Hi
I have a t-mobile D851 LG G3, for which i was trying to restore to STOCK software, through one of the guides elsewhere on the forum. My first try FAILED, and now the phone is stuck on the "FIRMWARE UPDATE - Do not unplug the USB connection until the process is finished - USER B51" screen
No matter what i do (all key combinations for recovery mode, download mode), plugging, unplugging the phone, taking the battery out for 30 mins or so, and putting it back - NOTHING is working. It all goes back to the screen mentioned above.
I tried running the LG Flash tool again, but it fails.
Any ideas? Any help would be greatly appreciated. This phone is my daily driver, and I am in a major fix without it.
link for the guide I used to flash

EDITED: LINK HERE
http://forum.xda-developers.com/tmobile-lg-g3/general/firmware-t-mobile-lg-g3-t2818667
EDIT - SOLVED
Thanks to everyone who chipped but especially to pside15 and one other person (but i can't find his post)
The solution was very simple - I was making the idiotic mistake of looking at just the computer screen and NOT the phone screen. The computer kept giving me all sorts of errors saying 'update failed - can't connect to server, yada yada' etc. I just left the phone alone - came back 10 mins later to working phone.
Moral of the story - Watch BOTH the phone screen and the computer while doing these things, because my computer had me believe that this is not gonna work - the phone obviously disagreed
When the flashtool fails, whats the error? Its not hardbricked if it still comes on and goes into download mode. Look at THIS image and see if you set action mode the same. This one mistake caused me a headache last night for 6 hours.
Your link doesn't work.
I use this LG Flashtool when I soft-bricked my G3.

it doesn't come into download mode - its just stuck at the 'firmware update' mode at 0%
And does it matter that its a D851 (the t-mobile) version?

The computer does recognize it. But when it comes to the point of verifying connection between phone and LG software update tool, it fails saying 'make sure the phone is connected to the computer, etc'

Uninstall drivers from device manager in computer, reinstall. Make sure to change com port to 41. Also board dl in action mode is a complete overhaul of firmware, the other setting in action mode is to update firmware.

If your phone can turn on an go into download mode you can flash it. Just try w different computers
Same thing happened to me

Im not 100% sure, because I have the Sprint LS990. As far as the model # goes, it has to be the exact one, which should be under your battery. I'll look into it more in a few hours when I get off work. Try HERE for tots and dlls

LG G3 D855 - Firmware upgrade
Hi,
I am in the same situation here. I have used the following tutorial and successfully flashed the firmware
I am not allowed to add the link yet.. Sorry
Type the following on YouTube
How to Unroot/Unbrick LG G3!
My Phone was up and running and I forgot to close the LG Flash tool on my PC. The flash tool started to flash my phone again, at about 80%, when the tool restart the phone , it never came back and since then I am sitting at the firmware upgrade screen.
I can see a yellow mark in device manager under Portable device.... I can see under port LG Mobile Serial port which i set it to 41. I read about something called wipe cache partition. I have used few different PC but it is not downloading the firmware at all.......... Please help!!!!!!! Can I use Linux ADB to flash the firmware .... Any tutorial ......
I'm posting a question as I've spent days searching with no luck.
I have an LG G3 that while in normal use got very hot and turned off. Now it gets stuck at the LG logo and doesn't boot. I tried a normal factory reset but this just goes back to the LG logo and nothing happens.
So I'm trying to get into the download mode "Firmware Upgrade" screen to flash the stock rom. I hold down volume Up, and plug in the USB and it gets to the little "Download Mode" icon but does not continue to "Firmware Upgrade" and the computer (I've tried 3 different systems) wont recognize the phone.
Interestingly at some point while being in download mode it switched to fastboot, I have no idea how this happened but I was able to run commands on the phone using fastboot.exe, however I have not been able to get back to fastboot since.
Also I'd really like to be able to recover the data on the phone.
Any help would be appreciated.

Thanks I tried the drivers you've provided but still no luck. The computer won't detect the phone at all, it doesn't attempt to install drivers nor does the phone show up as a generic device.

