So, I cant seem to be able to connect my G2 to the PC via USB cable. I get "usb device not recognized" error, and when looking for the device via LGPC Suite, it says driver not installed and attempts to re-install the driver to no avail. Im using Win 7 64 bit. Here's what Ive done to attempt to fix it:
Tried uninstalling and reinstalling both the driver and LGPC Suite in my normal user account and in admin admin account.
Redownloaded both driver and LGPC Suite and doing the above.
Tried 3 different USB cables.
Tried 2 different USB ports.
Yes, Im changing the connection options on the phone from MTP and LG Software.
Phone charges normally over USB.
I *can* however connect to LGPC Suite via wifi successfully.
Any ideas? Im stumped.

Sorry for bumping old thread, but have you found a solution? I found my self in exactly same situation as you describe.
Phone is in LG Software mode
LG Suite can find the phone over Wi-fi, other modes work through USB.
Tried on two different computers, with win7/win8 respectively.
Stock EU ROM, just bought it.
Tried different USB ports.
Yet PC doesn't recognize it :/
EDIT: Never mind, solved it by following the following instructions in another thread:

You must be on 64 bit windows. Not even on 64bit, Still try this...
1) Uninstall LG Drivers, LG PC Suite and anything you see named LG. Restart PC.
2) Install latest LG Driver from this post (step 4)
3) Install Optional MTP Driver from this post (step 4)
4) Open Windows Device Manager (just to watch whats happening.)
5) Disconnect Internet (To avoid stupid online WDM drivers)
6) Connect phone with Usb and let drivers install automatically. Give it some time to install drivers keeping watch on Device Manager window.
7) Keep changing USB connect modes to all modes one-by-one on Phone and let drivers install.
You should see MTP drivers installed now. If this does not help, cant think of anything else. If this works, press THANKS button
EDIT: Connect USB at backside of pc, directly to USB on pc motherboard.

I have a rooted Verizon LG G2 that I somehow screwed up when going to Lollipop from KitKat. I have lost my 3G and LTE capabilities, thus no data unless connected to WiFi. From what I have read, it sounds like I need to try to revert to stock and start over. This is where I am having my major issues. I have tried the .kdz and the .tot methods of returning my phone to stock firmware. Upon placing my phone into Download mode on both a PC and a laptop (Windows 7 on both) my phone is at best recognized as a USB Modem Phone ADB Port, not the Port (COM LPT) that is required for either method to work. What can I do to get my phone to register as the Serial Port so that the LG Flash Tools will recognize it? (I have installed the most recent LG VZW Drivers and have uninstalled other drivers without any changes). Thanks
!bump having the same issue myself

Screenshots, exact details, please. Maybe it's a simple driver fix or maybe it's a scary Qcomm diag mode issue (hopefully the good one). You've installed the latest drivers from LG, yes (3.12 or 3.13)? You often (usually) have to manually update the driver in Device Manager. Nothing listed under COM ports at all while the phone is in download mode?
Standard what-have-you:
Install latest LG Drivers (can be downloaded from LG support website).
Open Windows Device Manager and look under COM Ports for the LG device. Right-click on device, choose properties, and change the COM port to Port 41. Even if it says that port is already in use, do it anyways. This the port that LG Flash Tools uses to flash their stock images.
NOTE: Some tutorials will tell you to set your computers date back to make LG Flash Tools work: that is incorrect with version 1.8x and unnecessary, ignore them.
After the port is set to 41, unplug the USB cable from the phone, then open up LGFlashTools.exe. Select the correct VS980 .dll file and select the TOT file to flash. Press OK. Then press the yellow arrow in the upper left of the main LG Flash Tools window. It will think for a minute, then say Ready! or some such crap in the upper left port 41 box. Then you plug the USB cable back into the phone and it will start flashing. You do not have to wait until it reaches 100%, only until the phone fully boots up and presents you with the LG Setup Wizard (1st thing it asks for is your language preference). After you get there just close the LG Flash Tools program.
If it does not successfully flash:
-- Make sure you connect the USB cable directly to a motherboard port, do *not* use a hub.
-- Do not connect or remove others devices to your system until the flashing is done, as I've had that bork my flash before.

LG site has latest VS980 drivers as 2.18
When I plug in my phone and download mode starts, Device Manager will intially show it under 'Other Devices' as 'Android'. Then it will load a generic Android ADB driver. If I hijack the driver install I can manually install an LG Port (COM and LPT) driver, but it will error upon install. It will still show with a yellow exclamation point. I can still change the Port here, but its the error that I think is holding everything up.
I've tried both the kdz and tot method to no avail.
I've tried on a PC, both front and rear USB ports, and a laptop (both USB ports) and no luck.
Any other info I can provide to you? Thanks for helping

Stick to the rear USB ports on the PC, definitely. I've sometimes had it work via a hub, sometimes not (more often not).
So you've chosen the LGE AndroidNet driver, yes? And at this point you don't have the LG Flash Tools open yet, yes? It's best to keep that closed until after you've set the COM port to 41 (probably safe either way, but it does flag a conflict in com ports sometimes, which IME, doesn't matter, but still). While leaving the phone plugged into the USB, is that exclamation point still there after reboot? Screenshots? What error message does it provide under the devices status when you choose Right-click->Propertires(/Alt+Enter)?
Info
I've attached screenshots of the driver error as I install it and its properties. I've also attached shots of using the kdz method showing that nothing is detected when I press the phone information button, and also a shot of the error saying phone is disconnected when starting the flash process.

