess with vol up then plug usb cable always with vol up presses.
follow this procces after a little moment my phone show me battery logo charging.
So i can't access to download mode.
I would use this process
t was NOT bricked. I finally tried playing around with the LG Mobile Support Tool (B2CAppSetup.exe). Of course it detected that my phone already had the latest firmware from T-Mobile, but then I clicked Options>Upgrade Recovery.
It downloaded for a while then I noticed it had put my phone into download mode (it said "Rooted" in red letters at the bottom). Then it flashed the same firmware over and I immediately tested, it entered download mode right away. But I didn't end up needing that as Stumproot was able to brute force it now after the recovery flash.
Anyway, I couldn't find an answer anywhere else. Most results also have a bricked phone, but that wasn't my issue. This solved my problem and maybe it could work for others.
but it's impossible for me to install B2appsetup on my pc the installation begin then stop after 5s then nothing.
I have Win 10.
Do you have a solution for me , please??

Hello my friends.
I installed CloudyG2 3.3 to my LG G2. And on this morning, my phone closed. I tried to open but, i can't. The screen stayed at LG logo screen. So i tried to do Hard Reset with buttons. I said Yes-Yes but there was something wrong.. A mistake. (boot certification error) I can't enter TWRP screen.
I tried to install stock rom with Flash Tool. But i can't.. Again.. Because it stuck at %2..
So i can't install stock rom and i can't open my phone. Can anybody help me?
Sorry my bad English.

First of all power of your phone by long pressing power button until screen light goes off completely
Then keep pressing volume + button and connect it to PC via USB cable. [DOWNLOAD MODE]
Now you must be in download mode, simply flash stock firmware.
If you can't enter download mode then you might be in fastboot mode.
here are some threads..find out which one is related to your problem follow instructions carefully.

Thank you my friend for all your answers. In substance;
I can't open my phone. (Staying at LG logo screen.)
I can't do "Hard Reset" with phone buttons. (Because of "boot certification error" screen.)
I can enter "Download Mode" but I can't loading any .KDZ file with Flash Tool. (Stuck at %2)
My computer can't see my phone when I plug that.
Very hard situation. :crying:

Reinstall LG drivers and PDA
then connect phone with PC in download mode.
open device manager and search for 'COM ports' list if you see your device there then you are ready to go.
If your device is not there then search under 'Other devices' and manually install drivers.
If you can boot into download mode and still you can't see your device in your PC then it's not problem with your G2. It's your PC which is causing it all.
Try another PC.
