thats not even close to a hard brick it is in bootloader mode do not let it die keep it plugged in because if the battery dies then you have a real big problem im not sure what to do after this but i know you dont want the battery to die
well that's reassuring
Keeping phone plugged in. Now if I can get some tips as to why I cant get it to communicate with ubuntu in this bootloader mode to push the files I need. Any help anyone? Please. Where I go from here?

if you manage to install the driver the rest should go easy.
It's weird, on some systems it wont install the driver properly(adb) but google nexus driver installs fine.
i was hoping so

Ultra brick G2 vs980! T_T
Good night lords of XDA!
I come to you after exhausting all that I could find and try, hope you can enlighten me, you would save a new G2 that is about to become a gleaming brick:
Summary: I have in hand a Verizon LG G2 vs980, with the intention of using it in Spain. After a bad flash a ROM for a different model, you could not access recovery mode or download mode, only fastboot.
Thanks to this great tutorial, I could flash by ADB and fastboot files an official ROM for this G2, but after a correct process, the G2 restarted and only shows "Security error" before shutting ...
I still do not have access to recovery or download, and now not to fastboot. Only allows me to access the screen "Factory reset", but in doing nothing changes.
How could re-flash a recovery or something like that allows me relive my G2?
Thank you very much in advance. You are my salvation. XD
PS: I apologize for any clerical error or misused term. I do not usually write in English.

Lg g2 D802 32GB
Got my phone bricked once when trying to install lollipop rom.
After successfuly restoring it and getting the 16GB error and fixing it I restored to stock 4.2.2 and in recovery accidently installed the KK bootloader and rebooted instead of installing the rom.
No download mode.
No recovery.
First phone booted and then the screen turned off and was only sounds (Booting in, connecting to pc, etc.)
Now nothing.
the only thing I managed to enter is the Hard button mode....
I tried every forum,thread,files,method mentioned exept the "Open the phone to pieces and tinker with it" method mentioned here somewhere.
If there is some hope for me before going to a repair shop and hopefully someone there smarter than me and can actually fix it... would really appreceate every advice you might have on the matter.
Thank you.

adb reboot recovery/bootloader/reboot/fastboot
Until I saw some writings and phone entered this state:

Stay calm buddy, LG G2 is unbrickable, I had the same problem, I thought that I have bricked it, but fix was simple, I had only download mode, but KDZ restore stucked, what I did was just wait some time, cause LG flash tool has some problems with loading files, it just takes some time, so load it from your folder(kdz) , then wait some time and after that just start it, then you have to be patient cause it takes some time, I experienced some errors too, so just dont unplug it and wait, relax, it works
I have D802 32gb czech version
I flashed v30a Italy version and it works
just flash the right version

does the phone being recognized in windows when you start adb and using adb devices command?
you can use this to install ADB and run it from CMD in windows:

No it doesn't, i have ADB, i know how to use it, i already saved one D800 that was in Fastboot.
Problem is, i used the debrick method, i succeeded, but now the device is recognized as LG but the screen stays black. It's acting a bit weird, it flashes with LG FLASH TOOL, although i believe it's not even in Download mode, but the screen keeps staying black.
Stuck at logo