I hope not, this phone was purchased in Media Markt in Germany and it's not covered by warranty here. LG Australia said it would cost up to $260 for them to fix it and the phone could possibly be downgraded if the mainboard needs to be replaced. I don't know if it would be possible to claim the German warranty.

So today I tried flashing android 5.0 on my T-mobile LG G3 D851. I put it into download mode, started the flash and waited. My LG flash tool then crashed and closed. My phone was %6 through the installation however and was just left frozen after it crashed. I tried every way possible to restart it and get out of the screen while keeping it plugged in, but I couldn't...so I took out the battery and put it back in. Now nothing is turning on, I can't put it in download mode and the charging LED doesn't light up, etc. It's completely bricked....what do I do? I've already tried taking out the battery and waiting and plugging in the cord and then battery. Please help! I can't afford the insurance or another phone...
EDIT: Also the battery does have charge...although I don't know how long it will last.
EDIT 2: I just realized this flash was for the 855 variant..not 851. Does this mean that I am just screwed?
It means that you got expensive brick.
You cant enter into download mode or recovery?
Probably only help is jtag. Find someone who can do that.
Sounds like someone has learned a very expensive lesson! Have you tried to factory reset it?
Yeah JTAG is all you got if no download mode

The linked solution works only if the device shows some signs of life - atleast a boot logo.
i have a D851 that a friend bricked. She tried upgrading to Lollipop and flashed the AT&T baseband on this TMobile version. The result is a hard bricked device which does not even seem to power on. Shows no signs of life, except when connected to a windows pc. It shows up as 'LG Androidnet USB modem' in the device manager. No boot logo, recovery, or download mode. Fortunately she has IMEI and twrp backups for this phone (boot, efs1, efs2, radio, rpm, tz). I did some research on JTag solutions. Unfortunately, none of the boxes support the D851, yet.
Any ideas on how to recover this device would be greatly appreciated.

I was trying to put TWRP on my G3 (D855) but it failed for some reason but the stock recovery was deleted. So there was no recovery in phone. I gave it to a friend to try putting TWRP in it, he also failed and somehow corrupted the partition. He said the phone is completely bricked now and is not even turning on.
Any suggestions what I should do?
Too few details provided.
Can you enter download mode?

I noticed one thing. Even though on the cover it says D855, but when I opened the phone, on the mother board I saw D851. What does this mean?
The motherboard should be right, its tmobile. Did you have fm radio on it? If not then tmobile for sure

Hi everyone
I having this problem with my lg g3 d855 ... My phone was at 5% then i wanted to remove kingroot because i wanted to flash super su. After uninstalling kingroot (in the app) the app crashed ant after few seconds my phone turned off... i was thinking my phones battery just died, but i was wrong. My phone wont turn on now :/... Only response i get from it then i plug it in the charger without battery (it show no battery error)... then i put battery in, screen goes blank.
And also i installed twrp using app from store (Forgot the name, but for d855 model)
*LG G3 D855 Android 6.0 official* (if needed.)
i tried:
holding power button for 15sec without battery and then charging it... Didn't work :/.
Putting another battery (Galaxy s3... Charged to 30% at least. I don't have another lg battery ), same result.
New battery also doesn't do anything...

I was in the middle of unbrick my g3 from hard brick to soft brick. I flash firmware using lg up at 99% then the phone died as it tried to reboot. It won't boot at all. As you said when remove the battery and connect charger, i can see my motherboard working with exclamation mark. As soon as i put the battery, motherboard out and no sign of life. Is this sign of bad battery or what. I don't have spared battery
I recommend first, to users with similar problems, to try first my guide in following link and after the pins in motherboard-tot files

I have D858HK hard bricked for 2 month and i use v10d to flash every partition. Then it won't boot into recovery. When i use v985 .tot, it successfully boot into recovery. Also on LG Smart Board diagnostic, my model not detected. Even if i manually select, nothing happen when it reboot. Right now, i have no idea whats wrong as i spent countless of hour on google and XDA.
