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

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.

Okay, this is must be my first thread since I join this lovely forum.
So here is the deal, this is my previous phone that I gave to my sister not so long ago, she has this not-so-bright wise *ss who try to fix her G2.
Sadly, he flashed the wrong rom, this is LG F320L and I think he flashed with F320K (based on error message that I got from the LG Flash Tool when I try to fix it)
This is the story so far :
1. the first time i got it on my hand (after get wrong-flashed that is ) :
- the phone is cannot boot, it stucked on black screen with fastboot command, try to go to recovery but not working, keep going to fastboot screen
- but i can still go to download mode (if I press vol UP while connect it to my PC) but somehow my PC will not recognize it
2. So I browse so many tutorial here and I end up erase and then reflash the stock recovery via cmd fastboot command, I'm 100% sure that I flashed the correct stock recovery file
- the process kinda work, the phone is able to go to recovery screen now although still cannot boot to system
- i still can go to download mode but the PC still didn't recognize it
- however, now the phone is being recognize by my PC if i plug the phone (without pressing anything on the phone), but gave me error code on the MTP driver
3. So next step I try to flash it via kdz method, didn't work of course, since my download mode won't be recognize, and then i also try to flash it via TOT method, also fail (again)
Note : on TOT method I try to flash it while NOT on download mode, since it will not recognized, it gave me error message that i try to cross flash or something. It says that I try to flash F320K to F320L (hence I assume that my sister's boyfriend flashed the wrong rom and got bricked)
also please note that while i'm did this i already make sure that i change the port setting to port 41
So now i stucked here, without the working download mode that can be recognized by my PC i think i'm start to running out of option to fix this phone
Please point me to the right direction good people of xda, please, thank you in advance

Okay, so at this moment does the device try to mount quite a lot of partitions? Also does it give any errors on the screen if you power on without trying to boot to download mode or recovery? Ideally we want to see something along the lines of security error.

thanks for your reply, i really appreciate it
well, you're right, it does give me errors when i power on (without trying to go to download mode or recovery mode)
so when i power it on, it shows LG logo then the image goes like corrupt, at first it kinda like shaking then it went blur and last it disappearing, leave the screen into just blank screen.
but my PC recognize it on this moment, just the MTP driver that wasn't
about your first question i'm afraid i can't catch what that means

Hmmm. okay, so what does the pc recognize it as exactly in device manager? Also if you connect the device do you get several pop ups stating that the mounted device needs to be fixed? It's just that if the partitions are being mounted we can reflash them manually using DD commands with ubuntu.

Right, you need to follow this guide i think. Ensure your read it fully before you attempt anything. Now, the lollipop update apparently changed some partitions so I would flash the bumped twrp from the development section instead of the 2.6.3.2 version recommended. Then once you can boot into recovery flash the rom recommended in this post

it's just like the pict that i attached
about the pop ups, no.. i don't think i got those, the only pop ups that appear was the small notification on the bottom right panel that the drivers is being installed, and keep failing on the MTP driver, maybe that's why my PC can't recognizes it under the download mode

if you open disk management what does it say about the g2? also did you install the universal adb driver at any point? http://forum.xda-developers.com/showpost.php?p=51265001&postcount=30 here it states that installing the universial driver will show your device as a samsung.

okay, i just checked on disk management and it appear that my PC doesn't recognized the G2, what makes it weird, at the same time it recognizes the G2 on device manager on ports (COM & LPT) on port 41, about the adb yes, i do believe i did that long time ago, though i forgot what was my intention of doing so

Hmmm. im stumped. I think its a bit of a catch 22 here. What i think has happened is that the rom flash that was done has changed some of the partition layout, but the methods of fixing that issue is either with DD commands from a custom recovery (which you dont have and cannot flash) or with DD commands using ubuntu when the device is auto-mounting all of your partitions. Its worth a look if you have an ubuntu disk around, if not download here, burn to disk or mount it to a bootable usb and see if ubuntu has any luck with it. Either that or try installing any drivers you can on the pc to get download mode working.
there is also this as a last resort but i've never had to do this so i cannot vouch for it :-/ Good luck pal.

Hello guys,
So I bricked my D802 , how? first it was bricked because of a wrong version of TWRP, untill here no problem, i tried many tutorials on how to go back to stock rom, then i found that it was a Qualcom thing problem, so I found that tutorial about replacing the .img files etc... , pretty easy, i could enter the recovery menu, but it had no rom, i downloaded the stock rom kdz file , started flashing it, then, for some dumb reason the flashing stopped, I ... plug out the usb cable... I didn't notice untill I saw that the program froze, and now the phone is stuck at the LG logo, impossible to do anything, pc doesn't recognize it, can't go to recovery menu, can someone help me please? or at least tell me if I should just throw that phone or keep it if it has a chance of living a bit longer

I had a very similar problem with it getting stuck at the logo after pushing supersu to the phone. I followed Supersport every single step of the way in his video. I think his links are the only valid ones online now, so just download them and reflash your phone. If your G2 is anything like mine, drivers will never appear to be installed correctly and it never restarts, only shuts down.
His method is:
1) Download and install LG drivers on PC
2) Download and install the flash tool and patch it
3) Download and load the .tot and .dll files into the flash tool
4) Enter download mode on G2 by holding volume up while connecting USB
5) Switch G2 Com port to 41 in device manager
6) Once Flash tool shows that all ports are ready, power down G2 and disconnect
7) Hold volume up and reconnect to get back into download mode
8) LG Flash tool starts flashing
9) Complete
Note: If your G2 was screwed up as bad as mine, it'll say failed but all the main system files will load to the device before it restarts and it'll even shut itself off while doing it's installation on first reboot. Mine somehow was still revived from this state with his method.
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.

