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?

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

Hi all:
I am a blind. My device is Verizon LG G3. Android version is 11c. I want to realize device test mode, so I call ##228378 then press call button to enter services menu. Then I click the first option. A dialog appears and ask me to restart the phone. I don't know talkback cannot run at all. I press OK. Then I cannot do anything. I cannot hear any sound. I find a friend to help me to quit the mode. But she don't know how to do. I search in the internet, I know that if pressing power button then power off menu could quit this mode. My phone is restarted normally. But I find a new quesstion: my USB test mode is unavailable. I cannot use adb to control my phone. I find a rom flash tool to refresh the rom to solve this problem. But this tool cannot find any devices. My phone is seemed not to be connected into the computer. I want to update my system and root the phone. I can transport files into my phone. So USB cable is no problem. I also test the phone in many computers. Please help me. Thanks!
do'nt worry
you unstall all driver lg in pc of you
and restar pc
and install driver again

Hi: I have installed the drivers more times. It is no effert at all. And I also cannot share my internet through the USB. Do you have another solution? Thanks!

However, could you offer a download link of the drivers? Although I have made more experiment, I still want to try your way.
Please note: The option"broadband" appears from USB mode selection of notificationBar don't appears, so I cannot share the internet through USB, and is not that cannot get any effert from the PC.
Thanks!
if you online send id and pas teamveiwer i connect see driver detect
If do I just login teamviewer on my computer? What time do you want? I think I should after a good 8 hours. Thanks a lot.
Has anyone gotten their computer find their G4 through cmd (adb devices). I cant get the adb message on my phone to allow access to my computer. I turned on and off usb debugging several times but i still don't see the message on my phone to allow access. I let me computer download the drivers when plugging up my G4 as well as allowing the install of PC drivers.
yes, working great for me. Do u have updated and right drivers? u find tread here with right drivers..
Sent from my unlocked and rooted LG-H815
I was having the same problem..
You need to install the LG Drivers and then your phone will connect via adb..you will be asked on your phone to allow the port connection after installing the proper LG drivers. Verify and you will be good to go..
I used these ones below in the attatchment or you can grab them from.....
http://www.theandroidsoul.com/download-lg-g4-driver-for-windows-and-mac-mtp-adb-download-mode-77723/
I think I found the issue. I had Note 3, 4, Nexus 6, S6 edge, and G4 all still on my computer in the device manager. I uninstalled all of them plus I uninstalled the adb driver in device manager. Plugged my G4 back in and ran the PC driver update via G4 and it worked. I can now see my G4. Don't know if I had to do all that to get it working but hey it worked for me.
I was having issues with this myself and didn't find a solution. I found out that I was having better luck switching it to Camera PTP from the notification dropdown. Sometimes I have to toggle to MTP back to PTP, The dev notifcation should appear when it is actually connected.
1. PTP
(1a. switch to MTP back to PTP if it doesn't work)
2. 'adb kill-server'
3. 'adb devices'
-If you see your device, you can try to 'adb connect **IP**' but it will most likely say it was unable to connect
4. give it your adb commands you want
It's the only way I've been able to get adb, hope this helps!
I was having this issue also. After install win10 then adb connection to my LG G4 (h818) was not detected. Back to android.com, it said that if general USB driver doesn't work then we must find OEM driver to the producer web. LG ADB Driver was about 17MB. After installed the driver then it was immediately detected. Thank God, finally.
I have silly problem. I bought used G4 LG from someone found in online forum. Checked all series on phone (sticker), on software "about phone" all showing LG H815 software version H81510H, but by adb ( linux machine ) showed H812xxxxxx .... set on developer option debugging the command "adb reboot bootloader" just send device into android boot ( device boot ). I wish to unlock the bootloader and put CM. Hard button option > pushing vol up + power button simultaneously did nothing, vol up + power button then > connect to PC via usb, did nothing ( just send phone to device boot ) ..... I have no windows machine
Does anyone make this sw working on our LG G4(H815-international version)? Although I'm rooted, ADB debugging allowed...no luck. I tryied even mobizen's "booster mode". Did anyone managed to make it working? Great sw though-I use it with SG4.
I'm not rooted. I can get USB to connect (after I install the LG drivers) but it won't let me control the screen. Only lets me control screen on WIFI.
---------- Post added at 12:18 PM ---------- Previous post was at 12:04 PM ----------
Ok so i got it working.. Be sure to install the WIFI Install that Mobizen asks you to during setup if you didn't install it you can un/reinstall Mobizen and it will prompt you again, or you can download the LG Plugin v1.0 form the Play Store - search for Rsupport and look for LG Plugin v1.0. The thing that you probably are not doing is installing the actual LG drivers (at least that's what I was not doing). When you connect your phone and it has the notification to tap for more usb options. clikc that and a popup should come up asking you to Install PC drivers.... Click install and your phone will make the Windows disconnect sound and after a moment, and it will install a CD drive on your computer go to that CD drive and run the program called LG PC Programs. After that it should install drivers and you should be good to use Mobizen thru USB. Let me know if you have any problems.. i wrote this up on a quick break from work so it may not make sense.
somehow miraclously I managed to make it working w/o reboot. I had to close both apps(PC & Android), then I run Andr. app, "turned on booster"(although no notif. that booster mode is enabled appeared), then run PC app and at very end connected thru cable. And it worked (I tryied several times)
One plus 9pr complete brick. Cannot access fastboot or recovery. Will not turn on and when I plug in only shows a connect a chargwer screen. It is charged. I cannot get msm tool to connect either.
What led up to this point?
We'll need more info than this:
Are you using a Windows computer?
Is it Windows 10?
Have you plugged in USB via USB port on the computer or USB hub? (Should always plug directly into the computer)
Windows 10 has driver signature checks on by default, the Qualcomm drivers are not signed so you need to disable signing before trying to use MSM tool : https://www.tenforums.com/tutorials...river-signature-enforcement-windows-10-a.html (I usually use option 2, BCDEdit)
Here's the Qualcomm EDL drivers : https://www.androidfilehost.com/?fid=14943124697586335873
You need to press both VOL buttons and POWER to get into EDL mode, make sure you choose the correct assignment from the top "TARGET" dropdown in the MSM tool too and make sure it's the correct MSM tool for your region/phone. They're all available from here
There's a decent guide here
There's a video here for OnePlus 8/8 Pro but it's the same technique (remember to give him a like if he helps you out ) :
If the MSM tool doesn't show "CONNECTED" on any COM port then keep the cable connected and try rebooting the phone back into EDL mode again, it will eventually show up.
