Hi,
Yesterday I have flashed a 6.0 ROM and right afterwards a supersu on my G Pad.
I guess something got messed up in the process because now I can't boot the ROM and not even boot into recovery.
I've tried to get into download mode using LG PC suite, but without success. someone has an idea how I can maybe save the tablet?
here is the error that I get :
I assume you have the V500 variant? If you go through the motions of putting it in Download mode through the hardware keys (I don't know if it's the same as on my VK810 variant), does it show up in Windows' Device Manager as "LGE..." in both the Modem and Ports section? If so, try flashing a TOT or KDZ made for your variant.

I don't see it under ports.
maybe I need a driver that will match win10?

What about under Modem? If it shows up under Modem then it might be worth a try flashing a KDZ with LG Flash Tool 2014.
I've never had to get a different driver package for different flavors of Windows for my LG devices. I've used the same packages on 7, 8.1 and 10 without any trouble. I don't know if things are different with non-Verizon LG devices, however, but I doubt it since LG is the one who does the driver work. I always go straight to LG's or in my case Verizon's website for the latest driver for my devices.
Are there anything listed in Device Manager as Unknown Device? If not, then it's not likely installing a different driver will produce a different result, as if Windows can't even see the device as unknown, then installing the driver won't help, but it can't hurt to try the latest driver version if you haven't already. Reboot after installing the driver and use the original USB cable and preferably with a USB 2.0 port that comes straight off your PC's motherboard (or on the back of the PC) and not through a USB hub.

It doesn't show under modem as well . I really don't know what else I can try.
I even tried to connect it on a win8.1 machine , but the tablet was not recognized as well.

Are you using the original USB cable that came with the device? After you install the driver, reboot the PC without the device connected, then go through the motions of putting the device in Download mode and connect the device to a USB 2.0 port (preferred over USB 3.x) that comes directly off the PC's motherboard - not through a USB Hub.
Give the PC up to 10 minutes to load the driver you had previously installed. Every time you connect a device for the first time to a different USB port, it has to load the driver again, and depending on various factors can take anywhere from 30 seconds to 10 minutes. After that amount of time if the Device Manager still isn't showing the device in the Modem and Port sections, then I don't have any idea what else to try either.

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?...

Thanks for the reply. I am using Windows 7 Home Edition 64 Bit and had had a look for the ACER Composite ADB Interface in Device Manager and it wasn't there. Post #18 in the thread you linked to, I have no idea what kdz file I would need. Does this method need the USB to working?
Thanks for the reply and help.
I have D85520T_00.kdz and D85520U_00.kdz files. Can someone tell me if these are OK for my phone (and latest) and what the differences between the two are (apart from the file names?) Thanks again.
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...

... 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.

my oneplus 3 does not connect to my pc. I have tried turning on and off developer options, turn off and on oem unlocking and usb debugging. I change the usb connection to mtp from charging but does not change. Also does not recognize it when i connect to pc. Also does not pop up on status bar and i checked portable devices. I also tried installing the oneplus drivers. i am on Android 7.0 freedomos-2.5. Any way to fix this issue? i might try to update freedomos because im on a old version of it.:crying:
Windows? If, yes windows drivers are the problem.
Try to other pc, to see if it works., first.

I have tried it on both my PC and laptop with both windows 10. Does not work. My PC also has windows 7 still seems to not work. Are there any other drivers i might be missing?
i have also done some research that you should update your drivers from device manager. I dont see anything related to my device. i went to portable devices nothing and i dont have a other devices section in device manager. Any help?
What recovery?
Try to flash latest twrp. I use blu-spark by eng-stk. You can fla**** thru recovery or Flashify app.

ive also found out theres no kedcom driver when i go to fastboot. i even reinstalled adb drivers to insure its there but it does not pop up.
You'll need to remove drivers reboot, install correct drivers, reboot and then be nice to everyone you ever meet and it'll show up. It's a real pain but you can get there. XDA tutorial all the way there!
I once have kind of youre problem connecting to my laptop (win.10). But, at work, on that laptop, connection was ok (win.7).
I reinstal windows 10 and connection works fine, since.
I allways use latest TWRP & version of rom. I can't tell for sure what it's goin on with youre phone.
If i was in youre situation i format my phone (this will erase ALL in youre phone). And if PC still does not see the phone reinstall windows.
Also: Try a different cable.
A cheap cable could have a charging pin layout but lack data pins connections.
9 out of 10 issues with connecting to PC and getting odd behaviours is due to a bad/wrong cable.