I reinstalled LG drivers, and i can see "LGE Android MTP Device" in Device Manager and it has no problem. (There is no yellow exclamation mark) But still, my computer can't see my phone. And i tried install stock rom with Flash Tools again but i did not work. Stuck at %2 again.
I seem to have encountered quite the predicament. My VS995 doesn't boot any more. It shows the "Your device is corrupt. It cannot be trusted, and will not boot" message that it always has, but then it reboots and shows it again, and repeats that process forever. I cannot boot into TWRP or Fastboot mode, but Download mode still works. Upon entering download mode, the little box at the bottom says "633A B50 Modified" and the loading bar says 0%. I don't have a Windows computer (all my computers run some variant of Linux Mint) and have been using a Windows 7 VM in VirtualBox. Device manager and LG Flash Tool recognize the phone, but LG Flash Tool fails to flash it at 4% claiming an "RX Timeout" error no matter what I do with it, and the little box in the phone's download mode changes to say "633A B25 Modified." LGUP (with or without Uppercut) simply says "Unknown [COM41,]" followed by "You must select a known model, please."
I tried following this guide (https://forum.xda-developers.com/v20/how-to/guide-lg-v20-to-life-t3827732) and several others around the internet to no avail. Does anybody have any idea if this phone can be saved? Or is it destined to the dump?
Since you still get the "device is corrupt" message, you still have the engineering aboot, so you have full fastboot.
Download the KDZ for you phone and extract it. (Search, there are lots of good posts on extracting KDZs)
Boot to fastboot. With the phone off, hold vol DOWN and plug in the USB cable.
fastboot flash twrp.img recovery
fastboot reboot
Then use the key combo to try and get to TWRP. If you can't then you probably have a hardware problem (bad NAND).
Whatever you do, don't do anything that will overwrite aboot or you have a 0% chance of fixing your phone.

You boot into fastboot by holding volume down and plugging the phone into a computer, correct? Whenever I do that it just shows the "device is corrupt" screen and does the reboot loop. I can only ever get to download mode.
Try this no guaranty it will work start LG up on your computer plug in device then remove battery from device and then reboot your computer without killing LG up then put battery back in phone and restart LG up......see what happens.

When did this start? Did you do anything to your phone, or did you reboot it and it just started doing this?

For reference, I bought it used (but tested working) on eBay a month ago. First, the SD slot corrupted my SD card and then started saying the SD was not compatible with the phone. Then the SIM slot stopped reading the SIM, so I restored a backup I had made a couple days ago in TWRP and it didn't fix it. I tried dirty flashing the ROM, then clean flashing a few other ROMs, but nothing fixed either slot. After a little more of this flashing, I rebooted and the phone started doing this.
It sounds like with the flashing you did, you restored the stock aboot while you still had a modified recovery (TWRP) and modified boot (rooted) .. that is the reason you can only get to download mode -- since laf wasn't modified.
The RX timeout you are getting sounds like you have a marginal USB port or cable, you need to try flashing on another PC, and don't use VBox. I think you can still save your phone...

If your bootloader is unlocked then you can fix your phone, if not then i had the same problem, repaired it from market, I think he used some kind of box(maybe octopus) and got it fixed.

I installed Windows 7 onto a laptop and installed the programs on it. LG Flash Tool still failed at 4% claiming the KDZ and DZ didn't support something (I couldn't read it because the box was too small and it didn't scroll) but LGUP via Uppercut recognized the phone and flashed it! The phone booted to a screen with a big red 2 on it, then I reflashed it with the same KDZ in LGUP and it booted, but now it's bootlooping. I waited about 20 minutes and it didn't boot beyond the Verizon boot animation.

It sounds like you have a hardware problem with the NAND chip on your phone. That is the only thing that makes sense as to why you were able to get it to boot, but now it bootloops.
The data on the NAND is good enough for one boot, but then becomes corrupt....

Could the bad NAND have also caused the SIM and SD slots to stop functioning, or did the phone just basically disintegrate in my hands?
The firmware could have had problems, or whatever hardware failure messed up your NAND also toasted those.

Well that stinks. For the month I owned it, the LG V20 was the best phone I've owned so far. Oh well, thanks for helping me.
Same Boat

I was hoping there was a solution to Kiraisuki's post as I having similar symptoms with my phone.
My V20 is a US996 BPT with a locked boot-loader. Mine will crash apps, stop at 4% via LG Flash, then reboot into "Your device is corrupt. It cannot be trusted" then lock into the LG logo until I pull the battery 3 or 4 times forcing a restart. I also have the same results with LG Bridge.
Does the NAND chip itself fail or could the chip be reflowed to the board with a little precision work?
