I attempted to flash the Marshmallow update via TWRP. The flash seemed to finish successfully, but upon rebooting I am stuck on the LG logo screen.
I am able to get to Download mode, but don't know what I can try from here.
I have already tried the LG Flash tool and it fails at 9%.
Any help would be appreciated.
TIA
Is there an error message at 9%? Have you tried LG Bridge or UP?

At the 9%, it says Upgrade stopped due to an error.
LG Bridge won't see the phone properly. It initially says connected but then drops the connection.
I am not familiar with UP, is that something I should try?
EDIT: LG UP Worked. Thank you very much!

I have the exact problem, LG Up successfully completes flashing and the whole process, did it with LG Bridge too but phone still can't get past logo, maybe my batter is drained?! I can enter in download mode and my pc, LG Up and LG bridge all see my phone as Lg H812. i am desperate.

Dear All,
I flashed CM7 SK7. I ran well but my phone ran out out battery then it is dead. It stuck at the LG Logo. I tried the unbrick guide but using KDZ_FW_UPD but it reboots to the LG logo before the process is finished (90% then reboot).
Please advise.

You finished flashing before it died or in the middle? Have you tried R&D Test Tool or adb reboot recovery?

It reboots when it is flashing but the software update continues on my computer.
R&D test tool hangs; not sure how to do the adb thingy, will search for it.
Now, it stuck at the LG logo. Further advice will be appreciated.
Give it some time. The first boot is quiet long.

The problem is, it boots before the flashing process is finished so the flashing process was not completed. Tried the R&D test tool. It is the same as KDZ, reboots when it is 90% completed then the tool continued the remaining 10%. It stuck at the logo now. Should I keep waiting?
PS the four buttons are on and off now.
That sounds like the same state my OB got to when I borked flashing init.d scripts.
- To recover you need to have adb installed on your computer
- on boot, connect your phone to your pc via usb
- on your computer, issue/spam 'adb devices' until you see your device detected
- issue 'adb reboot recovery' or 'adb reboot bootloader' and wait for it to restart
i had to wait about 40 mins for the issue to get through but i was able to go back to recovery and reflash

Hey guys,
I accidentally selected the OTA that popped up on my phone while on a Stock ROM and now my Verizon LG G2 is stuck in a bootloop with CWM Recovery 6.0.4.4 I have tried to wipe everything and install a older CM ROM and Gummy ROM to see if that would get my phone to turn back on and it doesn't. I have researched many threads to see if there was a resolution for my issue, but everything that I tried did not work. I have a iMac and a Windows laptop and I have tried many things with Terminal and Command Prompt and nothing seems to work. I don't know if I am doing something wrong with ADB or if I am simply just missing other things, but I am trying to get my phone back un-rooted and back to stock to get my phone replaced under the warranty. PLEASE HELP!

Try the LG tools for bricked G2. Its somewhere on these forums. All you have to do is plug up to a computer and flash the stock ROM with the tool.

I tried the LG Flash Tool on a PC, but it gives me an error message LG USB/Parallel Lock Key is not detected and when I hit OK, it pops up with a Login with the Country filled in with Republic of Korea, ID and Password are left empty. I don't know what to do from there.
Enter into download mode by turning off your phone, then hold vol + and plug it to your computer.
Download the official firmware for your device.
Download FlashTool.1.0.54
unzip FlashTool.1.0.54, open the folder and launch UpTestEX.exe
Select type:3GQCT
Phone mode: DIAG
Select kdz file: browse for your official firmware
Then click: normal web upgrade test
Then click: Upgrade start
a new window will show, chose english language. Country: korea, then click ok and wait untill the firmware installs.
Good luck.

ADB sideload
Need help to unbrick my LG G Flex F340L software version f340l20b. It was rooted using towelroot. later I installed SuperSu app. But due to this OTA update was not installing. once downloaded during installi it was giving an error like "Your device is suspected in rooting. System update is not available for rooted device".
Later I installed flashify app from play store and tried flashing CWM recovery. Once recovery installed, phone tried to reboot to recovery where I got Secure booting error message. But the most terrible thing happened immediately after that. During that time OTA update downloaded once again and started installing. immediately after reboot, my phone is stuck in below screen. Now that its almost 3 days, my phone is in the same state. Even if I connect it to PC, though it seems that the phone is switched off, in PC I can see quite a few disk drives prompting for formatting those.