Hey Guys,
Hoping someone can help me out here. I've got a friend's LG G2 and I'm trying to help him get it working. When I first got the device, it just booted to a black screen and when plugged into Ubuntu, it would show 15 or so drives that were unable to mount. I followed a guide to fix through Ubuntu and eventually got it to boot to where it would show a black screen with small white text indicating it was in fastboot mode. In fastboot mode, I followed this guide: https://www.youtube.com/watch?v=YEqEE9Qb8Sk and eventually got it to boot showing the LG Screen. I am able to get it into Download Mode and Recovery mode (but performing the hard reset doesn't work, as when the Android Man screen loads up with the progress bar underneath it stays on the screen for about 15 seconds before restarting and staying at the LG logo screen. No matter which Tot file for the D800 I flash through LG Flash Tool, it fails after about 3 seconds stating Cross DL (850) to (800). He had tried to use an G3 Rom on the device, which is what bricked it in the first place. I've noticed that the device is showing a blank IMEI in the flash tool as well. I've also tried using the DLL posted in @hyelton 's guide (LGUP_8974.dll) and it still gives me that same error.
Hoping someone here might have an idea of what I can try next to get this thing working again.
Thanks!
Mark
Fixed
All right guys. After much painstaking searching, I've finally found a solution, thanks to THIS REDDIT THREAD. I used a hex editor to modify the first line mentioning "D800" in the TOT file that is provided along with the link to the YouTube video in my OP, changing it to "D850." I used Hex Editor Neo to do this. This should work with any LG G2 that has had incorrect firmware flashed on it when you are getting an error of CrossDL from the LG Flash Tool.
my phone LG G2 D802 International Version was running perfectly fine i tried to flash another rom by LG FlashTOOL and in the first i got soft bricked on that fastboot screen i recoverd it by ADB (fastboot.exe)
fastboot erase recovery
fastboot erase laf
fastboot flash laf laf.img
and then i tried to reflash it then i got this mesg on screen

Please Help me somebody ... i cant afford to buy new phone i just bought this phone a week ago ..
Having same issue ! XDA forum experts always helped me with every situation with my phones. Expecting help this time as well from you experts.
Same here, enyone can help, i stuck with the sam message, presing vol- just rebots, and vol+ sends message "jump to download mode" but i cant flash stock firmware
i have the same problem any help ??
I have the same issue too, can anyone help?
I heard that this can help you guys. Use the search option there and try to fix it. Actually i had the same problem few months ago, but for me mew motherboard was the solution... If you're device is under warranty send it saying it failed while taking OTA. Good luck...
lg g2 critical error
I have done a flash to my g2 32gb d802 and it suddenly entered into critical error not going into any of thefastboot mode or download mode even though it is giving me options.....please any one help me out to get my phone back to normal ........
PM me if you guys need help.
I had the exactly same problem, and I had to go to afterservice center to repair. Engineer told he would wipe everything and install new rom. but He failed to write rom so he simply changed mainboard.
At first I had thought about open my g2 and makes it go into qualcomm download mode by short-circuit.
the reason I didn't was my warranty was still available.
I tried every method to make it boot into recovery or download mode but I failed. In my opinion, you may try short-circuit method for last solution. In this situation, even linux doesn't mount rom's storage section. Only if you can make G2 recognized in Linux, G2 will revive.
good luck.

The best way to go if you do not have a warranty is to short circuit the board and get into Qualcomm ... 9006 mode. However, when you get the demigod error plug in you usb and click up and it should start download mode even though it doesn't show it.

I got into this error after I had previously recovered into qhs_usb9006_bulk mode from a hard bricked D801, by shorting the capacitors on the main board. After entering qhs_usb9006, I used srk tools 2.1 for my phone, and after they finished, I tried entering download mode, only to get into this error. I really don't know what it is to say about this. Everything turned wrong with this phone, it went from simply failing a .kdz, to stock .tot, to hard brick, and now to this error, whereas it should've just enter the download mode, as for the 99,99% of the others. Any help would be really appreciated. Thanks.
L.E. I shorted the capacitors again (the one i the middle, like I did the first time, when i got into 9006 mode. 5000 and 5004 didn't work for some reason). This time I got into dload mode, which is 9008. I'll try to recover the phone from here, with this method:

