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.

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?

Hey, i have the same problem, and i also can' t fix it, i tried all ways, but my pc dont detect my phone... so i hope that someone will find a way how to fix it... but it' s not normal what is happening with this phone...
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

3.Take your phone,get the battery out,then hold vol+ and vol- at the same time and plug in USB cable
4.Then you should see cheesy color screen(emergency mode)
5.Put the battery in
6.Open KDZ updater,put Type:3GQCT PhoneMode:Emergency
7.Browse downloaded software in your PC (V10C)
8.Hit ,,Launch software update"

Maybe your phone was damage. Did you recently bought that phone? If yes, then the concern maybe is the device itself.
But try install the latest driver for LU6200 [Make sure to download it in LG Mobile Korea] and maybe it would help. Make sure the computer is detecting your phone as you connect it.
Hope this will help you.

Yes Its Not Only Detecting but i Also Put my Phone On Download Mode (Pressing Power+Vol Down) and Flashed Successfully Engineer ICS KDZ File ,The Whole Process Was Done with No Error
But Still Same Mass Storage Problem.........
mass storage is disabled in ics engineer version.
you can try to enable it with adb: "adb shell /system/bin/sdutil ums enable"
or if it doesnt work, use an android software manager like mobilego to access your mass storage.
Thnksss But.....

To enable USB debugging, go to settings>about phone>tap on the build number 7 times. It will tell you "you are now a developer" and your will have USB debugging back
As far as your driver issues go, it sounds like you only installed fastboot drivers and not the regular drivers. Or somehow the regular drivers got deleted. If it was me, I would try rebooting my computer and phone. If that doesn't work, run the driver setup wizard in the Galaxy Nexus Toolkit. The first part of that process is deleting old drivers. It does a very thorough walkthrough on how to do that.

Try connecting your GNex to PC while in recovery mode then use ADB to push any ROM from PC to your /sdcard/ of your GNex in order to flash it.
At worst case, I think you can use a fastboot image to flash your GNex via fastboot.

Now i running nothing, pratically i formatted all internal data because i would use the 4.2.1 version that is on my pc, after the format the computer does not recognize my cellular phone, so atm i don't have any rom on my phone and now i don't know how i can solve that, it could be easy if i can browse the phone on computer

Hello Everyone,
my LG G4 bricked after I returned to stock via flash tool. It's not booting but I can access download mode yet theres a totally different problem: my pc won't recognise my phone, it doesn't appear in the device manager. I tried about 4 different drivers and every usb port.
Any Ideas?
Thanks,
Philipp
Edit: ADB doesn't reconise it either, same with fastboot

Did you try to downgrade? Try installing drivers on some other PC with different data cable, it should be detected.

Did you try to connect in download mode and flash stock firmware with the official toolkit? I don't remember it's name though

Yes of course but the pc diden't recognise the phone and it say its " not cot connected"
You need to install device drivers and ADB drivers before trying. Use USB 2.0 ports too, it's acting wired with 3.0 ones
