I tried to upgrade my rom but the process crashed. The utility mtty doesn't work because when I connect the universal, boatloader mode by the cable, to the pc, it says "USB not recognized" (sometimes when I connect the computer is frozen till I disconnect the cable of the universal)
Please, I tried to have some solutions in the forum but all the posts indicates is needed previously the usb connection.
Do you know if should be possible to run the flash of the rom in other way, for example using a serial cable connected into the miniusb of the universal, because the boatloader screen says "Serie, v.1.01"
I apprecite what you can say please, I'm really in a hole.
Try this...
Try taking out the battery for a few minutes (10-30mins) and reboot your PC then repeat upgrade process. Hope that helps. Good luck!!!
I have the same problem on my PC at work, it's caused by a poor USB chipset in the PC, or trying to connect through a USB hub.
The only thing I found that worked was to try a different PC, then it was fine...

In my case it still happening in other computers. Conclussion: some piece of the software in the universal has been lost. The screen shows "Serial" that means on some way that is opened to comunication but not USB.
My questions are:
- should be possible to put some starting software in SD and do the universal boot on it.
- do you know how to connect to the computer COM! port from the usb miniport of the Universal.
I appreciate, I was not planning to replace now the Universal...

Now works.... I still thinking windows is so stupid software made for distroy our mind ....
Solved after install drivers for a converter usb -rs232 ( I was looking for the way to connect from rs232 the universal)
I'm happy again and I promise don't try to change rom again (at least for a while)
If some person is interested in what brand of software/hardware I installed, send me a mail...
Thanks hearing me ...

i have the same problem with my friend's uni
does it mean that you don't have to own any adapter, just have to install drivers for USB to RS232 adapter
if yes, where to find it?
thanx

I want to say that is running after doing some things and obviously some of it solved my problems. I made:
- unistall last version of activesync and go back to version 4.0
- delete all the applications using ports usb.
due the connection still not running (windows message: device not recognized) and because in the screen of universal I saw: "COMM1" I tried to connect from computer port rs232. By that I purchased some special cable, name: hama brand, rs232 serial, 9 pin - usb.
As you can imagine all the steps I followed were followed by the typical restart of windows. In this sense is important to say that the universal, after connect, need to do a soft reset each time (again windows....)
Other comment is that I unmark the option to connect by usb in activesync and mark the connection by com1.
and after all was done, connecting by usb the unniversal, kill wcescomm, windows said "NEw usb device, sync device". I started mtty and now appears the USB option, great! same time the screen in universal changed from comm1 to usb, more great....
and that's all.
does it mean you solve your problem using special USB 2 RS232 connector?
ZeD
PS: it was my first idea , but i still believe i can solve the problem using USB port

I think my english wording was not fine. I mean I solved my problem after install the sofware -drivers- of the rs232 connector, but connecting to the universal by usb as on standard way I was syncronizing previous the crack with activesync.
OK, where to get this driver?
thanx
?????????? NOTHING ?????????????

I have had the same problem several times now (search the forum for the thread).
I tried three different PC's/laptops and three different USB cables all with the same error as yourself.
Eventually I got a connection but the laborious process of trying - failing, restarting windows and soft resetting the phone, trying - failing........... until it finally worked. I did nothing differently the time that it worked but the strange thing is that it has worked every time since! Maybe the USB driver the phone has a bug in it that causes it to get 'stuck' in a mode where it will no longer correctly operate but once you have managed to 'kick' it into action it seems toi then carry on working.
It was also a ROM upgrade that caused my USB phone driver to stop functioning. Maybe the fact that the phone has a slightly diffferent software configuration after the upgrade but exactly the same hardware fingerprint causes the driver to fail.
Every time that I have had this problem it is after an upgrade but once I have gotten it to work once with the new ROM, it always continues to function - until the next upgrade.

If you're stuck in bootloader mode only, visit www.buzzdev.netand look for ExitBootloader utility written by the great Buzz. Just follow his instructions or scroll thru' Universal's forum here and there for problems relating to "stuck in bootloader"
hope this helps
no device is not recognized by PC so any trying to use exitbl is not available, anyway this option was one of the first what i have tried
thanx anyway
ZeD
i had the same problem with the QTEK of my principal after I upgraded his ROMs.
(after the hard reset, the pocket remained in bootloader mode).
you can solve this problem in a very simple way:
you have to launch the bootloader installation (BL1.01_RUU_UNI_V.1.2.EXE) from the PC (still connected with the PPC through USB) while the PPC is in bootloader mode (on your display you see "USB > Serial 1.01" or something like that).
then you do a SOFT reset and the pocket boot normally.
very simple.
i hope to be helpful to someone.