Oh gosh, I'm sorry, I didn't see this reply! XDA sometimes notifies me of replies, sometimes it doesn't. Often it doesn't, grrrr! Are you still stuck here? lol. crap, so sorry.
EDIT:
Oh, when I was mentioning port 41 I think was thinking LG Flash Tools for TOT files, no the 2014 version (which I haven't used in a while).
But that's moot, thanks to the 'device cannot start' error. This should put it into perspective:
- Uninstall all the drivers for that, all LG drivers, all Android drivers, kill 'em all -- this includes uninstalling all LG smartphone software, too. (Note: using something like UninstallTool is always best (IObit has a bloatware-laden tool like that that's free), but surely the Windows Installer should uninstall fine.)
- Reboot.
- Reinstall LG Drivers with their installer.
- Boot device into Android then plug in USB.
Windows should do the usual finding drivers rigamarole, and if it's taking a long time (more than 30 seconds or so), unplug device, the Windows add drivers dialogs should disappear, then plug it back in.
- Check Device Manager to make sure the drivers automatically loaded up, check the details on each of the drivers to make sure it's the LG driver (since you should have no other LG or Android drivers installed at this point it should be).
- If exclamation point next to device, the do the update driver thing and choose the correct LG driver.
- Reboot Windows.
- Unplug device.
- Put device in 'Download Mode' and connect USB (use motherboard ports if on desktop, not hub or case ports; never had port problem on laptop).
- Check Device Manager to see if drivers auto-found it (usually not, for me).
- Update them to LG drivers.
Is the driver still throwing up errors at this point?
Oh, when in Device Manager, select the device, then choose from the menubar View->Device by Connection. It will show the other drivers loaded for that device, and more importantly, it will show just where the device is connected to. A screenshot of that would be mucho helpful if your problem still persists.
Again, sorry I didn't get back to you. D:
Ha ha, I wasn't notified of this either. I never did get it to work. Because what I was really looking for was to get my radios working again, I had another member suggest going to a ;stock-ish' rom and flashing it (xdabbeb) along with the 12b bootstack. Lo and behold this worked for me. I was able to get my phone to show up via ADB so that I could push the files over. I never could get the .tot or .kdz to work, but I don't have the need to continue on at this point.
Thanks for your help though!
hello BEEVE i have screwed my lg g2 in the same way so can you please tell me how did you fix it or give me a link or something anything is fine
thanks in advance
I ended up flashing to a Rom that was based on stock LG. Been awhile so I don't remember. It seemed to help after a while. I also used the LTE Discovery app whenever I wasn't using my phone. The thought was that it would trick it into working. I think what actually ended up working was time. It just eventually started working better. Maybe a combination of everything, I don't know. I no longer use the phone so it's a little sketchy.
my sprint LG G2 LS980 doesn't want to mount my otg. and it doesnt want to start adb sideload.
im currently going through this bootloop or hell of a time trying to restore phone. it doesnt recognize my phone on my computer no drivers want to install it . The drivers for this phone is installed and on here properly but it doesnt want to pickup my phone but in TWRP 2.7.0.0 reads 84+
any help please? what can i do?
Device still nnot recognized
Ok so i've made huge steps, I got my phone into download mode and I'm so close but i can't get my g2 to get recognized in device manager to change the port.
I have all the files I need and I have LG flash tools all ready to go but I know I need to change the port in device manager to port 41, problem is i've tried both ports on my pc and wont recognize the devices, even with drivers installed already.
I've had my S4 for just about two years now, and have been looking into getting a new phone. I wanted to update it to 5.0 and back it up. My charging port went (yet again) so I bought a replacement and now it will charge like new. However, I cannot get it to connect to any PC and it won't show up in devices.
Things I have tried to remedy this:
-Unistalled/reinstalled newest drivers
-Uninstalled/reinstalled newest Kies
-Four different cables (all of which claim to be OEM, one IS OEM)
-Multiple USB ports on two PCs (Win 7, Win 10) and an iMac
-Checked all connections of new charging port
-Changed USB settings to MTP, MTP+ADB
As I said, I have run out of options. I can only get this thing to charge when connected to a computer, no data. It won't even show up under Device Manager or as a USB storage device.
Put ur phone in download mode then try connecting if ur PC didn't find ur phone it maybe the problem with ur phones USB port

that didn't work either. The charging port is brand new, and also a brand new cable. Any other suggestions?
Try flashing your device with the default rom
how would I do that? I can't connect it to PC to back it up or download a ROM
I am trying to recover the data from my old bootlooping LGV20. My drivers are updated. When I plug my current, working LGV20 into the computer, the phone is immediately recognized and the driver is listed as LG v4.2.0, the most current in Device Manager. The phone is labled as its model number in Devices and Printers. When I plug in my old V20 (which has full access to stock recovery and download mode but does not boot) the computer recognizes something is plugged in, but in Device Manager the device doesn't show up. In Devices and Printers the phone shows up, but as "LGE Android Phone".
Summary:
When a working LGV20 is plugged in, it is recognized and the latest 4.2.0 driver is used.
When the bootlooping phone is plugged in and completely off, it is only recognized as "LGE Android Phone"
Not recognized in Recovery mode
Because of this issue, I cannot use adb on the phone to recover my data.
The phone is stock, non-rooted, android 7, LG-VS995. I have the usb debugging option in the recovery menu though the phone bootloops when this is selected.
ADB installed via 15 second installer and SDK.
"ADB Devices" returns nothing.
When in Download mode, "Fastboot devices" returns nothing.
This issue was repeated on a second computer.
USB 2.0 and 3.0 tried.
The phone is recognized in LGMobileSupportTool
In Download mode the phone is recognized as "LGE AndroidNet" in Devices and Printers and as a COM41 port (changed from 7) in Devices and printers.
What do? I'm at a loss and it feels like I've tried everything.
Edit: I've successfully dumped the phone via LGUP, tried flashed a new image, phone is still bootlooping. Is there any way I can browse the userdata dump file?