i had this problem while trying to return to stock. Fixed it by following this guide http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404 . it needs some hardware tampering though. i tried and tried but i cant flash the phone any other way. the way i understand this is due to bootloader being corrupt.
I installed autorec from playstore solved all the problems
Than you! autorec worked for me too
Can someone post a KK baseband for D801 (T-Mobile)? I'm on D80120a software version with unknown IMEI and baseband (the phone is a D801 refurbished into D802, I more than hardbricked it by flashing wrong .kdz, got it recovered through shorting pins, 9008 mode, got download mode, D80120a stock, root, twrp, after a very long and painful process of about 1 month). Now I have to make use of QPST, but I have to obtain a valid baseband first. Of all links I've stumbled upon, only 5% or less of them are still working, so I only have one flashable modem, in twrp recovery, which corresponds to D801 jb version.
http://downloads.codefi.re/autoprime/LG/LG_G2/G2_modems
cloudyfa kk_baseband_D801 only make my phone restarts like crazy.
I'm simply stuck and pray for some devine help.
Thank you.
Weird enough, I flashed a canadian modem and I got both baseband and IMEI. Why did I do that in the first place? Because I remembered that before all these things happened to my phone, the baseband was M8974A-AAAANAZM-1.0.190082, which corresponds to D803. So I said to myself what can happen by flashing the wrong modem? Boot loop, easily fixable with the phone in it's current state. But again, after 1 month of trouble with the phone, I'm back to what exactly started it in the first place: phone seem to work OK but it has 2 huge problems: WiFi extremely weak (2 meters away and a wall or 5 meters away and no wall a and I lose the signal in both cases; the 2nd is wit the GPS - 20-30 meters error). No idea how should I adapt the radio to Europe region (by keeping the canadian one and change the settings, if it's even possible/fixable this way or if this even does make any sense).
I had to do a hard brick fix to get it into the QSUSB mode to flash TOT.
Have you tried using LG Support tool to put it back to stock?
Sent from my LG-F350K using XDA Free mobile app
I was trying to update with LGUP application for firmware update but didn't success, so I removed the USB cable and pressed Volume down and power button to restart. But it went straight into Firmware Update and LGUP application can't find the port.
So, my phone is stucking in Firmware update screen, please help me how to restore the firmware and get out from Firmware Update screen, many thanks and greatly appreciated.
Hold the power button until you get a black screen. Download LG Mobile Support tool and the LG Drivers. Plug USB In and then hold the Power + Volume Up key. On your screen, click Upgrade Recovery. From there, you can do a factory reset through download mode of your phone.
Enter download mode and connect the phone in the PC. Download LG brige and open it. When you are inside the programe you will see a window of Software update enter here and there is an option that is for bad installation otas (to reinstall and correct errors). Use this and I think this will handle.
Another option I think is using LG Up you will see your device in download mode. Try to enter download mode and see if this works also.
Thanks both - I ran into a similar situation. I pulled down both the 11a and 14a KDZ files, and used UpperCut and LGUP to flash first the 14a and then the 11a image. Unfortunately in both cases after LGUP does its thing, I'm getting the LG logo, followed by fastboot screen.
I cannot reboot to get past it, and I cannot flash recovery (it says the boot loader is locked). I cannot flash the Unlock.bin from LG because apparently the KDZ re-enabled the software lock prohibiting bootloader unlocks.
So I'm suck with a phone that will only boot into fastboot, stock recovery or into download mode, and I cannot figure out how to get back to something functional. I've tried reflashing with LGUP - that doesn't work. And the LG Bridge "Update Error Recovery" option gives an error "Connect your mobile device to the USB Port" even though it is, and the LG USB drivers are installed.
Would appreciate any pointers someone could offer.

I have the same issue - I was on Lineage os and flashing the OTA update caused bootloop to recovery. So I wanted to flash back to stock using LGUP and 14A. I did that before without issues.
This time though all installed fine but after reboot the phone immediately goes to fastboot, exactly as described above. I just spend several hours trying to fix it but with no results. The LG Bridge won't recognize the phone no matter what I do in Windows (tried 3 different PCs). On a Mac it will start connecting and will end up saying "you need to enable MTP connection".
From what I garther the stock rom flashed fine - the factory reset works, even shows "erasing data", the LG UP recognizes the phone as 14A (I tried 11A, 13A too - seems to install fine but goes immediately to fastboot after reboot).
The only thing I realized I did different when flashing the stock rom with LGUP was not using the original LG USB cable. But reflashing with original cable makes not difference now - still going to fastboot.
Any help would be greatly appreciated.
Have you guys been able to do the Upgrade recovery in the LG support tool? Did it work? It starts fine for me but after downloading the recovery file I always get and error, see the screenshot.
I was able to grab the kdz file and tried to flash it with LGUP but still the same thing. It seems like it flashes fine but after reboot it immediately goes to fastboot

