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 son attempted a flash without reading through much.. he had the newest firmware and now it won't boot into anything but TWRP and what i think is download mode (it just shows the LG logo, but I do have adb access). The issue is in these modes, I can't get windows to recognize the device to be able to assign it to port number 41. I can manually pick a driver, but then it only shows up as that driver, not the phone on the devices location in Windows. .. So, the LGFlashtool doesn't recognize it and nothing works. I've even tried assigning it the LGE Android Platform USB Serial port driver, set to port 41 and it still won't work.
Any suggestions? Is there another method from the LGflashtool one detailed? Thank you for any advice! (this experience is enough punishment and a great lesson for my son to learn to READ and follow instructions).
This is for the AT&T model.
FIXED. Through multiple attempts and multiple threads, I ran into this thread:
http://forum.xda-developers.com/showthread.php?t=2451696
I did it through TWRP Terminal. Upon rebooting, I'd see the LG logo super fast and then nothing.. I held down power for some time, then the up volume, plugged in and I HAD DOWNLOAD MODE! whew.
From here, all is well, it shows up on devices and I can push the factory firmware. -Yay for google, yay for XDA and all the resources these forums have pooled together!.
(thanks)
Creating a troubleshooting thread to see if might be able to get some help on a big problem I'm having with my LG G2...
I'm trying to restore my VZ LG G2 to stock so that it can be returned (audio input is malfunctioning). I am currently running TWRP + CM 11 Nightlies on it.
When I enter download mode, I see the screen "Firmware Update" and it says "B99" and "Rooted" at the bottom.
When I use the R&D Test Tool + LGMobile Support Tool to try to restore to VS98011A_01.kdz, the software update runs on my computer as if it is pushing the update to the phone, but the phone itself shows no actual status change. It just sits there with 0% on the status bar.
When it finishes on my computer it says (on my computer) that the software update was successful. Unfortunately my phone boots into CM just like it normally does with all my apps and data there.
Based on some suggestions I have seen, I have tried manually changing to COM 41 and disabling the device as a modem in device manager -- does not make a difference.
I have no idea why no actual change is happening on the phone. Any suggestions?
Man, this is brutal. I thought that maybe the issue was that I was using the 3.10 LG United drivers instead of the 3.8 drivers, so I uninstalled 3.10 and installed 3.8.
Unfortunately now the LG G2 is recognized when it is in normal mode (running CM 11.0) but Windows shows "No drivers found" when I put it in download mode:
USB Composite Device: Ready to Use
CDC Serial: No drive found
CDC ECM: No driver found
LGE Android Phone: No driver found
Network Controller: No driver found
The last four all show up under "Other devices" in device manager with an exclamation.
Previously I was at least able to see the LG Android VZW etc. etc. under COM/Ports with 3.10 drivers installed.
I am burning so much time trying to figure this out. Mayday, mayday!
For anyone that may come across this thread in the future, I want to share what ultimately worked.
I followed the TOT method instructions in this thread: http://forum.xda-developers.com/showthread.php?t=2448960
It was just as easy as the KDZ method, but actually worked! Here are the two things that seemed to make a difference:
1. I installed the _Verizon_ LG drivers referenced in that thread
2. I manually changed to COM41
Following all instructions in that thread everything worked like a charm.
Hi all,
I've broken my LG G2. I made an edit to build.prop and the phone stopped working. It will display the LG logo but then the screen goes black and the LED slowly flashes green/blue. I was running stock Rogers firmware, rooted, with a stock recovery.
I've performed a factory reset. Didn't fix anything.
I have tried to connect via ADB and fastboot but the phone isn't listed as a device.
I've tried using the LG Update program. The phone connects and is recognized but fails when reaching 4%.
I've used the LG Flash Tool 2014 but that fails at 2%.
When the phone is plugged into my computers, device manager shows it as: LGE AndroidNET USB Port (Com3) and LGE AndroidNET USB Modem. There is nothing else listed. I've tried installing all the recommended drivers; there is no change.
I have no idea what to do next. I'm hoping someone here can help.