I had some problem. After uninstall all usb applications in the pc and install the software for cable usb -rs 232, doing some softreset in the pda connected, it turned the screen message "Com" by "Usb"
I'm hoping someone can help. I have an LG G3 D855 phone and is factory unlocked and running Lollipop 5.0. When I first got the phone (second hand), I was able to connect the phone via USB to my PC and was able to transfer files back and fore no problem. Until about 3 weeks ago, I am now unable to do this. The PC won't recognise the phone at all, all the USB connection does is charge the phone and I can see no option to get the phone to change to file transfer mode.
I had a look at Storage in the settings menu and I don't have the three dots that some people have spoke about. I have factory reset the phone and this hasn't fixed it.
I have tried using a different USB cable, this was the same. The drivers are installed (phone was recognized before). I have also tried the LG Suite, again same result. I also had a look in Device Manager for ACER something or other and this wasn't there.
I am currently having to use Bluetooth to transfer files back and fore to my PC and this is a bit slow. I'm assuming that an update LG have done has somehow broke the USB settings. I am also unable to root the phone (tried this before the USB stopped working and nothing worked) and possibly go back to KitKat 4.4.2 to even try that.
My phone has software version V20u-EUR-XX, Kernel Version 3.4.0 and build number LRX21R.A1439960697. There is no update available for my phone in the Software Update center.
After quite a bit of searching, it seems that this is a common issue but I have not found a solution to this. Can anyone help? Is there any firmware or software that I can try?
Thanks.
Assuming the OS is Win8/8.1 or Win10, have you already tried this?...

I couldn't tell you what the differences are between software revisions, only that 20u is newer. And I believe 20w is the latest available. I would probably try reinstalling the latest drivers from LG...
http://www.lg.com/us/support/software-firmware
... then again check to see if your PC recognizes the phone. If the "Charge phone--> Tap for more USB options" notification doesn't appear after installing the latest driverset, I'm not sure what else you could try. The LG Flash Tool needs to be able to communicate w/ the device when it's in Download Mode. You might be able to find something in the [Guide] LG G3 Stock Firmware (Go Back to Stock) KDZ & TOT Method thread related to the same problem you're having.