Sadly I'm in the same boat as well. I'll pull some of their error messages I've gotten with LG Flash Tool this afternoon. I've tried 2014 and 2017. Both to no success.
I suspect it may be something with the /misc partition. Im going out on a limb, but I'm guessing that the AOSP and Lineage ROMs may touch misc. That partition may have some key identifiers for the LG tools. And the KDZ doesn't have a misc partition embedded inside it.
I was hoping the kdz file I was able to grab from the Lg Support tool would be different from regular stock rom 14a that is available around the internet but it appears to be exactly the same file (based on the file size). My original hope was that the file would support "Refurbish" option in the LGUP tool but it only works with "Upgrade".
I wonder if the "Refurbish" option would fix this and re-flashed all partitions - if only we could find a kdz file that would work with the refurbish option. So far all files I tried (11a, 13a, 14a) only support the upgrade option.
Thanks for all of your helps, I used LGUP and WondersMobile application on the computer and LGUP can not see the port. I did un-install the WondersMobile and LGUP can see the port and finally upgraded to latest firmware.

I too am having same problem. I've tried all the images from 11A to 14A, all of them flash with no errors on LGUP and every time LGUP detects the phone as having the last version flashed. Unfortunately, the phone also boots to fastboot every time. Nothing else to add to your descriptions at this time I'm afraid...

Sadly I'm in the same boat as well. I'll pull some of their error messages I've gotten with LG Flash Tool this afternoon. I've tried 2014 and 2017. Both to no success.
I suspect it may be something with the /misc partition. Im going out on a limb, but I'm guessing that the AOSP and Lineage ROMs may touch misc. That partition may have some key identifiers for the LG tools. And the KDZ doesn't have a misc partition embedded inside it.

I am absolutely positive my problem is at least in part due to a messed up /misc partition though. @gqo actually described what I did pretty thoroughly in his thread, albeit in a G5. Post #9 has the fix but it didn't work for me.
I've also stumbled upon a menu under the Firmware Update screen that I had never seen before and cannot fin any mention to... Would any of you guys know what it is for? It reads something like:
Code:
** SELECT MENU **
** Select : Power Key(Long) **
** Move : Power Key(Short) **
-> MA-USB(WIFI) DL
POWER OFF
PHONE INFO
BACK
Okay, I figured it out. The menu, at least the first option, appears to be for Wi-Fi firmware update. I wonder what file the phone actually downloads... And if it would be able to fix our phones. The only unprotected network I had in hand was a mobile hotspot in my not-so-LTE Nexus 5, so I got as far the firmware download start but didn't risk it on such a slow and unpredictable network. On top of that my Nexus 5 has also gotten pretty good at bootlooping, that's why I got this G6 in the first place. If anyone out there has a reliable unprotected network and nerves of steel it could be interesting to see if the outcome of this update is different from the LGUP one.
How do you access this menu?
What I started working on yesterday is trying to build a image file for the Qualcomm Flash Image loader and see if I can flash the phone using this tool... But I have never used this tool before, right now it does not detect my phone - I need to work on that + see if I can correctly build the image file from kdz. I found some youtube step by step tutorials so we will see. I will post update on the progress tonight or tomorrow.