Have you tried this driver? http://www.koushikdutta.com/post/universal-adb-driver As the page states, even when the manufacture offer their own drivers, ADB still won't recognize your phone as a device, sometimes. I had a similar experience and after installing this particular driver from Koush it recognized it. Hope it helps.
I tried rooting my G2 using this guide, and seem to have f'ed up somehow.
The phone now won't boot (stuck at the "LG" screen, with rainbow LED), and I can't get into download mode.
The strange thing is that I do get into recovery mode, but it seems to exit abruptly. When I try to recover (by selecting yes twice), the Android recovery icon shows up for a couple of seconds, but then it goes back to the "LG" boot screen again.
I would be grateful for any help.
I've tried connecting to a computer with Ubuntu, as per this guide: http://forum.xda-developers.com/showthread.php?t=2582142, but I was unable to mount the phone.
It does show up in the device manager in Windows, under "Portable Devices".
I've disovered that the guide I followed for rooting was for G3 phones (and the G2 D805). I'm guessing this could be part of my problem.
But the guide said that I should be safe, since I had Lollipop. The Download mode should be able to save me if anything went wrong. But alas.
Before starting the rooting process I had the latest Lollipop update from LG (it was performing poorly, that's why I wanted to install a custom ROM).
Is it possible to save this phone? I'll probably look for a good deal on the 5X at Black Friday if I can't fix the G2, but I'd rather keep this phone working for a while anyway.
Still having trouble with this.
If I turn on the phone and connect it to a PC (with the phone stuck at the "LG" screen) it appears my the device manager on my PC, but adb.exe reports no connected devices.
no connecting to pc

How do I install these? When I plug in the phone and view properties in device manager, I can't select update or uninstall driver.
(I would insert a screenshot here, but I need to have more posts on the forum first)
EDIT: I just removed the LG drivers by uninstalling the LG software + drivers, and removing any left over drivers using Nirsoft USBDeview. Then I installed Koush’s Universal ADB Driver. But adb still reports no connected devices... I guess this device is bricked after all.

MSM8994DownloadTool.exe Won't Work For Me
I need help.
My phone is stuck on the fastboot screen, meaning I can only Power if off and into Fastboot (using the Vol+ and Power buttons). Other than that, it does nothing. I cannot get into the OS at all, which means I can't enable USB debugging or anything. Fastboot recognizes my device, which is a OnePlus Two), but ADB won't, nor will my Windows 7 PC as a USB device. With that in mind, I followed all the steps in the posted guide. I get all the way to running the "MSM8994DownloadTool.exe" and nothing happens. Its as if the Recovery Tool doesn't even see my device. So, I'm really stuck and don't know what to do.
For clarity, here's exactly what I did (see below). I get all the way to Section B, Step 2 and that's where it breaks down. There's no different line, and no process ever runs, even after waiting 30 minutes. I ran the tool as Administrator, but still no luck. Can anyone help me? Just as additional info, my Mac also does not recognize my OPT as a USB device. Also, I tried my backup USB-C cable from the OEM, with the same results.
A. Install the Certificates followed by the Qualcomm drivers.
1. Restart your computer with Driver Signature Enforcement Disabled (Advanced Startup) Let me Google it For You
2. Open the folder "qc" and install the Test Certificate in the following Stores: Trusted Root, Trusted Publisher, Third-Party Root and Personal
3. Run the Qualcomm setup wizard (also located in the qc folder)
4. When completed, restart your PC again with Driver Signature Enforcement Disabled (Advanced Startup)
5. Turn off your phone and disconnect the USB cable from the phone.
6. Hold vol-up and plug in the USB(Do not press Power button). The screen will stay black but you will hear a sound from windows that a device is attached.
7. The driver should now automatically install. If not, go to device manager and right click "Unknown Device" and click "Update Driver" Search up the QC folder and press ok. The driver should now install. (Got the RELINK issue? Take a look here: http://forum.xda-developers.com/show...1&postcount=46)
B. Flashing Process
1. Open the OnePlus2_14_A.11_151211 folder and open "MSM8994DownloadTool.exe"
2. Look if your phone is detected in the list. everything is Chinese but you will see one row with different chinese text from the rest within the list. If not, recheck if driver is detected in Device Manager (If not, go back to Step A - Line 4).
I think you have a bad download, try downloading it again and download the 3.0.2 version if you can.

I've bricked my op2 a while ago. I'm a real noob so I don't know if it will work but have you installed the adb mac drivers or try "fastboot continue" while in fastboot. Just don't give up and keep try. You have absolutely nothing to lose.

Thank you very much. I have the latest version, but still nothing. I don't know if this has anything to do with it, but my OPT wasn't being recognized as a USB device even before I screwed up. That leads me to believe my OPT USB is maybe not functional. ADB doesn't recognize it at, nor will the MP...DownloadTool.exe. I'm guessing it is just hard-bricked since I have no other way (besides USB) to interface with the device.

Try connecting your OPT to some other guys pc and see, it may be because of your pc's end that its not getting connected.
And if the same thing happens with a different pc then yeah your usb port or something is fried. Try going to service center if the same thing happens again.