Just a quick update, can't even get the phone into download mode. I press volume up, insert the USB cable in to the PC and all I get is the battery charging icon. I'll have a further look this weekend - not good so far!
Thanks again for the replies and help.
Firmware W seems to be flashable only via TWRP or ClockWorkMod just now?
I have been able to get the phone into Download Mode a few times (not all of the time) and when I run LG Flash Tool, it just tells me that the phone isn't connected. I'm going to assume that the USB port is in someway defective. Can't think of anything else.
Have you tried w/ a different PC and/or OS? Have you tried connecting the phone via different USB ports (USB 2.0 compared to USB 3.0 or vice-versa)? And I assume you've already installed the latest driverset from LG?...
http://www.lg.com/us/support/software-firmware
Yes, I got into Download Mode once or twice on the laptop. I'm using LGMobileDriver_WHQL_Ver_4.0.3. I have tried USB 2 ports on both my Laptop & PC. I've tried driver 3.81 as well.
OK, got a new USB Charger port fitted just in case it was the port that was wrong and it's still exactly the same! I did a factory reset and have setup the phone for now. During the factory reset, it does pop up with Updating Android and has 169 updates. If anyone here has the LG G3 and has it working file transfer wise, can you tell me what version of the LG USB drivers you are using? Is it possible an LG update has caused this?
Thanks.
It's fixed!!! I think there was an update yesterday for Android Devices or Services, can't remember which was made available yesterday, installed that, reconnected the phone to the computer just a few minutes ago and it has finally been recognised! I can finally transfer files between the phone and the PC.
It was an LG update that has fixed this.
At last.
I'd like to say thank you for all the replies and help.
Hi Guys,
A weird one here for you, I'm already contemplating throwing my phone at a wall that's how long I've been trying to fix it.
I have a LG G3 D855 Gold 32gb model purchased via Kogan in Australia.
The unit is now on Android 5.0 (no updates available for 5.1+) - Software Version V20i-SEA-XX with Build number LRX21R.A1440645925.
This phone is non-rooted with stock ROM etc.
So the issue at hand, I upgraded my Win7 PC via the upgrade option to Win10 to retain my games/files etc.
Now when connecting the phone to the PC it only goes to charging mode and I am unable to click on it within the drop-down to change it to anything else.
I have tried LG G3 drivers, Googles generic drivers, ADB suite drivers. I am unable to adb find the phone, I do not have an Acer Composite device in Device Manager.
Win 10 keeps saying the device is not recognised/malfunctioned.
Tried different cords, double checked the connector on the phone for any dust specs etc.
My PC refuses to work with any driver I have thrown at it, however in each scenario with various drivers, warnings still persist in Device Manager.
Some of the drivers force the phone to connect/reconnect and cause the "ping" sound each time it disconnects and reconnects (with malfunction warning prompts).
This is on Win10 with 64bit Home edition.
I am at my wits end and can't think of anything I haven't tried beyond a factory reset of my phone (hoping not to at this stage as I'm thinking it's driver-related).
It won't let me tether or anything via USB also, same goes with USB debugging, no change.
Lastly which may also help narrow it down, with the phone plugged in BEFORE it gets to the OS, I can change between PTP/MTP and USB charge, however once the Win10 OS loads up, it disconnects/malfunctions and lists Charge Only.
And yes, this phone can connect on my Win7 small PC which I use for testing crap out on.
Any ideas guys?
Let me know if any log files or anything is required.
At this stage I am unable to do a root to the phone (due to adb issues etc) nor can I connect to the internal phone system unless I use in the in-built file explorer.
Edit: *SOLVED*
Ok so turns out the issue is, and this is just my case, my motherboard has various utilities, one of which is a USB 3.0 boost option.
When I did an upgrade to Windows 10, it somehow screwed up various programs on my PC including registry etc.
I reinstalled the particular utility (I was actually trying to fix my graphics clock etc so happy coincidence) which also re-installs the USB 3.0 Boost software which in turn has fixed my USB Ports.
So if you have a custom built PC (my Motherboard being a Rampage 4 Formula). Check the Mobo Utilities/Drivers for any conflicts.
I have the exact same problem, and I can't seem to find a solution for months now. It's really annoying and depressing

Using the drivers on that page you have advised gives the following.
Device Manager shows a Warning on it in USB controllers as "LGE Mobile USB Composite Device". It automatically "malfunctions" according to Windows 10 and I can't change the connection interface on the phone.
Going into the properties on that device in Device Manager lists the following;
This device cannot start. (Code 10)
A device which does not exist was specified.

I've had the same issue with my LG G3 in being unable to connect the device to my laptop. I'm not sure if the cause was a phone software update or the upgrade from Windows 8.1 to Windows 10. Either way, I searched and fixed it tonight by installing updated drivers. Hope this helps others as well.

Hi everyone, I bought an LG G3 Korean version (F400S) unlocked recently. It is a good phone but I am experiencing three annoying issues (out of the box) with the phone and they are:
1. NO sound at all from the back loudspeaker. The volume is set to maximum, there is no sound from music, video, notifications, touch sound effects, or even ringtone! Surprisingly, when I connect my earphones, there is sound in my earphone, when I remove the earphone, absolutely NO SOUND from the loudspeaker. The sound from ear speaker (the one used to make call) works. I have tested the ringtone in the Hidden Menu, when the ringtone is being played, there is no sound at all.
2. The LG G3 charges well when connected with the charger and when connected with my laptop as well. However, whenever I connect the LG G3 to my laptop, it only charges, it is NOT RECOGNIZED by my laptop. I have the LG Mobile driver installed (downloaded from the LG website (Korea website)), the LG PC Suite installed, the LG Mobile Phone Support Tool installed. Whatever I do, changes the USB cable/ USB port, try in different windows version (Windows 7, 8.1 and 10), USB debugging on and off, reinstall driver, reinstall driver from the option in LG PC Suite, restart the PC several times, NOTHING happens. It is not recognized at all in my laptop. ALSO I cannot see any thing related to LG driver in the Device Manager.
3. USB OTG does not work. I have tried with a working OTG cable to connect a pendrive in my LG G3, it is not recognized, even in the File Explorer of the phone. The cable and pendrive is however detected in my other android device.
The Android version of my LG G3 is Android 4.4.2 (I have received only one update for improving Google experience (about 10 MB).
The Kernel version is 3.4.0
The build number is KVT49L.F400S11a
Software version is F400S11a
Please help me, I have googled for the problems, searched in Youtube as well but no solutions. The phone was bought online, it is original but I have no warranty and even if i need to repair, I will have to send it back to China, which will be money and time consuming. Please help me.