Thanks for sharing similar experience in a different thread. I installed CWM in my LG G Flex f340l20b. Once after that, while OTA update getting installed, my phone gets into this situation where there is no download/recovery mode, only LG logo comes in the screen along with security error. phone is getting detected as qhsusb_bulk and getting too many disk drives asking me to format those.

Do you have tot or kdz file?
You can extract these file from kdz or tot.
Only 10 files are needed

Thats method is too clear.
1) U need 10 files aboot, boot, laf ,dbi ,sbl1, rpm, tz modem, recovery, misc.
U can extract these file from tot or kdz using lg firmaware extractor.
Note....kdz doesnt have misc file and it doesnt matter so dont worry
2) you need to install qualcomm driver and if yellow mark then disable digital signature enforcemt.
3) copy these file to unbrick very partiton tool folder.
Note..
If u extract these file from kdz or tot then these file files will be in .bin format then you need to simply rename the extension from.bin to .img
4)
See the disk managemet on your pc and find which disk no. Your phone showing.
If showing disk then run 1hardidsk.bat/exe
If it say disk2 then 2hardisk.bat
5)
Keep in mind.
D802 d800 d801 d805 d803 all have same partition table for these 10 files.
So if u dont see any model in the kist choose d800 or d802..
After its says continue close the window
And swithc off your phone by long pressing power button for more than 15 second so that phone turned off.
After turned off press and hold vol up button and conncet to pc.
If you stuck in download mode screen and didn't get firmware update screen
Then do this trick.
Switch off.
Press and hold vol up and connect to pc.
As u see download mode scree.
Keep pressing vol up many times
Around 30 times.

Yesterday a LG L Fino was brought to me for repair.It makes an error on boot.The error is the boot certificate verify error.I cannot fix this!
I tried booting in recovery,gives me the boot screen,then the error,black screen.
I tried download mode,same.
I even tried flashing it,but LG Flash Tool does not recognize it.When i connect the phone a whole alphabet of drives would appear with LG Logos on them.I was able to only open one of them,the size was 64MB and it stored a image folder.Device manager recognizes the phone as QHSUSB_BULK and a ton of Unknown Devices would appear,after that they disappear and the phone will be recognized as LGE AndroidNet USB Serial Port(COM4).Thank you :angel:

Hello sir!
I have never flash the phone. The first problem that I have seen was after one restart, it won't boot the os, I have seen the LG logo and after that it keeps reboots again. I have entered in recovery mode and wipe all data, but it didn't help. After that I started to see the message above(error) and that's all. My battery is completely empty and cannot charge it because the phone doesn't charge.

Hey there did you use advanced wipe to clear your data or was it factory reset.
If the LG Logo shows up and then the error comes then you can enter download mode by switching off the phone and then hold volume up key and at the same time insert a usb. You would enter download mode. If you enter the mode you can flash a KDZ

Or If you want custom rom only,enter into recovery mode.
Then click wipe and then advanced wipe.
Check data
Check System
Check Dalvik/art
Check Cache.
And then Press install and download the suitable rom for you phone.
If you cannot resolve the problem contact me again

No, they didn't use advanced wipe because they don't have a custom recovery installed. If you read their post more carefully, you'll see where they said that they never flashed the device, this means they have stock recovery, not custom recovery. None of what you posted helps them.

Hey there thank for informing me.
He can still enter into download mode and flash kdz using flash tool
Custom Rom cannot be flashed
But a stock rom can be flashed and can be fixed.
Its a soft brick so he can surely flash a stock rom and recover his phone :fingers-crossed:\
When you try to charge your phone it doesn't show the charging status
But when you completely drain your battery to 0% it will show 0% and shows charging and you can confirm that it is charging

Did you try to flash a stock update using TWRP?
If so, that is the problem. Stock updates can't be applied to a rooted device or a device that has TWRP installed, any one or both of these will interfere with applying the update. You can only apply stock updates to devices that have an unmodified system partition(no root, no Xposed) and have stock recovery, stock recovery is required for applying stock updates.
If this is what you did, your only option to fix this is to flash your full stock firmware. Do a Google search for:
"Return to stock (your model number)"
If the tools and files exist for your device, that should find it.
