Hey guys,
I have an LG G3 - D855 phone .. on Stock Marshmallow 6.0 .. and it IS working fine ..
The thing is i want to return to Lollipop, so i decided to use LG Flash Tool to reset the phone to its original state
I Press volume up while the phone is off, then connect it to USB .. it goes into download mode ... but in Device Manager it shows ONLY ONE port " LGE Androidnet usb serial port " .. and of course i'm unable to use LG Flash Tool
I exit download mode .. turn on the phone ... connect USB .. ONLY THEN that i can see "LGE Mobile USB Serial Port" .. i mean it shows ONLY When the phone is ON
I've tried so many Drivers ... even the latest one .. on LG site " LGMobileDriver_WHQL_Ver_4.1.1 " .. Yet no result ..
Is there anyway to fix that ?!
Have a nice day!
@tute123456
Have you tried changing the com port to 41 while in download mode.
You rom file it is .tot or .kdz ??

unnistall drivers, restart your pc and install drivers again, change usb port, download Last drivers from official website of LG

So I used ROMmanager to get clockwork recovery mode. Now when my phone entered the recovery mode it just say:
"Fastboot mode started"
"udc_start()"
If i connect my USB cable to it it says --suspend--
Now i tried using KDZ_FW_UPD in Emergency mode to restore original firmware but it cant find the phone. The log is:
[R&D Test Tools Log File]
10:50:59 : Launching SW update
10:50:59 : Unpacking KDZ
10:51:14 : KDZ file extraced
10:51:17 : Files were extracted.
10:51:17 : LGMobileDL Load.
10:51:17 : Port = -1
10:51:17 : Connecting to phone
10:51:17 : PHONE WAS NOT FOUND!
10:51:19 : ===FINISHED===
I tried this procedure on 2 pcs but no luck. It seems that my phone can't connect to PC with usb cable.
I installed LG Moblie United drivers and disabled the lg modem thing in device manager. I am using Windows xp Proffesional SP3.
So does anyone has any clue what I am doing wrong ? If u need more info just ask.
Maybe if I try from some linux distro it will detect my phone ? But what tools to use then ?
Use fastboot to recover the phone. Check the wiki at the Troubleshooting section.
---------- Post added at 03:31 PM ---------- Previous post was at 03:12 PM ----------
I recommend using drivers latest version. Last time I checked, United Mobile Driver was version 3.7.2 release 4.9.8.1 and Modem Link Driver was 1.0. I'm providing links for download from my personal Dropbox folder because I don't remember from which LG site I downloaded them from.

i had the same problem few days back... (ROM Manager sucks).... ok.. so.. before connecting the phone to the PC.. remove the battery, press both the volume keys (no need to press the power button)... and connect the usb.. now the cell phone will be in emergency mode.. try launching the software with kdz updater now... it should detect it.. after its detected.. connect back the battery (without disconnecting the USb cord ofcourse)... hope this works.. good luck
Good tip, adding to wiki later...

Didn't I said i did that ? My PC wont recognize my phone in fastboot or emergency mode, with fastboot being stuck at udc_start() and when i connect USB it says "-- suspend --" ,
I tried this guide madmanzrocks still dont see phone.
deleted lg modem, reinstalled all usb hubs, tried 10 versions of LGunited drivers, used both official update tool and kdz nothing works(can't detect phone), and also tried from cmd.
My problem isn't how to unbrick but rather why my pc won't recognize my phone :/
So, no feedback (USB Device connected sound) when conneting the phone? I assume you have tried all ports available.... Long shot, but maybe the phone's USB connector is dead... You have some background on electronics? If so, you can follow the service manual I reposted recently at the General section to check if the connector is gone (p. 113).

yeah tried all ports, I¨ll try on several other pc's. no connection sound, but phone is charging. I have quite some background on electronics so ill check it out when i try this on couple others pc's. Don't want to dissaemble it quite yet and if it rly is dead repair will probably take more money then i spent to buy it(I got it 2nd hand for around 50 $). It happened before that my PC coudn't recognize some devices but never like this. I ussualy get device not recognized, malfuctioned or smthing like that .

as I mentioned the same problem was solved bu connecting the cell phone with the battery removed. But if even that doesnt works for you, then maybe there is a fault in your PC. Does your PC instantly recognizes USB Pendrives? And which OS are you using?

Don't know if it helps or you already tried it.
Start fastboot v2 and start the flash so it waiting for device.
Then plug in usb and start phone in fastboot.
That worked for me before.

I can try.
First start fastboot v2 on your computer.
Load the recoveryimage amonra or cwm5 (not cwm6)
Start flash so it say searching for device.(or something like that)
Plug in usb in computer.
Start your phone in fastboot.
Plug in usb in phone.
If that don't work you can try to instead of start phone first start it with usb cable.
Can need to unplug usb and plug it in a few times if the device say suspend.
Hope it helps.

Can you please add the links to this files or the files? I would be very thanksful...
Up to this point i tried all the methods you guys told me and some i found myself. Nothing worked for me as my PC stil won't recognize my phone, I have also tried all this methods on 4 PCs(2 had windows XP Proffesional SP3 with all the updates, and 2 had Windows 7 SP1 with all the current updates installed(note that 1 version was 32-bit and other was 64-bit).
My conclusion is that the USB connector is DEAD, even thought i can still charge my phone trough it. I probably won't be trying to fix this anymore as I've found an 4th gen iPod and i'll be using that from now on.It is true that i can't make calls(at least not the standard way, you know, it doesn't support SIM cards), but i have my old dumbphone phone for that and this will be used for just about anything else.
So thanks to all of you guys that tried to help me but i fear this is unrepairable. If anyone want's this phone I'll give it to you for free so you can have some fun cracking your head to see what is wrong . I only ask that if you find a way to fix it you post it here and notify me about it(send me pm).Otherwise do whatever you with it.
I have solution

I got it working in Windows 7. I'm having issues with Windows 8.1.
For Windows 7, download the drivers that I mentioned above and restart your PC. (Make sure your phone is not plugged in while you are installing the driver)
After your PC is fully loaded, plug your phone and that should do it. If it doesn't work then add the path to the driver in the ENVIRONMENT VARIABLES.
Just install LG PC Suite and do the update option under help then connect via USB and if it cannot find it, it'll ask if you want to re-install the USB drivers, do so and it'll work.
I've done the above on 8.1 and had no issues.
people still use a USB cable to connect their phones in 2014?
there are so many wireless solutions that work perfectly, why bother with USB cables?
I too am having the same issue. I have tried installing just the drivers and then installing LG PC suite. I have the same exact 3 devices listed:
CDC Serial
LGE Android Phone
LGE Android Phone
I also am on windows 8.1 update 1 (64 bit) and am very desperate to get this working so I can root my device. Any help would greatly be appreciated!

Hi, use flashtool.
Put the dll and tot file, you must change the number of the serial port to 41 in advanced setting of this port.
When flashtool reconize the G3 press start and wait.

If PC doesn't recognize your device as Qualcomm HS-USB QDLoader 9008, you need to JTAG your device, or short pin.
