Hi folks,
I want to restor my LG G3 D851 phone to stock using lg flash tool to kdz/tot but i can't because my computer is not registering my device while in download mode (new device connection does not pop up, like if the device wasn't connected to the PC). Also, there is no sign of the device under device manager, so i don't know what to do. Any help is highly appreciated. I already tested with different driver versions and different cables with no luck.
Please, somebody help me!
Same issue

Hi, OI am having exactly the same problem. I've done it dozens of times. In my LG G3, and in many other phones. But suddenly, after a factory reset, my international LG G3 refuses to connect to my PC, both in download mode and when it´s on. No sound from the PC. Anyone any ideas? Thanks

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.

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.

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

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've got an LG G3 by US Cellular (US990) that I'm trying to downgrade using LG Flash Tool. The problem is that it's not being recognized by Flash Tool or by LG PC Suite for some reason. When I plug it in in normal Android it recognizes it whether it be charging, MTP or PTP. But when I go into download mode these programs do not recognize it and so I can't flash anything. Anyone had any similar problems or anything I can try? I have installed the drivers multiple times and I'm on Windows 7 64 bit. Any help or suggestions are greatly appreciated, thanks!

What does it say when you plug it into the computer?
QHUSB_BULK?
I guess the better option is to try using LG flash tool to flash kdz, not sure if download mode will be booted since you mentioned download mode failed.
If none really work then should consider restoring stock rom using LG pc suite
Am I correct in saying the phone simply does not boot into download mode? You have have the phone off, hold + or - and plug USB in?

asking for help
Hello!
I would like to ask you, that can you maybe help me with my LG G3 (D855) (16GB). I live in Europa, Hungary
I bought the device as used, and i would have liked to download the latest software via wifi, then on the phone restarted, and was only the TWRP on the phone, i restarted the device again, but i could entry only in the TWRP. I downloaded a ROM from the XDA, and i made a mistake, i installed the D851 software. The phone is bricked, no download mode. I tryed to unbrick, but every method need the download mode. If i put the device on the PC, the PC see only as modem. LGE AnroidNet USB modem, and the the port name LGE AnroidNet USB Serial Port Com4. If the battery is low, i see on the display, that show that need to charge, but nothing more life signal. If you can help me with some information and with files or via teamviewer, i will glad for you, and also donate. i think i have the correct TOT file, and the DLL file.
LGD855AT-00-V10k-234-30-VUK-SEP-03-2014-16G+0.tot
LGD855_20140526_LGFLASHv160.dll
I downloaded a program "BoardDiag3.99c.zip". but this program ask the BIN file, i found another program b2b.exe, that ask the TOT file at the extraction. Maybe that's is same?
As i wrote the PC sees my phone only as modem, and LGE AnroidNet USB Serial Port Com4. I dont know what is "Qualcomm HS-USB QDLoader 9008 mode", i dont see in the port menu. I hope that You, or someone can help me. i downloaded the QDLoader HS-USB Driver, but again show only the "LGE AnroidNet USB Serial Port Com4" (or now this is com41, i wanted to try a method, but need the download mode) Sorry for the bad english.
Have a nice day!
i have the same issue

Please give a step by step tutorial since l cant seem to figure out how you solved the issue
Hello so I am hoping i could get some help fixing my lg g3. Its been stuck in boot loop for a couple of days now and I've looked and searched and I cant seem to fix the problem. I don't know if its hard bricked or maybe there's a way to fix it. The issues all started when i couldn't connect to wifi or use Bluetooth on my phone. At the time i tried updating to 5.1 but was not available yet. I had seen on some threads that by downgrading it might fix the issue. So I downgraded my phone by using LG flash tool. I downloaded the dll. at&t D850 file and the at&t D850 tot file. Afterwards the wifi and Bluetooth was fixed. But then it started to reboot on its own and the issues came back. Although after a couple of reboots it just got stuck.
I've tried doing the factory reset by holding the volume down and holding the power button and i see the android logo but it s till gets stuck on boot loop.
I've also tried reinstalling kitkat with LG flash tool and when i do it says Fail Mino OS at around 90%.
I was also gonna try and use Odin3 which i read might fix it but when i connect my phone to my pc it doesnt recognize that its connected. I uninstalled and reinstalled the lg drivers but still cant recognize it.
If anybody could help me and give me some advice that would be greatly appreciated
Same problem here, did you fix it?
I got exact same problem, don't know how to fix it.
Possible solution (if u downgrade mm to kk and the result is boot loop)

Can you put your phone into download mode? => Hold volume down button for a few seconds and attached the usb cable to your phone?
Also, how old is your phone? LG phones have a history of having issues with batteries dying and this causes the phone to constantly reboot. I had this problem myself, which is why I know about it..
hello,
after installing twrp in my lg g3 d856 i cant able to on my cell. no recovery no download mode no boot , nothing at all. i guess my cell is hard bricked and in PC device manager when i connect my cell it shows LGE androidnet usb serial port. cant find any solution . can any one help me on this please. m using LG D856 Lollipop and PC runs on Windows 10. please i need help
If you are absolutely sure that none of this works. you can try a solution that saved my phone from going to recycle. It takes a serious amount of trying, technical knowledge and tools. If you want to go ahead, make sure there is nothing else you can do!
Yes i am sure its hard brick..what procedure u suggest