Find the excellent tutorial here on drivers.
For some reason my phone didn't show up but was able to receive commands. It was frustrating because I wanted to use the all in one XDA product but couldn't.
Even if you installed drivers they can be broken!
Do drivers from scratch per xda tutorial. Don't forget reboot!
Try different cables and usb ports! My front ones never seem to work!
Don't just try fastboot commands also try adb. Like I said mine wasn't seen properly yet it took the commands.
Unless your windows is a years old install it shouldn't require reinstall.
Factory phone reset might help.
Best of luck!
Hello friends!
New registered user here but have already read tons of threads regarding G3 troubleshooting. Anyway, have decided to post this problem and if a similar situation has already been posted (and solved), please provide link.
For some strange reason, my G3 have decided to stay in the LG logo (I understand that this is the so-called boot-loop). This happened when the phone suddenly restarted while watching a YT vid and the battery still at 30%++. The phone just keeps on restarting until such a time that it never got pass the LG logo.
Here are the things that I have already tried to no avail:
1. Enter Hard Reset page via hardware keys (Power + Vol Up buttons). Have chosen "Yes" to hard reset device but alas, it never got pass the LG logo.
2. Downloaded PC suite, KDZ flashtool, and LGUP. Installed all three software. Connected G3 to PC and entered download mode (Vol Down while inserting USB cable). Unfortunately, unable to fully use either of the three software since the PC cannot detect G3.
Number 2 is quite strange since I have downloaded and installed all G3 drivers. This I know since a friend of mine who owns a working G3 unit was detected by the computer and can sync with the PC suite.
For some strange reason, everytime I connect my broken G3 to the computer, it is not detected by the PC and was not even listed in the device manager.
Any help and advise would be highly appreciated
I already downloaded all necessary tools (KDZ, LGUP, and flashtool) to flash the ROM but I need the PC to see the G3 unit to be able to do so.
By the way, before the bootloop scenario: the debugging (or is it developer?) options are disabled and I'm not sure if the bootloader is locked or unlocked.
I hope all this info is of any use.
Thanks a lot in advance
Have you tried simpler solutions first? Like, trying another USB ? Or another USB port from your pc? This maybe hardware related rather than software. You should try that before anything else. (Maybe you did?)

Thanks for the reply. Yup, have done those. Tried a different cable, different USB port, and borrowed a working G3 unit. The good G3 unit was detected by the PC but when I connect my broken G3 (same cable and same USB port), the PC does not detect it (not even listed in device manager).
Because of this hurdle, I couldn't flash with LGUP (it states no handset was connected). The KDZ flashtool basically says the same message.
By the way, my debugging options are disabled before this whole problem started. Could that be a reason why the PC won't detect the unit?
Hi there. Sorry if I sound dumb. I'm new to this whole thing and this was supposed to be my first experience with flashing custom ROMs and stuff like that. I was planning to get ready to install LineageOS on my Nexus 7 using a Windows 10 PC. Unfortunately, things quickly went south.
My first roadblock was the tablet not being recognised by fastboot. I checked online for a bit and from what I could gather, the solution was to install the Google USB drivers using device manager. I went into device manager, right clicked my Nexus 7 in "portable devices", selected "update driver" and chose the Google USB driver I downloaded from the official Android developers website. I'm not sure if this is relevant but the tablet was in fastboot mode when I did this. From that point on, my tablet is no longer recognised and it just keeps saying "device descriptor request failed" whether it's in fastboot or normal mode, and regardless of which USB mode I choose.
I tried uninstalling the driver, factory resetting, WugFresh NRT, and using different cables and USB ports. I checked for all sorts of solutions but they either didn't help or they require an unlocked bootloader (which was the very first thing I tried to do before finding out I needed to install the driver for fastboot to recognise the Nexus 7). Does anyone here know of a solution to get this working again? I'm completely stumped on what to do.
EDIT: I tested with a Chromebook and an old Windows 7 PC I had lying around. Neither could detect my Nexus 7 and the W7 PC even said it failed to install the driver as soon as I plugged it in. It seems that the driver update screwed up my tablet somehow and I have no idea how to fix it. I really don't understand how this could have happened considering I followed Google's own instructions for updating the driver.
Does anyone perhaps have a copy of the OEM driver for the 2013 N7 Wi-Fi (flo) model? ASUS don't distribute the driver on their website anymore and I'm out of ideas.

Review this thread and the solutions.
After you have fixed it, you can easily install a new custom ROM with two steps:
RESTOCK - installs USB drivers and unlocks it, latest official stock ROM
CROSS - various custom ROMs, 1-click installation, TWRP, incl root

Thanks for the response. I don't think I'll have enough time to try this today but I might as well ask. Do any of these fixes work without needing a USB connection to a PC, or if they do, do they require adb and fastboot to work? Because if so, I won't be able to use them since my USB data connectivity is completely busted no matter what I plug my Nexus into.

I just ran the RESTOCK 1 script and it worked wonders! My tablet's USB connectivity has been fixed and as an added bonus, my bootloader is now unlocked. I'll be continuing the process in Linux on my Pixelbook since it doesn't require any driver installations as far as I know. Thank you so much! You're a life saver!