I'm not sure if there's a better way to do it, but I access it by removing the usb cable after I successfully get in Download Mode. Then I'm not sure if there's any specific key combo, I've been randomly pressing the power and the volume down buttons and at some point I get into that menu. In the menu though, for some reason, I think I can only select an option if I long press both the volume down and power buttons. The "POWER OFF" option has come in handy because so far is the only way I can actually turn my phone off. The "PHONE INFO" hasn't worked for me yet. The menu also reacts when you add/remove the microsd card... I wonder if it can be used for something other than a WiFi firmware upgrade. I haven't had the chance to connect the phone to a computer to see how the device is recognized, if at all.
And that image you're working on sounds like a neat idea, I wish I could help but I'm afraid I wouldn't have the skill. I may be able to test though. Anyway, Godspeed!

I'll play around a bit and see if I can land on this menu. At this point I'll try anything. I'm on an iPhone until I get this fixed - so I'm motivated!
I can setup an open guest network off my main wi-fi this evening and see what I can find out.
EDIT Sorry, I tried playing around here, but I couldn't figure out how to get back into the the menu you uncovered. If you could give some instructions on how to do it, I'm happy to give it a shot on my device.
I was able to access the menu today...what worked for me was at the firmware screen unplug the usb cable and then press volume down and power button three times quickly. I tried to connect to a wifi and it does not really do anything. I think it just establishes wifi connection but it does not download anything on it's own - it's waiting for another connection.
Also I got stuck with building the image file from kdz, it has no information on partitions. At this point I decided to ship to LG for a quote and will see how much they will ask for a reflash.
I got as far as selecting a network and getting some sort of a download start screen, but I interrupted it right away so I wasn't sure the download would actually go through... Apparently it does not. If this menu has some sort of flashing capabilities though, it might be worth checking how secure it is. If someone can get it to download and flash a modded file perhaps there could be a chance of flashing a custom recovery or something... I'm thinking about those guys that have an unlockable bootloader (which we ironically also have now).
Anyway, all of this goes well beyond my skill so I followed your example and submitted a repair service request to LG. It'll take quite long but shipping is free, so I figured I'd give it a try. I'm assuming this is an easy fix with the right software tools, so I hope LG doesn't overcharge for it. I'm even half hoping they'll do it under the limited warranty... If I recall correctly unlocking the bootloader doesn't immediately void all warranty, there's room to prove the bootloader was never actually unlocked. And after all LG does say that once unlocked, it cannot be undone and our phones are, in fact, running stock firmware and have a locked bootloader.
Update: My phone was received today by LG. In LG's Track Repair page, the status briefly showed as Undergoing Diagnostic but quickly moved to Repair In Progress, it's current status. Given that LG was supposed to contact me in case the repair was not covered by the limited warranty, meaning that an extra fee would've to be paid, I'm assuming the phone will be fixed (if possible, that is) free of charge. I will update you guys again soon, but if anyone out there is still struggling with this issue I'd recommend considering sending the phone to LG.
I have the exact same problem. Please keep us in the loop of what happens to your phone with LG
My phone has been received by LG for this issue on 9/26. It quickly moved through diagnostic to "repair in progress" on the first day plus showed ETA back to me in 6 business days. Ever since that it's stuck in that mode, no update or contact from LG. I check the status every day - every day it says the same - ETA 6 business days. It's been a week and half now with no update. I kind of expected it's going to take 2-3 weeks but annoyed that they say 6 days ETA and then you don't hear from anyone for almost 2 weeks with no change in status.
Update #2: The status finally moved to Shipped To Customer. I haven't been contacted by LG yet, so I guess the phone could've been shipped fixed as much as it could've been shipped as is for being unfixable. Either way, I wasn't and most likely won't be charged. FedEx hasn't got an ETA for the delivery, but I'll let you guys know as soon as I get my phone back.
Edit: Got an e-mail from LG. It reads something like:
Defect: Software failure
Payment Type: NOT APPLICABLE
Repair Results: S/W upgrade (download)
Repair Cost: $ 0.00
Warranty Status: In Warranty
Tax: $ 0.00
Total: $ 0.00
I guess I got away with it, I hope you guys do too.