Thanks for the reply, I tried your suggestion, but it did not work. Again, when I tried to connect the LG G3 to the PC so as to flash with the KDZ, it says on the taskbar: 'The last USB device you connected to this computer malfunctioned, and Windows does not recognize it'. In the Device Manager, I get USB Device Not Recognized (Error Code 43), Unknown USB device (Device Descriptor Request Failed) Error Code 43. I googled this issue as well no success, I reinstalled the LG Drivers, rebooted my PC, again NO LG DRIVERS in the Device Manager, and whenever I connect the LG G3 I get the same message I mentioned above. Hence, I cannot upgrade to the v20F version as I cannot connect the device to my PC.
UPDATE: I cannot put the device in download mode for flashing. I hold the volume up button while connecting the cable to the USB 2.0 port. The LG logo appears on the phone and it just charges. Also, I have tried to remove everything related to the drivers and reinstall, now I do not have the Error Code 43, BUT still the phone is not recognized.

Pull the battery
Only press the volume up button while connecting the cable to the USB port.
Let me know if that works. It sounds like your pressing the power button first, pressing volume up and then plugging the usb cable in
If it doesnt theres also the adb method as well that i can tell you after

First update your drivers on your computer. If that won't work try different ports. USB 2.0 or 3.0 can make a huge difference. Your speaker is probably dead. And i don't have any experience with USB OTG so I can't help you with that

Already tried that with the '15-sec ADB' something like that + with Android studio, I have searched on youtube and google how to do it, but nothing happen when I enter the command, it just says that device not found. Whenever I connect a pendrive or my other phones to my PC, I can see in device manager, it refreshes and the driver for that particular device appears. BUT there is NO refresh nor any driver appearing when connecting the LG G3. Today I tried it with my friend's USB cable (he has the LG G3 (D855), it does not detect as well in his PC but his phone is detected in his PC. I really do not know what is the matter :crying:

First update your drivers on your computer. If that won't work try different ports. USB 2.0 or 3.0 can make a huge difference. Your speaker is probably dead. And i don't have any experience with USB OTG so I can't help you with that

Thank you for your reply, I have already tried all of these, nothing is working.
Did you figure out how to get your phone recognized by the computer? I am facing the very same issue and I'm feeling hopeless

No, i am still having the same issue. I think with an update it will be okay (but I have not received any update till now! I am stuck with Kitkat 4.4.2). If it is a hardware problem I will have to return it or replace the USB port or motherboard.

Oh, OK thanks. I'm still reading forums in search for a definite solution.
Good luck!
Hello my friend
I cant understand the D855 while trying to connent it to my PC.
I have installed all the drivers and PC suite
When I connect it with the usb cable- its makes the desired sounds - seems that everything is ok!
even V green mark that the driver installed is shown.
But, the most important- I cant see the Drive shown when I open "my computer" on PC
Dont have access to folders and files.
I tried more then everything
Change to MTP
Debuuging mode
Change some usb cable
I already make a hard reset.
The main problem is with morelocal 2 language.
In order to make the app change a language- I must connect it to the PC.
So
what do you think the problem is ?
Is there any way to install another rom without connection to PC ?
Thank you so much

Well, I have kinda the same problem. My G3 isn`t recognizied by my pc or laptop in any way beside that sound it makes if you connect an usb device to it. It doesn`t shows up in the explorer or the device manager no mater how many times I install the drivers. I also tried to change the mode from MTP to PTP and anything else that is there. I resetted it a few times but nothing. Debugging mode also didn`t change anything. And of course I can`t flash a stock firmware because the Flash Tool won`t recognize my phone. What also is strange on my phone, if I disconnect my phone from my pc, my phone is still "charging" and it doesn`t change until I reboot.
I`m open for any suggestions which could solve this problem.
My G3 is a European modell, with 32GB. Current version is V30C and it was rooted with kingroot for this "two apps on screen" thing.
