[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?

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.

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?

VirtualBox Error
VirtualBox recognizes the device is plugged in, but won't allow me to push the device for use in linux. I keep getting this error message:

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.

[Q] [HELP] LG G2 D802 in coma - Really Deep, Hard and Seriously Bricked

A few posters here claim that the G2 is unbrickable - but I think I can challenge that. It started off with me wrongly flashing the Cloudy ROM 3.0 - what I didn't realise only till later was that it was intended for the Korean variant of the G2. Dummy move indeed.. I had previously taken the necessary precautions and took a full titanium backup and ROM backup onto a USB drive via TWRP - I previously ran Cloudy ROM 2.2 with Dorimanx Kernel on KK 4.4.2.
Right now, the phone doesn't seem to power on via buttons. When I plug it to the PC via the USB, I get "QHSUSB_BULK" as an unknown device only.. no black screen while on, no drives or COM port.
First off I want to be clear that I know I and only I am responsible for bricking my phone - The reason I'm in this mess is completely down to my stupidity, and trusting 'educated guesses' instead of confirming specs black of white. Just wanted to be clear in case anyone gets the wrong impression.
So this is more or less the sequence of events;
1. After flashing, I got stuck in fastboot mode.. (can't find the link) I followed one post where I needed to flashed .img files via the Fastboot CLI (similar to ADB). I used the images from the LG G2 D802 16GB in europe. source.. It was a toss up between the EUR and non EUR, and so I made the first of my so called 'educated guesses' that sent this phone deeper into the ground.
2. Something went wrong as when I rebooted the phone (had no idea what had gone wrong at the time), I got no logo. After some time, I noticed the screen on with a black background. when plugged into the pc, the QHSUSB_BULK would appear and with it a bunch of drives that Windows thought needed repairing. so I followed This .. I installed ubuntu, booted to terminal so I don't get those auto discovery pop ups, I used the images recommended there for my device (again, it seemed to make sense to use the same that the OP was using for my LG G2 D802 16GB in europe... After I rebooted, it was to my horror that the screen didn't even turn on, with no drives being detected via USB.. just the QHSUSB_BULK. This is what made me realise that the culprit was most probably using wrong images rather than improperly executing the instructions.
3. I opened the phone and tried shorting some capacitors where I'm supposed to see the drives again to no avail. I even tried shorting the capacitors ends as described here to no avail. I done a good full hour shorting the hell out of those capacitors (the post says to keep at it till it works cos it can sometimes be a bit tricky) but I saw no change. I would like to try the DL mode described there but I can't figure out what I have to ground from the images shown in the post regarding the "BOOT CONFIG".
This is basically the state the phone is in at the moment. so to recap:
No bootloader,
no recovery,
no fastboot,
no download mode,
no drives when in QHSUSB_BULK mode,
no COM port.
From the multitude of unbricking guides here, I gather that I either need to see that bunch of drives again when via USB or a COM port. I tried installing Qualcomm drivers, thinking that if the pc recognises the device, I might get the pc to identify the COM port, but the driver couldn't be installed for the QHSUSB_BULK device (got some error.. I can update this post later).
I tagged this post as a question.. i'm sure there's a question here somewhere...

When I first tried to enter QHUSB_BULK mode on mine, I took ages. Seriously, ages. It kept not showing the drives. Important thing to remember, in my opinion, is to use Linux (latest Ubuntu in my case). If you keep trying, eventually they will pop up for a split second. I can't remember how I did it, but you have to use a partition tool, I think, to get it to freeze the positions of the drives. Then, once it's 'mounted' them, you can try (and keep trying) to flash to each partition.
Mine was well and truly screwed, so I flashed a blank partition table on, then flashed each image onto that. It took a lot of trial and error, though, because it kept not showing the drives.

Mine was exactly the same I also had a blank partition table.. Anyway just keep trying because It took me a while to get mine working.. I was trying to short the capacitors but it seems to be quite hard sometimes especially if you aren't carefull.. Because you can start to mess with the soldering of the capacitors and it'll be harder after that.. It happened to me..
Anyway here's something I've wanted to ask everyone, after I sucessfully put my phone back to life, it seems like the middle button isn't working, the LED and the volume rockers are fully working, but if I ever press the power button after some time it shutdowns just like if I pressed and hold for a while, has anyone got this problem? It seems like the flex cable or something is damaged but i wanted to be sure it's really damaged or just something I could solve.. thanks and sorry for the off topic..

Bootloop with logo, no recovery, do download mode, not recognized only charge

So a little backstory first. LG G2 D802 with CM13, flickering screen appeared a few days back, mostly in apps, and couple of days back throughout android. Since the headphone jack has been damaged for about a year now I suspected hardware issue, so in order to remove any doubt went to back to stock.
Important to note here, before going back to stock I noticed I could not get to download or recovery mode by physical buttons, but I could go in recovery through reboot app.
Anyhow, backed up data on TWPR, and proceeded to pick the return to stock option on CM13, which returned the phone to stock cm13. The flickering persisted, even in TWPR, so I believed it was a hardware issue and decided to restore back my image.
Sadly the restore failed (error message "extractTarFork() process ended with ERROR255"), instant reboot and here we are now.
Bootloop with lg and cm logo, no recovery, no download mode, no backlight, not recognized on device manager by windows (have installed all drivers), appears as charge only interface on devices and printers, not appearing on adb cmd, not showing on Ubuntu *but* using lsusb command it appears as lg g2.
Would try the “LG G2 is UNBRICKABLE NOW!” method, but there is a stubborn screw with damaged head and lack of img files (since cyanogenmod site is down) that prohibits me. Lastly I would go for a new motherboard hoping it would fix the problem, but to be frank it costs as much as a new phone, plus they are out of stock for months now.
Any help is kindly appreciated, and thank you for reading so far.

Thank you for your suggestion, sadly the output of ls /dev/sd* does not include the lg g2 compartments so the beforehand mentioned method cannot be used.
The only time the lg g2 is recognized as such is by the lsusb command, which gives the "LG Electronics, Inc. G2/Optimus Android Phone" result and within the usb settings on a VM from a windows host.

LG G2 won't turn on

Hi.
To start off, I'd like to say im no expert with phones, I had phones mostly to call, watch videos and listen to music, and this is my first attempt at doing all the stuff I will be describing now.
From the beginning:
I bought a seller refurbished LG G2, which worked fine when I received it, I had to do some updates which my phone found automatically, and it ended at OS version 4.4.2.
I wanted to finally have a decent but cheap phone, however it couldn't play some games I wanted to play and thought "Maybe if I update OS to something new, it will work, and it looks better"
Here my journey to update the phone to Android 11 started.
I was looking at many different videos and guide and everything, how to root, first time I rooted was by accident, only later a better video instructed me how to do it properly, then I installed the trww or whatever its called. then it didnt work properly after using that recovery to install android 11, so I had to flash it to some old version I found for my device (My version is LG D802 btw). For some reason it now had only 11gb of space, instead of 32gb. Anyway, I tried installing root and twrw thing again. After getting root and the recovery program I clicked reboot in its options and now my phone is having an issue.
First off, I left it to charge over 9 hours. If its NOT connected via usb it does nothing, power button, volume buttons do nothing.
I tried connecting it to my phone to flash it, but nope, after few seconds it says my phone disconnected from the usb and try again, even tho it is connected and I can see in device manager that it's seen by my PC. Now, I tried to enter the download mode manually, and it worked.
It says that it's rooted and B0 above it (this number was going down over different roots, twrw installs and flashes and such, no idea what it is.
I tried to flash it again since Im in download mod, however now the main issue appeared. It goes well for 40% of the flash using the LG flash tool 2014, I can see the progress in the download mode on the phone's screen, however once it reaches that certain point it just resets and the program treats it as disconnected.
Now when I have the phone connected via usb it just flashes red between 1 and 3 times, LG logo shows up for several seconds, then it turns off, and repeats the whole process.
During the flashing, software instructed me to remove the batter and try again, so I looked up how to remove it, did it, put everything back together, and its still the same.
Please tell me what to do, I've already spent over 10 hours trying to fix it and I just bought this phone...

hi... if your phone flashes LG logo - i'd recommend a full TOT flash of the original Lollipop image as a starting point...
just make sure you download a proper TOT file for your d802 device (32gb model)...
you'll end up with a working stock Lollipop rom which you can later root and flash a custom rom (i.e. Lineage 18)
Stock TOT file is usually about 2.6-2.7GB in size (at least for my 16gb model)
this youtube video shows how to do it and what is required for the process...
i think there is also an older thread here on XDA on how to TOT flash a G2 device (try to search it)

LG G2 D802 United Kingdom Open - unbrick?

Hey everyone,
I'm very new to Android development and XDA, but a few years ago I bricked this LG G2 and I don't really remember how, except that I rooted it and tried to install a custom ROM, which obviously didn't work.
I have tried a number of different guides on these forums, but somewhere or another I get stuck on them.
[HOW TO] Fix your soft-bricked LG G2 (All Variants)
I'll be very specific, something most people lack of. Okay lets get to it, I recently bricked my LG G2 (D801) by installing a ROM that wasn't compatible with my model. I fixed it by doing the following steps. This worked for me using Windows 8.1...
forum.xda-developers.com
With this one, although the device shows up in Devices and Printers, neither Fastboot nor the LG Flash Tool detect it. I have installed both the LG Mobile Driver and the LG United Mobile Driver.
“./fastboot devices” is empty.
I have the TOT file and the DLL that the (patched version of the) LG Flash Tool requires.
I have an Ubuntu 20.04 install as well as Windows 11. I can get into Firmware Update with a USB icon ("Do not unplug the USB connection until the process is complete. 0%." ...etc), when I turn it on normally it shows a battery made out of grey and white bars and a percentage, and sometimes the LG logo.
If you need to know anything else don't hesitate to ask \
Much appreciated,
ninjadev64

use a usb 2.0 port, update adb/fastboot, update drivers, remove previous related devices using nirsoft usbdeview. try using a windows 7 or earlier system. can you manually get into recovery? if so update to latest blastagator twrp which should be 3.3.1.

- I was using a 3.0 port, although it still showed up in Control Panel - I’ll try with a 2.0 port today
- I installed “Minimal ADB and Fastboot” and the drivers yesterday, so they should be up to date
- I’ll use usbdeview too
- I can’t use an older system unfortunately
- How do I get into recovery?

Recovery: With the device powered off and usb unplugged, hold Volume Down + Power. When the LG logo appears, release both buttons and hold Volume Up + Volume Down.

Ok, so I got into a factory reset screen that way, I said yes to factory reset, is that the right thing to do? (@DvineLord)

ADB recognises the device, but it's unauthorised. And I obviously can't boot it up to authorise it.
Factory reset just got me back to the LG screen for a long time, so I powered it off again.

Also, when I try to change the COM port to 41, when I click Advanced in Port Settings, it just stops me with "You must have write privileges in the registry for this device in order to modify the device's advanced settings".
I can't find the right path for the device in regedit to follow these steps: https://forums.techguy.org/threads/need-write-permission-for-com1-port.577543/#post-4756991

Were you able to get into Recovery? or did you get into Bootloader/Fastboot/Download?
Bootloader/Fastboot/Download: With the device powered off, hold Volume Up and connect the USB cable.
You want to be in Recovery like I posted above. Do you have TWRP on your device?

The recovery method you said to try got me into a factory reset screen, as I stated. All the other recovery methods I saw online didn’t work, so maybe I have no recovery?
I said in the original post that I can obtain download mode. I recognise “TWRP” but I’m pretty sure I botched it up while installing it, because I didn’t know how any of this worked, 4 years ago.
Thank you!

Unfortunate you can't get ADB/Fastboot working.

Soo... what can I do?

Try to recall as closely as possible the exact steps you used to modify your device. autorec, ioroot, stump root, avicohh, stock build you were on, custom rom you tried to flash, custom recovery, bootstacks, custom kernel, etc.
Odds are you'll have to try again to flash back to stock, something which I haven't done yet.

Unfortunately all I know is that I tried to install a custom ROM, scuffed up when I was installing twrp, the ROM didn't work and now I have no recovery to fix it. Flash back to stock *is* what I'm trying to do (that's your third question/point which I've already explained in the original post).
If anyone with the same problem visits this in the future, please save this post and share your solution if you find one, cause I'm still stuck!

hope you get it flashed back to stock. make sure to do the first 5 things i listed in my initial post to see if that helps you flash back to stock. the data cable can also make a difference sometimes too.
